塊訪問GridView

Question

我有一個小記憶遊戲，你可以點擊連續2張圖片。圖像顯示在GridView中。點擊2次後，我會比較這些翻轉的圖像。如果它們不一樣，該代碼就會被執行：

   else{ 
        // new try 
        Handler mHandler = new Handler(); 
        mHandler.postDelayed(update, 2000); 
       } 
       clickCounter = -1; 
       } 
} 

private Runnable update = new Runnable() { 
     public void run() { 

     viewHolder[0].setImageResource(R.drawable.card_back); 
     viewHolder[1].setImageResource(R.drawable.card_back); 
     } 
    }; 

，使用戶可以看到點擊的圖片2秒鐘，然後他們就會切換回卡的背面。但是我怎樣才能在這兩秒內阻止GridView/ImageView上的用戶操作。否則，在兩秒鐘內可以發現任何數量的圖像而無需進行比較。

我嘗試這樣的東西：

gridview.setClickable(false); 

或

gridview.setEnabled(false); 

但我總是得到一個錯誤。我會很感激的幫助。

您可以嘗試在堆棧中使用switchImage一些布爾或任何更高。事情是這樣的：

private boolean interactionEnabled = true; // code added 
public void switchImage(int position, View view){ 
    if (!interactionEnabled) return; // code added 
    //... your code here 

    else{ 
     interactionEnabled = false; // code added 
     Handler mHandler = new Handler(); 
     mHandler.postDelayed(update, 2000); 
    }     
} 

private Runnable update = new Runnable() { 
    public void run() { 
     viewHolder[0].setImageResource(R.drawable.card_back); 
     viewHolder[1].setImageResource(R.drawable.card_back); 
     interactionEnabled = true; // code added 
    } 
};
