Handle Button click inside a row in RecyclerView

I am using following code for handling row clicks. (source)

static class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {

private GestureDetector gestureDetector;
private ClickListener clickListener;

public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final ClickListener clickListener) {
this.clickListener = clickListener;
gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
@Override
public boolean onSingleTapUp(MotionEvent e) {
return true;
}

@Override
public void onLongPress(MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null) {
clickListener.onLongClick(child, recyclerView.getChildPosition(child));
}
}
});
}

@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {

View child = rv.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
clickListener.onClick(child, rv.getChildPosition(child));
}
return false;
}

@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
}


This works however, if I want to have say a delete button on each row. I am not sure to how to implement that with this.

I attached OnClick listener to delete button which works (deletes the row) but it also fires the onclick on full row.

Can anybody help me in how to avoid full row click if a single button is clicked.

Thanks.

Answer

this is how I handle multiple onClick events inside a recyclerView:

public static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener{

        public ImageView iconImageView;
        public TextView iconTextView;

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

            iconImageView = (ImageView) itemView.findViewById(R.id.myRecyclerImageView);
            iconTextView = (TextView) itemView.findViewById(R.id.myRecyclerTextView);

            itemView.setOnClickListener(this);
            iconTextView.setOnClickListener(this);
            iconImageView.setOnLongClickListener(this);
        }

        // onClick Listener for view
        @Override
        public void onClick(View v) {

            if (v.getId() == iconTextView.getId()){
                Toast.makeText(v.getContext(), "ITEM PRESSED = " + String.valueOf(getAdapterPosition()), Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(v.getContext(), "ROW PRESSED = " + String.valueOf(getAdapterPosition()), Toast.LENGTH_SHORT).show();
            }
        }


        //onLongClickListener for view
        @Override
        public boolean onLongClick(View v) {

            final AlertDialog.Builder builder = new AlertDialog.Builder(v.getContext());
            builder.setTitle ("Hello Dialog")
                    .setMessage ("LONG CLICK DIALOG WINDOW FOR ICON " + String.valueOf(getAdapterPosition()))
                    .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {

                        }
                    });

            builder.create().show();
            return true;
        }
    }

To get which item was clicked you match the view id i.e. v.getId() == whateverItem.getId()

Hope this approach helps!
