RecyclerView item onClick

RecyclerView does not have an OnItemClickListener like it's predecessor, ListView. However, detecting item clicks is pretty simple.

Set an OnClickListener in your ViewHolder creation:

private class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>  {

    public static class ViewHolder extends RecyclerView.ViewHolder
            implements View.OnClickListener {
        private String mItem;
        private TextView mTextView;

        public ViewHolder(View view) {
            super(view);
            view.setOnClickListener(this);
            mTextView = (TextView) view;
        }

        public void setItem(String item) {
            mItem = item;
            mTextView.setText(item);
        }

        @Override
        public void onClick(View view) {
            Log.d(TAG, "onClick " + getPosition() + " " + mItem);
        }
    }

    private String[] mDataset;

    public MyAdapter(String[] dataset) {
        mDataset = dataset;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.list_item, parent, false);
        ViewHolder vh = new ViewHolder(v);
        return vh;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.setItem(mDataset[position]);
    }

    @Override
    public int getItemCount() {
        return mDataset.length;
    }
}

Add touch feedback to your item layout:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:gravity="center_vertical"
    android:paddingStart="?android:attr/listPreferredItemPaddingStart"
    android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
    android:minHeight="?android:attr/listPreferredItemHeightSmall"
    android:background="?android:attr/selectableItemBackground"
/>
