You need to use an HorizontalFieldManager to put editfield and image on the same line. Read here http://www.blackberry.com/developers/docs/6.0.0api/net/rim/device/api/ui/container/HorizontalFieldManager.html and here: http://www.androidadb.com/class/ho/HorizontalFieldManager.html , a simple example showing how adding two buttons in an HorizontalFieldManager. Just substitute buttons with yor needed fields.

Or you can play with GridFieldMgr:

        GridFieldManager gridMgr_g = new GridFieldManager(1, 2, 0);
        gridMgr_g.setColumnProperty(0, GridFieldManager.FIXED_SIZE, screenWidth-myBitmapRes.width);
        gridMgr_g.setColumnProperty(1, GridFieldManager.FIXED_SIZE, myBitmapRes.width);

        gridMgr_g.add(new EditField());
        gridMgr_g.add(new BitmapField(Bitmap.getBitmapResource(myBitmapRes)));

        add(gridMgr_g);
