我从循环Utils.log（＆＃34; studio_name：＆＃34; + studio_name）得到的结果是：
studio_name: Dodi fit
studio_name: inu fit
studio_name: Vstudio
studio_name: Infovendor
studio_name: Seleb Fitnes One
studio_name: Riri Studio
studio_name: NF Studio
这意味着我已经全部使用了循环。 但问题是结果没有填充到listview中（它显示为NF Studio的最后一个结果，另一个没有出现）。
我需要的是将其填充到country_info的4 texview中（我禁用imageview）：
String studio_name, address, website, seo_url
在listview中显示/填充的正确代码是什么？
答案 0 :(得分：0)
将值添加到List并将其传递到Adapter内ListView的{{1}}类
答案 1 :(得分：0)
