android.database.CursorIndexOutOfBoundsException

Question

我運行的軟件，但是當我使用ListView滾動，其顯示正常，但一段時間後，我收到此錯誤信息：

我試圖顯示光標到ListView。

我的適配器類：

private class DBAdapter extends SimpleCursorAdapter { 
     private LayoutInflater mInflater; 
     private Cursor c; 
     private Context context; 

我的構造

 public DBAdapter(Context context, int layout, Cursor c, String[] from, int[] to) { 
      super(context, layout, c, from, to); 
      this.c = c; 
      this.context = context; 
      mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     } 

getView方法

 @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      ViewHolder holder = null; 
      if (convertView == null) { 
       holder = new ViewHolder(); 
       convertView = mInflater.inflate(R.layout.match_item, null); 
       holder.tvHome = (TextView)convertView.findViewById(R.id.ll_home); 
       convertView.setTag(holder); 
      } else { 
       holder = (ViewHolder)convertView.getTag(); 
      } 
       holder.tvHome.setText(c.getString(3)+"("+c.getString(6)+")"); 
       c.moveToNext(); 
       return convertView; 
     } 
    } 

簡單看法持有人

public static class ViewHolder { 
     public TextView tvHome; 
    } 
} 

適配器初始化

Cursor cur = dh.getAll(); 
    startManagingCursor(cur); 

    String[] from = new String[] { "home" }; 
    int[] to = new int[] { R.id.ll_home}; 

    // Now create an array adapter and set it to display using our row 
    DBAdapter matches = new DBAdapter(this,R.layout.match_item, cur, from, to); 
    setListAdapter(matches); 

誰能幫我解決這個問題？我到處找，但我找不到任何解決方案

最好的問候， 尼科斯

Answer 1

你應該實現自己的光標適配器，不getView當覆蓋newView和bindView。我發現這個：Trying to override getView in a SimpleCursorAdapter gives NullPointerExceptio

Answer 2

holder.tvHome.setText(c.getString(3)+"("+c.getString(6)+")"); 
if(position<=c.getCount())   
    c.moveToNext(); 
return convertView;  

Answer 3

既然你只有您將索引設爲0的單個元素。 您可以試試這一個c.getString（0）。我認爲它會工作
