FABToolbar

An implementation of Google design, with Floating Action Button transforming into toolbar.

Features:

morphing Floating Action Button (or any other view that extends ImageView) into custom toolbar
FAB image fade-out animation
toolbar elements fade-in animation
toolbar elements translation animation

How to use

Import dependency using Gradle:

compile 'com.github.fafaldo:fab-toolbar:1.0.1'

In order to use FABToolbar you need to implement following view hierarchy in your XML layout file:

|
|->FABToolbarLayout
	|
	|-> FABContainer (id: fabtoolbar_container)
	|	|
	|	|-> Your FAB (or other view that extends ImageView; id: fabtoolbar_fab)
	|	
	|-> Your Toolbar (view that extends ViewGroup; id: fabtoolbar_toolbar)
		|
		|-> Your elements
		...

Remember to assign each element a proper ID.

Example implementation:

<com.github.fafaldo.fabtoolbar.widget.FABToolbarLayout
	android:id="@+id/fabtoolbar"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	app:showDuration="600"
	app:hideDuration="200"
	app:rightMargin="30dp"
	app:bottomMargin="30dp"
	app:fadeInFraction="0.2">

	...
	
	<com.github.fafaldo.fabtoolbar.widget.FABContainer
		android:id="@+id/fabtoolbar_container"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:layout_alignParentBottom="true"
		android:layout_alignParentRight="true">

		<android.support.design.widget.FloatingActionButton
			android:id="@+id/fabtoolbar_fab"
			android:layout_width="wrap_content"
			android:layout_height="wrap_content"
			app:fabSize="normal"
			android:src="@drawable/abc_ic_menu_share_mtrl_alpha"/>

	</com.github.fafaldo.fabtoolbar.widget.FABContainer>

	<LinearLayout
		android:id="@+id/fabtoolbar_toolbar"
		android:layout_width="match_parent"
		android:layout_height="70dp"
		android:layout_alignParentBottom="true"
		android:orientation="horizontal">

		<ImageView
			android:id="@+id/one"
			android:layout_width="0dp"
			android:layout_height="match_parent"
			android:layout_weight="1"
			android:scaleType="centerInside"
			android:src="@drawable/test"/>
		...
		
	</LinearLayout>

</com.github.fafaldo.fabtoolbar.widget.FABToolbarLayout>

Toolbar will be automatically opened on FAB click. If you want to do it manually use function

show();

To close toolbar call function

hide();

In case of other problems with implementation see example included in this repository.
