Question

我是android的新开发者。我在片段和通知方面遇到困难。这是我的一些代码。

test.java

public class test extends Fragment {
 \\some of codes here up.

@Override
public View onCreateView(LayoutInflater, ViewGroup container, Bundle savedIntancesState) {
View view = inflater.inflate(R.layout.test_fragment, container, false);
 Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    FragmentManager fragmentManager = getActivity().getSupportFragmentManager();

    PendingIntent resultPendingIntent = PendingIntent.getActivity(getActivity(), fragmentManager.beginTransaction().replace(R.id.flContent, NextFragment.newInstance("message", R.layout.content_row)).commit(), getActivity().getIntent(), PendingIntent.FLAG_UPDATE_CURRENT);

    Notification notification = new NotificationCompat.Builder(getActivity())
            .setContentTitle(title)
            .setContentText(message)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentIntent(resultPendingIntent)
            .setSound(soundUri)
            .addAction(R.mipmap.ic_launcher, "Call",resultPendingIntent).build();
    NotificationManager notificationManager = (NotificationManager) getActivity().getSystemService(NOTIFICATION_SERVICE);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(0,notification);

    return view;
 }

我希望首先显示测试片段并发出通知，但该代码的结果是始终显示NextFragment类。请告诉我哪里出错了。我感谢任何帮助。非常感谢你。

创建一个单独的类来设置警报，该类扩展了BroadcastReceiver并从Fragment中调用它。请参阅链接： -

夸大您的测试片段布局： -

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.test_fragment, container, false);
        //your code for notification
        return view;
    }
