hello,

I am not getting any results from this code please check the code.

public class CMyFamilyFeature3 extends iFarmersScreen {
    int DISPLAY_WIDTH = Display.getWidth();
    int DISPLAY_HEIGHT = Display.getHeight();

    Vector vector1 = new Vector();
    Vector vector2 = new Vector();
    
    public CMyFamilyFeature3(){
    
        super(NO_VERTICAL_SCROLL|USE_ALL_HEIGHT);
        
        vector1.addElement("Life in A NutShell            04:08");
        vector1.addElement("Life - Tara Newby Story");
        vector1.addElement("Life - Mark Smith Story");
        
        vector2.addElement("This short video answers the basic questions with regard to the needs,specifications and the type of life insurance needed for a consumer.");
        vector2.addElement("Tara Newby describes her tragic experience with regard to the needs,specifications and the type of life insurance needed for a consumer.");
        vector2.addElement("In this short video Mark Smith Illustrated with regard to the needs,specifications and the type of life insurance needed for a consumer.");

         ListField listfield = new ListField();
           listfield.setBackground(BackgroundFactory.createSolidBackground(0x00FFFFFF));
            listfield.setRowHeight(80);
            myListFieldCallBack callback = new myListFieldCallBack();
            listfield.setCallback(callback);
         //   listfield.setChangeListener(buttonSet);
            listfield.setSize(vector1.size());
          add(listfield);
    }
    
}

ListFieldCallback class

public class myListFieldCallBack implements ListFieldCallback{
    
    int DISPLAY_WIDTH = Display.getWidth();
    int DISPLAY_HEIGHT = Display.getHeight();
    private static final int LEFTMOST = 0;
    Vector vector1 = new Vector();
    Vector vector2 = new Vector();
    
    public void drawListRow(ListField listField, Graphics graphics, int index,
            int y, int width) {
        int xpos = LEFTMOST;
        int ypos = y+30;
        String text = (String)vector1 .elementAt(index);
        String text1 = (String)vector2.elementAt(index);
        Font ourBoldFont = ourFont.derive(Font.BOLD);
        graphics.drawText((char) text.indexOf(index), 110, y, 0, width);
        graphics.drawText(text1, xpos+15+90, ypos);
        graphics.drawRect(0, ypos-30, width, 0);
}
public Object get(ListField listField, int index) {
    //return vector1.elementAt(index);
    return listField;
}

public int getPreferredWidth(ListField listField) {
    return DISPLAY_WIDTH;
}

public int indexOfList(ListField listField, String prefix, int start) {
    return -1;
}
}

is this code is right or any thinking missing.

please check this code and give me solution for this..

thanks

in your draw callback you create new vectors (1&2) which are empty. i would also suggest that you use only a single vector and create a bean class for your attributes.

Are you using two ids and repeating your problems?  That's is not playing fair for a number of reasons.  Please just use one id and ask questions once.
