我想加用寻求我的Andr​​oid应用程序中的栏屏幕的亮度，但我不知道如何做到这一点。如何添加此功能？

I would like to increase the brightness of the screen using a seek bar within my Android application, but I'm not sure how to do this. How can I add this functionality?

推荐答案

使用这个你可以设置屏幕亮度：

Using this you can set the screen brightness:

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

现在，只要你想实现像控制进度条，我会建议你实现搜索栏，所以使用这个你可以很方便地增加基础上的跟踪搜索栏的值/减小。

Now, as you want to implement progress bar like control, i would suggest you to implement SeekBar, so using this you can easily increase/decrease based on tracking value of seekbar.

这里是实现了完整的例子使用搜索栏。
