Android保持屏幕常亮2种实现方法

方法一:

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


private PowerManager powerManager = null;

private WakeLock wakeLock = null;

 

powerManager = (PowerManager) this.getSystemService(Service.POWER_SERVICE);

wakeLock = this.powerManager.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Lock");

//是否需计算锁的数量

wakeLock.setReferenceCounted(false);

 

//请求常亮,onResume()

wakeLock.acquire();

 

//取消屏幕常亮,onPause()

wakeLock.release();


 

方法二:

直接在onCreate()里,不用权限

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
