Android编程实现检测当前电源状态的方法

本文实例讲述了Android编程实现检测当前电源状态的方法。分享给大家供大家参考，具体如下：

检测到现在在电源状态:

IntentFilter mIntentFilter = 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));
   }
  }
};

希望本文所述对大家Android程序设计有所帮助。
