Android编程实现对电池状态的监视功能示例编程实现对电池状态的监视功能示例
本文实例讲述了Android编程实现对电池状态的监视功能。分享给大家供大家参考，具体如下：
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;
}
}
}
};
