Android SDK中告诉我， PowerManager.SCREEN_DIM_WAKE_LOCK 和类似的常量pcated的API级别的德$ P $ 17。它还说， FLAG_KEEP_SCREEN_ON 在大多数情况下使用。

The Android SDK tells me that PowerManager.SCREEN_DIM_WAKE_LOCK and similar constants are deprecated as of API Level 17. It also says that FLAG_KEEP_SCREEN_ON can be used in most situations.

但是，如果这是不是这样的？我特别希望能够有灰色的屏幕，但不会关闭完全。什么是其他，更好的选择 - 或不存在简单的任何

But what if this is not the case? In particular, I want to be able to have the screen dimmed but not shut off entirely. What are other, "better" alternatives – or aren't there simply any?

推荐答案

目前还没有更好的替代品，以实际使用去precated WakeLock

There is currently no better alternative as to actually use the deprecated WakeLock.

其实你有另一种选择（但不是更好）。您可以使用 FLAG_KEEP_SCREEN_ON 与来自手动更改系统亮度的活动里面（的例如）。

Actually you have another alternative (but not better). You can use the FLAG_KEEP_SCREEN_ON in combination with changing the system brightness manually from inside your activity (example).

But what if this is not the case?

我有一个类似的情况中，我需要的屏幕为不断地对从服务（所以Activity.getWindow（ ）不可用）。在这种情况下，我使用pcated WakeLock直到Android的去$ P $来了一个新的API。

I'm having a similar situation in which I need the screen to be constantly on from a Service (so the Activity.getWindow() is not available). In this case i use the deprecated WakeLock until Android comes up with a new API.
