android broadcast实例

android broadcast实例对于感兴趣的可以参考。
private BroadcastReceiver batInfoReceiver = new BroadcastReceiver() {

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);
onBatteryInfoReceiver(intLevel, intScale);
}
}
};
