Android: Resolving Checkbox Listener Issue

Listeners are essential for user interaction with UI components in Android applications. When it comes to CheckBoxes, implementing a listener can be tricky due to a potential mismatch between the expected and actual listener type.

In your case, you encountered an issue with your checkbox listener code that was intended for a RadioGroup. The solution lies in using the correct listener type for a CheckBox.

To address this issue, you should replace the following code:

<code class="java">satView.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    // Handler code
});</code>

with the following:

<code class="java">satView.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        // Handler code
    }
});</code>

The CompoundButton.OnCheckedChangeListener is the appropriate listener type for CheckBoxes. It provides the necessary buttonView and isChecked parameters for handling the check state changes.

With this modification, your code will correctly handle CheckBox check events. Remember, it's important to use the appropriate listener types for different UI components to avoid compiler errors and ensure proper functionality.
