Multiline EditText in RecyclerView scrolling issues

Question

I have a RecyclerView that contains a multiline EditText as a list item, the EditText expands each time a line is added. The RecyclerView has a standard vertical LinearLayoutManager and a standard RecyclerView.Adapter<RecyclerView.ViewHolder> adapter with 15 of the EditText list items. I'll add the code at the end of the question.

The issue is that after you have added a number of lines to the EditText, it begins to scroll the list down each time a line is added. Eventually, after you have added enough new lines, the EditText will be scrolled off the top of the screen and loses focus. If you try to scroll back up and select the last line of the EditText, it will scroll the list back down until the EditText is off the top of the screen and it loses focus.

This isn't an issue for ListView, only for RecyclerView.

Does anyone know how to fix or get around this issue?

The line item:

<EditText xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:inputType="textMultiLine|textCapSentences"
      android:gravity="top"
      android:hint="Enter text"
      android:minLines="2"
      android:layout_margin="16dp"/>

The RecyclerViewFragment and Adapter

public class RecyclerViewFragment extends Fragment
{
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        View view = inflater.inflate(R.layout.recycler_view_fragment, container, false);

        RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
        recyclerView.setAdapter(new MyAdapter());
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

        return view;
    }

    private class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder>
    {
        @Override
        public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
        {
            View view = getActivity().getLayoutInflater().inflate(R.layout.edit_text_list_item, parent, false);

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

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

        }

        @Override
        public int getItemCount()
        {
            return 15;
        }

        private class MyViewHolder extends RecyclerView.ViewHolder
        {

            public MyViewHolder(View itemView)
            {
                super(itemView);
            }
        }
    }
}

Answer 2

EditTextView.setOnTouchListener(new View.OnTouchListener() {

    public boolean onTouch(View v, MotionEvent event) {
        // Disallow the touch request for parent scroll on touch of child view
        v.getParent().requestDisallowInterceptTouchEvent(true);
        return false;
    }
});

While Edittext on recycler view, request to not deliver touch event to its parent. This way editText will have touch event and will behave as expected
