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:1.2.0'

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

|
|->FABToolbarLayout
	|
	|-> Some container (that is, or extends RelativeLayout)
	|	|
	|	|-> Your FAB (or other view that extends ImageView)
	|	
	|-> Your Toolbar (view that extends ViewGroup)
		|
		|-> Your elements
		...

Starting from version 1.1.0 views do NOT have to be assigned a static ID. Instead try referencing them in XML attributes in FABToolbarLayout, as shown below.

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:horizontalMargin="30dp"
	app:verticalMargin="30dp"
	app:fadeInFraction="0.2"
	app:fabId="@+id/fabtoolbar_fab"
	app:containerId="@+id/fabtoolbar_container"
	app:fabToolbarId="@+id/fabtoolbar_toolbar">

	...
	
	<RelativeLayout
		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"/>

	</RelativeLayout>

	<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>
