recyclerView中的listview不滚动

Question

我在 recyclerview 中有一个列表视图，如下所示：

列表视图的滚动在此实现中不起作用。

我的目标是单击按钮时列表视图切换显示和隐藏。 主用户界面在标签的 viewpager 上

   public class tabOne extends Fragment {

    RecyclerView myTabRecycler;
    adapterMainList adapter;

    public tabOne() {

    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.tab_one, container, false);

        myTabRecycler = (RecyclerView) v.findViewById(R.id.tabRC);
        myTabRecycler.setHasFixedSize(true);
        LinearLayoutManager llm = new LinearLayoutManager(G.context);
        llm.setOrientation(LinearLayoutManager.VERTICAL);
        myTabRecycler.setLayoutManager(llm);
        adapter = new adapterMainList(Utiles.getSampleCat());
        myTabRecycler.setAdapter(adapter);
        Utiles.Log(Utiles.getSampleCat().size());
        myTabRecycler.startNestedScroll(2);

        return v;
    }
    }

recyclerView 的适配器：

 public class adapterMainList extends  RecyclerView.Adapter<adapterMainList.CatViewHolder> {

    private List<retroCategory> cats;

    public adapterMainList(List<retroCategory> catList) {
        this.cats = catList;

    }


    @Override
    public int getItemCount() {
        return cats.size();
    }


    @Override
    public void onBindViewHolder(final CatViewHolder catViewHolder, final int position) {


        final retroCategory cat = cats.get(position);
        Utiles.Log("BindNow");
    }

    @Override
    public CatViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View itemView = LayoutInflater.
                from(viewGroup.getContext()).
                inflate(R.layout.adapter_item_category, viewGroup, false);
        return new CatViewHolder(itemView);
    }

    public static class CatViewHolder extends RecyclerView.ViewHolder {

        protected ListView vList;
        protected ImageView vImg;


        public CatViewHolder(View v) {
            super(v);

            vList = (ListView) v.findViewById(R.id.adapter_item_list);
            vImg = (ImageView) v.findViewById(R.id.adapter_item_img);

        }


    }
    }

物品界面：

                <ImageView

                    android:scaleType="fitXY"

        android:paddingLeft="8dp"
        android:paddingRight="8dp">

    </ListView>




</LinearLayout>

当我想滚动列表视图时，在运行应用程序上，RecyclerView 滚动而不是那个......我该如何解决这个问题？ 谢谢

抱歉英语不好

您不应在另一个可滚动视图中使用ListView。 在这种情况下，您在 RecyclerView 中使用 ListView。

使用 LinearLayout 而不是 ListView。 比如：

public class MyListLayout extends LinearLayout implements
        View.OnClickListener {

    private Adapter list;
    private View.OnClickListener mListener;

    public MyListLayout(Context context) {
        super(context);
    }

    public MyListLayout(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);

    }

    public MyListLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onClick(View v) {
        if (mListener!=null)
            mListener.onClick(v);
    }

    public void setList(Adapter list) {
        this.list = list;

        //Popolute list
        if (this.list!=null){
            for (int i=0;i<this.list.getCount();i++){
                View item= list.getView(i, null,null);
                this.addView(item);
            }
        }

    }

    public void setmListener(View.OnClickListener mListener) {
        this.mListener = mListener;
    }
}
