Question

我尝试在我的活动中添加对话框，但是徒劳无功，以下是我的代码。

    private void saveMissionFile() {
    final String defaultFilename = TextUtils.isEmpty(openedMissionFilename)
            ? FileStream.getWaypointFilename("waypoints")
            : openedMissionFilename;

    final SupportEditInputDialog dialog = SupportEditInputDialog.newInstance(MISSION_FILENAME_DIALOG_TAG,
            getString(R.string.label_enter_filename), defaultFilename, true);
 //       dialog.show(getSupportFragmentManager(), MISSION_FILENAME_DIALOG_TAG);

    dialog.show(MyFirstPlanFirstActivity.this.fragmentManager, MISSION_FILENAME_DIALOG_TAG);


}

在我实施应用程序后，我收到此错误而不是应用程序崩溃，我该怎么办？

android.view.WindowManager $ BadTokenException：无法添加窗口无效;你的活动在运行吗？
