在ACTION_POWER_CONNECTED电池状态 [英] battery status on ACTION_POWER_CONNECTED

问题描述

我只是想知道是否有任何可能获得在对ACTION_POWER_CONNECTED触发广播接收机类电池状态？文件建议不要，但它始终是值得问：）

I'm just wondering if is there any possibility to obtain battery status in broadcast receiver class that fires on ACTION_POWER_CONNECTED? Documentation suggest not, but it is always worth to ask :)

推荐答案

呼叫 registerReceiver（空，新的IntentFilter（Intent.ACTION_BATTERY_CHANGED））。在意图则返回的最后一次广播 ACTION_BATTERY_CHANGED 播出，这在其额外的电池状态（见 BatteryManager 的键）。

Call registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED)). The Intent that is returned is the last-broadcast ACTION_BATTERY_CHANGED broadcast, which has your battery status in its extras (see BatteryManager for the keys).

如果您确定您太快调用它， ACTION_POWER_CONNECTED 之前 ACTION_BATTERY_CHANGED 调用得到，也许更新使用 AlarmManager 来安排自己在几秒钟醒一次，然后再次进行检查。

If you determine that you are calling it too soon, that ACTION_POWER_CONNECTED is invoked before ACTION_BATTERY_CHANGED gets updated, perhaps use AlarmManager to schedule yourself to wake up again in a few seconds, and check again then.
