class tasklistfield extends mainscreen implements listfieldcallback {          private vector rows;          private bitmap p1; listfield list;          tablerowmanager row;          public tasklistfield() {           super();           list=new listfield() {                protected void drawfocus(graphics graphics, boolean on) {               }  };           list.setrowheight(40);           list.setemptystring("hooray, no tasks here!", drawstyle.hcenter);           list.setcallback(this);            p1 = bitmap.getbitmapresource("res/images/10.png");  rows = new vector();            (int x = 1; x < 13; x++) {             row = new tablerowmanager();              labelfield task = new labelfield("" + string.valueof(x),              drawstyle.ellipsis);    row.add(task);            row.add(new bitmapfield(p1));   rows.addelement(row);           }           list.setsize(rows.size()); add(list);          }           // listfieldcallback implementation          public void drawlistrow(listfield listfield, graphics g, int index, int y,            int width) {            tablerowmanager rowmanager = (tablerowmanager) rows             .elementat(index);           rowmanager.drawrow(g, 0, y, width, list.getrowheight());          }           private class tablerowmanager extends manager {           public tablerowmanager() {            super(0);           }   public void drawrow(graphics g, int x, int y, int width, int height) {             layout(width, height);              setposition(x, y);              g.pushregion(getextent());             // paint manager's controlled fields.            subpaint(g);             g.setcolor(0x00cacaca);            g.drawline(0, 0, getpreferredwidth(), 0);             // restore graphics context.            g.popcontext();           }             protected void sublayout(int width, int height) {             int preferredwidth = getpreferredwidth();              field field = getfield(0);            layoutchild(field, 30, 30);            setpositionchild(field, 0, 0);             field = getfield(1);            layoutchild(field, 40, 25);            setpositionchild(field, 120, 10);   setextent(preferredwidth, getpreferredheight());           }            // preferred width of row defined list renderer.           public int getpreferredwidth() {            return graphics.getscreenwidth();           }            // preferred height of row "row height" defined in           // enclosing list.           public int getpreferredheight() {            return list.getrowheight();           }          }           public object get(listfield listfield, int index) {           // todo auto-generated method stub           return null;          }           public int getpreferredwidth(listfield listfield) {           // todo auto-generated method stub           return 0;          }           public int indexoflist(listfield listfield, string prefix, int start) {           // todo auto-generated method stub           return 0;          } 

the image path not necessary put

p1 = bitmap.getbitmapresource (" res/images/10.png "); 

only needs

p1 = bitmap.getbitmapresource (" 10.png ");
