Android Can'；t使用截图显示两个自定义ListView

我是android的初学者，我正在尝试使用Volley创建一个自定义列表，其中包含每个用户的图像列表和文本描述。有两个活动作为列表视图，使用截取下载json数据，使用McClickListener启动其他活动。第一个活动已完成运行，当我单击另一个活动时，Logcat没有显示任何内容，但第二个Listview活动为空，只有标题。。。 这是Logcat我不知道它是否有用

我所有的日志记录

05-22 16:09:32.549: V/Monotype(14980): SetAppTypeFace- try to flip, app = com.wangjian.klmeet_sightseeing

05-22 16:09:33.378: D/Volley(14980): [1] 2.onErrorResponse: MainActivity

我的代码如下所示：

第一个活动SightseeingActivity.java

public class SightseeingActivity extends Activity {
//Log tag
private static final String TAG = SightseeingActivity.class.getSimpleName();

//Sightseeing json url
private static final String url = "http://wangjian.site90.net/json/api_klmeet_sightseeing.json";
private ProgressDialog pDialog;

private ListView listView;
private CustomListAdapter adapter;


@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.sightseeing_activity);

    listView = (ListView) findViewById(R.id.sight_list);
    adapter = new CustomListAdapter(this, sightList);
    listView.setAdapter(adapter);

    pDialog = new ProgressDialog(this);
    // Showing progress dialog before making http request
    pDialog.setMessage("Loading...");
    pDialog.show();

    //changing action bar color
    getActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#1b1b1b")));

    //Creating volley request obj
    JsonArrayRequest sightReq = new JsonArrayRequest(url,new Response.Listener<JSONArray>() {
        @Override
        public void onResponse(JSONArray response){
            Log.d(TAG, response.toString());
            pDialog.dismiss();

            for (int i = 0; i < response.length(); i++){
                try{
                    JSONObject obj = response.getJSONObject(i);
                    Sight sight = new Sight();
                    sight.setTitle(obj.getString("title"));
                    sight.setThumbnailUrl(obj.getString("image"));
                    sight.setReadmore(obj.getString("readmore"));
                    sight.setPreintroduce(obj.getString("preintroduce"));
                    sight.setTag(obj.getString("tag"));

                    sightList.add(sight);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }

            //notifying list adapter about data changes
            //so that it renders the list view with updated data
            adapter.notifyDataSetChanged();
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error){
            VolleyLog.d(TAG, "Error: " + error.getMessage());
        }
    });
    // Adding request to request queue
            AppController.getInstance().addToRequestQueue(sightReq);
            listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                        int position, long id) {
                    Class<? extends Activity> activityToSrart = null;
                    switch (position){
                    case 0:
                        activityToSrart = MainActivity.class;
                        break;
                    case 1:
                        activityToSrart = MerdekaSquare.class;
                        break;
                    }

                    Intent i = new Intent(getApplicationContext(), activityToSrart);
                    startActivity(i);
                }

            });
    }

如果需要，我上传XML文件

feed_item.xml

首先，

私有字符串URL\u提要=”http://wangjian.site90.net/json/api_klmeet_sightseeing_face.json";main活动中的code>不存在，当我在
AdvanceRestClient中尝试它时，我得到了以下信息：


所以我试着更深入地研究WS的目录结构，发现上面并没有提到过这样的URL


此外，我在尝试访问您的目录时遇到了安全问题：


我不确定你在认真寻找什么，但你可以在
MainActivity
中尝试使用有效的
URL
，它应该可以正常工作

安全问题从文字上把我吓跑了（
是的，兄弟，我已经解决了问题，我的json有一些问题，所以我从我的网站上删除了这个json。这就是为什么你找不到URL，我很抱歉我应该结束这个问题，非常感谢你的帮助！很高兴知道你有这个问题：）
