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>
