Floating Action Button with square shape

Solution 1
Use
app:backgroundTint="@android:color/holo_green_dark"
(for example) to set color of fab. Result below. Taken from this -tested- code snippet.
Also edit : "strange green color" should come from your accent color. That's the color fab takes by default.
Solution 2
Use this code in your xml
app:borderWidth="0dp"
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_add"
android:layout_marginRight="20dp"
app:fabSize="normal"
android:elevation="@dimen/fab_elevation"
android:background="#000000"
app:borderWidth="0dp"
android:stateListAnimator="@animator/fab_anim"
android:layout_gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true" />

Jonathan I almost 2 years
When I set a color to my fab, it looks like so:
My layout xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity$PlaceholderFragment"> <android.support.design.widget.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_add" android:layout_marginRight="20dp" app:fabSize="normal" android:elevation="@dimen/fab_elevation" android:background="#000000" android:stateListAnimator="@animator/fab_anim" android:layout_gravity="center_horizontal" android:layout_alignParentBottom="true" android:layout_alignParentEnd="true" />
Also the color doesn't change. Can anyone help me in understanding what I am doing wrong?
I also tried with a
@color
link but it crashed, with the background of a drawable(ex. android:background="@drawable/fab_background")
nothing happens.Here is the drawable
fab_background.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android"> <item> <ripple android:color="@color/fab_color_1_muted"> <item> <shape> <solid android:color="@color/fab_color_1" /> </shape> </item> </ripple> </item>

SMKS over 8 yearsUsing the code that is linked worked for me. Thanks! That green color is super cool.
