这篇文章主要是自己研究如何对底部菜单进行布局,并简单的实现点击不同"按钮"实现图片切换和背景切换的功能,最后通过PopupWindows实现弹出菜单,点击不同按钮能实现不同方法,相当于美图秀秀编辑图片的功能吧!它并没有涉及到Fragment碎片切换页面的功能,因为页面始终显示被处理的图片.这是我初学Android的一篇基础性文章和在线思想笔记,网上有很多更优秀的demo,不过也希望对大家有用~

   

首先介绍两种方法实现底部菜单点击不同图标显示选中状态的效果.

    (可参考简短文章： Android_UI_点击按钮切换背景效果实现

)

    一. 底部菜单 第一种方法

    它显示的效果如下图所示,其中底部菜单布局采用多个LinearLayout进行,点击不同"按钮"可以改变其背景图片.

               

   

首先介绍它的activity_main.xml布局：

   

1.它采用3个RelativeLayout相对布局进行,分别对应标题路径、中间显示图片和底部的菜单栏;

2.底部菜单栏由5个LinearLayout水平布局组成,每一个LinearLayout都由ImageView和TextView组成.

    代码如下：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  xmlns:tools="http://schemas.android.com/tools"  android:id="@+id/container"  android:layout_width="match_parent"  android:layout_height="match_parent"  tools:context="com.example.touchimagetest.MainActivity"  tools:ignore="MergeRootFrame" >   <!-- 顶部路径 -->  <RelativeLayout     android:id="@+id/MyLayout_top"    android:orientation="horizontal"     android:layout_width="fill_parent"    android:layout_height="40dp"     android:layout_alignParentTop="true"    android:gravity="center">    <TextView      android:id="@+id/textView1"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:textSize="15sp"      android:text="显示图片操作" />  </RelativeLayout>  <!-- 底部按钮 -->  <RelativeLayout    android:id="@+id/MyLayout_bottom"    android:orientation="horizontal"     android:layout_width="fill_parent"    android:layout_height="50dp"    android:layout_alignParentBottom="true"    android:background="@drawable/image_toolbar_bg"    android:gravity="center">    <LinearLayout       android:layout_width="match_parent"      android:layout_height="match_parent"      android:orientation="horizontal"      android:layout_alignParentBottom="true" >             <LinearLayout         android:id="@+id/layout_watch"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_weight="1"        android:gravity="center"          android:orientation="vertical" >          <ImageView            android:id="@+id/image_watch"            android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:padding="3dp"           android:src="@drawable/tab_watch_btn" />          <TextView            android:id="@+id/textview_watch"          android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:text="查看"            android:textColor="#ffffff"            android:textSize="10sp" />        </LinearLayout>              <LinearLayout         android:id="@+id/layout_increase"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_weight="1"        android:gravity="center"          android:orientation="vertical" >          <ImageView            android:id="@+id/image_increase"            android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:padding="3dp"           android:src="@drawable/tab_increase_btn" />          <TextView            android:id="@+id/textview_increase"          android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:text="增强"            android:textColor="#ffffff"            android:textSize="10sp" />        </LinearLayout>              <LinearLayout         android:id="@+id/layout_effect"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_weight="1"        android:gravity="center"          android:orientation="vertical" >          <ImageView            android:id="@+id/image_effect"            android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:padding="3dp"           android:src="@drawable/tab_effect_btn" />          <TextView            android:id="@+id/textview_effect"          android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:text="特效"            android:textColor="#ffffff"            android:textSize="10sp" />        </LinearLayout>            <LinearLayout         android:id="@+id/layout_frame"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_weight="1"        android:gravity="center"          android:orientation="vertical" >          <ImageView            android:id="@+id/image_frame"            android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:padding="3dp"           android:src="@drawable/tab_frame_btn" />          <TextView            android:id="@+id/textview_frame"          android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:text="相框"            android:textColor="#ffffff"            android:textSize="10sp" />        </LinearLayout>             <LinearLayout         android:id="@+id/layout_person"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_weight="1"        android:gravity="center"          android:orientation="vertical" >          <ImageView            android:id="@+id/image_person"            android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:padding="3dp"           android:src="@drawable/tab_person_btn" />          <TextView            android:id="@+id/textview_person"          android:layout_width="wrap_content"            android:layout_height="wrap_content"             android:text="美白"            android:textColor="#ffffff"            android:textSize="10sp" />        </LinearLayout>       </LinearLayout>    </RelativeLayout>  <!-- 显示图片 -->  <RelativeLayout    android:id="@+id/Content_Layout"     android:orientation="horizontal"    android:layout_width="fill_parent"     android:layout_height="fill_parent"    android:layout_above="@id/MyLayout_bottom"     android:layout_below="@id/MyLayout_top"    android:background="#EFDFDF"    android:gravity="center">    <ImageView      android:id="@+id/imageView1"      android:layout_width="fill_parent"      android:layout_height="fill_parent"      android:layout_gravity="center_horizontal"      android:scaleType="matrix" />  </RelativeLayout></RelativeLayout>

