通知点击的Android调用方法

Question

此代码创建一个通知。如果点击它，则运行当前应用程序（intent 是在Entry 中创建的，这是我唯一的Activity），一个Android 开发者博客的略微修改版本：

private void makeIntent() {
    NotificationManager mgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    Notification note = new Notification(R.drawable.prev, "Status message!", System.currentTimeMillis());
    Intent intent = new Intent(this, Entry.class);
    PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);
    note.setLatestEventInfo(this, "New Email", "Unread Conversation", pi);
    note.flags |= Notification.FLAG_AUTO_CANCEL;
    mgr.notify(NOTIFY_ME_ID, note);
}

但我不想启动任何活动，而只想在当前活动中运行一个方法。根据我目前所读到的内容，我想我必须使用startActivityForResult() 之类的方法，使用intent-filters 并实现onActivityResult()，但是在搞砸了所有这些事情之后，在Intent 和@987654328 中进行更改@，我仍然没有可用的结果。是否有可能以某种方式调用Entry 中的一个方法（我的主要Activity，其中创建了Intent），或者当我单击我新创建的Notification 时捕获任何传出或传入的Intents？

PS。如果这是一个重复的线程，我很抱歉，所以现在很慢，我无法正确搜索。

在清单文件中的activity 中添加android:launchMode="singleTop"，使用protected void onNewIntent(Intent intent) { ... } 方法并使用以下代码：

private static final int MY_NOTIFICATION_ID = 1;
private NotificationManager notificationManager;
private Notification myNotification;

void notification() {   
    notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    myNotification = new Notification(R.drawable.next, "Notification!", System.currentTimeMillis());
    Context context = getApplicationContext();
    String notificationTitle = "Exercise of Notification!";
    String notificationText = "http://android-er.blogspot.com/";
    Intent myIntent = new Intent(this, YourActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(YourActivity.this, 0, myIntent, Intent.FILL_IN_ACTION);
    myNotification.flags |= Notification.FLAG_AUTO_CANCEL;
    myNotification.setLatestEventInfo(context, notificationTitle, notificationText, pendingIntent);
    notificationManager.notify(MY_NOTIFICATION_ID, myNotification);
}

这对我来说 100% 有效：

将此代码放在方法中：

Intent intent = new Intent(this, YourClass.class);
    intent.putExtra("NotiClick",true);
    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

 if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
        Notification Noti;
        Noti = new Notification.Builder(this)
                .setContentTitle("YourTitle")
                .setContentText("YourDescription")
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(pIntent)
                .setAutoCancel(true).build();

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        notificationManager.notify(0, Noti);
    }

然后在你的类的 onCreate/constructor 中这样做：

if (savedInstanceState == null) {
        Bundle extras = getIntent().getExtras();
        if(extras == null) 
        {
            //Cry about not being clicked on
        } 
        else if (extras.getBoolean("NotiClick"))
        {
            //Do your stuff here mate :)
        }

    }

    Intent intent = new Intent(this, Notificationintent.class);
    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);



    Notification noti = new Notification.Builder(this)
    .setContentTitle("APP NOTIFICATION")
    .setContentText(messageValue)
    .setSmallIcon(R.drawable.ic_launcher)
     .setStyle(new Notification.BigTextStyle()
     .bigText(messageValue))
    .setContentIntent(pIntent).build();

NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// hide the notification after its selected
noti.flags |= Notification.FLAG_AUTO_CANCEL;

notificationManager.notify(0, noti);
