获取WindowManager $ BadTokenException：无法添加窗口

时间：2015-11-24 12:15:28

标签： android fragment android-tabhost

我已使用Tab主机停止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，我试图在单击特定视图时显示日期/时间选择器。但是应用程序因以下错误而崩溃。

我正在使用CiTux datetime picker。

我尝试过不使用标签主机的演示应用，效果很好。但是在我的应用中使用标签时它不起作用。请帮助解决任何问题..

答案 0 :(得分：0)

最后我得到了答案。这就是getFragmentManager（），我们在对话框的show（）方法中传递它。我们需要从TabHost Activity创建getFragmentManager（），因为对话框尝试从中获取上下文。所以它找不到合适的上下文对象。

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();

}
