我的项目中有3个模块:common
,admin
和client
。
第一个是带有抽象LoginActivity
的Android库,其他模块(应用程序)扩展自。
LoginActivity
有自己的布局,所有方法都已实现,但只有一个:tryLogin(user, password)
导航到主要活动,每个应用都有不同。
我已关注official documentation但是当我点击signIn
按钮时,未调用OnClickListener。此外,所有绑定视图都为空...
这是来自admin
的所有相关代码(两个模块几乎相同)

@Override

setContentView(R.layout.activity_login);
ButterKnife.bind(this);
}
@OnClick(R2.id.login_sign_in)

String user = this.user.toString();
String password = this.password.getText().toString();
/* Fields validations ... */
tryLogin(user, password);

AdminLoginActivity(admin)
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import xxx.activity.LoginActivity;
import butterknife.ButterKnife;
public class AdminLoginActivity extends LoginActivity {
@Override
protected void tryLogin(String user, String password) {
// This is never called!!
Toast.makeText(this, "Login in...", Toast.LENGTH_SHORT).show();
}
}
应用程序不会崩溃或任何事情,它什么都不做。
我做错了什么?
答案 0 :(得分:0)
我的猜测是代码导入了错误的R文件。
要验证这一点,您可以查看在所讨论的库模块的build / generated / source中自动构建的R文件,并查看是否包含您要查找的ID。生成了几个R文件。找到具有您要查找的ID的那个,并确保它与您的R导入名称空间匹配。
