Create Options Menu for RecyclerView-Item

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.
