android – 在推送通知上振动

首先,我检查了所有这些链接：

> Android notifications and vibrate from service
> Android GCM turn on Lights

但是当我收到推送通知时,我无法实现手机振动.这是我的代码：

PushReceiver

public class PushReceiver extends FirebaseMessagingService {
    public PushReceiver() {
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        if(remoteMessage.getData() != null){
            Map<String,String> data = remoteMessage.getData();
            sendNotification(data.get("message"));
        }
        else{
            if(remoteMessage.getNotification() != null) {
                sendNotification(remoteMessage.getNotification().getBody());
            }
        }
    }

    private void sendNotification(String messageBody) {
        Intent intent = new Intent(this,BaseActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this,0 /* Request code */,intent,PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri = ringtoneManager.getDefaultUri(ringtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_done_all_24dp)
                .setContentTitle(getString(R.string.str_notification_order_ready))
                .setContentText(messageBody)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        notificationBuilder.setVibrate(new long[] { 1000,1000,1000 });

        notificationmanager notificationmanager =
                (notificationmanager) getSystemService(Context.NOTIFICATION_SERVICE);


        notificationmanager.notify(ConstantUtils.NOTIFICATION_ID_ORDER_READY,notificationBuilder.build());
    }
}

允许

<uses-permission android:name="android.permission.VIBRATE"/>

测试

Device: Nexus 5

Android version: 6.0.1

为了让它发挥作用,我应该做些什么样的未知巫术？

解决方法

您还可以将setDefaults(int defaults)用于NotificationCompat.Builder实例,该实例为您的通知提供默认的系统声音,振动和灯光.

该值应为以下一个或多个字段与按位或(|)：DEFAULT_SOUND,DEFAULT_VIBRATE,DEFAULT_LIGHTS组合.

对于所有默认值,请使用DEFAULT_ALL.

防爆.根据你的代码,你设置默认声音,如果你想设置默认声音和振动：

notificationBuilder.setDefaults(DEFAULT_SOUND | DEFAULT_VIBRATE);

如果您想要所有默认设置,您可以通过设置notificationBuilder.setDefaults(-1)来实现它,它将其视为DEFAULT_ALL值.

有关setDefaults,请参阅android doc.

编辑：

振动延迟1000毫秒.如果您将第一个设置为0,它将立即关闭.这是一种{延迟,振动,睡眠,睡眠}模式

// Each element then alternates between delay,vibrate,sleep,sleep
 notificationBuilder.setVibrate(new long[] { 1000,1000});
