Cannot find a setter for <com.scwang.smart.refresh.footer.ClassicsFooter app:loadingText> that accepts parameter type 'me.hgj.jetpackmvvm.callback.databind.StringObservableField' If a binding adapter provides the setter, check that the adapter is annotat

ed correctly and that the parameter type matches.

To resolve this issue, you need to create a binding adapter that accepts the parameter type 'me.hgj.jetpackmvvm.callback.databind.StringObservableField' for the loadingText attribute of the ClassicsFooter in your XML layout.

Here's an example of how the binding adapter can be implemented:

@BindingAdapter("app:loadingText")
public static void setLoadingText(ClassicsFooter classicsFooter, StringObservableField loadingText) {
    classicsFooter.setLoadingText(loadingText.get());
}

Make sure to annotate the binding adapter method with the `@BindingAdapter` annotation and provide the attribute name as the parameter.

After creating the binding adapter, you should be able to use the loadingText attribute with a StringObservableField in your XML layout without any errors.
