android - 我应该用什么替换 SCREEN_DIM_WAKE_LOCK？

Question

我目前正在使用以下参考代码对警报通知活动进行唤醒锁定。不过SCREEN_DIM_LOCK已经贬值了。那么，我应该用什么来代替它呢？

//Instance of wake lock for AlarmActivity
PowerManager pm = (PowerManager) this.getSystemService(Context.POWER_SERVICE);
wakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "MyWakeLock");

Answer 1

Android Developer documentation specifies that SCREEN_DIM_WAKE_LOCK should be replaced with FLAG_KEEP_SCREEN_ON. After doing a bit of digging, I turned up this...

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

It should be placed in the onCreate() method.

Answer 2

正如javadoc所说，它可以替换为FLAG_KEEP_SCREEN_ON，但这将防止屏幕变暗 - 它会保持明亮。

此 API 不应该被弃用 - 在某些情况下仍然需要它，例如“ dim ”情况。

Answer 3

Just use

WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON

In place of

PowerManager.SCREEN_DIM_WAKE_LOCK
