亮屏

新建个工具类

public class util {
    /*亮屏*/
    public static void wakeUpAndUnlock(Context context){
        //屏锁管理器
        KeyguardManager km= (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
        KeyguardManager.KeyguardLock kl = km.newKeyguardLock("unLock");
        //解锁
        kl.disableKeyguard();
        //获取电源管理器对象
        PowerManager pm=(PowerManager) context.getSystemService(Context.POWER_SERVICE);
        //获取PowerManager.WakeLock对象,后面的参数|表示同时传入两个值,最后的是LogCat里用的Tag
        PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP |
                PowerManager.SCREEN_DIM_WAKE_LOCK,"bright");
        //点亮屏幕
        wl.acquire();
        //释放
        wl.release();
    }
}

调用

util.wakeUpAndUnlock(MainActivity.this);
