标题听起来有点混乱，但我正在从网站解析信息并将其存储在arraylist<string>. 一旦我ArrayList<String> mPictures = new GetTeachers().execute("div.post_thumb_clean img", "src").get();存储了asynctask我正在使用的结果，我就会使用ArrayList<Teacher> = mTeachers并mTeachers.add(new Teacher(Splash.mNames, Splash.mEmails, Splash.mPictures));在我的TeacherAdapter. 问题是，每当我运行所有这些时，只会listitem出现一个，而不是应该出现的 11 个左右。我认为问题出现在我用作listitem. 好吧，我不确定如何表达所有这些，因为我是自己学习的，我不确定我的术语是否正确，但我将在下面发布每个必要文件的摘录。谢谢！另外，很抱歉代码的垃圾，请随时编辑它。
AsyncTask (GetTeachers.class)

mInfo.add(element.absUrl(param[1]));
