新浪微博客户端开发之adapter

2013年11月23日 新浪微博客户端系列博客记录

之前获取首页微博列表还没有介绍adapter，关于adapter可以分出来一块来讲，用过ListView的童鞋们肯定对adapter不会陌生，下面是Android提供的一些Adapter，适用与一些简单的数据填充。

• BaseAdapter是一个抽象类，继承它需要实现较多的方法，所以也就具有较高的灵活性；
• ArrayAdapter支持泛型操作，最为简单，只能展示一行字。
• SimpleAdapter有最好的扩充性，可以自定义出各种效果。
• SimpleCursorAdapter可以适用于简单的纯文字型ListView，它需要Cursor的字段和UI的id对应起来。如需要实现更复杂的UI也可以重写其他方法。可以认为是SimpleAdapter对数据库的简单结合，可以方便地把数据库的内容以列表的形式展示出来。

到了新浪微博这里就需要自定义Adapter了，使用Android提供的adapter已经不能满足需求了，目前小巫所开发的有以下自定义adapter：

AppsListAdaper：用于显示联想搜索得到的app列表。
CommentListAdapter：用于显示评论列表。
FaceListAdapter：用于显示表情列表。
MSGAdapter：用于显示消息页面列表。
UsersListAdaper：用于显示联想搜索得到的User列表。
WeiboListAdapter：用于显示微博列表（首页、收藏、@我的）。
WeiboListNoMoreAdapter：在WeboListAdapter基础上去掉“更多”的adapter。

首页界面效果：

今天我只介绍WeiboListAdapter

/xiaowu_twitter/src/com/wwj/sina/weibo/adapters/WeiboListAdapter.java

WeiboListAdapter是稍显复杂的，因为它要显示的数据比较多，涉及到微博图片的显示，转发内容的显示，先来看看代码先吧。

// 通知更新列表数据}}

关于adapter我们需要关注getView这个方法，因为我们要显示的内容都在这里完成，由于每一条的微博数据比较多，所以童鞋们要注意每一项内容显示到哪个控件上。显示的数据是通过构造方法传进来的，每一条微博数据就是一个Status对象，所以我们需要定义相应的实体类，这个类我们怎么知道怎么定义，这就要知道请求API所返回的内容，

比如：https://api.weibo.com/2/statuses/home_timeline.json。我们请求这个API的时候，返回的字段就是我们需要定义的,如果不太清楚，既要好好看看一下开放平台给我们说明。

可以到这里查看：http://open.weibo.com/wiki/2/statuses/home_timeline。

那里很清楚说明了，请求方式，请求参数还有返回的json数据结构。

我们在授权第三方应用程序访问用户的数据成功后，就会异步获取用户首页微博数据，然后显示到界面上。

在认证成功后，回调onComplete方法，就会获取用户个人信息，显示到标题上。下面的代码我解释一下：

statuses的数据是由WeiboManager类当中getHomeTimelineAsync返回来的，这方法传入了一个监听器，StatusRequestListenerImpl这里类实现AsyncWeiboRunner类的RequestListener接口。

LinearLayout ll_home_layout = (LinearLayout) homeActivity.findViewById(R.id.ll_home_layout);List<Status> statuses = WeiboManager.getHomeTimelineAsync(homeActivity,new StatusRequestListenerImpl(homeActivity, ll_home_layout,HOME));weiboListAdapter = new WeiboListAdapter(activity, statuses, Const.HOME);homeActivity.homeTimelineAdapter = weiboListAdapter;homeActivity.imageWorkQueueMonitor = Tools.getGlobalObject(homeActivity).getImageWorkQueueMonitor(homeActivity);homeActivity.taskWorkQueueMonitor = Tools.getGlobalObject(homeActivity).getTaskWorkQueueMonitor(activity);homeActivity.imageWorkQueueMonitor.addDoneAndProcess(Const.HOME,weiboListAdapter);

AsyncWeiboRunner这个就是实现异步请求数据的类，通过构造函数传入进来的listener,调用它的onComplete方法就可以把请求的数据得到。

所以真正显示数据的地方在StatusRequestListenerImpl里，通过回调onComplete方法得到的respone,respone就是请求api返回的json数据，我们通过JSONAndObject的convert方法，将json字符串转换为以status作为元素的List。之后就是通过handler发送消息，在界面显示数据了，具体细节你们需要好好看看代码。

这篇博客的关键点应该不在adapter这里，如何异步更新UI才是最重要的，我这里使用的是handler来更新UI。线程的异步操作就主要通过AsyncWeiboRunner这个类实现，这部分内容就已经囊括了其他微博数据的获取实现流程，获取收藏列表和提到我的微博列表都是类似的实现，我就不多介绍了。
