Material Design FABToolbar

Overview

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>

show();

To close toolbar call method

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

Issue on Sony Devices with FabToolbar

Having an issue with Sony devices in particular (Z3 & Z3 Compact) where the icon of the fab is not disappearing from the background when expanded. It doesn't happen on a Galaxy Nexus running JellyBean or Nexus 5 running Marshmallow. The video below demonstrates the issue... http://clients.intohand.com/demo/XperiaProblem.mov

Unable to listen to fab click

Trying to listen to click event on fabtoolbar_fab (FloatingActionButton) to call fabToolbar show() only when some condition is met.

Problem: My onClickListener isn't getting called when Fab is clicked.

findViewById(R.id.fabtoolbar_fab).setOnClickListener(new View.OnClickListener() {
    @Override public void onClick(View view) {
         Log.d("mlog", "My Click"); // Doesn't trigger
         if ( isLoaded() ) { 
             fabToolbar.show();
         } else {
             showSnackBar("Fetching newsfeed...");
         }
     }
});

Add check SDK version

in FABToolbarLayout.java need add check SDK version in 185 line for support Android SDK version 15:

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                                fabContainer.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                            } else {
                                fabContainer.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                            }

Why to limit it to API 16 when you can make for earlier APIs?

Hi, you can use if (Build.VERSION.SDK_INT < 16) { fabContainer.getViewTreeObserver().removeGlobalOnLayoutListener(this); fab.setVisibility(VISIBLE); } else { fabContainer.getViewTreeObserver().removeOnGlobalLayoutListener(this); fab.setVisibility(VISIBLE); } to make it compatible for <16 sdk versions.

hide() does not bring floating action button is not at same place

if layout of FloatingActionButton is

android:layout_alignParentTop="true" android:layout_alignParentRight="true"

when we call layout.hide() then toolbar hides but FAB apears too much up. even half is cut by topbar.

BUG: issues FAB that morphs into android.support.v7.widget.Toolbar

Hi,

I set FAB that morphs into android.support.v7.widget.Toolbar:

        <!--android:background="@android:drawable/btn_default"-->

    </android.support.v7.widget.Toolbar>

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

I have two issues:

The fab that morphs into toolbar shows as very small (by factor of 2) see screenshot
After each morph cycle (fab-->toolbar-->fab) the fab moves to left some 5dps and then completely disappears so you can't tap on it.

The cause for this is 50dp size of the spinner. If I set it to 70dp everything works fine.
