业务逻辑

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();

	// ...

}

我认为依照这个思路写。代码会比較清爽。

兴许说原因，先回宿舍了。
