Java 当我的应用程序收到通知时,打开屏幕背光
当我的应用程序收到通知时,我需要打开屏幕背光。 我听到声音、LED灯亮起和振动,但屏幕一直关闭 我尝试使用PowerManager:Java 当我的应用程序收到通知时,打开屏幕背光,java,android,Java,Android,当我的应用程序收到通知时,我需要打开屏幕背光。 我听到声音、LED灯亮起和振动,但屏幕一直关闭 我尝试使用PowerManager: PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag"); wl.acquire(); ..scree
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
wl.acquire();
..screen will stay on during this section..
wl.release();
但没有结果
通知代码如下所示:
public void showNotification( String contentTitle, String contentText ) {
int icon = R.drawable.notification;
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, contentTitle, when);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.defaults |= Notification.DEFAULT_LIGHTS;
Intent notificationIntent = new Intent(this, myapp.class);
Context context = this.getApplicationContext();
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.setLatestEventInfo(this, contentTitle, contentText, contentIntent);
NotificationManager nm = (NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
v.vibrate(300);
notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "/" + R.raw.sonar_ping);
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.ledARGB = 0x00000000;
notification.ledOnMS = 0;
notification.ledOffMS = 0;
nm.notify(1, notification);
}
当通知显示在状态栏中时,如何打开屏幕?
我需要在这段代码中添加什么才能实现这一点
谢谢你的建议和帮助。试试这个
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |
PowerManager.ACQUIRE_CAUSES_WAKEUP |
PowerManager.ON_AFTER_RELEASE, "WakeLock");
wakeLock.acquire();
别忘了释放它。试试这个
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |
PowerManager.ACQUIRE_CAUSES_WAKEUP |
PowerManager.ON_AFTER_RELEASE, "WakeLock");
wakeLock.acquire();
别忘了把它发布。可能的副本可能的副本谢谢。这就是我一直在寻找的解决方案。
PowerManager.FULL\u WAKE\u LOCK
已被弃用。没有它怎么办?大卫,你可以使用PowerManager.SCREEN\u BRIGHT\u WAKE\u LOCK
或PowerManager.SCREEN\u DIM\u WAKE\u LOCK
