AndroidStudio监测电池电量变化广播代码

以下是在Android Studio中监听电池电量变化广播的代码：

public class BatteryBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        int batteryLevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
        int batteryScale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
        float batteryPercentage = batteryLevel * 100 / (float)batteryScale;

        // Do something with batteryPercentage
    }
}

在你的AndroidManifest.xml文件中添加以下代码来注册广播接收器：

<receiver android:name=".BatteryBroadcastReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BATTERY_CHANGED" />
    </intent-filter>
</receiver>

当电池电量变化时，`onReceive`方法将被调用，并且可以通过`intent`对象获取电池电量信息。
