How do I properly implement a listener for a CheckBox in Android?

CheckBox Listener in Android

When implementing a listener for a CheckBox in Android, it's essential to address a common issue faced when using the standard OnCheckedChangeListener class.

The standard implementation targets a RadioGroup instead of a CheckBox. To resolve this, utilize the CompoundButton.OnCheckedChangeListener interface instead. Here's a modified code example:

<code class="java">satView.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {

    }
}
);</code>
Copy after login

By utilizing this revised approach, the listener will properly handle changes in the CheckBox's checked state.
