收到通知后如何使屏幕唤醒? [英] How to make a screen wake up when a notification is received?

问题描述

对于我的应用程序，我试图在通知唤醒屏幕并显示该应用程序视图的位置获取它.我不知道如何在锁定屏幕上唤醒应用程序.我已经尝试了一些方法，但似乎没有任何效果，或者它们使应用程序崩溃了.

For my app I'm trying to get it where the notification wakes up the screen and displays a view from the app. I can't figure how to get the app to wake up when its in a lock screen. I've tried a few things but none seem to work or they crash the app.

推荐答案

有我的解决方案:

createNotification(); //your implementation
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
boolean isScreenOn = Build.VERSION.SDK_INT >= 20 ? pm.isInteractive() : pm.isScreenOn(); // check if screen is on
if (!isScreenOn) {
    PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "myApp:notificationLock");
    wl.acquire(3000); //set your time in milliseconds
}
