Volley JsonObjectRequest

Question

我只是试图将json web-service解析为一个数组，问题只是list-view上显示的第一个项目。我应该怎么做才能生成完整的json数组出现在列表视图中？

private void makeJsonObjectRequest() {
    showpDialog();
    final JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.GET,
            urlJsonObj, null, new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            Log.d(TAG, response.toString());

            try {
                JSONArray snap = response.getJSONArray("arr_0");
                String[] list = new String[snap.length()];
                 for (int i = 0; i < snap.length(); i++) {
                     list[i] = snap.getJSONObject(i).getString("title");
                     list[i] = snap.getJSONObject(i).getString("description");
                     list[i] = snap.getJSONObject(i).getString("url");
                     list[i] = snap.getJSONObject(i).getString("sort");
                     list[i] = snap.getJSONObject(i).getString("attachment_id");
                     list[i] = snap.getJSONObject(i).getString("thumb");
                     list[i] = snap.getJSONObject(i).getString("image");
                     list[i] = snap.getJSONObject(i).getString("height");
                     list[i] = snap.getJSONObject(i).getString("width");
                }
                snapActivity.this.lv.setAdapter(new ArrayAdapter(snapActivity.this,android.R.layout.simple_list_item_1, list));
            } catch (JSONException e) {
                e.printStackTrace();
                Toast.makeText(getApplicationContext(),
                        "Error: " + e.getMessage(),
                        Toast.LENGTH_LONG).show();
            }
            hidepDialog();
        }

我已经弄明白了，你只需要使用自定义适配器将数据填充到listView
