这是我的Android代码。当我试图解析我的jsonArray时，它给了我一个错误，即字符串无法通过我的响应转换为Jsonarray是json数组：
public class Main2Activity extends AppCompatActivity {
EditText tv1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
tv1= (EditText) findViewById(R.id.textView);
DefaultOAuthConsumer defaultOAuthConsumer = new DefaultOAuthConsumer("my consumer key","my secret key");
//REQUEST URL
String url = "http://back.unaux.com/wp-json/wc/v2/products";
RequestQueue requestQueue;
requestQueue = Volley.newRequestQueue(this);
try {
url = defaultOAuthConsumer.sign(url);
Toast.makeText(this, url, Toast.LENGTH_SHORT).show();
} catch (OAuthMessageSignerException e) {
e.printStackTrace();
} catch (OAuthExpectationFailedException e) {
e.printStackTrace();
} catch (OAuthCommunicationException e) {
e.printStackTrace();
}
JsonArrayRequest req=new JsonArrayRequest(url, new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
Toast.makeText(Main2Activity.this, response.toString(), Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(Main2Activity.this,"Error"+error.getMessage(), Toast.LENGTH_SHORT).show();
}
});
requestQueue.add(req);
}
}
这是我对json的回应

你在array.Test中有数组：添加排球库
的OnCreate（）{
sendRequest将（）; }
private void sendRequest() { try { StringRequest stringRequest = new StringRequest(test_urls, new Response.Listener<String>() { @Override public void onResponse(String response) { Log.e("respnose", "" + response); parseJSON(response); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { progressDialog.dismiss(); Toast.makeText(Page_details_bkp.this, error.getMessage(), Toast.LENGTH_LONG).show(); } }); RequestQueue requestQueue = Volley.newRequestQueue(Page_details_bkp.this); requestQueue.add(stringRequest); } catch (Exception e) { progressDialog.dismiss(); Log.e("sendreq:", e.toString()); } } public void parseJSON(String json) { JSONObject jsonObject = null; try { jsonObject = new JSONObject(json); users = jsonObject.getJSONArray(JSON_ARRAY); try { userID = jsonObject.getString("api_status"); //ids = new String[jsonArray.length()]; if (userID.equals("success")) { ids = new String[users.length()]; names = new String[users.length()]; emails = new String[users.length()]; sub_images1 = new String[users.length()][3]; sub_ids = new String[users.length()][3]; // images = new String[users.length()]; //log.e("length :", users.length() + ""); for (int i = 0; i < users.length(); i++) { JSONObject jo = users.getJSONObject(i); ids[i] = jo.getString(KEY_ID); names[i] = jo.getString(KEY_NAME); emails[i] = jo.getString(KEY_EMAIL); try { JSONObject locArrObj = users.getJSONObject(i); // cotains one "out" array JSONArray conferenceLocArr = locArrObj.getJSONArray("posts"); if (conferenceLocArr.length() > 0) { // this array has two objects and each object has array JSONObject o = null; for (int ii = 0; ii < conferenceLocArr.length(); ii++) { o = conferenceLocArr.getJSONObject(ii); // it has one array try { // if (!o.getString("image").equals("")) { sub_images1[i][ii] = o.getString("image"); sub_ids[i][ii] = o.getString("id"); //log.e("Main response:", ids[i] + "," + ids[i] + "," + names[i] + "," + emails[i]); //} } catch (JSONException e) { e.printStackTrace(); //log.e("sub response:", e.toString()); } // sub_images1[i] = o.getString("image"); // do your work with Stage 1 and guests // and for second object for Stage 2 and guests. } Categories movie = new Categories(ids[i], names[i], emails[i], "2015", sub_images1[i][0],sub_ids [i] [0]，sub_images1 [i] [1]，sub_ids [i] [1]，sub_images1 [i] [2]， sub_ids [I] [2]）; movieList.add（电影）; } } catch（JSONException e）{ //log.e("response:"，e.toString（））; e.printStackTrace（）; } }
