이런 버튼을 말씀하시는 거라면 아래의 링크에서 제공되는 오픈소스를 적용하면 좋을것 같습니다. https://github.com/gowong/material-sheet-fab

사용법이라면 build.gradle에 compile 'com.gordonwong:material-sheet-fab:1.2.1'를 적용하시고

클래스를 만들어서 FAB버튼을 구현해주시면 됩니다.

import android.support.design.widget.FloatingActionButton;

public class Fab extends FloatingActionButton implements AnimatedFab {

   /**
    * Shows the FAB.
    */
    @Override
    public void show() {
        show(0, 0);
    }

    /**
     * Shows the FAB and sets the FAB's translation.
     *
     * @param translationX translation X value
     * @param translationY translation Y value
     */
    @Override
    public void show(float translationX, float translationY) {
        // NOTE: Using the parameters is only needed if you want
        // to support moving the FAB around the screen.
        // NOTE: This immediately hides the FAB. An animation can 
        // be used instead - see the sample app.
        setVisibility(View.VISIBLE);
    }

    /**
     * Hides the FAB.
     */
    @Override
    public void hide() {
        // NOTE: This immediately hides the FAB. An animation can
        // be used instead - see the sample app.
        setVisibility(View.INVISIBLE);
    }
}
