是否有一个HTC特有的解决办法是什么？

doesn't work on HTC Desire with Automatic brightness checked in Settings > Display > Brightness.
Is there a HTC-specific workaround for that?

推荐答案

当然，你看不到任何变化，因为这些设置都设置为自动亮度。这意味着，任何手动更改被忽略。还是我失去了一些东西？

Of course you don't see any changes since the settings are set to Automatic Brightness. That means, any manual changes are disregarded. Or am I missing something?

我刚刚测试了一个的的HTC Desire HD（2.3.5）的和屏幕亮度的 DOES 的变化约1秒钟，但随后会立即重新调整/由自动亮度覆盖。但是，如果取消在设置自动亮度选项，就可以看到该值已正确更改。

I've just tested it on a HTC Desire HD (2.3.5) and the screen brightness DOES change for about a second, but then it's immediately re-adjusted/overwritten by the automatic brightness. However, if you uncheck Auto Brightness option in the settings, you can see that the value has changed correctly.

因此​​，国际海事组织一切工作正常。如果您希望您的更改生效，您可能需要关闭自动亮度第一：

So, imo everything is working as expected. If you want your changes to take effect you might have to disable Auto Brightness first:

Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_BRIGHTNESS_MODE, Settings.System.SCREEN_BRIGHTNESS_MODE_MANUAL);
