       Animation fadeOut = new AlphaAnimation(1, 0); 
       fadeOut.setFillAfter(true); 
       fadeOut.setDuration(250); 
       paPreviewView.startAnimation(fadeOut); 
       this.paIsPreviewShowed = false; 

       ((RelativeLayout) paPreviewView.getParent()).removeView(paPreviewView); 
      } 

       } 


    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.activity_main, menu); 
     return true; 
    } 
}

好了，所以，在第一步驟之後創建的Activiti我OnClickListener設置到ImageView的paPreviewView的每一張牌（pic_a1，pic_a2 ... pic_e5）和可見性，以無形的（這裏我想選擇卡的顯示圖像）。然後，當我點擊pic_a1 paPreviewView顯示。還行吧。我的問題是。

1）在我這個例子中，我躲在paPreviewView ImageView的早期版本通過調用

paPreviewView.setVisibility(View.INVISIBLE);

或

paPreviewView.setVisibility(View.GONE);

，但它並沒有正常工作。因爲方法OnClickListener.onClick只能從隱藏的paPreviewView ImageView中調用。所以我試圖從paPreviewView中刪除OnClickListener，但它沒有幫助。只有工作解決方案是刪除（用於隱藏）並添加（用於顯示）從/到mainPanel的paPreviewView。

我的問題是爲什麼？爲什麼paPreviewView在隱藏paPreviewView時引發onClick事件？

2）而我的第二個問題是。比我爲這個例子（我的意思是紙牌遊戲）更好的解決方案？

非常感謝任何想法:)

ImageView.setVisibility（）只改變視圖的「可視性」，它仍然註冊到監聽。

可以使用

paPreviewView.setEnabled(false);

不接收單擊事件。

感謝這有助於:) – Droid

在這種情況下，使用正確的函數是：

paPreviewView.setClickable(false);
