My JSON response is like this:
["item1","item2",...]
Now, I want to add each of the array items into my spinner
:
@Override
public void onResponse(Call<String> call, Response<String> response) {
if (response.body() != null) {
String[] arr=response.body().split(",");
arr[0]=arr[0].replace("[","");
arr[arr.length-1]=arr[arr.length-1].replace("]","");
Arrays.sort(arr);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(view.getContext(), android.R.layout.simple_spinner_item,arr);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
if (qrtr_reg != null) {
qrtr_reg.setAdapter(adapter);
}
}
}
All my spinner items are in double quotes(""), which I don't want. I want them in object format. How do I fix this?
EDIT: Tried the following code:
ArrayList<String> arr=new ArrayList<String>();
JSONArray array = null;
try {
array = new JSONArray(response.body());
for(int i=0;i<array.length();i ){
arr.add(String.valueOf(array.getJSONObject(i).getString(0)));
}
} catch (JSONException e) {
e.printStackTrace();
}
Collections.sort(arr);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(view.getContext(), android.R.layout.simple_spinner_item,arr);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
if (qrtr_reg != null) {
qrtr_reg.setAdapter(adapter);
}
Now, my spinner is completely empty!!
CodePudding user response:
Your second piece of code is almost correct. Here is the mistake:
arr.add(String.valueOf(array.getJSONObject(i).getString(0)))
Your array is not an array of JSON objects, it is an array of strings directly. Therefore, here is what that line should look like:
arr.add(array.getString(i))
(I'm guessing you copied your attempt from this answer, but the question there has an array of objects, and your array is much simpler.)
