The @EActivity annotation indicates that an activity will be enhanced by AndroidAnnotations. Its value parameter must be a valid layout id, that will be used as the Content View for the activity.

为一个activity加了 @EActivity 注解后，则表示该activity被 AndroidAnnotations 加强了。它的参数值必须是一个合法 layout id 的，这个 layout id 被当作该activity的 Content View 使用。

You can leave the value parameter empty, which means that no content view will be set. You will probably want to set the content view yourself in the onCreate() method, before the binding is done.

你可以不写参数值，这意味着不设置content view。你也可能想要在绑定动作结束前，自己在 onCreate() 方法中设置content view。

@EActivity(R.layout.main)
public class MyActivity extends Activity {
        }

@EActivity
public class MyListActivity extends ListActivity {
        @Overridepublic void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);setContentView(R.layout.main);}}
