无法解析方法 setOnChildClickListener

Question

这是我的整个活动代码，如果需要，我也可以发布我的 xml。

public class Main_Activityextends AppCompatActivity {
private RecyclerView recyclerview;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    recyclerview = (RecyclerView) findViewById(R.id.recyclerview);
    recyclerview.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
    List<ExpandableListViewAdapter.Item> data = new ArrayList<>();

    data.add(new ExpandableListViewAdapter.Item(ExpandableListViewAdapter.HEADER, "Terms of usage"));
    data.add(new ExpandableListViewAdapter.Item(ExpandableListViewAdapter.CHILD, "never eat"));
    data.add(new ExpandableListViewAdapter.Item(ExpandableListViewAdapter.CHILD, "bluhhhhh"));

    recyclerview.setAdapter(new ExpandableListViewAdapter(data));

     recyclerview.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
        @Override
        public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
            return true;
        }

    });

代码在没有clickListener 的情况下完美运行，但我希望在单击数组的某个子项时发生一个动作，但现在它显示Cannot resolve method setOnChildClickListener(anonymous android.widget.ExpendableListView.OnChildClickListener) 尽管recycleView 是我的Adapter，任何帮助将不胜感激

简而言之，RecyclerView 不支持OnChildClickListener，因为它不打算直接替代ListView。

如需了解原因，请查看this stackoverflow answer

您应该改为在您的 ViewHolder 类中实现 View.OnClickListener，如下所示：

public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    // Your view fields here

    public ViewHolder(View itemLayoutView) {
        super(itemLayoutView);

        // Assign view fields

        itemLayoutView.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        // Do your thing here
    }
}
