material checkbox style after customize

Question

My customized checkbox (MyCheckbox) has extended from androidx.appcompat.widget.AppCompatCheckBox, but the default styles don\'t apply to it.

You can also apply the style to the single checkbox using:

As alternative you can also use the android:theme in the layout, but it doesn't work globally.

Just a note.
The colorTint selector is defined programmatically in the MaterialCheckBox code. You can also define a custom colorTint selector adding the buttonTint attribute in your custom style. In this case the colors defined above are ignored.