  此时你需要注意的是为每个LinearLayout中ImageView指定src时并不是原图片,而是drawable中的xml文件,如<ImageView android:id="@+id/image_watch".. />.

    同时每个drawable中的xml文件对应每个相应的按钮,上图中effect(效果)、increase(增强)、frame(相框)、watch(查看)、person(美白).其中每个格式基本如下,如tab_watch_btn.xml：

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android" >    <item android:drawable="@drawable/image_icon_watch_sel" android:state_selected="true"/>    <item android:drawable="@drawable/image_icon_watch_sel" android:state_pressed="true"/>     <item android:drawable="@drawable/image_icon_watch_nor"/> </selector>

其中state_selected表示"选中"状态,state_pressed表示"点击"效果,而最后的<item android:drawable="@drawable/image_icon_watch_nor"/> 表示默认情况显示图片,原图片如下：

    同时设置选中状态"按钮"的背景加黑效果,在drawable中添加selector_tab_background.xml文件:

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android" >  <item android:drawable="@drawable/image_home_layout_bg" android:state_pressed="true"/>      <item android:drawable="@drawable/image_home_layout_bg" android:state_selected="true"/>  </selector>

//自定义变量private LinearLayout layoutWatch;             //查看图片private LinearLayout layoutIncrease;           //增强图片private LinearLayout layoutEffect;               //图片特效private LinearLayout layoutFrame;              //图片边框private LinearLayout layoutPerson;             //图片美白private ImageView imageWatch;    private ImageView imageIncrease;  private ImageView imageEffect;  private ImageView imageFrame;  private ImageView imagePerson;

