Question

我正在使用以下布局在recyclerView中显示项目列表。但textview anchorGravity在滚动时从一个角落跳到另一个角落。

滚动后，大多数项目都会被带到原始位置。为什么会这样？

我该如何解决？

ADAPTER

public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.MyViewHolder> {

    private ArrayList<DataModel> dataSet;

    public static class MyViewHolder extends RecyclerView.ViewHolder {

        TextView textViewName;
        TextView textViewVersion;
        ImageView imageViewIcon;

        public MyViewHolder(View itemView) {
            super(itemView);
            this.textViewName = (TextView) itemView.findViewById(R.id.textViewName);
            this.textViewVersion = (TextView) itemView.findViewById(R.id.textViewVersion);
        }
    }

    public CustomAdapter(ArrayList<DataModel> data) {
        this.dataSet = data;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent,
                                           int viewType) {
        View view = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.item_shopperitems, parent, false);

        view.setOnClickListener(MainActivity.myOnClickListener);

        MyViewHolder myViewHolder = new MyViewHolder(view);
        return myViewHolder;
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, final int listPosition) {

        TextView textViewName = holder.textViewName;
        TextView textViewVersion = holder.textViewVersion;

       textViewName.setText(dataSet.get(listPosition).getName());
       textViewVersion.setText(dataSet.get(listPosition).getVersion());
    }

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

注意

如果我有一个简单的线性布局，也没有任何孩子。出现此问题。所以我认为这个问题与CoordinatorLayout

有关

CoordinatorLayout layout_anchorGravity在滚动时跳转？
