无法识别getContext（）

Question

在getContext()中，其显示“无法从静态上下文中引用非静态方法'getContext（）'”如何解决该问题，或者应代替该调用什么。

public class CategoryAdapter extends RecyclerView.Adapter<CategoryAdapter.ViewHolder > {

private List<CategoryModel> CategoryModelList;

public CategoryAdapter(List<CategoryModel> categoryModelList) {
    CategoryModelList = categoryModelList;
}

@NonNull
@Override
public CategoryAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int viewType) {
    View view = LayoutInflater.from(ViewGroup.getContext()).Inflate(R.layout.category_item,viewGroup,false);
    return null;
}

@Override
public void onBindViewHolder(@NonNull CategoryAdapter.ViewHolder holder, int position) {

}

@Override
public int getItemCount() {
    return 0;
}

Answer 1

ViewGroup.getContext()

尝试：

viewGroup.getContext()

Answer 2

您正在使用ViewGroup，但是应该是viewGroup

Answer 3

尝试：

public class CategoryAdapter extends RecyclerView.Adapter<CategoryAdapter.ViewHolder > {
private Context context;

private List<CategoryModel> CategoryModelList;

public CategoryAdapter(List<CategoryModel> categoryModelList, Context Mcontext) {
    CategoryModelList = categoryModelList;
    this.context = Mcontext;
}

@NonNull
@Override
public CategoryAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int viewType) {
    View view = LayoutInflater.from(context).Inflate(R.layout.category_item,viewGroup,false);
    return null;
}

@Override
public void onBindViewHolder(@NonNull CategoryAdapter.ViewHolder holder, int position) {

}

@Override
public int getItemCount() {
    return 0;
}
