e. 我们上面说到要将服务Service的绑定与解绑与悬浮框的开启和关闭相结合，所以既然我们在服务的onCreate()方法中开启了悬浮框，那么就应该在其onDestroy()方法中对悬浮框进行关闭，关闭悬浮框的本质是将相关View给移除掉，在服务的onDestroy()方法中执行如下代码：

@Override

public void onDestroy() {

super.onDestroy();

if (mFloatingLayout != null) {

// 移除悬浮窗口

mWindowManager.removeView(mFloatingLayout);

mFloatingLayout = null;

Constents.isShowFloatWindow = false;

}

}

f. 服务的绑定方式有bindService和startService两种，使用不同的绑定方式其生命周期也会不一样，已知我们需要让悬浮框在视频通话activity finish掉的时候也顺便关掉，那么理所当然我们就应该采用bind方式来启动服务，让他的生命周期跟随他的开启者，也即是跟随开启它的activity生命周期。

intent = new Intent(this, FloatVideoWindowService.class);//开启服务显示悬浮框

bindService(intent, mVideoServiceConnection, Context.BIND_AUTO_CREATE);

ServiceConnection mVideoServiceConnection = new ServiceConnection() {

@Override

public void onServiceConnected(ComponentName name, IBinder service) {

// 获取服务的操作对象

FloatVideoWindowService.MyBinder binder = (FloatVideoWindowService.MyBinder) service;

binder.getService();

}

@Override

public void onServiceDisconnected(ComponentName name) {

}

};

Service完整代码如下：

/**

public class FloatVideoWindowService extends Service {

private WindowManager mWindowManager;

private WindowManager.LayoutParams wmParams;
