Android注释中的继承

在使用

AndroidAnnotations

时，我在从基类继承时遇到问题。我有一个名为

BaseActivity

的基本活动：

@EActivity
public abstract class BaseActivity extends AppCompatActivity {

    @ViewById
    Toolbar toolbar;

    @ViewById(R.id.drawer_layout)
    DrawerLayout drawerLayout;

    @ViewById(R.id.nav_view)
    NavigationView navView;
}

@EActivity(R.layout.activity_main)
public class MainActivity extends BaseActivity {

    @ViewById
    ImageButton btnTabHome;
}

我还有一个名为

MainActivity

的子活动：

@EActivity
public abstract class BaseActivity extends AppCompatActivity {

    @ViewById
    Toolbar toolbar;

    @ViewById(R.id.drawer_layout)
    DrawerLayout drawerLayout;

    @ViewById(R.id.nav_view)
    NavigationView navView;
}

@EActivity(R.layout.activity_main)
public class MainActivity extends BaseActivity {

    @ViewById
    ImageButton btnTabHome;
}

在生成项目时，会出现以下错误：

****MyProjectBuildPath****\MainActivity_.java
Error:(82, 13) error: toolbar is not public in BaseActivity; cannot be accessed from outside package

Error:(83, 13) error: drawerLayout is not public in BaseActivity; cannot be accessed from outside package

Error:(84, 13) error: navView is not public in BaseActivity; cannot be accessed from outside package

Error:(90, 9) error: cannot find symbol method initBaseViews()

****MyProjectBuildPath****\MainActivity.java
Error:(19, 35) error: cannot find symbol class BaseActivity_

Error:(17, 1) error: org.androidannotations.annotations.EActivity can only be used on an element that extends android.app.Activity

Warning:(19, 8) Element packagename.MainActivity invalidated by EActivityHandler

如果我继承自

BaseActivity\uuu

，则会出现以下错误：

****MyProjectBuildPath****\MainActivity_.java
Error:(82, 13) error: toolbar is not public in BaseActivity; cannot be accessed from outside package

Error:(83, 13) error: drawerLayout is not public in BaseActivity; cannot be accessed from outside package

Error:(84, 13) error: navView is not public in BaseActivity; cannot be accessed from outside package

Error:(90, 9) error: cannot find symbol method initBaseViews()

****MyProjectBuildPath****\MainActivity.java
Error:(19, 35) error: cannot find symbol class BaseActivity_

Error:(17, 1) error: org.androidannotations.annotations.EActivity can only be used on an element that extends android.app.Activity

Warning:(19, 8) Element packagename.MainActivity invalidated by EActivityHandler

我的错误在哪里？

关于我应该只更改字段的修饰符。

您是否尝试将BaseActivity中的变量范围声明为public，然后在MainActivty类中继承BaseActivity？
