Android Floating Action Button Menu Example
Hola amigos en esta ocasión vamos a crear un menu flotante con el control Floating Action Button.
Crear Proyecto Android Floating Action Button (Aquí)
Crearemos un proyecto para nuestra aplicación de la siguiente forma y teniendolo listo continuaremos.
Diseño Android Floating Action Button
Vamos a crear el diseño de nuestra aplicación. En el archivo activity_main.xml

<!-- if you are not using Snackbar with this activity then remove below line from every place of the file:

the above line enables the view to Scrolls up with the snackbar as, the FAB do automaticaly scrolls up
when the snackbar appear, so if snackbar is not used please remove the above line from every view present in the xml-->

Ahora vamos a crear el código de nuestra aplicación para desarrollar este ejemplo y abriremos el archivo MaintActivity.Añadiremos un paquete y crearemos utils donde crearemos la siguiente clase. MoveUpwardBehavior.
import android.content.Context;
import android.support.design.widget.CoordinatorLayout;
import android.support.design.widget.Snackbar;
import android.support.v4.view.ViewCompat;
import android.util.AttributeSet;
import android.view.View;
/**
* Created by Ajay on 07-03-2017.
*/
//Use this class only if you want toslide up the FAB whenever the seekbar appear, if u don't want this funcionality delete this file
public class MoveUpwardBehavior extends CoordinatorLayout.Behavior<View> {
public MoveUpwardBehavior() {
super();
}
public MoveUpwardBehavior(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public boolean layoutDependsOn(CoordinatorLayout parent, View child, View dependency) {
return dependency instanceof Snackbar.SnackbarLayout;
}
@Override
public boolean onDependentViewChanged(CoordinatorLayout parent, View child, View dependency) {
float translationY = Math.min(0, ViewCompat.getTranslationY(dependency) - dependency.getHeight());
ViewCompat.setTranslationY(child, translationY);
return true;
}
//you need this when you swipe the snackbar(thanx to ubuntudroid's comment)
public void onDependentViewRemoved(CoordinatorLayout parent, View child, View dependency) {
ViewCompat.animate(child).translationY(0).start();
}
}
import android.animation.Animator;

}
private void showFABMenu(){

fabLayout1.setVisibility(View.VISIBLE);
fabLayout2.setVisibility(View.VISIBLE);
fabLayout3.setVisibility(View.VISIBLE);
fabBGLayout.setVisibility(View.VISIBLE);
fab.animate().rotationBy(180);
fabLayout1.animate().translationY(-getResources().getDimension(R.dimen.standard_55));
fabLayout2.animate().translationY(-getResources().getDimension(R.dimen.standard_100));
fabLayout3.animate().translationY(-getResources().getDimension(R.dimen.standard_145));
}
private void closeFABMenu(){

fabLayout2.animate().translationY(0);
fabLayout3.animate().translationY(0).setListener(new Animator.AnimatorListener() {
@Override
public void onAnimationStart(Animator animator) {
}
@Override
public void onAnimationEnd(Animator animator) {
if(!isFABOpen){
fabLayout1.setVisibility(View.GONE);
fabLayout2.setVisibility(View.GONE);
fabLayout3.setVisibility(View.GONE);
}
}
@Override
public void onAnimationCancel(Animator animator) {
}
@Override
public void onAnimationRepeat(Animator animator) {
}
});
}
@Override
public void onBackPressed() {
if(isFABOpen){
closeFABMenu();
}else{
super.onBackPressed();
}
}
}Y por ultimo.
Crear Emulador AVD (Aquí)
Ahora crearemos nuestro emulador para ejecutar nuestro ejemplo y ver nuestro Floating Action Button Menu en ejecución.
