简介

androidannotations在开发中的代码规范思考：（MVC思考）时间太紧，先贴代码：

Activity的代码：

package edu.njupt.zhb.main;

import org.androidannotations.annotations.AfterViews;
import org.androidannotations.annotations.Bean;
import org.androidannotations.annotations.EActivity;

import android.app.Activity;

/**
 * @author Zheng Haibo
 * @web  http://www.mobctrl.net
 */
@EActivity(R.layout.main)
public class MainActivity extends Activity {

  @Bean
  MainActions mainActions;

  @AfterViews
  void afterViews() {
    doSomething();
  }

  private void doSomething() {
    mainActions.doActionsInThread(20, new UiCallback() {

      @Override
      public void onBackgroundEnd() {
        // TODO Auto-generated method stub
        // write the code
        System.out.println("the background thread end...");
      }
    });
  }
}

业务逻辑

MainActions

package edu.njupt.zhb.main;

import org.androidannotations.annotations.Background;
import org.androidannotations.annotations.EBean;
import org.androidannotations.annotations.RootContext;
import org.androidannotations.annotations.UiThread;

import android.content.Context;
import android.widget.Toast;
/**
 * @author Zheng Haibo
 * @web  http://www.mobctrl.net
 */
@EBean
public class MainActions {

  @RootContext
  Context context;

  @Background
  void doActionsInThread(int params, UiCallback uiCallback) {
    // database，net，file，sp ...
    int result = 0;
    for (int i = 0; i < params; i++) {
      result = result + i;
      try {
        Thread.sleep(200);
      } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      }
      System.out.println("test the thread is run in the background...");
    }
    runInUiThread(result, uiCallback);
  }

  @UiThread
  void runInUiThread(int result, UiCallback uiCallback) {
    Toast.makeText(context, result + ", just a test", Toast.LENGTH_SHORT)
        .show();
    System.out.println("you can write the ui code ...");
    uiCallback.onBackgroundEnd();
  }
}

回调接口

package edu.njupt.zhb.main;

/**
 * @author Zheng Haibo
 * @web http://www.mobctrl.net
 */
public interface UiCallback {
  public void onBackgroundEnd();
  // ...
}
