语音社交源码群聊开发，需要实现礼物打赏功能

语音社交源码群聊打赏礼物的效果如图：

语音社交源码礼物和背包都是可以很多页的，可能这是唯一稍微麻烦一点的地方，直接贴全部详细代码。
1、首先写一个名为FragmentRoomDetailGift的DialogFragment，是整个的语音社交源码的弹框（包括礼物和背包模块，以及点击可以跳转到别的模块的小游戏“摇糖罐”），FragmentRoomDetailGift继承自我封装的抽象类BaseDialogFragment2。
2、语音社交源码礼物和背包的分页，思路是创建一个view的集合，每页设置8个礼物，下面会贴出礼物的页面GiftFragment.kt的代码。
3、关于语音社交源码送礼物走的接口就是看具体情况了，现在送礼物走的是接口，然后回调走的websocket，通知语音社交源码房间里的其他人进行下一步操作。其实最好的方案是进房间走一次接口，其他所有的操作都走websocket，关于websocket这个分类其他文章会写。

BaseDialogFragment2.kt的代码:

abstract class BaseDialogFragment2 : DialogFragment() {protected val TAG = javaClass.simpleNameprotected lateinit var mContext: Contextabstract val layoutRes: Intoverride fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)mContext = activity as Context}override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {var rootView = inflater.inflate(layoutRes, null)mContext = activity as Contextreturn rootView}override fun onViewCreated(view: View, savedInstanceState: Bundle?) {initView()super.onViewCreated(view, savedInstanceState)}private fun initView() {initAll()setListener()processLogic()}protected abstract fun initAll()protected abstract fun setListener()protected abstract fun processLogic()protected fun hideSoftKeyboard(view: View) {activity?.inputMethodManager?.hideSoftInputFromWindow(view.windowToken, 0)}protected fun showSoftKeyboard(view: View) {activity?.inputMethodManager?.showSoftInput(view, InputMethodManager.SHOW_FORCED)}
}

FragmentRoomDetailGift.kt的代码：
