根据项目要求，需要在setting中添加一项专门管理直播设置的内容，添加步骤如下（参考displaysetting 进行添加）：
- 添加liveSetting到SettingsHomepageActivity

参考displaysetting，将电池相关的setting更改为livesetting，提供livesetting的fragment：com.android.settings.LiveSettings ，controller：com.android.settings.klive.TopLevelLivePreferenceController
- 参考displaysetting 新建LiveSettings 、TopLevelLivePreferenceController和R.xml.live_settings
