Android應用開發框架：Android Annotations

Android Annotations是一個開源的框架，用于加速 Android應用的開發，可以讓你把重點放在功能的實現上，簡化了代碼，提升了可維護性。

特性：

• 依賴注入: inject views, extras, system services, resources, ...
• 簡化的線程模型: annotate your methods so that they execute on the UI thread or on a background thread.
• Event 綁定: annotate methods to handle events on views, no more ugly anonymous listener classes!
• REST 客戶端: create a client interface, AndroidAnnotations generates the implementation.
• AndroidAnnotations provide those good things and even more for less than 50kb, without any runtime perf impact!

@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);
    }

    // [...]
}
