有没有办法从Android SDK中获取电池信息？比如电池的剩余电量等？我找不到它通过文档。

Is there a way to get battery information from the Android SDK? Such as battery life remaining and so on? I cannot find it through the docs.

推荐答案

您可以注册一个Intent接收器来接收广播的ACTION_BATTERY_CHANGED：http://developer.android.com/reference/android/content/Intent.html#ACTION_BATTERY_CHANGED.该文档说，广播是粘性的，所以你可以即使在电池状态发生变化的时刻抓住它。

You can register an Intent receiver to receive the broadcast for ACTION_BATTERY_CHANGED: http://developer.android.com/reference/android/content/Intent.html#ACTION_BATTERY_CHANGED. The docs say that the broadcast is sticky, so you'll be able to grab it even after the moment the battery state change occurs.
