  • First Method:

    In res/values-v21/styles.xml,

    <style name="AppTheme" parent="android:Theme.Material.Light.DarkActionBar">
        <item name="android:colorAccent">@color/custom_theme_color</item>
        <item name="android:colorPrimaryDark">@color/custom_theme_color</item>
        <item name="android:colorPrimary">@color/custom_theme_color</item>
    </style>
    

    First Method : Pink color

    First Method: Green color

    The above code is simple and working well. In Android studio, it could be able to change from default sky blue color to any other colors like pink or green!

    Second Method:

    Create 3 files under xml ie. res/xml such as checked.xml, unchecked.xml and custom_checkbox.xml

    checked.xml

    <shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="2px" android:color="#FF00FF" />
    <size android:height="20dp" android:width="20dp"/>
    </shape>
    

    unchecked.xml

    <shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="2px" android:color="#ffc0c0c0" />
    <size android:height="20dp" android:width="20dp"/>
    </shape>
    

    custom_checkbox.xml

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" 
          android:drawable="@xml/checked" /> 
    <item android:state_pressed="true"
          android:drawable="@xml/checked" /> 
    <item android:drawable="@xml/unchecked" /> 
    </selector>
    

    From above second method, it (customized file) also could be able to create any shapes and colors based on our requirements. Even we can be able to customize the style, shapes and themes for a widget by using 2nd method.

    Above two methods are working fine for me!

    Also in from v23 with AppCompat you can use android.support.v7.widget.AppCompatCheckBox and change CheckBox style like this:

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

    where in style.xml:

    <style name="CheckBox" parent="Widget.AppCompat.CompoundButton.CheckBox">
        <item name="colorControlNormal">@color/checkbox_normal</item> <!-- border color -->
        <item name="colorControlActivated">@color/checkbox_activated</item> <!-- fill color -->
        <item name="colorControlHighlight">@color/checkbox_highlight</item> <!-- animation color -->
    </style>
