我的自定义视图中出现以下错误

e: [kapt] An exception occurred: android.databinding.tool.util.LoggedErrorException: Found data binding errors.
****/ data binding error ****msg:Could not find event 'isCheckedAttrChanged' on View type 'com.playground.components.SquareCheckBox' file:/Volumes/Data/Work/Amira_Playground/Playground/app/src/main/res/layout/recycler_view_basic_information_settings_item.xml loc:47:8 - 60:50 ****\ data binding error ****
