当多次按下按钮时，我会强制关闭。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，那么我保持一个警报框显示检查我们的互联网连接。所以问题出在这里。如果按下按钮时未连接互联网，则会显示警告框。但如果不止一次点击它会显示FORCE CLOSE。我已将警报框显示放在catch块中..

答案 0 :(得分：0)
您不能多次显示警告对话框，因此请执行此类检查
首先创建一个类级变量
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按钮中点击listener
dialogShown = false;
<强>更新
检查您的网络连接
void boolean checkInternet(){
NetworkInfo i = conMgr.getActiveNetworkInfo();
if (i == null)
return false;
if (!i.isConnected())
return false;
if (!i.isAvailable())
return false;
return true;
}
答案 1 :(得分：0)
右。首先，这不是检查互联网连接是否可用的方法。但这不是问题所在。 第一个问题是CalledFromTheWrongThread异常，这意味着你正试图从另一个线程访问UI元素。不要那样做。我猜你有一个AsyncTask试图以一种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异常几行。例如，当您退出某个活动然后尝试访问Dialog时，就会发生这种情况。 （方向更改等）由于您遇到了涉及AsyncTask的另一个异常，我想知道是否在IO异常发生时取消了第一个AsycTask。
因此，请确保在onPause（）上的AsyncTask中使用.cancel（），并在任务创建的对话框上使用dissmiss（）。
