android换肤功能如何动态获取控件中背景图片的资源id?

 //先获取本地资源引用名称，type name是R.drawable.background中的"drawable"，entry name是"background"
 String resTypeName = getContext().getResources().getResourceTypeName(id);
 String resEntryName = getContext().getResources().getResourceEntryName(id);
 //然后创建皮肤包所在应用的Context
 Context apk = getContext().createPackageContext(packageName,
   Context.CONTEXT_IGNORE_SECURITY)
 //然后就是获取皮肤包中的资源id了
 int drawavleId = apk.getResources().getIdentifier(resEntryName, resTypeName,
   apk.getPackageName()); 

 private List skinViewList = new ArrayList (); private void scanViewGroup(ViewGroup group, List skinViewList, Resources res) {
  //first we need check if this ViewGroup have a background
  if(group.getId() != View.NO_ID
    && res.getResourceEntryName(group.getId()).contains(SKIN_PATTERN)
    && !skinViewList.contains(group)) {
   skinViewList.add(group.getId());
  }

  //second check its child view
  View child;

  for(int i = 0; i 

  //先判断前面扫描的skinViewList是否为空，不为空意味着有控件需要换肤
  if(skinViewList != null && skinViewList.size() > 0) {
   int viewId = -1, backgroundId = -1;
   for(int i = 0; i 
            var cpro_id = "u6885494";