//创建活动@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    //布局    layoutWatch = (LinearLayout) findViewById(R.id.layout_watch);    layoutIncrease = (LinearLayout) findViewById(R.id.layout_increase);    layoutEffect = (LinearLayout) findViewById(R.id.layout_effect);    layoutFrame = (LinearLayout) findViewById(R.id.layout_frame);    layoutPerson = (LinearLayout) findViewById(R.id.layout_person);    //图标     imageWatch = (ImageView) findViewById(R.id.image_watch);    imageIncrease = (ImageView) findViewById(R.id.image_increase);    imageEffect = (ImageView) findViewById(R.id.image_effect);    imageFrame = (ImageView) findViewById(R.id.image_frame);    imagePerson = (ImageView) findViewById(R.id.image_person);    //初始化布局    initView();    //按钮一 监听事件 查看图片    layoutWatch.setOnClickListener( new OnClickListener() {    @Override    public void onClick(View v) {      //设置背景图片加深    Toast.makeText(MainActivity.this, "点击按钮1", Toast.LENGTH_SHORT).show();    layoutWatch.setBackgroundResource(R.drawable.selector_tab_background);    //设置图标选中情况    layoutWatch.setSelected(true);    layoutIncrease.setSelected(false);    layoutEffect.setSelected(false);    layoutFrame.setSelected(false);    layoutPerson.setSelected(false);    }    });    //按钮二 监听事件增强图片    layoutIncrease = (LinearLayout) findViewById(R.id.layout_increase);    layoutIncrease.setOnClickListener( new OnClickListener() {    @Override    public void onClick(View v) {    layoutIncrease.setBackgroundResource(R.drawable.selector_tab_background);    //设置图标选中情况    layoutWatch.setSelected(false);    layoutIncrease.setSelected(true);    layoutEffect.setSelected(false);    layoutFrame.setSelected(false);    layoutPerson.setSelected(false);    }    });    //按钮三 监听事件图片特效    layoutEffect = (LinearLayout) findViewById(R.id.layout_effect);    layoutEffect.setOnClickListener( new OnClickListener() {    @Override    public void onClick(View v) {    //设置背景图片    layoutEffect.setBackgroundResource(R.drawable.selector_tab_background);    //设置图标选中情况    layoutWatch.setSelected(false);    layoutIncrease.setSelected(false);    layoutEffect.setSelected(true);    layoutFrame.setSelected(false);    layoutPerson.setSelected(false);    }    });    //按钮四 监听事件图片相框    layoutFrame = (LinearLayout) findViewById(R.id.layout_frame);    layoutFrame.setOnClickListener( new OnClickListener() {    @Override    public void onClick(View v) {    //设置背景图片    layoutFrame.setBackgroundResource(R.drawable.selector_tab_background);    //设置图标选中情况    layoutWatch.setSelected(false);    layoutIncrease.setSelected(false);    layoutEffect.setSelected(false);    layoutFrame.setSelected(true);    layoutPerson.setSelected(false);    }    });  //按钮五 监听事件图片美白    layoutPerson = (LinearLayout) findViewById(R.id.layout_person);    layoutPerson.setOnClickListener( new OnClickListener() {    @Override    public void onClick(View v) {    //设置背景图片    layoutPerson.setBackgroundResource(R.drawable.selector_tab_background);    //设置图标选中情况    layoutWatch.setSelected(false);    layoutIncrease.setSelected(false);    layoutEffect.setSelected(false);    layoutFrame.setSelected(false);    layoutPerson.setSelected(true);    }    });}//初始化布局private void initView(){  imageWatch.setImageResource(R.drawable.tab_watch_btn);  imageIncrease.setImageResource(R.drawable.tab_increase_btn);  imageEffect.setImageResource(R.drawable.tab_effect_btn);  imageFrame.setImageResource(R.drawable.tab_frame_btn);  imagePerson.setImageResource(R.drawable.tab_person_btn);}

    二. 底部菜单 第二种方法

    其中activity_main.xml中布局与第一个相同,不同的是在xml中就指定drawable-hdpi中原图片名,因为它不在调用drawable如 tab_watch_btn.xml文件,而使用代码直接操作. 其中5个LinearLayout一个如下所示：

<LinearLayout      android:id="@+id/layout_watch"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_weight="1"     android:gravity="center"       android:orientation="vertical" >       <ImageView         android:id="@+id/image_watch"         android:layout_width="wrap_content"         android:layout_height="wrap_content"          android:padding="3dp"        android:src="@drawable/image_icon_watch_nor" />       <TextView         android:id="@+id/textview_watch"       android:layout_width="wrap_content"         android:layout_height="wrap_content"          android:text="查看"         android:textColor="#ffffff"         android:textSize="10sp" />  </LinearLayout>

    此时它的文件夹结构如下图,drawble没有设置背景加深和加载图标的xml文件：

    同时5个LinearLayout(查看、增强、特效、相框、美白)设置触屏响应事件：

layoutWatch.setOnTouchListener(new OnTouchListener() {  @Override  public boolean onTouch(View v, MotionEvent event) {       if(event.getAction() == MotionEvent.ACTION_DOWN) {         //按下背景图片       layoutWatch.setBackgroundResource(R.drawable.image_home_layout_bg);      layoutIncrease.setBackgroundResource(R.drawable.image_home_layout_no);      layoutEffect.setBackgroundResource(R.drawable.image_home_layout_no);      layoutFrame.setBackgroundResource(R.drawable.image_home_layout_no);      layoutPerson.setBackgroundResource(R.drawable.image_home_layout_no);      //设置按钮图片      imageWatch.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_watch_sel));      imageIncrease.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_increase_nor));       imageEffect.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_effect_nor));       imageFrame.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_frame_nor));       imagePerson.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_person_nor));     }    return false;     }   });

