Custom CheckBox in Android Studio

A CheckBox widget allows the user to select one or more options from a set of options. It is widely used in Android apps to implement features such as selection of multiple items, marking items as done, and many more. In this tutorial, we will learn how to create a Custom CheckBox in Android Studio.

Syntax

<CheckBox
    android:id="@+id/id_checkbox"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="CheckBox Text"
    android:button="@drawable/custom_checkbox" />

Example

Here's an example of a custom checkbox in Android Studio.

<CheckBox
    android:id="@+id/checkbox_custom"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Custom CheckBox"
    android:button="@drawable/custom_checkbox"/>

Output

Explanation

In the above example, we use android:button attribute to set the custom drawable for the CheckBox. By default, CheckBox component has a default style but using android:button we can modify it as per our requirement.

We can create a custom drawable for the CheckBox by creating a new XML file under the drawable folder. Here's an example of a custom checkbox drawable.

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

In the above code, we create two drawables for checked and unchecked states of the custom checkbox. We use the state_checked attribute to define the different drawables for different states of the CheckBox.
