推荐答案

您可以通过注册一个接收器，用于操作的 Intent.ACTION_BATTERY_CHANGED 获取的电池寿命与广播接收器的帮助。我的答案是唯一的关键，获得Android开发者网站上的信息。

You can get battery life with help of broadcast receiver by registering a receiver for action Intent.ACTION_BATTERY_CHANGED. My answer is key only, get information from Android Developers website.

通过使用下面的语句中的onReceive（BroadcastReceiver的的）方法与上述意图的动作，你会得到现有的电池电量（如50％，60％等）。但你不能估计剩余的时间，因为一些应用程序可能会消耗更多的功率。所以，我认为电池电量，以剩余时间转换将不会给出正确的结果。

By using the below statement in onReceive() method of BroadcastReceiver with above Intent action, you will get battery level currently available(e.g., 50%, 60%, etc.). But you can't estimate the time remaining, because some apps may consume more power. So i think battery level to time remaining conversion won't give correct result.

battery_level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);

我希望这可以帮助你。
