There's no constructor in your class that lets you do this:
ImageButtonField ImageButtonField bitmapField = new ImageButtonField(Bitmap.getBitmapResource("pimdemo_jde.png"), Field.FIELD_BOTTOM);
The constructor that you're trying to use requires a Bitmap instance and a long primitive (for Field.FIELD_BOTTOM). You should add a constructor with the following signature for your code to work:
public ImageButtonField (Bitmap bitmap, long style){
super(bitmap, style);
}
