底部划出菜单使用POPWindow

怎么实现底部动画划出一个菜单，使用POPWindows是个不错的选择

首先设置POPWindow   xml:

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <LinearLayout        android:id="@+id/pop_layout"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:background="@drawable/btn_style_alert_dialog_background"        android:gravity="center_horizontal"        android:orientation="horizontal" >        <Button            android:id="@+id/gongneng_button"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_marginLeft="10dp"            android:layout_weight="1"            android:background="@drawable/bt_background_dm"            android:text="功能检测" />        <Button            android:id="@+id/jiaocai_button"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_marginLeft="10dp"            android:layout_weight="1"            android:background="@drawable/bt_background_dm"            android:text="交采检测" />        <Button            android:id="@+id/canshu_button"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_marginLeft="10dp"            android:layout_weight="1"            android:background="@drawable/bt_background_dm"            android:text="参数设置" />        <Button            android:id="@+id/lishi_button"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_marginLeft="10dp"            android:layout_weight="1"            android:background="@drawable/bt_background_dm"            android:text="历史记录" />        <Button            android:id="@+id/shebei_button"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_marginLeft="10dp"            android:layout_weight="1"            android:background="@drawable/bt_background_dm"            android:text="关于设备" />        <Button            android:id="@+id/women_button"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_marginLeft="10dp"            android:layout_weight="1"            android:background="@drawable/bt_background_dm"            android:text="关于我们" />    </LinearLayout>    </RelativeLayout>

POP的工具类

package com.example.supertext.utils;import com.example.supertext.First;import com.example.supertext.R;import com.example.supertext.Second;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.graphics.Color;import android.graphics.drawable.ColorDrawable;import android.view.Gravity;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;public class SelectPopupWindow extends PopupWindow {private Button btn_gongneng, btn_jiaocai, btn_canshu, btn_lishi,btn_shebei, btn_women;private View menuView;public static SelectPopupWindow window;private static Activity cActivity;public SelectPopupWindow(Context context, OnClickListener itemsOnClick) {super(context);LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);menuView = inflater.inflate(R.layout.dialogmenu, null);init(itemsOnClick);SetWindows();}private void SetWindows() {// 设置SelectPicPopupWindow的Viewthis.setContentView(menuView);// 设置SelectPicPopupWindow弹出窗体的宽this.setWidth(LayoutParams.MATCH_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);//透明ColorDrawable dw = new ColorDrawable(Color.argb(0, 0, 0, 0));// 设置SelectPicPopupWindow弹出窗体的背景this.setBackgroundDrawable(dw);menuView.setOnTouchListener(new OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {int height = menuView.findViewById(R.id.pop_layout).getTop();int y = (int) event.getY();if (event.getAction() == MotionEvent.ACTION_UP) {if (y < height) {dismiss();}}return true;}});}public void init(OnClickListener itemsOnClick) {btn_gongneng = (Button) menuView.findViewById(R.id.gongneng_button);btn_jiaocai = (Button) menuView.findViewById(R.id.jiaocai_button);btn_canshu = (Button) menuView.findViewById(R.id.canshu_button);btn_lishi = (Button) menuView.findViewById(R.id.lishi_button);btn_shebei = (Button) menuView.findViewById(R.id.shebei_button);btn_women = (Button) menuView.findViewById(R.id.women_button);btn_gongneng.setOnClickListener(itemsOnClick);btn_jiaocai.setOnClickListener(itemsOnClick);btn_canshu.setOnClickListener(itemsOnClick);btn_lishi.setOnClickListener(itemsOnClick);btn_shebei.setOnClickListener(itemsOnClick);btn_women.setOnClickListener(itemsOnClick);}public static void showDialog(Activity context,int id) {cActivity=context;window = new SelectPopupWindow(context, itemsOnClick);window.showAtLocation(context.findViewById(id), Gravity.BOTTOM| Gravity.CENTER, 0, 0);}static OnClickListener itemsOnClick = new OnClickListener() {@Overridepublic void onClick(View view) {window.dismiss();switch (view.getId()) {case R.id.gongneng_button:Intent intent = new Intent(cActivity, First.class);cActivity.startActivity(intent);break;case R.id.jiaocai_button:Intent intent1 = new Intent(cActivity, Second.class);cActivity.startActivity(intent1);break;}}};}

首页的布局和第一个，第二个布局是一样的：

xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:gravity="center"    android:orientation="vertical"    tools:context=".MainActivity"     android:id="@+id/menu">    <TextView        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:gravity="center"        android:text="首页"        android:textColor="#0099ff"        android:textSize="22dp" />    <ImageView        android:id="@+id/main_id"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:onClick="showDialog"        android:src="@drawable/gengduo_dm" /></LinearLayout>

只需要在每个Activity中去调用显示POP就好了

package com.example.supertext;import com.example.supertext.utils.SelectPopupWindow;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Gravity;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.ImageView;public class MainActivity extends Activity {private ImageView img1;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);img1 = (ImageView) findViewById(R.id.main_id);img1.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {SelectPopupWindow.showDialog(MainActivity.this,R.id.menu);}});}}

这样一个简单的底部菜单就实现了。