    需要注意的是网上下面这段代码仅实现点击一下图片变换的效果,而如果想要实现长显需要如我上面的所示.还见到一个使用Radio实现该效果,当点击一次时判断是否选中并显示相应图片.而使用FragmentTabHost实现同样效果,我不知其原理~

bottomReturnBtn.setOnTouchListener(new OnTouchListener() {      //这段代码仅仅实现点击一次改变图标功能  public boolean onTouch(View v, MotionEvent event) {      Button upStepBtn = (Button) v;      if(event.getAction() == MotionEvent.ACTION_DOWN){        upStepBtn.setBackgroundResource(R.drawable.bottom_sub_order_btn);      }else if(event.getAction() == MotionEvent.ACTION_UP){        upStepBtn.setBackgroundResource(R.drawable.bottom_return_check);        finish();       }      return false;    }  });

    三. PopupWindow实现弹出菜单

     

然后讲解如何通过PopupWindow实现下面的功能.效果如下图所示,简单实现PopupWindow功能可结合下面两篇文章：

android之popupWindow在指定位置上的显示

[android开发] 使用PopupWindow实现页面点击顶部弹出下拉菜单

    首先,为PopupWindow设置动画效果,在res文件夹下添加文件夹anim,然后添加anim_entry.xml文件：

<?xml version="1.0" encoding="utf-8"?>  <set xmlns:android="http://schemas.android.com/apk/res/android">  <translate    android:fromXDelta="0"    android:toXDelta="0"    android:fromYDelta="120"    android:toYDelta="0"    android:duration="500" /></set>

    它是出现效果：从菜单栏底部向上弹出,同时添加anim_exit.xml:

<?xml version="1.0" encoding="UTF-8"?>  <set xmlns:android="http://schemas.android.com/apk/res/android" >    <!-- 透明度消失 -->  <alpha     android:fromAlpha="1.0"     android:toAlpha="0.0"     android:duration="200" /></set>

    最后在res/values文件夹styles.xml中添加动画效果,通过调用name="AnimationPreview"可以实现动画：

<!-- 定义popupwindows动画效果 --> <style name="AnimationPreview">       <item name="android:windowEnterAnimation">@anim/anim_entry</item>       <item name="android:windowExitAnimation">@anim/anim_exit</item>   </style>

    然后你需要自定义弹出PopupWindow的布局xml文件,如popup_effect.xml：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  android:layout_width="wrap_content"    android:layout_height="wrap_content" >      <LinearLayout      android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:layout_alignParentBottom="true"      android:background="@drawable/image_button_bg_left"      android:orientation="vertical" >      <LinearLayout        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_horizontal"        android:layout_marginTop="5dp"        android:orientation="horizontal" >              <LinearLayout          android:id="@+id/layout_effect_hj"        android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_margin="2dp"          android:layout_weight="1"          android:orientation="vertical" >          <ImageView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal"            android:layout_marginTop="1.0dip"            android:src="@drawable/image_effect_hj" />        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal"            android:layout_marginTop="1.0dip"            android:shadowColor="#ff000000"            android:shadowDx="1.0"            android:shadowDy="1.0"            android:shadowRadius="1.0"            android:text="怀旧"            android:textColor="#ffffffff"            android:textSize="13.0dip" />        </LinearLayout>          <LinearLayout          android:id="@+id/layout_effect_fd"        android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_margin="2dp"          android:layout_weight="1"          android:orientation="vertical" >          <ImageView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal"            android:layout_marginTop="1.0dip"            android:src="@drawable/image_effect_fd" />          <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal"            android:layout_marginTop="1.0dip"

android:textColor="#ffffffff"            android:textSize="13.0dip" />        </LinearLayout>        <LinearLayout          android:id="@+id/layout_effect_gz"        android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_margin="2dp"          android:layout_weight="1"          android:orientation="vertical" >          <ImageView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal"

