MainActivity：

@AILayout(R.layout.activity_main)
public class MainActivity extends AIActionBarActivity implements RapidFloatingActionContentLabelList.OnRapidFloatingActionContentLabelListListener {

    @AIView(R.id.activity_main_rfal)

        items.add(new RFACLabelItem<Integer>()
                        .setLabel("Github: wangjiegulu")
                        .setResId(R.mipmap.ico_test_d)

                        .setLabelBackgroundDrawable(ABShape.generateCornerShapeDrawable(0xaa000000, ABTextUtil.dip2px(context, 4)))
                        .setWrapper(1)
        );
        items.add(new RFACLabelItem<Integer>()
                        .setLabel("WangJie")
                        .setResId(R.mipmap.ico_test_b)
                        .setIconNormalColor(0xff056f00)
                        .setIconPressedColor(0xff0d5302)

                        .setResId(R.mipmap.ico_test_a)
                        .setIconNormalColor(0xff283593)
                        .setIconPressedColor(0xff1a237e)
                        .setLabelColor(0xff283593)
                        .setWrapper(3)
        );
        rfaContent
                .setItems(items)
                .setIconShadowRadius(ABTextUtil.dip2px(context, 5))
                .setIconShadowColor(0xff888888)
                .setIconShadowDy(ABTextUtil.dip2px(context, 5))
        ;
        rfabHelper = new RapidFloatingActionHelper(
                context,
                rfaLayout,
                rfaBtn,
                rfaContent
        ).build();
    }

    @Override
    public void onRFACItemLabelClick(int position, RFACLabelItem item) {
        Toast.makeText(getContext(), "clicked label: " + position, Toast.LENGTH_SHORT).show();
        rfabHelper.toggleContent();
    }

    @Override
    public void onRFACItemIconClick(int position, RFACLabelItem item) {
        Toast.makeText(getContext(), "clicked icon: " + position, Toast.LENGTH_SHORT).show();
        rfabHelper.toggleContent();
    }
}

RFAB also needs an implementation of RapidFloatingActionContent to fill and assign content of RFAB when it expands.

Here is a quick solution of RapidFloatingActionContent:RapidFloatingActionContentLabelList.You can add some items（RFACLabelItem，of course not recommended to add too many items），and config color, drawable, shadow, background image, text size, color of label and animation of each item.

To preview the demo: The top picture effects or Inbox of Google.

At last，you need combine them by RapidFloatingActionButtonHelper.

About expand style：

If you don't like RapidFloatingActionContentLabelList，you can expand your content style. Extend com.wangjie.rapidfloatingactionbutton.RapidFloatingActionContent, initialize the content layout and style，and invoke setRootView(xxx); method. If you want to add more animations，override those methods：

public void onExpandAnimator(AnimatorSet animatorSet);
public void onCollapseAnimator(AnimatorSet animatorSet);

add your animations to the animatorSet.
