直接上代码:

// 声明消息处理过程

另外还有一份别人的参考代码:
[java]
检测到现在在电源状态:
IntentFiltermIntentFilter = new IntentFilter();
mIntentFilter.addAction(Intent.ACTION_BATTERY_CHANGED);
registerReceiver(mIntentReceiver, mIntentFilter);
//声明消息处理过程
private BroadcastReceiver mIntentReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
//要看看是不是我们要处理的消息
if (action.equals(Intent.ACTION_BATTERY_CHANGED)) {
//电池电量，数字
Log.d("Battery", "" + intent.getIntExtra("level", 0));
//电池最大容量
Log.d("Battery", "" + intent.getIntExtra("scale", 0));
//电池伏数
Log.d("Battery", "" + intent.getIntExtra("voltage", 0));
//电池温度
Log.d("Battery", "" + intent.getIntExtra("temperature", 0));
//电池状态，返回是一个数字
// BatteryManager.BATTERY_STATUS_CHARGING 表示是充电状态
// BatteryManager.BATTERY_STATUS_DISCHARGING 放电中
// BatteryManager.BATTERY_STATUS_NOT_CHARGING 未充电
// BatteryManager.BATTERY_STATUS_FULL 电池满
Log.d("Battery", "" + intent.getIntExtra("status", BatteryManager.BATTERY_STATUS_UNKNOWN));
//充电类型 BatteryManager.BATTERY_PLUGGED_AC 表示是充电器，不是这个值，表示是 USB
Log.d("Battery", "" + intent.getIntExtra("plugged", 0));
//电池健康情况，返回也是一个数字
//BatteryManager.BATTERY_HEALTH_GOOD 良好
//BatteryManager.BATTERY_HEALTH_OVERHEAT 过热
//BatteryManager.BATTERY_HEALTH_DEAD 没电
//BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE 过电压
//BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE 未知错误
Log.d("Battery", "" + intent.getIntExtra("health", BatteryManager.BATTERY_HEALTH_UNKNOWN));
}
}
};
