Android 最火的快速开发框架androidannotations配置详解文章中有eclipse配置步骤，Android 最火快速开发框架AndroidAnnotations简介文章中的简单介绍，本篇注重讲解AndroidAnnotations中注解方法的使用。

@EActivity

示例：

?
1
2
3
4
@EActivity(R.layout.main)
public class MyActivity extendsActivity {
 
}
@fragment

示例：

?
1
2
3
<pre class="brush:java;">@EFragment(R.layout.my_fragment_layout)
public class MyFragment extendsFragment {
}</pre>
注册：
?
1
<fragment android:id="@+id/myFragment"android:name="com.company.MyFragment_"android:layout_width="fill_parent"android:layout_height="fill_parent"></fragment>

创建：

?
1
MyFragment fragment =new MyFragment_();

普通类：

?
1
2
3
4
@EBean
public class MyClass {
 
}


注意：这个类必须仅仅只能有一个构造函数，参数最多有一个context。

Activity中使用：

?
1
2
3
4
5
6
7
@EActivity
public class MyActivity extendsActivity {
 
  @Bean
  MyOtherClass myOtherClass;
 
}

也可以用来声明接口：

?
1
2
@Bean(MyImplementation.class)
    MyInterface myInterface;

在普通类中还可以注入根环境:

?
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
@EBean
public class MyClass {
 
  @RootContext
  Context context;
 
  // Only injected if the root context is an activity
  @RootContext
  Activity activity;
 
  // Only injected if the root context is a service
  @RootContext
  Service service;
 
  // Only injected if the root context is an instance of MyActivity
  @RootContext
  MyActivity myActivity;
 
}

如果想在类创建时期做一些操作可以：

?
1
2
3
4
@AfterInject
  publicvoid doSomethingAfterInjection() {
    // notificationManager and dependency are set
  }

单例类需要如下声明：

?
1
2
3
4
@EBean(scope = Scope.Singleton)
public class MySingleton {
 
}

注意：在单例类里面不可以注入view和事件绑定，因为单例的生命周期比Activity和Service的要长，以免发生内存溢出。

@EView

?

@EView
public class CustomButton extendsButton {

        MyApplication application;
 
        @StringRes
        String someStringResource;
 
    publicCustomButton(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
}


注册：

?
1
<com.androidannotations.view.custombutton_ android:layout_width="match_parent"android:layout_height="wrap_content"></com.androidannotations.view.custombutton_>

创建：

?
1
CustomButton button = CustomButton_.build(context);


@EViewGroup

?

@EViewGroup(R.layout.title_with_subtitle)
public class TitleWithSubtitle extendsRelativeLayout {
 
    @ViewById
    protectedTextView title, subtitle;
 
    publicTitleWithSubtitle(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
 
    publicvoid setTexts(String titleText, String subTitleText) {
        title.setText(titleText);
        subtitle.setText(subTitleText);
    }
 
}

注册：

?
1
<com.androidannotations.viewgroup.titlewithsubtitle_ android:id="@+id/firstTitle"android:layout_width="match_parent"android:layout_height="wrap_content"></com.androidannotations.viewgroup.titlewithsubtitle_>

@EApplication

?
1
2
3
4
@EApplication
public class MyApplication extendsApplication {
 
}

Activity中使用：
?

@EActivity
public class MyActivity extendsActivity {
 
  @App
  MyApplication application;

@EService
?
1
2
3
4
@EService
public class MyService extendsService {
 
}

跳转service：
?
1
MyService_.intent(getApplication()).start();

停止service：
?
1
MyService_.intent(getApplication()).stop();

@EReceiver
?
1
2
