不止一次按下按钮

当按钮被按下不止一次时，我正在关闭力量。我有一个条件，如果互联网连接，然后谷歌地图将显示。如果互联网没有连接，那么我已经保持一个警告框显示检查我们的互联网连接。所以问题在这里。如果按下按钮时互联网未连接，则显示警报框。但如果多次点击，它会显示FORCE CLOSE。我已经把在catch块alertbox显示..不止一次按下按钮

case R.id.geocode_button: // Place name as selected by the user. 

      placeName = placeText.getText().toString(); 
      clik=1;   
      placenametemp = placeName; 
      System.out.println(""+placenametemp); 

      String [] optionArray = new String[numberOptions]; 
      Geocoder gcoder = new Geocoder(this); 

      try 
      { 
           ///// code to display google map 


      } 
      catch (IOException e) 
      { 
      if(!dialogShown) 
       { 
        dialogShown = true; 
        //Show your dialog 

       new 
     AlertDialog.Builder(this).setIcon(R.drawable.icon).setTitle(
       " Check your Internet 
     Connection!").setPositiveButton("OK", 
       new DialogInterface.OnClickListener() 
       { 

        @Override 
        public void onClick(DialogInterface dialog, 
        int which) 
        { 
         dialogShown = false;  
         // TODO Auto-generated method stub 
         dialog.cancel(); 
        } 
       }).show(); 

       Log.e("Geocoder", "I/O Failure; is network  
                   available?",e); 
      } 
          }

您不能显示的警告对话框中一个以上的时间，所以把像检查这

首先创建一个类级别变量

public boolean dialogShown = false;

然后在这里case R.id.geocode_button

if(!dialogShown){ 
dialogShown = true; 
//Show your dialog 
}

然后在对话框ok按钮单击listener

dialogShown = false;

更新

检查您的网络连接像这样的离子

void boolean checkInternet(){ 
    NetworkInfo i = conMgr.getActiveNetworkInfo(); 
    if (i == null) 
    return false; 
    if (!i.isConnected()) 
    return false; 
    if (!i.isAvailable()) 
    return false; 
    return true; 
}

我已更新我的catch块..Sir我猜问题不是因为警报框因为刚刚尝试过与Toast味精同样的情况，并且当按钮被按下很多次时，我仍然收到了强制关闭 – Sindu

对。首先，这不是检查互联网连接是否可用的方法。但这不是问题。 第一个问题是CalledFromTheWrongThread异常，这意味着某个地方你试图从另一个线程访问UI元素。永远不要这样做。我猜你有一个AsyncTask尝试以不允许的方式发布一些更新。 （在com.journey.snoozer.ShowTheMap.mapProgress（ShowTheMap.java:143））

这里的主要问题是WindowLeaked异常向下几行。例如，当你退出一个活动并尝试访问一个对话框时，会发生这种情况。 （方向更改等）由于您有涉及AsyncTask的其他异常，我想知道是否在发生IO异常时取消第一个AsycTask。

因此，请确保在onPause（）中的AsyncTask上使用.cancel（），并在任务创建的对话框上使用dissmiss（）。
