移入画面は、私はカスタムリストにWebサイトから情報を掻き取り、画面を移入したい

Question

リストに情報をこすり落とし、私はこのウェブサイトからjsoup使用してデータを解析されてきました

public class ScoresActivity extends ListActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.scoresactivity); 

    setListAdapter(new MyAdapter(this, android.R.layout.simple_list_item_1, R.id.textViewhometeam, 
       getResources().getStringArray(R.array.pls))); 

    final ListView lv = getListView(); 
    lv.setTextFilterEnabled(true); 

    lv.setOnItemClickListener(new OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) { 
        // When clicked, show a toast with the TextView text 
        //int pos = lv.getSelectedItemPosition(); 
        //if(pos == 0){ 
         //Intent intent = new Intent(Legends.this, l1.class); 
         //startActivity(intent); 
        //} 

     } 
    }); 

} 

public class MyAdapter extends ArrayAdapter<String>{ 

    public MyAdapter(Context context, int resource, int textViewResourceId, 
      String[] strings) { 
     super(context, textViewResourceId, strings); 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     View row = inflater.inflate(R.layout.list_item3, parent, false); 

     //String[] items = getResources().getStringArray(R.array.legends); 

     TextView tv1 = (TextView) row.findViewById(R.id.textViewhometeam); 
     TextView tv2 = (TextView) row.findViewById(R.id.textViewfinalscore); 
     TextView tv3 = (TextView) row.findViewById(R.id.textViewawayteam); 

     Document doc; 
     try { 
      doc = (Document) Jsoup.connect("http://www.soccerway.com/teams/saudi-arabia/al-nasr-riyadh/matches/").get(); 
      Elements team_a = ((Element) doc).select("td.team-a"); 
      for (Element e : team_a) { 
       CharSequence ta = e.text(); 
       tv1.setText(ta); 
       //System.out.println("team a is: " + ta); 
      } 

      Elements team_b = ((Element) doc).select("td.team-b"); 
      for (Element e : team_b) { 
       CharSequence tb = e.text(); 
       tv3.setText(tb); 
       //System.out.println("team b is: " + tb); 
      } 

      Elements result = ((Element) doc).select("td.score"); 
      for (Element e : result) { 
       CharSequence re = e.text(); 
       tv2.setText(re); 
       //System.out.println("score is: " + re); 
      } 
     } catch (IOException e1) { 
      // TODO Auto-generated catch block 
      e1.printStackTrace(); 
     } 




     return row; 

    } 


} 

}

scoresactivity.xmlは、単にリストビュー0123ですが、私はそれがここで実行時例外が発生したコードとエラートレースしている私のアプリを起動カントlist_item3.xmlは私のカスタムリストです。ホームチーム、アウェーチーム、スコアの3つのテキストビューを含んでいます。ここ

は誤りである：ここでは

は私のメインクラスがTabActivityを拡張し、TabHost

public class Main extends TabActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 

    setContentView(R.layout.main); 

    getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custome_title); 

    Resources res = getResources(); 
    TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost); 
    TabHost.TabSpec spec; 
    Intent intent; // Reusable Intent for each tab 
    tabHost.getTabWidget(); 


    // Create an Intent to launch an Activity for the tab (to be reused) 
    intent = new Intent().setClass(this, ClubActivity.class); 

    // Initialize a TabSpec for each tab and add it to the TabHost 
    spec = tabHost.newTabSpec("club").setIndicator("", 
         res.getDrawable(R.drawable.ic_tab_alnassr)) 
        .setContent(intent); 
    tabHost.addTab(spec); 

    // Do the same for the other tabs 
    intent = new Intent().setClass(this, ScoresActivity.class); 
    spec = tabHost.newTabSpec("scores").setIndicator("", 
         res.getDrawable(R.drawable.ic_tab_alnassr1)) 
        .setContent(intent); 
    tabHost.addTab(spec); 

    intent = new Intent().setClass(this, TableActivity.class); 
    spec = tabHost.newTabSpec("table").setIndicator("", 
         res.getDrawable(R.drawable.ic_tab_alnassr2)) 
        .setContent(intent); 
    tabHost.addTab(spec); 

// Create an Intent to launch an Activity for the tab (to be reused) 
    intent = new Intent().setClass(this, MessageList.class); 

    // Initialize a TabSpec for each tab and add it to the TabHost 
    spec = tabHost.newTabSpec("News").setIndicator("", 
         res.getDrawable(android.R.drawable.star_on)) 
        .setContent(intent); 
    tabHost.addTab(spec); 

    intent = new Intent().setClass(this, YoutubeActivity.class); 
    spec = tabHost.newTabSpec("youtube").setIndicator("", 
         res.getDrawable(R.drawable.ic_tab_alnassr3)) 
        .setContent(intent); 
    tabHost.addTab(spec); 

    tabHost.setCurrentTab(0); 
} 

} おかげでみんなを使用しています。

Answer 1

あなたの活動com.nassr.alnassrfc.Mainがタブホストのためにandroid.R.id.tabhostを期待していたので、読み込めないことはログからかなり明らかです。あなたのレイアウトとcom.nassr.alnassrfc.Mainの活動を確認します。そのアクティビティはtabhostを拡張しますか？レイアウトにタブホストがないのはなぜですか？

投稿したコードがバグに関連しているとは思わない。
