在Android注释中继承

Question

使用AndroidAnnotations时，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;
}

我还有一个名为MainActivity的儿童活动：

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

    @ViewById
    ImageButton btnTabHome;
}

当我构建项目时出现以下错误：

****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()

如果我从BaseActivity_继承，则会收到以下错误：

****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，我应该只改变字段的修饰符。
