自定义弹框一（PopupWindow实现）响应两种点击事件

来源：互联网发布：linux cp命令编辑：程序博客网时间：2024/05/17 04:00

自定义弹框通常可以使用自定义的popupwindow，自定义的activity，自定义的dialog来实现这里先用popupwindow来实现并且可以在弹框上实现点击事件或者在其所依附的activity上响应其实都是一样的但是如果点击弹框想在activity上处理事件这种就比较简单了避免了使用接口对接

第一种在弹框上响应点击事件

先准备资源文件

alert_dialo.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:gravity="center_horizontal"    android:orientation="vertical"    >    <LinearLayout        android:id="@+id/pop_layout"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:gravity="center_horizontal"        android:orientation="vertical"        android:layout_alignParentBottom="true"        android:background="@drawable/btn_style_alert_dialog_background"        >        <Button            android:id="@+id/btn_take_photo"            android:layout_marginTop="20dip"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:text="拍照"            android:background="@drawable/btn_style_alert_dialog_button"            android:textStyle="bold"            />        <Button            android:id="@+id/btn_pick_photo"            android:layout_marginTop="5dip"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:text="从相册选择"            android:background="@drawable/btn_style_alert_dialog_button"            android:textStyle="bold"            />        <Button            android:id="@+id/btn_cancel"            android:layout_marginLeft="20dip"            android:layout_marginRight="20dip"            android:layout_marginTop="15dip"            android:layout_marginBottom="15dip"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:text="取消"            android:background="@drawable/btn_style_alert_dialog_cancel"            android:textColor="#ffffff"            android:textStyle="bold"            />    </LinearLayout></RelativeLayout>

资源文件对应的类

package com.example.administrator.zidingyipupwindow;import android.app.Activity;import android.content.Context;import android.graphics.drawable.ColorDrawable;import android.view.LayoutInflater;import android.view.MotionEvent;import android.view.View;import android.view.View.OnClickListener;import android.view.View.OnTouchListener;import android.view.ViewGroup.LayoutParams;import android.widget.Button;import android.widget.PopupWindow;import android.widget.Toast;public class SelectPicPopupWindow extends PopupWindow {    private Button btn_take_photo, btn_pick_photo, btn_cancel;    private View mMenuView;    public SelectPicPopupWindow(final Activity context, OnClickListener itemsOnClick) {        super(context);        LayoutInflater inflater = (LayoutInflater) context                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);        mMenuView = inflater.inflate(R.layout.alert_dialog, null);        btn_take_photo = (Button) mMenuView.findViewById(R.id.btn_take_photo);        btn_pick_photo = (Button) mMenuView.findViewById(R.id.btn_pick_photo);        btn_cancel = (Button) mMenuView.findViewById(R.id.btn_cancel);        //取消按钮        btn_cancel.setOnClickListener(new OnClickListener() {            public void onClick(View v) {                //销毁弹出框                dismiss();            }        });        //设置按钮监听        btn_pick_photo.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                Toast.makeText(context, "挑选照片", Toast.LENGTH_SHORT).show();            }        });        btn_take_photo.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                Toast.makeText(context, "拍照", Toast.LENGTH_SHORT).show();            }        });        //设置SelectPicPopupWindow的View        this.setContentView(mMenuView);        //设置SelectPicPopupWindow弹出窗体的宽        this.setWidth(LayoutParams.FILL_PARENT);        //设置SelectPicPopupWindow弹出窗体的高        this.setHeight(LayoutParams.WRAP_CONTENT);        //设置SelectPicPopupWindow弹出窗体可点击        this.setFocusable(true);        //设置SelectPicPopupWindow弹出窗体动画效果        this.setAnimationStyle(R.style.AnimBottom);        //实例化一个ColorDrawable颜色为半透明        ColorDrawable dw = new ColorDrawable(0xb0000000);        //设置SelectPicPopupWindow弹出窗体的背景        this.setBackgroundDrawable(dw);        //mMenuView添加OnTouchListener监听判断获取触屏位置如果在选择框外面则销毁弹出框        mMenuView.setOnTouchListener(new OnTouchListener() {            public boolean onTouch(View v, MotionEvent event) {                int height = mMenuView.findViewById(R.id.pop_layout).getTop();                int y=(int) event.getY();                if(event.getAction()==MotionEvent.ACTION_UP){                    if(y<height){                        dismiss();                    }                }                return true;            }        });    }}

