私がやってきたことはcustomadapterについてです。リストビューから選択したアイテムを取得したいのですが、アダプターはカスタムです。私のリストビューには、画像、タイトル、キャプションがあります。選択したアイテムを取得したいのですが、私の場合はタイトルだけです。それ、どうやったら出来るの？

これが私がこれまでに試したことです：

    @Override
public void onItemClick(AdapterView<?> parent, View v, int pos, long id) {
    String strHouseName = "house_name";
    String strHousePrice = "house_price";
    //String selectedFromList =(String) (lv.getItemAtPosition(pos));
    Intent i;

    switch(pos){
    case 0:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "5 Dina Retreat, Carrum Downs");
        i.putExtra(strHousePrice, "$300,000.00");
        startActivity(i);
        break;
    case 1:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 941 Cob Terrace, Clyde North");
        i.putExtra(strHousePrice, "$800,000.00");
        startActivity(i);
        break;
    case 2:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 932 Ventasso Street, Clyde");
        i.putExtra(strHousePrice, "$1,000,000.00");
        startActivity(i);
        break;
    case 3:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 515 Summerhill Blvd, Drouin");
        i.putExtra(strHousePrice, "$300,000.00");
        startActivity(i);
        break;
    case 4:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 17 Todman Street, Drouin (Option 2)"); 
        i.putExtra(strHousePrice, "$550,000.00");
        startActivity(i);
        break;
    case 5:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 32 Aqueduct Road, Langwarrin");
        i.putExtra(strHousePrice, "$600,000.00");
        startActivity(i);
        break;
    case 6:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Units 2-7, 269 North Road, Langwarin");
        i.putExtra(strHousePrice, "$450,000.00");
        startActivity(i);
        break;
    case 7:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "U 39, 40-60 Potts Road, Langwarrin");
        i.putExtra(strHousePrice, "$1,300,000.00");
        startActivity(i);
        break;
    case 8:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 1 McClenaghan Place, Pakenham");
        i.putExtra(strHousePrice, "$2,000,000.00");
        startActivity(i);
        break;
    case 9:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 2 McClenaghan Place, Pakenham");
        i.putExtra(strHousePrice, "$300,000.00");
        startActivity(i);
        break;
    case 10:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 3 McClenaghan Place, Pakenham");
        i.putExtra(strHousePrice, "$900,000.00");
        startActivity(i);
        break;
    case 11:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 4 McClenaghan Place, Pakenham");
        i.putExtra(strHousePrice, "$600,000.00");
        startActivity(i);
        break;
    case 12:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 5 McClenaghan Place, Pakenham");
        i.putExtra(strHousePrice, "$1,200,000.00");
        startActivity(i);
        break;
    case 13:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 7 McClenaghan Place, Pakenham");
        i.putExtra(strHousePrice, "$700,000.00");
        startActivity(i);
        break;
    case 14:

        i.putExtra(strHousePrice, "$500,000.00");
        startActivity(i);
        break;
    case 15:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 12 McClenaghan Place, Pakenham");
        i.putExtra(strHousePrice, "$3,000,000.00");
        startActivity(i);
        break;
    case 16:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 532 Summerhill Blvd, Drouin");
        i.putExtra(strHousePrice, "$300,000.00");
        startActivity(i);
        break;
    case 17:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 17 Ajax Street, Drouin");
        i.putExtra(strHousePrice, "$300,000.00");
        startActivity(i);
        break;
    case 18:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 133 Mountainview Blvd, Cranbourne North");
        i.putExtra(strHousePrice, "$300,000.00");
        startActivity(i);
        break;
    case 19:
        i = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 531 Summerhill Blvd, Drouin");
        i.putExtra(strHousePrice, "$300,000.00");
        startActivity(i);
        break;
    default: Log.d(strHouseName, "No such house name available");
    } 

}


    class MyCustomAdapter extends BaseAdapter
{
    String[] data_text1;
    String[] data_text2;
    int[] data_image;

MyCustomAdapter() {
    data_text1 = null;
    data_text2 = null;
    data_image = null;
}

MyCustomAdapter(int[] image, String[] house, String[] price) {
    data_text1 = house;
    data_text2 = price;
    data_image = image;
}

public int getCount() {
    return data_text1.length;
}

public String getItem(int position) {
    return null;
}

public long getItemId(int position) {
    return position;
}

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

    LayoutInflater inflater = getLayoutInflater();
    View row;

    row = inflater.inflate(R.layout.listrow, null);

    TextView textview1 = (TextView) row.findViewById(R.id.text1);
    TextView textview2 = (TextView) row.findViewById(R.id.text2);
    ImageView imageview = (ImageView) row.findViewById(R.id.image);

    imageview.setScaleType(ImageView.ScaleType.FIT_XY);
    textview1.setText(data_text1[position]);
    textview2.setText("$" + (new DecimalFormat("#,###.00")).format(Double.parseDouble(data_text2[position])) );
    imageview.setImageResource(data_image[position]);

    return (row);

    }
}

とりあえず、その位置から取得するだけですが、問題は、リストがソートされている場合はどうなるかということです。正しい選択項目を取得するにはどうすればよいですか? 何か案は？よろしくお願いします。ありがとう。

例として確かに

//DatasetClass

public class HouseData{

    //private String HouseName= "";
    private String HousePrice = "";

    /*public String getHouseName() {
        return HouseName;
    }
    public void setHouseName(String HouseName) {
        this.HouseName= HouseName;
    }*/
    public String getHousePrice () {
        return HousePrice ;
    }
    public void setHousePrice (String HousePrice ) {
        this.HousePrice = HousePrice ;
    }

//viewholder クラスは次のとおりです:-

 public class ViewHolder
        {
            public TextView tv_HousePrice,tv_HouseName

        }

// そしてここに getview メソッドがあります。

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

            final ViewHolder holder;
            //holder=new ViewHolder();

            View listrow = convertView;

            activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

            if (listrow == null) {

                LayoutInflater vi = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                listrow = vi.inflate(R.layout.your_listview_item_layout, null);

                holder=new ViewHolder();
                holder.tv_HouseName=(TextView)listrow.findViewById(R.id.tv_name);


                holder.tv_HousePrice=(EditText)listrow.findViewById(R.id.tv_price);
                listrow.setTag(holder);

            }
            else
                holder=(ViewHolder)listrow.getTag();
            listrow.setBackgroundColor(((position % 2)!=0) ? Color.rgb(229,229,229) : Color.WHITE);

            try {
                houseData= getItem(position);



                if (houseData!= null) { 

                    holder.tv_HouseName.setText(""+houseData.getHouseName());
                    holder.tv_HousePrice.setText(""+houseData.getHousePrice());

                }
            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }

            listrow.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
//here you can pass complete data object to next activity
}
            });


            return listrow;
        }

ビューを取得してみてください。IDでテキストビューに解析します。テキストを取得して続行

これを試して..

public void onItemClick(AdapterView<?> parent, View v, int pos, long id) {
    // Type cast to what the layout you used in the xml i.e, for the list item
    // For example i took the RelativeLayout
    if(v instanceOf RelativeLayout){
        RelativeLayout layout = (RelativeLayout) v;
        TextView title = (TextView) layout.findViewById(R.id.conFormat_Name);
        System.out.println(title.getText());
    } 

}
