Android 对电池状态的监视

最近在开发一个与GPS相关的项目，因为其中涉及到了GPS的使用，众所周知，GPS是相当耗电的，因此就想着怎么能知道当前的电量，并且在电量达到一个下限的时候，及时提醒给用户，以根据情况关闭GPS，节省电量，以备电话急用，后来查资料，看API，终于找到了方法，怎么来监视电量，根据电量的变化来获取当前的电量多少，并且根据其它状态综合对手机进行管理，以达到管理最优的状态。

    下面是代码：

private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() {int intLevel = 0;int intScale = 0;public void onReceive(Context context, Intent intent) {String action = intent.getAction();/** 如果捕捉到的action是ACTION_BATTERY_CHANGED， 就运行onBatteryInfoReceiver()*/if (Intent.ACTION_BATTERY_CHANGED.equals(action)) {intLevel = intent.getIntExtra("level", 0);intScale = intent.getIntExtra("scale", 100);// 电池伏数Log.d("Battery V", "" + intent.getIntExtra("voltage", 0));// 电池温度Log.d("Battery T", "" + intent.getIntExtra("temperature", 0));BatteryV = "当前电压为：" + intent.getIntExtra("voltage", 0);BatteryT = "当前温度为：" + intent.getIntExtra("temperature", 0);switch (intent.getIntExtra("status",BatteryManager.BATTERY_STATUS_UNKNOWN)) {case BatteryManager.BATTERY_STATUS_CHARGING:BatteryStatus = "充电状态";break;case BatteryManager.BATTERY_STATUS_DISCHARGING:BatteryStatus = "放电状态";break;case BatteryManager.BATTERY_STATUS_NOT_CHARGING:BatteryStatus = "未充电";break;case BatteryManager.BATTERY_STATUS_FULL:BatteryStatus = "充满电";break;case BatteryManager.BATTERY_STATUS_UNKNOWN:BatteryStatus = "未知道状态";break;}switch (intent.getIntExtra("plugged",BatteryManager.BATTERY_PLUGGED_AC)) {case BatteryManager.BATTERY_PLUGGED_AC:BatteryStatus2 = "AC充电";break;case BatteryManager.BATTERY_PLUGGED_USB:BatteryStatus2 = "USB充电";break;}switch (intent.getIntExtra("health",BatteryManager.BATTERY_HEALTH_UNKNOWN)) {case BatteryManager.BATTERY_HEALTH_UNKNOWN:BatteryTemp = "未知错误";break;case BatteryManager.BATTERY_HEALTH_GOOD:BatteryTemp = "状态良好";break;case BatteryManager.BATTERY_HEALTH_DEAD:BatteryTemp = "电池没有电";break;case BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE:BatteryTemp = "电池电压过高";break;case BatteryManager.BATTERY_HEALTH_OVERHEAT:BatteryTemp = "电池过热";break;}}}};转自：http://ophonesdn.com/blog/blacklee/showBlog/publicshow/9981abba-387d-4577-826b-4ad8523bfd9f?count=&max=&index= 转载请声明