   <LinearLayout          android:id="@+id/layout_effect_sm"        android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_margin="2dp"          android:layout_weight="1"          android:orientation="vertical" >          <ImageView            android:layout_width="wrap_content"            android:layout_height="wrap_content"

</LinearLayout>  </RelativeLayout>

    它的在Xml中Graphical Layout显示效果如下图所示：

    添加5个自定义变量：

//弹出按钮private PopupWindow popupWindow1;     private PopupWindow popupWindow2;private PopupWindow popupWindow3;private PopupWindow popupWindow4;private PopupWindow popupWindow5;

    然后当点击"相框"布局LinearLayout时,添加代码如下(其他类似)：

//按钮四 监听事件图片相框layoutFrame.setOnClickListener( new OnClickListener() {  @Override  public void onClick(View v) {    //载入PopupWindow    if (popupWindow4 != null&&popupWindow4.isShowing()) {        popupWindow4.dismiss();        return;      } else {        initmPopupWindowView(4);   //number=4      int[] location = new int[2];        v.getLocationOnScreen(location);       Toast.makeText(MainActivity.this, ""+location[0], Toast.LENGTH_SHORT).show();      popupWindow4.showAtLocation(v, Gravity.NO_GRAVITY, location[0], location[1]-popupWindow4.getHeight());    }  }});

    其中initmPopupWindowView(int number)为自定义函数,参数对应的是点击LinearLayout的序号,点击"按钮"4即传入数字4：

public void initmPopupWindowView(int number) {      View customView = null;    // 获取自定义布局文件      if(number==1) { //查看      customView = getLayoutInflater().inflate(R.layout.popup_watch, null, false);        // 创建PopupWindow实例  (250,180)分别是宽度和高度        popupWindow1 = new PopupWindow(customView, 250, 280);       // 设置动画效果 [R.style.AnimationFade 是自己事先定义好的]        popupWindow1.setAnimationStyle(R.style.AnimationPreview);        // 自定义view添加触摸事件        customView.setOnTouchListener(new OnTouchListener() {          @Override          public boolean onTouch(View v, MotionEvent event) {            if (popupWindow1 != null && popupWindow1.isShowing()) {              popupWindow1.dismiss();              popupWindow1 = null;            }            return false;          }        });      }     if(number==2) { //增强     customView = getLayoutInflater().inflate(R.layout.popup_increase, null, false);       popupWindow2 = new PopupWindow(customView, 450, 150);     // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法          popupWindow2.setFocusable(true);         // 设置允许在外点击消失          popupWindow2.setOutsideTouchable(true);        popupWindow2.setAnimationStyle(R.style.AnimationPreview);         // 自定义view添加触摸事件         customView.setOnTouchListener(new OnTouchListener() {           @Override           public boolean onTouch(View v, MotionEvent event) {             if (popupWindow2 != null && popupWindow2.isShowing()) {               popupWindow2.dismiss();               popupWindow2 = null;             }             return false;           }         });       }    if(number==3) { //效果      customView = getLayoutInflater().inflate(R.layout.popup_effect, null, false);        popupWindow3 = new PopupWindow(customView, 450, 150);      // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法         popupWindow3.setFocusable(true);        // 设置允许在外点击消失         popupWindow3.setOutsideTouchable(true);       popupWindow3.setAnimationStyle(R.style.AnimationPreview);        // 自定义view添加触摸事件        customView.setOnTouchListener(new OnTouchListener() {          @Override          public boolean onTouch(View v, MotionEvent event) {            if (popupWindow3 != null && popupWindow3.isShowing()) {              popupWindow3.dismiss();              popupWindow3 = null;            }            return false;          }        });      }    if(number==4) {      customView = getLayoutInflater().inflate(R.layout.popup_frame, null, false);        popupWindow4 = new PopupWindow(customView, 450, 150);      // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法         popupWindow4.setFocusable(true);        popupWindow4.setAnimationStyle(R.style.AnimationPreview);        // 自定义view添加触摸事件        customView.setOnTouchListener(new OnTouchListener() {          @Override          public boolean onTouch(View v, MotionEvent event) {            if (popupWindow4 != null && popupWindow4.isShowing()) {              popupWindow4.dismiss();              popupWindow4 = null;            }            return false;          }        });      }    if(number==5) {      customView = getLayoutInflater().inflate(R.layout.popup_frame, null, false);        popupWindow5 = new PopupWindow(customView, 450, 150);      // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法         popupWindow5.setFocusable(true);        popupWindow5.setAnimationStyle(R.style.AnimationPreview);        // 自定义view添加触摸事件        customView.setOnTouchListener(new OnTouchListener() {          @Override          public boolean onTouch(View v, MotionEvent event) {            if (popupWindow5 != null && popupWindow5.isShowing()) {              popupWindow5.dismiss();              popupWindow5 = null;            }            return false;          }        });      } //end if  }

