Android PopupWindow实现左侧弹窗效果

本文实例为大家分享了Android PopupWindow实现左侧弹窗的具体代码，供大家参考，具体内容如下

效果图：

MainActivity.java页面核心代码：

protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);
  //在setContentView之前添加,未添加的话home键监听无效，设置窗体属性
  this.getWindow().setFlags(0x80000000, 0x80000000);
  setContentView(R.layout.activity_main);

  //创建广播
  //InnerRecevier innerReceiver = new InnerRecevier();
  //动态注册广播
  //IntentFilter intentFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
  //启动广播
  //registerReceiver(innerReceiver, intentFilter);

  //外部网页
  // init();

  //pop
  Button pop = (Button) findViewById(R.id.popButton);
  pop.setOnClickListener(popClick);
 }
 View.OnClickListener popClick = new View.OnClickListener() {
  @Override
  public void onClick(View v) {
   getPopupWindow();
   popupWindow.showAtLocation(v, Gravity.LEFT,0,0);
  }
 };
 /*创建PopupWindow*/
 protected void initPopupWindow(){
  //获取自定义布局文件activity_pop_left.xml 布局文件
  final View popipWindow_view = getLayoutInflater().inflate(R.layout.activity_pop_left,null,false);
  //创建Popupwindow 实例，200，LayoutParams.MATCH_PARENT 分别是宽高
  popupWindow = new PopupWindow(popipWindow_view,300, ViewGroup.LayoutParams.MATCH_PARENT,true);
//设置动画效果
  popupWindow.setAnimationStyle(R.style.AnimationFade);
  //点击其他地方消失
  popipWindow_view.setOnTouchListener(new View.OnTouchListener() {
   @Override
   public boolean onTouch(View v, MotionEvent event) {
    if (popipWindow_view != null && popipWindow_view.isShown()) {
     popupWindow.dismiss();
     popupWindow = null;
    }
    return false;
   }
  });
  popupWindow.setBackgroundDrawable(new ColorDrawable(0));
  Button button1 = (Button) popipWindow_view.findViewById(R.id.button1);
  button1.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
    Toast.makeText(getApplicationContext(),"全屏显示",Toast.LENGTH_SHORT).show();
   }
  });
 }
/*获取PopipWinsow实例*/

private void getPopupWindow(){
 if (null!=popupWindow){

  popupWindow.dismiss();
  return;
 }else {
  initPopupWindow();
 }
}

activity_main.xml页面

<FrameLayout 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.x.MainActivity"
 tools:ignore="MergeRootFrame" >

 <WebView
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:id="@+id/webView"
 />
 <Button
  android:id="@+id/popButton"
  android:text="点击弹出左菜单" android:layout_width="fill_parent"
  android:layout_height="wrap_content" />
</FrameLayout>

左侧菜单需单独设置一个xml页面，style样式自定义。
