It is very easy task.

You have to take one Vertical FieldManager then insert that VErticalFieldManager in a Screen.

Then take  3 Horizontal fieldManager one for each row so you can create 3 rows.

Then add  Image1 and text1 in horizontalfieldManager1 like that for second and third row then add that 3 horizontalFields in verticalField manager..

i take images and text dynamically from url and there are ten images and texts,

i try like this,for example

for(i=0;i<titleList.getLength();i++)

{

hfm.add(new Label(data));

hfm.add(bf);

vfm.add(hfm);

}

add(vfm);

it's not real code ,but logic like it.

it show me uncaught exception.

here hfm ->horizonal

and vfm->vertical

bf->bitmapfield

data->text

1) Are you getting IllegalStateException? This is normal if you are trying to manipulate anything on the Screen stack from a non-event thread. If it is another exception, post the details here.

2) For your layout you need a separate HFM for each text-image pair. Like this:

VerticalFieldManager vfm = new VerticalFieldManager(VERTICAL_SCROLL ...);
for (i = 0; i < length; ++i) {
  HorizontalFieldManager hfm = new HorizontalFieldManager();
  hfm.add(new Label(text[i]));
  hfm.add(new BitmapField(image[i]));
  vfm.add(hfm);
}
add(vfm);

 If you are adding all this to a MainScreen with "no arguments" constructor (it has VERTICAL_SCROLL enabled by default), you can skip vfm and add your HFMs directly to the screen.

thank u very much,

i solve my problem according ur guidence.

actually i do not declare Horizontalfield every time,

i just use globaly it .

[arkadyz]

The point is not to declare HFM every time (even though I did that in the loop) - the point is to create a new one for each "row" (new HorizontalFieldManager()).

thanks,

and also require to put space between image and text horizontally

u don't  add  void property in verticalField manager.

help me please.

Hi there, 

       Inorder to display a separator between the rows use SepatatorFiled in the ' for ' loop and 

for maintaining distance between the fields in rows use setMargin and setPadding methods.

       May be below code 'll b helpful.

VerticalFieldManager _vfm = new VerticalFieldManager(VERTICAL_SCROLL);
for (i = 0; i < length; ++i) {
  HorizontalFieldManager _hfm = new HorizontalFieldManager();
  _hfm.add(new LabelField(text[i]));
  _hfm.add(new BitmapField(image[i]));
  _hfm.setPadding(9,9,9,9);
  _hfm.setMargin(9,9,9,9);
  vfm.add(_hfm);
  vfm.add(new SeparatorField());
}
add(vfm);

use setPadding and setMarging method with fields and managers effectively inorder to achieve ur 

requirements.

regards,

Saran.

       Give kudos if this post is helpful..........

For Space between LabelField & Image, you can use either setPadding() method or add a LabelField with text as '   '(some spaces) .

And for Separators each time you have to create new instance of SeparatorField and add it to the VerticalFieldManager.
