Android：移動imageView即位於窗口管理器與動畫

Question

有一些問題，並沒有找到解決辦法。問題是，我有一個佈局圖像視圖，這個佈局放在窗口管理器上，這個圖像視圖是可點擊的。此圖片視圖必須移動到正確的位置並且可以點擊。這裏是我的代碼

private WindowManager windowManager; 

private ImageView floatingUnit; 

private boolean isClicked; 

public void onCreate() { 

    super.onCreate(); 

    isClicked = false; 

    floatingUnit = new ImageView(this); 
    //a unit as imageView 
    Picasso.with(this).load(new File(Environment.getExternalStorageDirectory().getPath() +"/" + "cat.png")).into(floatingUnit); 

    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(AppMethods.getPxFromDp(120 ,this), AppMethods.getPxFromDp(120 , this));

    final LinearLayout floatingUnitLayout = new LinearLayout(this); 

    floatingUnitLayout.addView(floatingUnit); 

    windowManager = (WindowManager) this.getSystemService(WINDOW_SERVICE); 
    //here is all the science of params

    // add a floatingUnit icon in window

} 

` 請幫助。謝謝 ！

謝謝大家。自己找到解決方案。訣竅是：要移動窗口管理器上的圖像，必須更新佈局參數。

這裏是低於

private void startAnimationTimer(final View floatingUnitLayout) { 

    long animationLifeTime = AppData.first(AppData.class).getCountSecondsPicShow(); 
    countDownTimer = new CountDownTimer(animationLifeTime, 100) { 

     public void onTick(long millisUntilFinished) { 

      Log.i("animation remaining: ", Long.toString(millisUntilFinished/1000)); 
      myParams.x = myParams.x + 2; 
      myParams.y = myParams.y + 2; 
      windowManager.updateViewLayout(floatingUnitLayout, myParams); 


     } 

     public void onFinish() { 
      Log.i("animation: ", "DONE"); 
      if (!isClicked) { 

       windowManager.removeViewImmediate(floatingUnitLayout); 
       stopSelf(); 
      } 
     } 
    }.start(); 


}
