我有一个Android项目，所有源代码都没有错误，但有时会给我一个力量关闭。
这是我的代码：
timecompletedialog.java
public class QuizActivity extends BaseFragmentActivity implements OnClickListener,AnswerListener,
OnTimeCompleteListener{
private TextView questionTextView,timer_text,score_text;
private ImageButton option_1, option_2, option_3, option_4;

if(timer>0){
//Time is running
timer--;
timer_text.setText("Time : "+timer);

}else{
timeComplete.onTimeFinish();
}
}
};

}

GameCompleteDialog dialog=new GameCompleteDialog(QuizActivity.this,SCORE_COUNTER);
dialog.buildDialog();
dialog.showDialog();
handler.removeCallbacks(timerThread);
}
public void onTimeFinish() {
TimeCompleteDialog dialog=new TimeCompleteDialog(this);
dialog.showDialog();
AnswerHandler.vibrate(this);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK))
{
finish();
}
return super.onKeyDown(keyCode, event);
}
}
在此代码中没有错误。但我不知道出了什么问题。

android.view.WindowManager $ BadTokenException：无法添加窗口 - 令牌android.os.BinderProxy@b2282c30无效;是你的活动 运行
当您在当前Activity上调用finish（）后尝试显示对话框时，通常会发生这种情况。在你的代码中，这发生了两次。在TimeCompleteDialog和onKeyDown中。可能会发生的事情是你在Activity上调用finish（），而忘记清理Runnable的队列。调用timeComplete.onTimeFinish();时，在这种情况下，您将遇到此类崩溃。如果我在你身边，我采取的第一个动作是在暂停活动时清理处理程序的队列。第二件事是在显示弹出窗口之前检查活动的isRunning标志。
E.g。
if (!isFinishing()) {
// show popup
}
答案 1 :(得分：1)
在我导航到另一个活动后（当该活动在后台时），通过强制代码显示一个对话框，我能够在我的应用程序中重现这一点。
修复是在显示对话框之前添加以下检查：
if (activity == null) {
return false;
} else {
return !activity.isDestroyed() && !activity.isFinishing();
}
答案 2 :(得分：0)
出现此问题是，传递的上下文/活动不是活动的上下文/活动。 您应该通过当前活动或上下文
