android.view.WindowManager $ BadTokenException：无法添加窗口 -

我们正在运行一个长时间运行的应用程序（运行时间超过5小时）来跟踪通过GPS的路径。随着时间的推移，我们不会增加任何数据。使用一些全局变量来保持距离和时间。但是，当我们试图显示对话框时，有一段时间我们正在崩溃，但很难重现。这是堆栈跟踪

我看到了这些帖子

和许多其他的解决方案的每一个告诉检查activity.isFinishing（），甚至我没有使用getApplicationContext（）来显示对话框。当我们没有叫完（）。很奇怪，这是幸福。请让我知道你的想法。

用于显示对话框这是按键的点击

Java代码：

HandleEndTrip（）方法被称为按钮

的点击对于所有eventhandeler有关的活动我创建了一个Java类

public class SavariMapActivityEventHandler extends EventHandler { 
    private static SavariMapActivityEventHandler instance = null; 

    @Override 
    public void handleClick(Activity activity) { 
     setActivity(activity); 
     INITClick(); 
    } 

    @Override 
    public void INITClick() { 
     getActivity().findViewById(R.id.endtrip).setOnClickListener(this); 
     getActivity().findViewById(R.id.expensebutton).setOnClickListener(this); 
     getActivity().findViewById(R.id.details).setOnClickListener(this); 

    } 

    private SavariMapActivityEventHandler() { 


    } 

    @Override 
    public void onClick(View v) { 
     switch (v.getId()) { 
     case R.id.endtrip: 
      HandleEndTrip(); 
       break; 

     } 
    } 

    private void HandleEndTrip() { 
     AlertDialog alertDialog = new Builder(getActivity()).create(); 
     alertDialog.setTitle("Confirmation"); 
     alertDialog.setMessage("Has the trip ended?"); 
     alertDialog.setButton2("Cancel", new DialogInterface.OnClickListener() { 
      @Override 
      public void onClick(DialogInterface arg0, int arg1) { 
       arg0.dismiss(); 
      } 
     }); 
     alertDialog.setButton("Yes", new DialogInterface.OnClickListener() { 
      @Override 
      public void onClick(DialogInterface arg0, int arg1) { 
       try { 
        getActivity().endthread = true; 
        getActivity().getHandler().removeCallbacksAndMessages(null); 
        TimeCalculator calculator = new TimeCalculator(
          getActivity(), System.currentTimeMillis(), holder 
            .getStartfromGarageTime()); 
        CustomerInfo.getInstance().setEndduration(
          calculator.getHour()); 
        getActivity().finish(); 
        SavariMapActivityEventHandler.getInstance() 
          .finishActivity(); 
        getActivity().startActivity(
          new Intent(getActivity(), 
            BillingConfirmActivity.class)); 

       } 
       catch (Exception e) 
       { 
        SavariUserSettings.appendLog("Savaari MapAcivityEventHandeler", ""+e+" "+e.getStackTrace()[0].getLineNumber());     
       } 
      } 
     }); 

     alertDialog.show(); 

    } 

    @Override 
    public SavariMapActivity getActivity() { 
     return (SavariMapActivity) super.getActivity(); 
    } 

    public static SavariMapActivityEventHandler getInstance() 
    { 
     if (instance == null) 
      instance = new SavariMapActivityEventHandler(); 
     return instance; 
    } 

    public static void setInstance(SavariMapActivityEventHandler instance) { 
     SavariMapActivityEventHandler.instance = instance; 
    } 
}

代码事件处理程序：

public abstract class EventHandler implements OnClickListener { 
private ProgressDialog dialog; 
public final String SETTINGS_PREFERENCE = "setting_pref"; 
private Activity activity; 

public abstract void handleClick(Activity activity); 

public abstract void INITClick(); 

public ValueHolder holder = null; 

protected final void setActivity(Activity activity) { 
    this.activity = activity; 
    holder = new ValueHolder(activity); 

} 

public final void finishActivity() { 
    activity.finish(); 
} 

public final void INITDialog(String title, String mesg) { 
    dialog = new ProgressDialog(activity); 
    dialog.setTitle(title); 
    dialog.setMessage(mesg); 
    dialog.show(); 
} 

public final void finishDialog() { 
    try { 
     if (dialog != null) 
      dialog.dismiss(); 
     } catch (Exception e) 
     { 

     } 
} 

public Activity getActivity() { 
    return activity; 
}

}

也许你从错误的地方叫getApplicationContext（）请您检查或还张贴在这里您的Java代码精确解。 – 2013-04-27 12:37:30

嘿，请检查[这个答案]（http://stackoverflow.com/questions/10429213/windowmanagerbadtokenexception-in-android/10429486#10429486）。这是你用对话面临的同样的问题，并且已经解决了。 – 2013-04-27 12:45:24

启动警报对话框前检查，如果活动结束

if(!isFinishing()){ 
    // create and show dialog 
}
