将ArrayList放入参数JsonObject

Question

我必须通过Volley Framework提出要求。这是带有JSONObject的POST请求。

我必须传递一个字符串和一个JSONArray ..但是我怎么能呢？

我从这个开始：

 private String mUrl;
    private ArrayList<String> mUrlDove;

  HashMap<String, String> params = new HashMap<String, String>();
            params.put("url", mUrl);
            params.put("urlDove", mUrlDove); ---> Wrong because mUrlDove is not a String


            mUrl = app.getInstance().getmUrlRestWS() + getString(R.string.path);

            JsonObjectRequest mRequest = new JsonObjectRequest(
                    mUrl, new JSONObject(params),
                    createMyReqSuccessListener(),
                    createMyReqErrorListener()) {
                @Override
                public Map<String, String> getHeaders() throws AuthFailureError {
                    return app.getInstance().createBasicAuthHeader();
                }
            };

如果我尝试使用浏览器，则必须进行以下设置：

{
  "url": "www.secret.com",
  "urlDove" : [ "www.google.com","www.yahoo.com"]
}

您需要先制作一个JSON数组，然后将其存储

private String mUrl;
private ArrayList<String> mUrlDove;

HashMap<String, String> params = new HashMap<String, String>();
        params.put("url", mUrl);
        JSONArray jsArray = new JSONArray(mUrlDove);
        params.put("urlDove", jsArray.toString());

        mUrl = app.getInstance().getmUrlRestWS() + getString(R.string.path);

        JsonObjectRequest mRequest = new JsonObjectRequest(
                mUrl, new JSONObject(params),
                createMyReqSuccessListener(),
                createMyReqErrorListener()) {
            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                return app.getInstance().createBasicAuthHeader();
            }
        };
