Question

我一直在做的是关于customadapter.现在我想从列表视图中获取所选项目,但它的适配器是自定义的.在我的列表视图中,我有一个图像,标题和标题,我想获得所选项目,在我的情况下只是标题.我怎么做？

这是我到目前为止所尝试的:

    @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 = new Intent(this, ViewHouse.class);
        i.putExtra(strHouseName, "Lot 11 McClenaghan Place, Pakenham");
        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);

    }
}

同时,我只是通过它的位置,但问题是,如果列表被排序怎么办？如何获得正确的选定项目？有任何想法吗？我很乐意欣赏它.谢谢.

试试这个..

@Override
public void onItemClick(AdapterView<?> parent, View v, int pos, long id) {

    TextView textview1 = (TextView) v.findViewById(R.id.text1);
    TextView textview2 = (TextView) v.findViewById(R.id.text2);

    Log.v("textview1",textview1.getText().toString().trim());
    Log.v("textview2",textview2.getText().toString().trim());

}
