  <pre><code>    @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.fragment_main);
      pushView = LayoutInflater.from(getApplicationContext()).inflate(
              R.layout.push, null);
  
      btn = (Button) findViewById(R.id.btn);
      cancelBtn = (Button) pushView.findViewById(R.id.cancelBtn);
      windowManager = getWindowManager();
      handler = new MyHandler();
  
      pushView.setOnClickListener(new OnClickListener() {
  
          @Override
          public void onClick(View arg0) {
              System.out.println("onclick");
              windowManager.removeView(pushView);
          }
      });
  
  
      btn.setOnClickListener(new OnClickListener() {
  
          @Override
          public void onClick(View arg0) {
              WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                      WindowManager.LayoutParams.MATCH_PARENT, 
                      WindowManager.LayoutParams.WRAP_CONTENT,

              params.gravity = Gravity.TOP | Gravity.LEFT;
              params.y = 0;
              params.x = 0;
  
              windowManager.addView(pushView, params);
  
              new Timer().schedule(new TimerTask() {
  
                  @Override
                  public void run() {
                      Message msg = handler.obtainMessage();
                      handler.sendEmptyMessage(0x123);
                  }