R.style.AnimBottom
<style name="AnimBottom" parent="android:Animation">    <item name="android:windowEnterAnimation">@anim/pop_enter_anim</item>    <item name="android:windowExitAnimation">@anim/pop_exit_anim</item></style>

@anim/pop_enter_anim

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <!--<translate-->        <!--android:duration="450"-->        <!--android:fromYDelta="100%p"-->        <!--android:toYDelta="0" />-->    <alpha        android:duration="200"        android:fromAlpha="0"        android:toAlpha="1.0" />    // %p指相对于父容器    <translate        android:fromYDelta="100%p"        android:duration="300"        /></set>

@anim/pop_exit_anim
<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <translate        android:duration="450"        android:toYDelta="100%p"/>    <!--<alpha-->        <!--android:duration="200"-->        <!--android:fromAlpha="1.0"-->        <!--android:toAlpha="0.0" />--></set

这里面 @anim/pop_exit_anim 和@anim/pop_exit_anim都是在新建的anim里
下面是mainactivity里的资源文件
activity_main.xml
   
<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:gravity="center_horizontal"    android:id="@+id/main"    android:orientation="vertical"    >    <TextView        android:id="@+id/text"        android:layout_width="50dip"        android:layout_height="30dip"        android:textSize="20sp"        android:text="点我"/></LinearLayout>

所对应的类 即是mainactivity里的东西
package com.example.administrator.zidingyipupwindow;import android.app.Activity;import android.os.Bundle;import android.view.Gravity;import android.view.View;import android.view.View.OnClickListener;import android.widget.TextView;public class MainActivity extends Activity {    //自定义的弹出框类      SelectPicPopupWindow menuWindow;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        TextView tv = (TextView) this.findViewById(R.id.text);        //把文字控件添加监听，点击弹出自定义窗口          tv.setOnClickListener(new OnClickListener() {            public void onClick(View v) {                //实例化SelectPicPopupWindow                  menuWindow = new SelectPicPopupWindow(MainActivity.this, itemsOnClick);                //显示窗口                  menuWindow.showAtLocation(MainActivity.this.findViewById(R.id.main), Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL, 0, 0); //设置layout在PopupWindow中显示的位置              }        });    }
}
以上是点击事件在弹框里处理  既是相应的挑选 拍照吐司 里
第二种 
第二种 方式 是点击事件在 activity中处理只需要在mainactivity中加上几句话  让其变为
package com.example.administrator.zidingyipupwindow;import android.app.Activity;import android.os.Bundle;import android.view.Gravity;import android.view.View;import android.view.View.OnClickListener;import android.widget.TextView;public class MainActivity extends Activity {    //自定义的弹出框类      SelectPicPopupWindow menuWindow;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        TextView tv = (TextView) this.findViewById(R.id.text);        //把文字控件添加监听，点击弹出自定义窗口          tv.setOnClickListener(new OnClickListener() {            public void onClick(View v) {                //实例化SelectPicPopupWindow                  menuWindow = new SelectPicPopupWindow(MainActivity.this, itemsOnClick);                //显示窗口                  menuWindow.showAtLocation(MainActivity.this.findViewById(R.id.main), Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL, 0, 0); //设置layout在PopupWindow中显示的位置              }        });    }    //为弹出窗口实现监听类      private OnClickListener  itemsOnClick = new OnClickListener(){        public void onClick(View v) {            menuWindow.dismiss();            switch (v.getId()) {                case R.id.btn_take_photo://                    Toast.makeText(MainActivity.this, "拍照---", Toast.LENGTH_SHORT).show();                    break;                case R.id.btn_pick_photo://                    Toast.makeText(MainActivity.this, "嘻嘻---", Toast.LENGTH_SHORT).show();                    break;                default:                    break;            }        }    };}  
  并且   在SelectPicPopupWindow中  把设置按钮监听去掉 就OK了
