Textview가 문자열을 보지 못합니다.

Question

저는 NewsApp을 만들고 ArrayAdapter를 사용하여 rss 링크에서 TextView로 제목과 날짜를 표시합니다. 그러나 그것을 실행할 때, TextView (s)는 인터넷에서 가져온 문자열 목록을 표시하지 않지만 문자열 목록은 생성자의 주소처럼 보입니다. 이처럼 :

com.example.sonyhater.test.Article@53699f88

com.example.sonyhater.test.Article@53622a78

등등 ...

도와주세요. (sonyhater 내 사용자 이름이고 제는 생성자의 이름)이 내 MainActivity

입니다 :

package com.example.sonyhater.test; 

import android.os.AsyncTask; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.util.Log; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 
import android.widget.Toast; 

import org.w3c.dom.Document; 
import org.w3c.dom.Element; 
import org.w3c.dom.Node; 
import org.w3c.dom.NodeList; 

import java.io.BufferedReader; 
import java.io.InputStreamReader; 
import java.net.URL; 
import java.net.URLConnection; 
import java.util.ArrayList; 
import java.util.List; 

public class MainActivity extends AppCompatActivity { 

ListView listView; 
ArrayAdapter mAdapter; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    listView = (ListView) findViewById(R.id.list); 

    runOnUiThread(new Runnable() { 
     @Override 
     public void run() { 
      new Readdata().execute("https://vnexpress.net/rss/the-gioi.rss"); 
     } 
    }); 
} 
class Readdata extends AsyncTask<String, Integer, String>{ 

    @Override 
    protected String doInBackground(String... params) { 
     return readFromURL(params[0]); 
    } 

    @Override 
    protected void onPostExecute(String s) { 
     List<Article> articles = new ArrayList<Article>(); 

     XMLDOMParser parser = new XMLDOMParser(); 
     Document document = parser.getDocument(s); 
     NodeList nodeList = document.getElementsByTagName("item"); 
     String title = ""; 
     String date =""; 
     for (int i = 0; i < nodeList.getLength(); i++){ 
      Element element = (Element) nodeList.item(i); 
      title = parser.getValue(element,"title"); 
      Toast.makeText(MainActivity.this, title, Toast.LENGTH_LONG).show(); 
      date = parser.getValue(element,"pubDate"); 

      articles.add(new Article(title, date)); 
     } 
     mAdapter = new ArrayAdapter(MainActivity.this, android.R.layout.simple_list_item_1, articles); 
     listView.setAdapter(mAdapter); 
     super.onPostExecute(s); 
    } 
} 

private String readFromURL(String theUrl){ 
    StringBuilder content = new StringBuilder(); 
    try { 
     // create a url object 
     URL url = new URL(theUrl); 

     // create a urlconnection object 
     URLConnection urlConnection = url.openConnection(); 

     // wrap the urlconnection in a bufferedreader 
     BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream())); 

     String line; 

     // read from the urlconnection via the bufferedreader 
     while ((line = bufferedReader.readLine()) != null){ 
      content.append(line + "\n"); 
     } 
     bufferedReader.close(); 
    } 
    catch(Exception e) { 
     e.printStackTrace(); 
    } 
    return content.toString(); 
} 

}

getValue (요소, "title")에서 Toast를 사용했으며 앱을 실행할 때 올바른 제목을 표시합니다. 어쩌면 어댑터 또는 XML (들)에 문제가 있습니까?

public class ArticleAdapter extends ArrayAdapter<Article> { 
private static final String LOG_TAG = ArticleAdapter.class.getSimpleName(); 
public ArticleAdapter(@NonNull Context context, int source, @NonNull List<Article> objects) { 
    super(context, source , objects); 
} 

@NonNull 
@Override 
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) { 
    View view = convertView; 
    if (view == null){ 
     view = LayoutInflater.from(getContext()).inflate(R.layout.list_item, null); 
    } 
    Article current = getItem(position); 

    TextView titleTV = (TextView) view.findViewById(R.id.the_title); 
    titleTV.setText(current.getTitle()); 

    TextView dateTV = (TextView) view.findViewById(R.id.date); 
    dateTV.setText(current.getDate()); 

    return view; 
} 
} 

생성자 :

public class Article { 
public String title; 
public String date; 

public Article(String title, String date) { 
    this.title = title; 
    this.date = date; 
} 

public String getTitle(){ 
    return title; 
} 
public String getDate(){ 
    return date; 
} 
} 

main_activity.xml :

<?xml version="1.0" encoding="utf-8"?> 
<ListView xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context="com.example.sonyhater.test.MainActivity" 
android:id="@+id/list"> 

</ListView> 

및 list_item.xml :

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:padding="16dp"> 

<TextView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="tieu de" 
    android:id="@+id/the_title" 
    android:textColor="@android:color/black" 
    /> 

<TextView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="ngay thang" 
    android:id="@+id/date" 
    android:textColor="@android:color/black"/> 

</LinearLayout>

List<Article> mArticle; 

이

this.mArticle=objects; 

사용이

titleTV.setText(mArticle.get(position).getTitle()); 

dateTV.setText(mArticle.get(position).getDate());
