Set background color of unchecked checkbox Android

Do it like this-

In your layout file-

<android.support.v7.widget.AppCompatCheckBox
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:theme="@style/CheckboxStyle"/>

and in your style.xml file

<style name="CheckboxStyle" parent="AppTheme">
    <item name="colorAccent">@color/colorAccent</item>
</style>

Or you can change both the checked and unchecked color like this-

<style name="CheckboxStyle" parent="AppTheme">
    <item name="colorAccent">@color/colorAccent</item>  // for checked 
    <item name="android:textColorSecondary">@color/colorSecondary</item>  // for unchecked
</style>

change colorAccent and colorSecondary with your required colors.

hope it will help you..

I know it is answered but someone may find this useful, another way to achieve this is by using color state list, declare a color state list for the checkbox in an xml file

checkbox_state_list.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:color="@color/orange" android:state_checked="true"/>
   <item android:color="@color/black" android:state_checked="false"/>
</selector>

Now use this state list as

<android.support.v7.widget.AppCompatCheckBox
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:buttonTint="@color/checkbox_state_list"/>

You have to use CheckBox style like this:

in xml style

 <style name="MyCheckBox" parent="Theme.AppCompat.Light">
        <item name="colorControlNormal">@color/white</item>
        <item name="colorControlActivated">@color/white</item>
 </style>

in xml layout .

<CheckBox
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    style="@style/MyCheckBox"
    ...
