DataBinderMapperImpl 找不到 ActivityLoginBinding 的符号

Question

我创建了登录活动。 但无法生成登录绑定文件。"error 在 DataBinderMapperImpl 中找不到符号 ActivityLoginBindingImpl。我可以添加什么？它应该以耳形方式生成自己。 登录活动：基本活动中的某些操作

public class LoginActivity extends BaseActivity<ActivityLoginBinding, LoginViewModel> implements View.OnClickListener, TextView.OnEditorActionListener {
@Inject
LoginViewModel loginViewModel;
ActivityLoginBinding activityLoginBinding = DataBindingUtil.setContentView(this, R.layout.activity_login);

@Override
public int getBindingVariable() {
return BR.viewModelLogin;
}
@Override
public int getLayoutId() {
return R.layout.activity_login;
}
@Override
public LoginViewModel getViewModel() {
return  loginViewModel;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
activityLoginBinding = getViewDataBinding();
loginViewModel.setNavigator(this);
activityLoginBinding.btnLogin.setOnClickListener(this);

}
@Override
public void handleError(Throwable throwable) {
// handle error
}
@Override
public void onClick(View v) {
activityLoginBinding.tvTranData.setText("");
}
private void getKeyboardGo(){
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
}
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_GO) {
getKeyboardGo();
return true;
}
return false;
}
}

LoginViewModel：我创建了LoginUser模型..................

public class LoginViewModel extends BaseViewModel<BaseNavigator> {
public MutableLiveData<String> mTCKN =new MutableLiveData<>();
public MutableLiveData<String > mPassword =new MutableLiveData<>();
private MutableLiveData<LoginUser> userMutableLiveData;
public MutableLiveData<LoginUser> getUser(){
if (userMutableLiveData == null) {
userMutableLiveData = new MutableLiveData<>();
}
return userMutableLiveData;
}
public void onClick(View view) {
LoginUser loginUser = new LoginUser(mTCKN.getValue(), mPassword.getValue());
userMutableLiveData.setValue(loginUser);
}
}

问题出在布局的按钮上。您尝试访问LoginViewModel方法作为static。检查以下内容：

用

android:onClick="@{(v) -> viewModelLogin.onClick(v)}"

而不是

android:onClick="@{(v) -> LoginViewModel.onClick(v)}"
