Android CheckBox class is the subclass of CompoundButton class. It is generally used in a place where user can select one or more than choices from a given list of choices. For example, selecting hobbies.

Using the input tag is the simplest approach to constructing a checkbox in HTML. As you can see from the example code, we have selected "checkbox" as the input type checkbox in HTML. We can give the checkbox a name using the name attribute, and describe the value it stores using the value attribute.

Android CheckBox Example <? xml version="1.0" encoding="utf-8"?> android:layout_width="match_parent" android:layout_height="match_parent" tools:context="example.javatpoint.com.checkbox.MainActivity"> <CheckBox. android:id="@+id/checkBox" android:layout_width="wrap_content" android:layout_height="wrap_content"

To create each checkbox option, create a CheckBox in your layout. Because a set of checkbox options lets the user select multiple items, each checkbox is managed separately, and you must register a click listener for each one.

The validation of the checkbox in javascript can be done using the checked property of the checkbox element. This property returns true when the checkbox is selected. The addEventListener() method can be used to apply the change event to the checkbox to validate whenever the user interacts with the checkbox.

By default, the android CheckBox will be in the OFF (Unchecked) state. We can change the default state of CheckBox by using android:checked attribute. In case, if we want to change the state of CheckBox to ON (Checked), then we need to set android:checked = “true” in our XML layout file.

Android CheckBox Example <? xml version="1.0" encoding="utf-8"?> android:layout_width="match_parent" android:layout_height="match_parent" tools:context="example.javatpoint.com.checkbox.MainActivity"> <CheckBox. android:id="@+id/checkBox" android:layout_width="wrap_content" android:layout_height="wrap_content"

Approach Step 1: Creating a new project. To create a new project in android studio please refer to How to Create/Start a New Project in Android Studio. Step 2: Modifying activity_main.xml. Before a CheckBox can be added dynamically, a layout needs to be defined beforehand to hold the CheckBox.
