Problems with ListView inside a PopupWindow

Question

I have a ListView in a PopupWindow. The PopupWindow is initialized like this

    window.setContentView(root);
    wind         


        

Answer 1

I finally used a custom adapter to store the selected value and use it from there to mark it:

public class FileExplorerAdapter extends ArrayAdapter {

    /** File names */
    private List values = new ArrayList();

    /** Currently selected position */
    private int selected = -1;

    public FileExplorerAdapter(Context context, List values) {
        super(context, R.layout.explorer_row, values);
        this.values = values;
    }

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

        // I know that my layout is always a TextView
        TextView row = (TextView) convertView;
        if (row == null) {
            row = (TextView) ViewHelper.inflateViewById(getContext(),
                    R.layout.explorer_row);
        }

        // More code...

        // Set up the background for selected element
        if (selected == position) {
            row.setBackgroundColor(Color.LTGRAY);

        // Override background selector
        } else {
            row.setBackgroundColor(Color.TRANSPARENT);
        }

        // More code...

        return row;
    }

    /** This sets the selected position */
    public void setSelected(int position) {
        selected = position;
    }
}

And on the class that implements the OnItemClickListener for the associated ListView, I set up the currently selected item in the adapter.

@Override
public void onItemClick(AdapterView adapter, View v, int pos, long id) {
    FileExplorerAdapter fileadapter = (FileExplorerAdapter) fileList
            .getAdapter();
    fileadapter.setSelected(pos);
}
