我知道了。大约一年后，我回答了这个问题，因为我看到这个帖子有几百位访客。希望我的回答将帮助其他功能访问者从onResponse方法获取数据。这是代码：
String insertUrl = "http://localhost/file.php";String lastInsertId;@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext()); StringRequest request = new StringRequest(Request.Method.POST, insertUrl, new Response.Listener<String>() { @Override public void onResponse(String response) { lastInsertId = response.toString(); System.out.println(lastInsertId); // returns the lastInsertId callback.onSuccess(lastInsertId); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { } }) { @Override protected Map<String, String> getParams() throws AuthFailureError { Map<String, String> parameters = new HashMap<String, String>(); // parameters return parameters; } }; requestQueue.add(request);}public interface VolleyCallback{ void onSuccess(ArrayList<Data> dataArrayList);}这是我们在Activity中需要的代码。
public void onResume(){ super.onResume(); getString(new VolleyCallback(){ @Override public void onSuccess(String result){ System.out.println(result); // returns the value of lastInsertId } });}
