适配器类中的视图组

Question

我为项目列表构建了一个Recyclarview，并希望在适配器中标识它们，因此我创建了一个适配器类并重写onCreateViewHolder方法来填充数据，当我通过ViewGroup类从上下文类中创建一个名为context的对象时，通过以下行调用getContext方法：

Context context = ViewGroup.getContext();

但是无法从静态上下文中引用方法getContext。

我尝试使用与getContext相等的getApplicationContext方法，但无法解决，我尝试打开ViewGroup类，但找不到getContext方法

/**
     *
     * This gets called when each new ViewHolder is created. This happens when the RecyclerView
     * is laid out. Enough ViewHolders will be created to fill the screen and allow for scrolling.
     *
     * @param viewGroup The ViewGroup that these ViewHolders are contained within.
     * @param viewType  If your RecyclerView has more than one type of item (which ours doesn't) you
     *                  can use this viewType integer to provide a different layout. See
     *                  {@link android.support.v7.widget.RecyclerView.Adapter#getItemViewType(int)}
     *                  for more details.
     * @return A new NumberViewHolder that holds the View for each list item
     */
    @NonNull
    @Override
    public NumberViewHolde onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
       Context context = ViewGroup.getContext();
       int layoutIdForListItem = R.layout.number_list_item;
       LayoutInflater inflater = LayoutInflater.from(context);
       boolean ShouldAttachToParentImmediately = false;
       View view =inflater.inflate(layoutIdForListItem,ViewGroup,ShouldAttachToParentImmediately);
       NumberViewHolde viewHolde = new NumberViewHolde(view);
       return viewHolde;

    }

getContext方法getContext不能从静态上下文中引用
