Android保持屏幕常亮2种实现方法
方法一：
<uses-permissionandroid:name="android.permission.WAKE_LOCK"/>
privatePowerManagerpowerManager=null; privateWakeLockwakeLock=null; powerManager=(PowerManager)this.getSystemService(Service.POWER_SERVICE); wakeLock=this.powerManager.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK,"MyLock"); //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);
