androidannotations的background和UiThread配合使用參考
简单介绍
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(); // ... }
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。
