android - Create Options Menu for RecyclerView-Item

Question

How do I create an Options Menu like in the following Screenshot:

The Options Menu should be opened afther clicking on the "More"-Icon of a RecyclerView Item!

My try was this:

@Override
public void onBindViewHolder(Holder holder, int position) {
    holder.txvSongTitle.setText(sSongs[position].getTitle());
    holder.txvSongInfo.setText(sSongs[position].getAlbum() + " - " + sSongs[position].getArtist());

holder.btnMore.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(mContext, "More...", Toast.LENGTH_SHORT).show();
        }
    });
}

But this causes problems because the full item is clicked if I touch on the RecyclerView Item More-Button...

Here's my RecyclerViewOnTouchListener:

public class RecyclerViewOnTouchListener implements RecyclerView.OnItemTouchListener {
    private GestureDetector mGestureDetector;
    private OnTouchCallback mOnTouchCallback;

    public RecyclerViewOnTouchListener(Context context, final RecyclerView recyclerView, final OnTouchCallback onTouchCallback) {
        mOnTouchCallback = onTouchCallback;

        mGestureDetector = 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 && onTouchCallback != null) {
                    onTouchCallback.onLongClick(child, recyclerView.getChildLayoutPosition(child));
                }

                super.onLongPress(e);
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
        View child = rv.findChildViewUnder(e.getX(), e.getY());

        if (child != null && mOnTouchCallback != null && mGestureDetector.onTouchEvent(e)) {
            mOnTouchCallback.onClick(child, rv.getChildLayoutPosition(child));
        }

        return false;
    }

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

    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }

    public interface OnTouchCallback {
        void onClick(View view, int position);
        void onLongClick(View view, int position);
    }
}

I wasn't able to find any similar problem so I hope you can help me!

It is very easy to create an option menu like this. Just add a button in your list item design. You can use the following string to display 3 vertical dots.

<TextView
    android:id="@+id/textViewOptions"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:text="&#8942;"
    android:textAppearance="?android:textAppearanceLarge" />

Now in your adapter inside onBindViewHolder() use the following code.

holder.buttonViewOption.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        //creating a popup menu
        PopupMenu popup = new PopupMenu(mCtx, holder.buttonViewOption);
        //inflating menu from xml resource
        popup.inflate(R.menu.options_menu);
        //adding click listener
        popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.menu1:
                        //handle menu1 click
                        return true;
                    case R.id.menu2:
                        //handle menu2 click
                        return true;
                    case R.id.menu3:
                        //handle menu3 click
                        return true;
                    default:
                        return false;
                }
            }
        });
        //displaying the popup
        popup.show();

    }
});

Thats it.
