FAB Color for backgroundTint not changing in Gingerbread version devices

Question

I am facing an issue while changing backgroundTint color in xml for FAB, that the color has not assigned for devices with Gingerbread versions. I am really confused and don't know why it is behaving weird. I am completely stuck with this issue with a couple of hours triggering out the solution but I couldn't. Kindly help me with your tips and suggestions to resolve my issue. I am posting my code and screen shot of the issue for your reference. Thanks in advance.

include_fab.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|right"
    android:layout_marginBottom="20dp"
    android:layout_marginRight="20dp"
    app:backgroundTint="#FF0000"
    app:borderWidth="0dp"
    app:elevation="5dp"
    app:fabSize="normal"/>

Design support library in my gradle

compile 'com.android.support:design:23.0.0'

Note: I am getting exact output of my requirement above GingerBread devices. Problem arises with GingerBread alone.

I'm having similar problems, it also causes crashes. Are you using Genymotion? – Ambience

Using both but i didnt try this in genymotion. – Lamoree

I dont have genymotion gingerbread versions, but it is working fine with latest versions in genymotion – Lamoree

I only noticed this on gingerbread Genymotion, wondering if this might be a Genymotion issue. – Ambience

no yar in device also this issue is replicating. – Lamoree

It seems like this issue was not present in support design v22 – Ambience

yes of course. you are right. It is really a critical one that should be sorted out because still GingerBread users are in practice. Around 20 percent of the people overall uses GingerBread. – Lamoree

I have this same issue on hardware (T-Mobile HTC myTouch 4g running 2.3) and on a normal 2.3 emulator, so don't blame genymotion. I think it may be a generic gingerbread problem. – Vue

@Vue yes u r right. It is not genymotion issue. I recently tested with Samsung-S2 and same problem arises. – Lamoree

Answer 1

It may work

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        FloatingActionButton v = (FloatingActionButton) findViewById(R.id.fab);
        ColorStateList csl = new ColorStateList(new int[][]{new int[0]}, new int[]{0xffff0000});
        v.setSupportBackgroundTintList(csl);
    }
