C＃无法解析OnClickListener无法解析符号视图

Question

首先出现了一个错误，我无法解析onclicklistener，现在这个视图无法解决错误！

这是我正在编码的内容。 （查看视图）有什么问题？

public class MainActivity extends AppCompatActivity {

    private EditText UserName;
    private EditText Password;
    private Button Login;
    private TextView CopyRights;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        UserName = (EditText)findViewById(R.id.LogUsername);
        Password = (EditText)findViewById(R.id.LoginPasswprd);
        Login = (Button)findViewById(R.id.LoginButton);
        CopyRights = (TextView)findViewById(R.id.LoginAppInfo);

        Login.setOnClickListener(new View.OnClickListener){

                    public void OnClick(View view){


            }
        });
    }


    private void validate(String name, String pass){

        if( (name.isEmpty() ) || (pass.isEmpty() )){
            Intent intent = new Intent(MainActivity.this, ErrActivity.class);
            startActivity(intent);
        }else if( ( name == "Admin") || (pass == "12345")){
            Intent intent = new Intent(MainActivity.this, AdmActivity.class);
            startActivity(intent);
        }else{
            Intent intent = new Intent(MainActivity.this, UserActivity.class);
            startActivity(intent);
        }
    }
}
