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; } } } };

这些信息就是监听广播，根据广播的信息进行判断，如果是电量变化的广播，那么就根据这些信息，更新数据，从而进行分析！

希望本文所述对大家Android程序设计有所帮助。
