FloatingToolbar

A toolbar that morphs from a FloatingActionButton

Inspired by the material design spec: https://www.google.com/design/spec/components/buttons-floating-action-button.html#buttons-floating-action-button-transitions

Available from API 14.

How to use

#####1. Add the following to your build.gradle:

repositories{
  maven { url "https://jitpack.io" }
}

dependencies {
  compile 'com.github.rubensousa:FloatingToolbar:0.3'
}

#####2. Add FloatingToolbar as a direct child of CoordinatorLayout and before the FloatingActionButton:

<android.support.design.widget.CoordinatorLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/coordinatorLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">
    
    <!-- Appbar -->

    <com.github.rubensousa.floatingtoolbar.FloatingToolbar
        android:id="@+id/floatingToolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:layout_gravity="bottom"
        app:floatingMenu="@menu/main" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:src="@drawable/ic_share_black_24dp" />
        
        
</android.support.design.widget.CoordinatorLayout>

#####3. Specify a menu resource file or custom layout with app:floatingMenu or app:floatingCustomView

#####4. Attach the FAB to the FloatingToolbar to automatically start the transition on click event:

mFloatingToolbar.attachFab(fab);

5. Set a click listener

mFloatingToolbar.setClickListener(new FloatingToolbar.ItemClickListener() {
            @Override
            public void onItemClick(MenuItem item) {
                
            }

            @Override
            public void onItemLongClick(MenuItem item) {

            }
        });

6. (Optional) Attach a RecyclerView to hide the FloatingToolbar on scroll:

mFloatingToolbar.attachRecyclerView(recyclerView);

7 . (Optional) Use show() and hide() to trigger the transition anytime:

mFloatingToolbar.show();
mFloatingToolbar.hide();
