Android：如何提取一行两列的数据

这是我的搜索活动代码

search.addTextChangedListener(new TextWatcher()
  {
  public void afterTextChanged(Editable s)
  {
                                                                  // Abstract Method of TextWatcher Interface.
  }
  public void beforeTextChanged(CharSequence s,
  int start, int count, int after)
  {
  // Abstract Method of TextWatcher Interface.
  }
  public void onTextChanged(CharSequence s,
  int start, int before, int count)
  {
  textlength = search.getText().length();
  array_sort.clear();
  for (int i = 0; i < listview_array.length; i++)
  {
  if (textlength <= listview_array[i].length())
  {
  if(search.getText().toString().equalsIgnoreCase(
  (String)
  listview_array[i].subSequence(0,
  textlength)))
  {
      array_sort.add(listview_array[i]);
      }
   }}

  listContent1.setAdapter(new ArrayAdapter<String>
  (Search_Food.this,
  android.R.layout.simple_list_item_1, array_sort));
  }

  });

我的数据库适配器

public LinkedList<String> search(String string) {
    // TODO Auto-generated method stub
    LinkedList<String> results = new LinkedList<String>();
    Cursor cursor = null;
    String search = string;
    try{
        cursor = this.sqLiteDatabase.query(true, MYDATABASE_TABLE , new String[] { KEY_ID , KEY_FOODNAME , KEY_CALORIES  }, KEY_FOODNAME  + " = ?" + "COLLATE NOCASE", 
                new String[] { search }, null, null, null, null);

        if(cursor!=null && cursor.getCount()>0 && cursor.moveToFirst()){

            int foodName = cursor.getColumnIndex(KEY_FOODNAME );
            int keyColories = cursor.getColumnIndex(KEY_CALORIES );

           // boolean moveToNext = cursor.moveToNext();
            //do{
                results.add(
                    new String(

                       cursor.getString(foodName) + "                              " +
                        cursor.getString(keyColories)
                    )
                );
            //}while(moveToNext);
        }
    }catch(Exception e){
        Log.e(APP_NAME, "An error occurred while searching for "+search+": "+e.toString(), e);
    }finally{
        if(cursor!=null && !cursor.isClosed()){
            cursor.close();
        }
    }

    return results;
}

公共链接列表搜索（字符串）{
//TODO自动生成的方法存根
LinkedList结果=新建LinkedList（）；
游标=空；
字符串搜索=字符串；
试一试{
cursor=this.sqLiteDatabase.query（true，MYDATABASE_表，新字符串[]{KEY_ID，KEY_FOODNAME，KEY_carries}，KEY_FOODNAME+“=？”+“COLLATE NOCASE”，
新字符串[]{search}，null，null，null，null）；
if（cursor！=null&&cursor.getCount（）>0&&cursor.moveToFirst（））{
int foodName=cursor.getColumnIndex（KEY_foodName）；
int keyColories=cursor.getColumnIndex（KEY_）；
//布尔moveToNext=cursor.moveToNext（）；
//做{
结果。添加(
新字符串(
cursor.getString（foodName）+“”+
cursor.getString（keyColories）
)
);
//}while（moveToNext）；
}
}捕获（例外e）{
Log.e（APP_NAME，“搜索“+search+”：“+e.toString（），e”时出错）；
}最后{
if（cursor！=null&！cursor.isClosed（））{
cursor.close（）；
}
}
返回结果；
}

现在，当我在搜索的listview上单击一个数据时，我想将getitemposition提取为2，这就是我的列。食物名称和卡路里。如何将这两个值分开

请回答。帮助谢谢你

你已经得到答案了吗？没有，先生@festustamakloe应该使用SimpleCursorAdapter而不是ArrayAdapter。@HoanNguyen那里我该如何使用SimpleCursorAdapter？“救命？”FestusTamakloe先生，我又给你发电子邮件了

public LinkedList<String> search(String string) {
    // TODO Auto-generated method stub
    LinkedList<String> results = new LinkedList<String>();
    Cursor cursor = null;
    String search = string;
    try{
        cursor = this.sqLiteDatabase.query(true, MYDATABASE_TABLE , new String[] { KEY_ID , KEY_FOODNAME , KEY_CALORIES  }, KEY_FOODNAME  + " = ?" + "COLLATE NOCASE", 
                new String[] { search }, null, null, null, null);

        if(cursor!=null && cursor.getCount()>0 && cursor.moveToFirst()){

            int foodName = cursor.getColumnIndex(KEY_FOODNAME );
            int keyColories = cursor.getColumnIndex(KEY_CALORIES );

           // boolean moveToNext = cursor.moveToNext();
            //do{
                results.add(
                    new String(

                       cursor.getString(foodName) + "                              " +
                        cursor.getString(keyColories)
                    )
                );
            //}while(moveToNext);
        }
    }catch(Exception e){
        Log.e(APP_NAME, "An error occurred while searching for "+search+": "+e.toString(), e);
    }finally{
        if(cursor!=null && !cursor.isClosed()){
            cursor.close();
        }
    }

    return results;
}
