1、亮屏和暗屏的控制

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);

PowerManager.WakeLock wakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "TAG");

//?點亮

wakeLock.acquire();

//釋放鎖，屏幕熄滅。

wl.release();

2、亮屏和暗屏還有解鎖的監聽事件

final IntentFilter filter = new IntentFilter();

filter.addAction(Intent.ACTION_SCREEN_OFF);

filter.addAction(Intent.ACTION_SCREEN_ON);

filter.addAction(Intent.ACTION_USER_PRESENT);

registerReceiver(mBatInfoReceiver, filter);

BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() {

@Override

public void onReceive(final Context context, final Intent intent) {

String action = intent.getAction();

if(Intent.ACTION_SCREEN_ON.equals(action))

{

Log.d(TAG, "screen is on...");

}

else if(Intent.ACTION_SCREEN_OFF.equals(action))

{

Log.d(TAG, "screen is off...");

}

else if(Intent.ACTION_USER_PRESENT.equals(action))

{

Log.d(TAG, "screen is unlock...");

}

}

};
