添加屏幕亮度控制到Android应用 [英] Adding screen brightness controls to android application

问题描述

我期待将控件添加到我的应用程序菜单中局部调整屏幕亮度，但似乎无法弄清楚如何做到这一点。我见过的例子来最大输出或暗淡的亮度，但我期待添加控件，以便用户可以控制和设置亮度级别。没有人有任何的例子，教程，源$ C ​​$ C，或只是一个地方点我在正确的方向？

I am looking to add controls to adjust screen brightness locally in my app menu but can't seem to figure out how to do it. I have seen examples to max-out or dim brightness but I am looking to add controls so that the user can control and set the brightness level. Does anyone have any examples, tutorials, source code, or just a place to point me in the right direction?

The internet claims this works, I haven't tried it though:

WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = 100 / 100.0f;
getWindow().setAttributes(lp);
