Android 编程之第三方开发 MaoZhuaWeiBo微博开发演示样例-1

在大学期间我做过非常多类似这种APP。这个是我们小组之前做的，我后期增加非常多新元素。完好了这个应用，由于为了加强

专业技术嘛。也是常常熬夜写些小东西，嘿嘿。只是还算不错。起码技术长进了不少嘛，还是非常欣慰的，今天给大家说说腾讯

微博第三方拓展client开发。说白了就是调用第三方接口的开放平台进行二次开发，跟微信有些类似吧，好了，不扯了。立即

进入正题吧

开发前准备：

① 腾讯QQ号(相信大家都有) ②腾讯微博 App key （申请地址:http://dev.t.qq.com/） ③API地址：http://wiki.open.t.qq.com/index.php/API%E6%96%87%E6%A1%A3

可能有些人会问。为什么不用新浪微博开发呢？ 我就这么说吧，新浪的审核超慢。。

。等审核下来，预计咱们早就写完了

然后就開始着手我们的微博撰写了，把基本的架子搭好，我个人感觉先功能在UI比較好。由于UI后写的话，能够相对降低工作量，由于主要核心还是在功能，而UI是给用户不同的视觉体验吧

创建好Project之后，先给咱们的清单文件xml载入权限代码：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

接下来就是应用程序启动Activity，LoginActivity

由于我的IU写得太渣。。

。

布局文件就。

。。。有兴趣的话还是看源代码吧，讲完这个APP之后将会贴上来

结果图，个人信息界面，网络抓取。解析，没有网络时。保存了最后一次动态的数据在本地：






数据都是来自腾讯server的。不是本地的。首页界面：






这个GridView我还没有做不论什么拓展。只是我前面说到的的天气预报和文件管理器能够嵌入进来，能够解决掉一半，有兴趣的能够继续写下去，还有附近功能，我有时间会把它写了，贴出来，供大家学习

OK,前期的工作已经KO了，以下说说access_token凭证，他的有效时间是30天，假设出现key与凭证不匹配的情况下，能够卸载应用，或者将凭证刷新，就可以解决失效与不匹配的问题了。好了，第一篇就到这吧！
