待通知意图不起作用

Question

以下是我的代码块，在点击通知时应该打开NotificationActivity。但它不起作用。

private void setNotification(String notificationMessage) {
    Uri alarmSound = getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    mNotificationManager  = getApplication().getSystemService(Context.NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(getApplicationContext(), NotificationActivity2.class);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext())
    .setSmallIcon(R.drawable.logo)
    .setContentTitle("My Notification")
    .setStyle(new NotificationCompat.BigTextStyle()
    .bigText(notificationMessage))
    .setContentText(notificationMessage).setAutoCancel(true);
    mBuilder.setSound(alarmSound);
    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

}

Answer 1

试试这个：

private void setNotification(String notificationMessage) {

//**add this line**
int requestID = (int) System.currentTimeMillis();

Uri alarmSound = getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
mNotificationManager  = getApplication().getSystemService(Context.NOTIFICATION_SERVICE);

Intent notificationIntent = new Intent(getApplicationContext(), NotificationActivity2.class);

//**add this line**
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); 

//**edit this line to put requestID as requestCode**
PendingIntent contentIntent = PendingIntent.getActivity(this, requestID,notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext())
.setSmallIcon(R.drawable.logo)
.setContentTitle("My Notification")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(notificationMessage))
.setContentText(notificationMessage).setAutoCancel(true);
mBuilder.setSound(alarmSound);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

}

Answer 2

您可能正在使用等于0的通知ID。已知通知ID为0的问题。如果您将使用任何其他ID，它应该有效。

Answer 3

我添加了任务构建器，下面的块代码为我工作

Intent intent = new Intent(context, HomeActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(SplashActivity.class);
stackBuilder.addNextIntent(intent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

Answer 4

如果该应用已在运行，则需要在onNewIntent

中进行处理

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);

    //Handle intent here...
}

Answer 5

添加了请求ID，但意图仍未打开。

这是对我有用的解决方案：

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

设置这些标志以清除意图活动下方的活动。

Answer 6

尝试检查您的AndroidManifest.xml，再次检查是否要导航到带有intent-filter main action, launcher category的活动

例如，

我无法让我的pending intent导航到HomeActivity，但是在导航到SplashScreen时可以使用

希望这会有所帮助。
