Android 可以通过BroadcastReceiver来获取电池信息改变的广播(ACTION_BATTERY_CHANGED),从而获取到相关的电池信息。

电池信息,及其对应的相关常数(参考网址:http://blog.sina.com.cn/s/blog_5d2e69770102vh59.html)

电池信息 类型 备注
status int 取得电池的状态,返回的状态类型由 android.os.BatteryManager 类定义的常量所决定,包括:
电池充电状态( BATTERY_STATUS_CHARGING )
电池放电状态( BATTERY_STATUS_DISCHARGING )
电池满电状态( BATTERY_STATUS_FULL )
电池不充电状态( BATTERY_STATUS_NOT_CHARGING )
电池未知状态( BATTERY_STATUS_UNKNOWN )
health int 取得电池的健康状态,返回的状态类型由 android.os.BatteryManager 类定义的常量所决定,包括:
电池损坏( BATTERY_HEALTH_DEAD )
电池健康( BATTERY_HEALTH_GOOD )
电池过热( BATTERY_HEALTH_OVERHEAT )
电池电压过大( BATTERY_HEALTH_OVER_VOLTAGE )
未知状态( BATTERY_HEALTH_UNKOWN )
未明示故障( BATTERY_HEALTH_UNSPECIFIED_FAILURE )
present boolean 判断当前是否存在电池
level int 取得电池的剩余容量
scale int 取得电池的总容量,通常为 100
Icon-small int 取得电池对应的图标 ID
plugged int 连接的电源插座类型,返回的状态由 android.os.BatteryManager 类定义的常量所决定,包括:
USB 电源( BATTERY_PLUGGED_USB )
交流电电源( BATTERY_PLUGGED_AC )
voltage int 取得电池的电压
temperature int 取得电池的温度,单位是摄氏度
technology String 取得电池的类型

获取电池信息的步骤:

(1) 创建BroadcastReceiver,用于结束电池信息变化的广播

private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(Intent.ACTION_BATTERY_CHANGED)) {
//TO GET BatteryInfo
}

(2) 重写onResume()方法,获取IntentFilter对象,并注册BroadcastReceiver

	protected void onResume() {
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_BATTERY_CHANGED);
registerReceiver(mBroadcastReceiver, filter);
super.onResume();
}

(3)程序在后台的时候取消注册BroadcastReceiver

	protected void onPause() {
unregisterReceiver(mBroadcastReceiver);
super.onPause();
}

public class GetBatteryInfo extends Activity {
private static final int REFRESH_TIME = 1;
