Question

我正在尝试做一个flipcard应用程序，其中有一个图像的gridview显示相同的图像，比如card_back。

单击每个图像时，它会翻转显示另一个图像，该图像对于gridview的每个项目都是不同的，例如card_front。

如果2张牌显示了他们的card_front图像，则1秒后自动翻转以显示card_back。

我想要做的是，在这1-2秒内，用户不应该能够点击任何其他项目。即使他点击，也不应该在那2秒内翻转卡片。如何我这样做。是否可以使用覆盖整个gridview的透明视图，并使其仅在2秒内可见。有人可以帮助我。

   gridview.setOnItemClickListener(new OnItemClickListener()
        {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id)
            {   
                 pos=position;

               findViewById(R.id.view1).setBackgroundColor(getResources().getColor(android.R.color.transparent));


                 switch(flippedCardCounter)
                 {

                 case 0:
                     flippedCardCounter++;    //increase counter
                     v1=v;
                     startFlipAnimation(imageView,v1);
                     break;
                 //flippedCardCounter = 1 -> one card flipped
                 case 1:
                     flippedCardCounter++;    //increase counter
                     v2=v;
                     startFlipAnimation(imageView,v2);
                     im1=((ViewHolder) v1.getTag()).img;
                     im2=((ViewHolder) v2.getTag()).img;

                      Handler handler = new Handler(); 
                      handler.postDelayed(new Runnable() { 
                           public void run() { 
                                startUnflipAnimation(im1,v1);
                            startUnflipAnimation(im2,v2);
                           } 
                      },1000); 
                      break;
                 //flippedCardCounter = 2 -> hide two flipped card, flip one card
                 case 2:
                     flippedCardCounter = 0;  
                     flippedCardCounter++;   //increase counter
                     startFlipAnimation(imageView,v);
                     v1=v2=v;
                     break;
            }
                 }

              });

您可以在任意位置设置isLock变量以禁用时钟。我希望我能伸出援助之手！
