将ArrayList放入参数JsonObject

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(); }        };
