Question

我想通过BroadcastReceiver发送通知。 AlarmReceiver发送的通知，但是当我点击通知时再次发送通知。同样的事情再次发生，一次又一次地像无尽的循环

这是我的AlarmReceiver.java

public class AlarmReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

    android.support.v7.app.NotificationCompat.Builder builder = new android.support.v7.app.NotificationCompat.Builder(context);

    builder.setSmallIcon(R.mipmap.ic_launcher);

    // This intent is fired when notification is clicked
    Intent i = new Intent(context, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, i, 0);

    // Notifcation notify sound
    Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    // Set the intent that will fire when the user taps the notification.
    builder.setContentIntent(pendingIntent);

    // Large icon appears on the left of the notification
    builder.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher));

    // Content title, which appears in large type at the top of the notification
    builder.setContentTitle("Have a good weekend");

    //Notification click after clear notification
    builder.setAutoCancel(true);

    //Set notification sound
    builder.setSound(alarmSound);

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    // Will display the notification in the notification bar
    notificationManager.notify(1, builder.build());

    }
}

和MainActivity.java

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    setAlarm();
}

private void setAlarm(){
    AlarmManager manager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    Intent alarmIntent = new Intent(MainActivity.this, MyAlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, alarmIntent, 0);

    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());

    calendar.set(Calendar.DAY_OF_WEEK,6);
    calendar.set(Calendar.HOUR_OF_DAY,16);
    calendar.set(Calendar.MINUTE,53);
    calendar.set(Calendar.SECOND,0);

    manager.setInexactRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pendingIntent);

    }
}

点击通知时，它会打开MainActivity，并在此活动的onCreate方法中调用setAlarm()。因此，在单击通知onCreate方法时，将调用setAlarm()，然后再次设置警报和构建通知。

执行以下更改

调用按钮的setAlarm() onClick，以便不会自动调用onCreate个活动。

如果您想自动发送通知

更改notification

的意图

 Intent i = new Intent(context, MainActivity.class);

截至目前，您正在使用意图点击通知打开ManinActivity。

将Intent更改为

 Intent i = new Intent(context, OtherActivity.class);

OtherActivity是setAlarm()方法中没有notification或构建onCreate的活动。

替代方法

使用sharedPreferences检查通知是否构建一次。如果构建一次则不要调用setAlarm()

如何在单击通知时避免连续通知
