这是你的问题
for(int k = 0; k < hostimage_arr.length(); k++)
{
//Add this line
JsonObject innerObj=hostimage_arr.getJsonObject(k);
String image = js.getString("images"); // change it to innerObj.getString("images");

答案 1 :(得分：0)
您的第二个jsonarray（getuserlistdata）位于数据对象下。但你试图从userinfo jsonarray获取。删除usserarr的循环它将解决您的问题。
Userarr=jsonObj.getJSONObject("data").getJSONArray("userinfo");
// looping through All Contacts
删除循环
for (int i = 0; i < Userarr.length(); i++) {
JSONObject c = Userarr.getJSONObject(i);
String Fname=c.getString("firstname");
Fname_arr.add(Fname);
Log.v("Fname",Fname);
//change this
JSONArray _jArrImg = jsonObj.getJSONObject("data").getJSONArray("getuserlistdata");
for (int j = 0; j < _jArrImg.length(); j++) {
JSONObject js = _jArrImg.getJSONObject(j);
JSONArray hostimage_arr = c.getJSONArray("hostImage");
for(int k = 0; k < hostimage_arr.length(); k++)
{
// you are try get image from js object create a new object
JSONObject hostimage = hostimage_arr.getJSONObject(k);
String image = hostimage.getString("images");
if (_jArrImg.length() ==0) {
det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/user_12707aaf22_original.jpg");
}
if (j==0) {
det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/"+image);
}
}
答案 2 :(得分：0)
使用您的代码更改此代码：
问题：您尝试从"images"对象获取js。
JSONArray hostimage_arr = c.getJSONArray("hostImage");
for (int k = 0; k < hostimage_arr.length(); k++) {
JSONObject jImage = _jArrImg.getJSONObject(j); // Add this line
String image = jImage.getString("images"); // Update this line
if (_jArrImg.length() == 0) {
det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/user_12707aaf22_original.jpg");
}
if (j == 0) {
det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/"
+ image);
}
}
答案 3 :(得分：0)
您需要制作不同的jsonobject，以便从您的回复中获取不同的数组。
JSONObject jsonObjgetuserlistdata = response.getjObj();
JSONObject jobj , iobjimage;
JSONArray jsonQueryArray = new JSONArray(jsonObjQuery .getString("getuserlistdata"));
JSONArray jsonTeacherArray = new JSONArray(jsonObjTeacher .getString("teacher"));
for (int i = 0; i < jsonObjgetuserlistdata .length(); i++) {
jobj = jsonObjgetuserlistdata .getJSONObject(i);
JSONArray jsonImageArray = new JSONArray(jobj .getString("hostImage"));
for (int j = 0; j < jsonImageArray .length(); j++) {
iobjimage= jsonQuestionArray.getJSONObject(j);
image = iobjimage.getString("images"
}
}
答案 4 :(得分：0)
使用Gson库。 请检查以下链接 https://github.com/google/gson
为此你只需要为你的回复创建java pojo。
并调用以下方法：
new Gson（）。fromJson（userString，YourResponsePojo.class） 这将返回您的响应对象
