我几天来一直在敲打这个。我做了大量的研究并尝试了一大堆不同的方法，但我似乎无法让它发挥作用。
我要做的是在for循环中设置动态布局，同时处理JSON响应中的多行。
返回五个数据库字段，包括我的Web服务器上图像的路径。
问题不是分配和显示数据和图像，问题是将它们全部显示在正确的位置。
我的代码恢复为可怕的基本表格布局和多行。
这就是它现在正在做的事情......（对于无法发布图像表示歉意，但显然我需要一些堆栈点才能这样做 - 每行代表一个表格行。）
|图片|
|数据|
|数据|
|数据数据|
这是代码（我知道不是我需要的）来设置它......

这是我真正需要的......图像位于所有四个数据行的左侧。

有人可以指出我正确的方向吗？
非常感谢我提供的任何帮助。
答案 0 :(得分：2)
您可以在单独的xml文件中定义要显示的单个项目（这将帮助您设计视图），然后将xml动态加载到TableLayout或ListView（我更喜欢后者）。
您是否考虑使用适配器（如BaseAdapter）来执行此操作？
