我尝试使用此代码来防止在ImageView中多次单击,但这无济于事.

    Boolean isClicked = false;
    @Override
    public void onClick(View v)
    {
        if (v == imgClick && !isClicked)
        {
                      //lock the image
            isClicked = true;
            Log.d(TAG, "button click");

            try
            {
                //I try to do some thing and then release the image view
                Thread.sleep(2000);
            } catch (InterruptedException e)
            {
                e.printStackTrace();
            }
            isClicked = false;
        }

    }

在日志猫中,当我尽快单击ImageView 5次时,可以看到5行“按钮单击”.我可以看到log cat打印第一行,等待一会儿(2秒),然后打印下一行.我想当我单击ImageView时,触发的事件将按顺序移到队列中,不是吗？那么我该如何阻止呢？
我也尝试使用setEnable()或setClickable()代替isClicked变量,但是它也不起作用.

解决方法:

只需尝试此工作代码

    Boolean canClick = true; //make global variable
   Handler  myHandler = new Handler();

@Override
public void onClick(View v)
{
    if (canClick)
    {

       canClick= false;   //lock the image
       myHandler.postDelayed(mMyRunnable, 2000);

       //perform  your action here

    }

}

/* give some delay..*/
    private Runnable mMyRunnable = new Runnable()
    {
        @Override
        public void run()
        {   

         canClick = true;
         myHandler.removeMessages(0);
        }
     };


Instead of sleeping in 2 seconds, I use some task like doSomeThing() method (has accessed UI thread), and I don't know when it completed. So how can I try your way?

//我提到了这个androidlink.您可以更有效地处理线程,但是我希望下面的代码对您有用.
//您尝试这个

 Boolean canClick = true; //make global variable
public void onClick(View v) {
        if(canClick){

          new DownloadImageTask().execute();
        }
    }

        private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {


            protected Bitmap doInBackground(String... urls) {
                 Log.d("MSG","Clicked");
                 canClick =false;
                 //perform your long operation here

                return null;
             }

             protected void onPostExecute(Bitmap result) {
                 canClick =true;
             }
         }