    四. PopupWindow实现点击效果

   

做到这里,你就能实现点击底部菜单实现弹出PopupWindows效果,但显然是不足的.怎样通过点击弹出PopupWindow中的按钮实现做不同的事情呢?下面讲解,你只需要添加下面的代码即可实现"特效"效果.

   

代码如下,你可以自定义函数实现不同效果功能(结合前面几篇文章,我的美图秀秀基本完成)：

if(number==3) { //效果  customView = getLayoutInflater().inflate(R.layout.popup_effect, null, false);    popupWindow3 = new PopupWindow(customView, 450, 150);  // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法     popupWindow3.setFocusable(true);    // 设置允许在外点击消失     popupWindow3.setOutsideTouchable(true);   popupWindow3.setAnimationStyle(R.style.AnimationPreview);    // 自定义view添加触摸事件    customView.setOnTouchListener(new OnTouchListener() {      @Override      public boolean onTouch(View v, MotionEvent event) {        if (popupWindow3 != null && popupWindow3.isShowing()) {          popupWindow3.dismiss();          popupWindow3 = null;        }        return false;      }    });    //判断点击子菜单不同按钮实现不同功能  LinearLayout layoutEffect1 = (LinearLayout) customView.findViewById(R.id.layout_effect_hj);  layoutEffect1.setOnClickListener(new OnClickListener() {    @Override    public void onClick(View v) {      Toast.makeText(MainActivity.this, "效果-怀旧", Toast.LENGTH_SHORT).show();    }  });  LinearLayout layoutEffect2 = (LinearLayout) customView.findViewById(R.id.layout_effect_fd);  layoutEffect2.setOnClickListener(new OnClickListener() {    @Override    public void onClick(View v) {      Toast.makeText(MainActivity.this, "效果-浮雕", Toast.LENGTH_SHORT).show();    }  });  LinearLayout layoutEffect3 = (LinearLayout) customView.findViewById(R.id.layout_effect_gz);  layoutEffect3.setOnClickListener(new OnClickListener() {    @Override    public void onClick(View v) {      Toast.makeText(MainActivity.this, "效果-光照", Toast.LENGTH_SHORT).show();    }  });  LinearLayout layoutEffect4 = (LinearLayout) customView.findViewById(R.id.layout_effect_sm);  layoutEffect4.setOnClickListener(new OnClickListener() {    @Override    public void onClick(View v) {      Toast.makeText(MainActivity.this, "效果-素描", Toast.LENGTH_SHORT).show();      //打开图片      OpenImage();    }  });  LinearLayout layoutEffect5 = (LinearLayout) customView.findViewById(R.id.layout_effect);  layoutEffect5.setOnClickListener(new OnClickListener() {    @Override    public void onClick(View v) {      Toast.makeText(MainActivity.this, "效果-锐化", Toast.LENGTH_SHORT).show();    }  });}

    五. 总结

本文章主要讲述如何加载菜单栏在底部,同时讲述PopupWindows弹出事件,其实更好的布局方法是通过适配器,但是我才学Android,很多东西还不懂.所以它只是一篇初级文章,但完全能实现需要功能.

Android之用PopupWindow实现弹出菜单

   

最后希望文章对大家有所帮助,如果文章中有错误或不足之处见谅~
