android - 如何处理屏幕亮度

Question

**有什么方法可以让我们在整个应用程序中始终保持屏幕开启，但在我们触摸一次又一次醒来后，它也应该变暗，请帮忙提前谢谢

Answer 1

试试这个代码：

WindowManager.LayoutParams params = 
getWindow().getAttributes();
params.flags |= LayoutParams.FLAG_KEEP_SCREEN_ON;
params.screenBrightness = YourValue;
getWindow().setAttributes(params);

Answer 2

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
 PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Tag");
 wl.acquire();
   //..screen will stay on during this section..
 wl.release();
