获取WindowManager $ BadTokenException：无法添加窗口

我已经使用Tab主机切换了选项卡式应用程序。有5个选项卡，第一个选项卡包含一个片段。在该片段中，我试图在点击特定视图时显示日期/时间选择器。但该应用程序崩溃与以下错误。我正在使用CiTux datetime picker。

我试过了一个演示应用程序，没有使用标签主机，它的工作原理很棒。但在我的应用程序中使用选项卡时它不起作用。如果有任何解决方案，帮助..

AJApplication的用途是什么？您的启动器活动是什么？ – Radhey

@Jigs AjApplication是应用程序类，SplashScreen.java是启动器活动。 –

它是否在使用Intent启动新活动时在EntryTabActivity类中引发错误？ – Radhey

最后我得到了答案。这是getFragmentManager（），我们在show（）方法中传入对话框。我们需要在TabHost Activity中创建getFragmentManager（），因为对话框试图从它获取上下文。所以它没有找到正确的上下文对象。

DatePickerDialog.newInstance(
       MainActivity.tabContext, 
       dateNow.get(Calendar.YEAR), 
       dateNow.get(Calendar.MONTH), 
       dateNow.get(Calendar.DAY_OF_MONTH) 
     ); 

     dpd.show(MainActivity.tabContext.getFragmentManager(), "Datepickerdialog");

声明一个你的TabHost活动的静态实例并完成工作。快乐的编码。

public class MainActivity extends TabActivity implements TimePickerDialog.OnTimeSetListener,DatePickerDialog.OnDateSetListener{ 
private static final String TAG=MainActivity.class.getSimpleName(); 
AJApplication application; 

TabHost tabHost; 
public static MainActivity tabContext; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    Log.i(TAG, "onCreate()"); 
    setContentView(R.layout.activity_main); 
    application=AJApplication.getInstance(); 
    tabContext=this; 
    tabHost=getTabHost(); 

}
