Hello,

I am making a list of friends in my app. but when i scroll that list its giving some UI issues like not showing all the images.

Have a look on below images.

THIS IS THE SCREEN

WHEN I SCROLL IT DOWN THEN

[arkadyz]

Could you please make images publicly available somewhere?  I can see nothing...

i think you are not setting the rowheight of the list properly. use

_list1.setrowheight(40); //like this

also the bitmap you are trying to use, see whether you are giving the proper image size while drawing.

if poss can you provide the snippet in which you are trying to draw the list. since i am not able to change the color of the list.(means by default it is coming blue).

thanks swapnil,

actually i m using horizontalfiledmanager here and adding components into that like images, labels, but as i have seen on the blog that we cant change the background color of managers. thats why here i m using the arrow image.

the image is proper and i m not resizing it. but i dont know why this blurring is cmng.

Code :

public class CustomVertical extends VerticalFieldManager{

public CustomVertical() {
        super(VerticalFieldManager.USE_ALL_WIDTH | VerticalFieldManager.USE_ALL_HEIGHT | Field.FIELD_HCENTER | VerticalFieldManager.FOCUSABLE);
    }

protected void sublayout(int maxWidth, int maxHeight){
         Field field;
       //get total number of fields within this manager
       int numberOfFields = getFieldCount();
       int x = 60;
       int y = 2;
       for (int i = 0;i < numberOfFields;i++) {
           field = getField(i); //get the field
           setPositionChild(field,x,y); //set the position for the field
           layoutChild(field, maxWidth, maxHeight); //lay out the field
           y += 30;
       }
       
     maxWidth = Graphics.getScreenWidth();
     maxHeight = 50;
       
     setExtent(maxWidth, maxHeight);
    }
    
     protected void paintBackground(Graphics graphics)
        {        
            // Sets the BackgroundColor
            graphics.setBackgroundColor(Color.LIGHTGREY);
            
            // Clears the entire graphic area to the current background
            graphics.clear();
        }
    
    public void paint(Graphics graphics) {        
        graphics.setBackgroundColor(Color.RED);
        super.paint(graphics);
        
        graphics.drawBitmap(5, 5, 100, 100, Bitmap.getBitmapResource("girl.jpeg"), 0, 0);
        // Clears the entire graphic area to the current background
       // graphics.clear();    
    }

public VerticalFieldManager getFriendsList(String friendName, String status) {

        Bitmap arrow = Bitmap.getBitmapResource("chevron_right_black_15x22.png");

        CustomVertical customVerticalList = new CustomVertical();

        FontFamily fontfam[] = FontFamily.getFontFamilies();
        Font fon[] = new Font[2];
        fon[0] = fontfam[0].getFont(FontFamily.SCALABLE_FONT, 18);
        fon[1] = fontfam[0].getFont(FontFamily.SCALABLE_FONT, 13);

        LabelField User = new LabelField(friendName);
        LabelField Status = new LabelField(status);

        User.setFont(fon[0]);
        Status.setFont(fon[1]);

        // CustomVertical2 c2 = new CustomVertical2();
        customVerticalList.add(User);
        customVerticalList.add(Status);

        BitmapField add = new BitmapField(arrow, BitmapField.FOCUSABLE){
            
            protected boolean navigationClick(int status, int time) {
                // This is method will invoke when you click on your bitmapfield and you can write your piece of code here
                UiApplication.getUiApplication().pushScreen(new FriendProfileScreen());
                return true;
                }
            
        };

        DualFieldManager dualFieldmanager = new DualFieldManager(customVerticalList, add);

        return dualFieldmanager;
    }

Using like

// Dummy Data
        add(getFriendsList("Kristen", "On Call"));
        add(new SeparatorField());
        add(getFriendsList("Priya", "Available"));
        add(new SeparatorField());
        add(getFriendsList("Ayesha", "Available"));
        add(new SeparatorField());
        add(getFriendsList("Somya", "Available"));
        add(new SeparatorField());
        add(getFriendsList("Mapet", "On Call"));
        add(new SeparatorField());
        add(getFriendsList("Vonz", "Available"));
        add(new SeparatorField());

why don't you use a listfield? it would be the exact usecase of it imo.
