Hii,

I have created one sample application using tableLayOut Manager .i have added 5 images in array,but i am getting only first 2 images .and also i am not able to scroll it Horizontally .Hear is my code snippet.

public class TableDemo extends MainScreen {

	Bitmap[] bit = new Bitmap[5];
	int _columns;
	 public static final int USE_PREFERRED_SIZE = 3;
	public TableDemo(){
		
		
	bit[0] = Bitmap.getBitmapResource("1.jpg");
		bit[1] = Bitmap.getBitmapResource("2.jpg");
		bit[2] = Bitmap.getBitmapResource("3.jpg");
		bit[3] = Bitmap.getBitmapResource("4.jpg");
		bit[4] =  Bitmap.getBitmapResource("5.jpg");
		TableLayoutManager colFMgr = new TableLayoutManager(new int[]
		                                                              {
		        TableLayoutManager.USE_PREFERRED_SIZE,
		        TableLayoutManager.USE_PREFERRED_SIZE,
		        TableLayoutManager.USE_PREFERRED_SIZE,
		        TableLayoutManager.USE_PREFERRED_SIZE,
		        TableLayoutManager.USE_PREFERRED_SIZE
		    }, Field.FIELD_HCENTER|HORIZONTAL_SCROLL|HORIZONTAL_SCROLLBAR);
		    for(int i= 0;i < bit.length;i++)
		    {
		        colFMgr.add(new BitmapField(bit[i], Field.FOCUSABLE));
		    }
		    
		    add(colFMgr);
	}
	
}

 need your Suggetions.

thanks.

I'm not sure

USE_PREFERRED_SIZE

is the right thing to use, try

SPLIT_REMAINING_WIDTH

You might have to scale the Bitmaps to match the screen size you are using.

i have tried
for(int i= 0;i < bit.length;i++)
{
scalebitmap[i] = new Bitmap(242,120);

bit[i].scaleInto(scalebitmap[i], Bitmap.FILTER_LANCZOS);
colFMgr.add(new BitmapField(bit[i], Field.FOCUSABLE));
System.out.println("Bitmap image Size "+i+""+ bit[i]);
}
but still no effect...

Its not scrolling horizontally..........

Try adding USE_ALL_WIDTH to the style for the Manager.

Nothing is happened.can i try to use another constructor of tableLayoutManager?

I would recommend in fact that you review the TableLayoutManager code.  It is not too bad and a good example of a layout manager.  So have a look at it, perhaps even debug the sublayout method.  That method might be, because of your Manager structure, being called with a width set to the screen width.  And that would explain the problem you are having.  Anyway, have a play!
