Android 编程之第三方开发 MaoZhuaWeiBo微博开发示例-1
浏览数：121 /
时间：2015年06月11日
在大学期间我做过很多类似这样的APP，这个是我们小组之前做的，我后期加入很多新元素，完善了这个应用，因为为了加强
专业技术嘛，也是经常熬夜写些小东西，嘿嘿，不过还算不错，起码技术长进了不少嘛，还是很欣慰的，今天给大家说说腾讯
微博第三方拓展客户端开发，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，马上
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，估计咱们早就写完了
然后就开始着手我们的微博撰写了，把主要的架子搭好，我个人感觉先功能在UI比较好，因为UI后写的话，可以相对减少工作量，因为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加载权限代码：
<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

因为我的IU写得太渣。。。布局文件就。。。，有兴趣的话还是看源码吧，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：
数据都是来自腾讯服务器的，不是本地的，首页界面：
这个GridView我还没有做任何拓展，不过我前面说到的的天气预报和文件管理器可以嵌入进来，可以解决掉一半，有兴趣的可以继续写下去，还有附近功能，我有时间会把它写了，贴出来，供大家学习
凭证抓取失败的结果，跳转至授权界面，授权成功，信息保存至首选项：
