我正在制作一个 Twitter 客户端作为学习 Android 的练习，并且登录和时间线活动工作正常，但是当我单击操作栏图标时，它会将我带到一个ComposeTweetActivity.java，然后在我输入文本（我的推文）并按Tweet 按钮来撰写推文，它不做任何事情（它应该实际将其上传到我的 Twitter 帐户，然后将我返回到我的TimelineActivity.java）。在控制台中，它给了我错误：

04-14 18:10:34.797: E/SQLiteLog(998): (1) no such table: Users

04-14 18:10:34.805: E/SQLiteDatabase(998): android.database.sqlite.SQLiteException: no such table: Users (code 1): , while compiling: INSERT INTO Users(user_name,friends_count,profile_background_image_url,Tweet,user_id,screen_name,Id,tweet_count,profile_image_url,followers_count) VALUES (?,?,?,?,?,?,?,?,?,?)

加上许多其他错误。我的猜测是它必须与 Active Android 相关，这是我用来保存的数据库。我在这个项目中有很多很多文件，但我会发布，ComposeTweetActivity.java因为它有撰写推文按钮（这会导致所有错误），User.java并且Tweet.java是 Active Android 的模型（我认为？）以及所有表数据，以及带有所有错误的控制台。如果您需要我发布更多文件，很乐意提供帮助。非常感谢您的帮助，提前。

天哪，答案最终是模拟器中的一个错误。事实证明，使用模型从 Twitter API 中绘制的 Twitter 客户端（我使用的是 Active Android，但您也可以只使用原始 SQLite 数据库表）......只会在未绘制表的情况下填充数据已经。因此，在我的情况下，进行大量更改并重新运行应用程序意味着您要求重新填充并创建一个数据表，但它已经创建了。

所以解决方案是在你的模拟器中卸载应用程序（或者只是使用一个新的模拟器）并再次重新运行程序！这将从头开始重新创建它，这是您的代码所要求的。它就像一个魅力。如此简单，却又如此棘手。>_<

你可以用我的方法测试添加到 AndroidManifest.xml：

<meta-data android:name="AA_MODELS" android:value="com.codepath.apps.mytwitterapp.models.User, com.codepath.apps.mytwitterapp.models.Tweet" />
