MutativeFab

Dependency

Step 1: Add Jitpack repository in your root build.gradle file (not your module build.gradle file):

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

Step 2: Add dependency to your module's build.gradle file:

dependencies {
    compile 'com.github.aniketbhoite:MutativeFab:1.0.8'
}

Usage

Add floating text button to your layout file like this:

    <com.aniket.mutativefloatingactionbutton.MutativeFab
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:fabIcon="@drawable/ic_location"
        app:fabText="relocate"
        android:layout_alignParentBottom="true"
        app:fabBackgroundColor="@android:color/white"
        app:fabTextColor="@color/colorPrimary"
        android:layout_alignParentEnd="true"/>

In Java or Kotlin

            mFab.setFabText("start chat");
            mFab.setFabTextColor(ContextCompat.getColor(context, R.color.textColor));
            mFab.setFabIcon(R.drawable.ic_chat);
            mFab.setFabBackgroundColor(ContextCompat.getColor(context, android.R.color.holo_blue_dark));
            mFab.setFabTextVisibility(View.VISIBLE);//or View.GONE only
            //to get TextView visibility
            mFab.getFabTextVisibility();//returns Int
            mFab.setFabTypeface(typeface);//to change text font
            
            //in kotlin use can directly access fabText visibility by
            mFab.fabTextVisibility = View.VISIBLE 

If your project do not have kotlin support follow these steps

Step 1: Add Jitpack kotlin gradle plugin in your root build.gradle file (not your module build.gradle file):

    buildscript {
    //this
    ext.kotlin_version = '1.2.41'
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
    dependencies {
        ...
        //and this line
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }

Step 2: Apply plugins to your module's build.gradle file:

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'
