JSON字符串未正确映射到textviews
我有3个文本视图，我试图用来自JSON Http响应的数据填充，但是他们当前正在使用来自响应的不正确数据填充。
由于某种原因，它没有解析字段并正确分配它们 - 它似乎只是用JSON响应中的数据开头填充每个文本视图。

1 个答案:
答案 0 :(得分：0)
你有
CommentsLibrary lib = new CommentsLibrary(jsonString, jsonString, jsonString);
传递给CommentsLibrary的构造函数的所有参数都是jsonString。这三个都有相同的jsonstring。
public CommentsLibrary(String name, String content, String published) {
this.name = name;
this.content = content;
this.published = published;
}
因此，获取相应字段的方法时显示的内容相同
编辑：
将列表声明为实例变量
ArrayList<CommentsLibrary> list = new ArrayList<CommentsLibrary>();
然后
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String name = jsonObject.optString("name","defaultValue");
String content = jsonObject.optString("content","defaultValue");
String published = jsonObject.optString("published","defaultValue");
list.add(new CommentsLibrary(name, content, published));
}
然后在onPostExecute
使用带有自定义适配器的ListView，并使用ArrayList list填充列表视图。
使用文本视图，您只能看到一组值。
