BlackBerry ButtonField not found

wish of those help The error you are receiving indicates that your app is too large. In my experience there is a practical limit of around 5MB for an application, any more than this and you will run into these strange 'class not found' errors.
Try adding a smaller video file to see whether the problem goes away.

may help you . Using visual states indicator of the Field, and BackgroundFactory you can set Background for following visual states:
VISUAL_STATE_ACTIVE - Active visual state. The user is interacting with the field. VISUAL_STATE_DISABLED - Disabled visual state. There is no possible interaction with the field. VISUAL_STATE_DISABLED_FOCUS - Disabled, but focused visual state. The field is highlighted, but there is no other possible interaction with the field. VISUAL_STATE_FOCUS - Focus visual state. The field has focus (is highlighted). VISUAL_STATE_NORMAL - Normal visual state. There is no current interaction with the field.

code :

ButtonField bfTest = new ButtonField("Button Field");

Background commonBgOne = BackgroundFactory.createSolidBackground(Color.RED);
Background commonBgTwo = BackgroundFactory.createSolidBackground(Color.GREEN);

bfTest.setBackground(VISUAL_STATE_ACTIVE, commonBgOne);
bfTest.setBackground(VISUAL_STATE_DISABLED, commonBgTwo);
bfTest.setBackground(VISUAL_STATE_DISABLED_FOCUS, commonBgTwo);
bfTest.setBackground(VISUAL_STATE_FOCUS, commonBgOne);
bfTest.setBackground(VISUAL_STATE_NORMAL, commonBgTwo);

Border commonBorder = BorderFactory.createSimpleBorder(new XYEdges());

bfTest.setBorder(VISUAL_STATE_ACTIVE, commonBorder);
bfTest.setBorder(VISUAL_STATE_DISABLED, commonBorder);
bfTest.setBorder(VISUAL_STATE_DISABLED_FOCUS, commonBorder);
bfTest.setBorder(VISUAL_STATE_FOCUS, commonBorder);
bfTest.setBorder(VISUAL_STATE_NORMAL, commonBorder);

Hope that helps ListField does not support ButtonField instances on list rows. Screenshot you have provided does not show ListField instance. It is a combination of non-list fields and layout managers.
