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 extends Activity {   } @fragment

示例：

? 1 2 3 <pre class = "brush:java;" > @EFragment (R.layout.my_fragment_layout) public class MyFragment extends Fragment { }</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 extends Activity {      @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    public void 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

? 1 2 3 4 5 6 7 8 9 10 11 12 13 @EView public class CustomButton extends Button {            @App          MyApplication application;            @StringRes          String someStringResource;        public CustomButton(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

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 @EViewGroup (R.layout.title_with_subtitle) public class TitleWithSubtitle extends RelativeLayout {        @ViewById      protected TextView title, subtitle;        public TitleWithSubtitle(Context context, AttributeSet attrs) {          super (context, attrs);      }        public void 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 extends Application {   }

Activity中使用： ? 1 2 3 4 5 6 7 @EActivity public class MyActivity extends Activity {      @App    MyApplication application;   } @EService ? 1 2 3 4 @EService public class MyService extends Service {   } 跳转service： ? 1 MyService_.intent(getApplication()).start(); 停止service： ? 1 MyService_.intent(getApplication()).stop(); @EReceiver ? 1 2 3 4 @EReceiver public class MyReceiver extends BroadcastReceiver {   } @Receiver可以替代声明BroadcastReceiver ? 1 2 3 4 5 6 7 8 9 @EActivity public class MyActivity extends Activity {      @Receiver (actions = "org.androidannotations.ACTION_1" )    protected void onAction1() {      }   } @EProvider ? 1 2 3 4 @EProvider public class MyContentProvider extends ContentProvider {   } @ViewById ? 1 2 3 4 5 6 7 8 9 10 @EActivity public class MyActivity extends Activity {      // Injects R.id.myEditText，变量名称必须和布局的id名称一致    @ViewById    EditText myEditText;      @ViewById (R.id.myTextView)    TextView textView; } @AfterViews ? 1 2 3 4 5 6 7 8 @EActivity (R.layout.main) public class MyActivity extends Activity {        @ViewById      TextView myTextView;        @AfterViews      void updateTextWithDate() {<pre class = "brush:java;" > //一定要在这里进行view的一些设置，不要在oncreate()中设置，因为oncreate()在执行时 view还没有注入</pre>        myTextView.setText("Date: " + new Date());    }[...] @StringRes ? 1 2 3 4 5 6 7 8 9 10 @EActivity public class MyActivity extends Activity {      @StringRes (R.string.hello)    String myHelloString; //不能设置成私有变量      @StringRes    String hello;   } @ColorRes ? 1 2 3 4 5 6 7 8 9 10 @EActivity public class MyActivity extends Activity {      @ColorRes (R.color.backgroundColor)    int someColor;      @ColorRes    int backgroundColor;   } @AnimationRes ? 1 2 3 4 5 6 7 8 9 10 @EActivity public class MyActivity extends Activity {      @AnimationRes (R.anim.fadein)    XmlResourceParser xmlResAnim;      @AnimationRes    Animation fadein;   } @DimensionRes ? 1 2 3 4 5 6 7 8 9 10 @EActivity public class MyActivity extends Activity {      @DimensionRes (R.dimen.fontsize)    float fontSizeDimension;      @DimensionRes    float fontsize;   } @DImensionPixelOffsetRes ? 1 2 3 4 5 6 7 8 9 10 @EActivity public class MyActivity extends Activity {      @DimensionPixelOffsetRes (R.string.fontsize)    int fontSizeDimension;      @DimensionPixelOffsetRes    int fontsize;   } @DimensionPixelSizeRes ? 1 2 3 4 5 6 7 8 9 10 @EActivity public class MyActivity extends Activity {      @DimensionPixelSizeRes (R.string.fontsize)    int fontSizeDimension;      @DimensionPixelSizeRes    int fontsize;   } 其他的Res： @BooleanRes@ColorStateListRes@DrawableRes@IntArrayRes@IntegerRes@LayoutRes@MovieRes@TextRes@TextArrayRes@StringArrayRes @Extra ? 1 2 3 4 5 6 7 8 9 10 @EActivity public class MyActivity extends Activity {      @Extra ( "myStringExtra" )    String myMessage;      @Extra ( "myDateExtra" )    Date myDateExtraWithDefaultValue = new Date();   } 或者： ? 1 2 3 4 5 6 7 @EActivity public class MyActivity extends Activity {      // The name of the extra will be "myMessage"，名字必须一致    @Extra    String myMessage; } 传值： ? 1 MyActivity_.intent().myMessage( "hello" ).start() ; @SystemService ? 1 2 3 4 5 6 @EActivity public class MyActivity extends Activity { //    @SystemService    NotificationManager notificationManager;   } @HtmlRes ? 1 2 3 4 5 6 7 8 9 10 11 12 @EActivity public class MyActivity extends Activity {      // Injects R.string.hello_html    @HtmlRes (R.string.hello_html)    Spanned myHelloString;      // Also injects R.string.hello_html    @HtmlRes    CharSequence helloHtml;   } @FromHtml ?

1 2 3 4 5 6 7 8 9 10 public class MyActivity extends Activity { //等同于 Activity.onRetainNonConfigurationInstance()      @NonConfigurationInstance    Bitmap someBitmap;      @NonConfigurationInstance    @Bean    MyBackgroundTask myBackgroundTask;   } @HttpsClient ? 1 2 <pre class = "brush:java;" > @HttpsClient HttpClient httpsClient;</pre> 示例： ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 @EActivity public class MyActivity extends Activity {        @HttpsClient (trustStore=R.raw.cacerts,          trustStorePwd= "changeit" ,          hostnameVerif= true )      HttpClient httpsClient;        @AfterInject      @Background      public void securedRequest() {          try {              HttpGet httpget = new HttpGet( "https://www.verisign.com/" );              HttpResponse response = httpsClient.execute(httpget);              doSomethingWithResponse(response);          } catch (Exception e) {              e.printStackTrace();          }      }        @UiThread      public void doSomethingWithResponse(HttpResponse resp) {          Toast.makeText( this , "HTTP status " + resp.getStatusLine().getStatusCode(), Toast.LENGTH_LONG).show();      } } @FragmentArg ?
