java - 待定 Intent 不是打开 Activity

Question

我是 Android 开发新手。我可以看到股票消息“您到达办公室了吗”，但是当我单击它时，它并没有打开我的主要 Activity 。

下面是我的代码:

private class ViewUpdater implements Runnable{
  private Context contextFromView;
  public ViewUpdater(Context context) {
    this.contextFromView = context;
  }
  @Override
  public void run() {
    CancelNotification(contextFromView, notificationId);
    Random r=  new Random();
    notificationId =r.nextInt();
    Intent intent = new Intent();
    FragmentActivity activity = getActivity();
    PendingIntent pi = PendingIntent.getActivity(getActivity(),1000,intent,0);
    String body = "congratulations you made it today";
    String title = "Office reached";
    NotificationCompat.Builder mBuilder =
      new NotificationCompat.Builder(getActivity())
      .setSmallIcon(R.drawable.abc_ic_go)
      .setContentTitle(title)
      .setTicker("Did you reach office?")
      .setContentText(body);
    mBuilder.setContentIntent(pi);
    nm.notify(notificationId, mBuilder.build());
    timerHandler.postDelayed(this, 200000);
  }
}

在创建 PendingIntent 时，您必须给出一个 Intent 来启动正确的 Activity。此外，FLAG_ACTIVITY_NEW_TASK 也是必需的，因为您将在现有 Activity 的上下文之外启动该 Activity(来源:Android doc)。

Intent = new Intent(getActivity(), YourActivity.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pi = PendingIntent.getActivity(getActivity(),1000,intent,0);
