数据绑定不生成某些变量的方法

Question

我在我的项目中实现了数据绑定但是我可以看到什么奇怪的行为，它没有为我在xml中定义的一些变量生成方法。即使我已多次清理和重建我的项目。 但它正在为我的模型类生成方法。

mBinding.setModel(mProfileViewModel); 

我昨天创建的。我真的很困惑发生了什么。如果您有任何想法，请提供帮助。

下面是我的xml。

<?xml version="1.0" encoding="utf-8"?>

以下是我的活动

public class ProfileActivity extends BaseActivity implements LogoutDialog.ILogoutListener {

private ActivityProfileBinding mBinding;
private ProfileViewModel mProfileViewModel;


@Override
protected void onCreatingBase(Bundle savedInstanceState, Intent intent) {
    mBinding = DataBindingUtil.setContentView(this, R.layout.activity_profile);
    mProfileViewModel = ViewModelProviders.of(this, new ProfileViewModelFactory(getApplication())).get(ProfileViewModel.class);

    mProfileViewModel.getLogoutResponse().observe(this, mLogoutObserver);
    mBinding.setModel(mProfileViewModel);
    registerObservers(mProfileViewModel);
    mProfileViewModel.fetchClassRooms();
}


/**
 * Observer listening to the response of Logout API
 */
private Observer<ApiResponse> mLogoutObserver = new Observer<ApiResponse>() {
    @Override
    public void onChanged(ApiResponse classRoomResponses) {

    }
};


@Override
public void onClick(View view) {
}

@Override
public void onYesClicked() {
    mProfileViewModel.doLogout();
}
}

LogoutDialog类

public class LogoutDialog {

public static void showDialog(Context context,final ILogoutListener logoutListner ){
    new AlertDialog.Builder(context)
            .setMessage(context.getResources().getString(R.string.logout_desc))
            .setCancelable(false)
            .setPositiveButton(context.getResources().getString(R.string.yes_text), new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    logoutListner.onYesClicked();
                }
            })
            .setNegativeButton(context.getResources().getString(R.string.no_text), null)
            .show();

}

public interface ILogoutListener {
    void onYesClicked();
}

}
