11.菜单界面、详情界面

菜单界面
在MainActivity  的initView方法里
  1. 	// 添加菜单
  2. 		fl_menu=(FrameLayout) findViewById(R.id.fl_menu);
  3. 		MenuHolder holder=new MenuHolder();
  4. 		//登陆的时候数据保存起来了，在到了这里就判断有没有登陆过，这步还没写
  5. 		//holder.setData(data)
  6. 		fl_menu.addView(holder.getContentView());
菜单布局（写上这个属性在小屏幕上能滑，大屏幕上是匹配屏幕）
  1. <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
  2.     android:layout_width="match_parent"
  3.     android:layout_height="match_parent"
  4.     android:fillViewport="true" >
  5. 	<!--ScollView 包裹的孩子 默认高度只能是包裹内容 
  6. 	 android:fillViewport="true"允许孩子是匹配父容器  -->
  7.     <LinearLayout
  8.         android:layout_width="match_parent"
  9.         android:layout_height="match_parent"
  10.         android:orientation="vertical" >
MenuHolder 
  1. public class MenuHolder extends BaseHolder<UserInfo> implements OnClickListener {
  2. 	@ViewInject(R.id.photo_layout)
  3. 	private RelativeLayout photo_layout;
  4. 	@ViewInject(R.id.image_photo)
  5. 	private ImageView image_photo;
  6. 	@ViewInject(R.id.user_name)
  7. 	private TextView user_name;
  8. 	@ViewInject(R.id.user_email)
  9. 	private TextView user_email;
  10. 	@Override
  11. 	public View initView() {
  12. 		View view=UiUtils.inflate(R.layout.menu_holder);
  13. 		ViewUtils.inject(this, view);
  14. 		photo_layout.setOnClickListener(this);
  15. 		return view;
  16. 	}
  18. 	@Override
  19. 	public void refreshView(UserInfo data) {
  20. 		user_name.setText(data.getName());
  21. 		user_email.setText(data.getEmail());
  22. 		String url = data.getUrl();//image/user.png
  23. 		bitmapUtils.display(image_photo, HttpHelper.URL+"image?name="+url);
  24. 		
  25. 	}
  27. 	@Override
  28. 	public void onClick(View v) {
  29. 		switch (v.getId()) {
  30. 		case R.id.photo_layout:
  31. 			//  连接服务器 ...登录
  32. 			ThreadManager.getInstance().createLongPool().execute(new Runnable() {
  33. 				
  34. 				@Override
  35. 				public void run() {
  36. 					UserProtocol protocol=new UserProtocol();
  37. 					final UserInfo load = protocol.load(0);
  38. 					UiUtils.runOnUiThread(new Runnable() {
  39. 						@Override
  40. 						public void run() {
  41. 							setData(load); // 当调用该方法的时候  就会调用refreshView
  42. 						}
  43. 					});
  44. 				}
  45. 			});
  46. 			break;
  47. 		}
  48. 	}
  50. }
详情界面
 解析json：jsonobj解析可以都写在一个bean对象里,它并补关心括号前的字，只需要把属性定义出来

DetailActivity  
从上到下，每个都是holder，先实现不带箭头的

布局（下面是个帧布局，上面是Scrollview，每像界面是帧布局，直接把每个holder添加进去就行）：
  1. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
