截屏：

JSON HTTP 响应：

     */
    public static String getName() {
        return name;
    }

    /**
     * @return the videos
     */
    public static String getContent() {
        return content;
    }

    /**
     * @return the videos
     */
    public static String getPublished() {
        return published;
    }
}

You have

CommentsLibrary lib = new CommentsLibrary(jsonString, jsonString, jsonString);

传递给 CommentsLibrary 构造函数的所有参数是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;
    }

所以它与获取相应字段的方法时显示的内容相同

Edit:

将列表声明为实例变量

 ArrayList<CommentsLibrary> list = new ArrayList<CommentsLibrary>();

Then

     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));
     }

Then in onPostExecute

使用带有自定义适配器的 ListView 并使用以下内容填充列表视图ArrayList list.

使用文本视图，您只能看到一组值。
