Android快速开发工具：AndroidAnnotations:

github 地址：https://github.com/excilys/androidannotations
目标：
--加快安卓开发
--减少重复代码
--使开发者有更多的事件去思考核心业务代码
实现：
基于Java的注解原理，开发者直接使用注解展示他们的意图，然后AndroidAnnotations会自动帮我们生成代码，使得很多重复冗余的代码只需要一行代码就解决掉。
特征：
--1.依赖注入: inject(注解) views, extras, system services, resources, ...
--2.简化的线程模型:annotate your methods so that they execute on the UI thread or on a background thread.
--3.事件绑定:annotate methods to handle events on views, no more ugly anonymous listener classes!
--4.REST client:REST client: create a client interface, AndroidAnnotations generates the implementation
--5.AndroidAnnotations 这个工具比较小，低于150kb

Code Example：

==================================================

@EActivity(R.layout.translate) // Sets content view to R.layout.translate
public class TranslateActivity extends Activity {

@ViewById // Injects R.id.textInput
EditText textInput;

@ViewById(R.id.myTextView) // Injects R.id.myTextView
TextView result;

@AnimationRes // Injects android.R.anim.fade_in
Animation fadeIn;

@Click // When R.id.doTranslate button is clicked 
void doTranslate() {
     translateInBackground(textInput.getText().toString());
}

@Background // Executed in a background thread
void translateInBackground(String textToTranslate) {
     String translatedText = callGoogleTranslate(textToTranslate);
     showResult(translatedText);
}

@UiThread // Executed in the ui thread
void showResult(String translatedText) {
     result.setText(translatedText);
     result.startAnimation(fadeIn);
}

// [...
