这是我的代码，首先我想得到第一个问题和相关的值，如选项，答案。我搜索了它，但我没有得到任何与我的问题相关的解决方案。请帮帮我

我想将这些选项值设置为4个不同的文本视图，当用户点击任何文本视图（可点击）时，我想显示下一个问题及其相关选项，但我没有得到如何解析这个“选项” JSONArray

Answer 1

ArrayList<String> ls_options = new Arr...


for (int j = 0; j < q_options.length(); j++) {
      //  value = q_options.getJSONObject(j);
          ls_options.add(q_options.getJSONObject(j));

}

textview0.setText(ls_options.get(0));
textview1.setText(ls_options.get(1));
textview2.setText(ls_options.get(2));

你创建了value类型JSONObject，你在for-loop中分配它，所以它被覆盖
