title: WindowManager with Animation (is it possible?)
body: <p>Is there any way to inflate a view with WindowManager using Animation (at android's project)? I just can't do it even using the examples in sites! I used many examples but none worked!</p>
  
  <pre><code>public BannerLayout(Activity activity, final Context context) {
      super(context);
  
      this.context = context;
  
      final WindowManager.LayoutParams params = new WindowManager.LayoutParams( 
              WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
              WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | 
              WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
              PixelFormat.TRANSLUCENT); 
  
      wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);    
  
      LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      this.popupLayout = (RelativeLayout) inflater.inflate(R.layout.popup_activity, null);
      this.popupLayout.setVisibility(GONE);
      this.setActive(false);
  
      wm.addView(this.popupLayout, params);
  
      context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  }
  
  
  private void show(){
      Animation in = AnimationUtils.loadAnimation(this.context, android.R.anim.fade_in);
      this.popupLayout.setAnimation(in);
  
      this.setActive(true);
      this.popupLayout.setVisibility(VISIBLE);
  }
  </code></pre>
