由于用户在短时间内按下按钮太快而导致错误。以下是错误：

点击按钮后您是否正在调用网络服务？有几种选择：

1.添加一个进度对话框，在后台禁用任何东西。如果它是一个网络服务，这是最好的解决方案。

2.在您执行任何操作的时间段内禁用屏幕中的任何 UI 元素。

3. 产生一个新线程或一个异步任务。

您可以使用布尔变量来防止在每次单击按钮时运行您的代码：

boolean isClicked=true;
Button btn = (Button) findViewById(YourId);
btn.setonClickListener(listener);
public onClickListener listener = new View.OnclickListener{
      onclick(View v){
      if(isClicked==true)
      {
        isClicked=false;
        doWork();
        //DO YOUR WORK HERE...
      }
      else
      {
        // DO NOTHING...
      }
      }
}
 public void doWork(){
      /// YOUR CODE HERE...

         //USE AsyncTask ,Hanlder,handlerThread, or Thread for performing long running         task in background on button click
        isClicked=true;


     }
