Android中电池信息(Battery information)的取得  
这里介绍电池信息的取得.  
Android.content.BroadcastReceiver类  
Android.os.BatteryManager类  
  
● 电池信息的取得，调用registerReceiver()方法。  
第1个参数，设置BroadcastReceiver实例  
第2个参数，设置追加了Intent.ACTION\_BATTERY\_CHANGED处理的IntentFilter实例。  
● 在BroadcastReceiver的onReceive()事件，接收到的Intent.ACTION\_BATTERY\_CHANGED，包括下面的信息。  
“status”（int类型）…状态，定义值是BatteryManager.BATTERY\_STATUS\_XXX。  
“health”（int类型）…健康，定义值是BatteryManager.BATTERY\_HEALTH\_XXX。  
“present”（boolean类型）  
“level”（int类型）…电池剩余容量  
“scale”（int类型）…电池最大值。通常为100。  
“icon-small”（int类型）…图标ID。  
“plugged”（int类型）…连接的电源插座，定义值是BatteryManager.BATTERY\_PLUGGED\_XXX。  
“voltage”（int类型）…mV。  
“temperature”（int类型）…温度，0.1度单位。例如表示197的时候，意思为19.7度。  
“technology”（String类型）…电池类型，例如，Li-ion等等。
