Question to ConstraintLayout

Hi,

I googled a lot on this but haven't found a solutions...

I want to use a ConstraintLayout in more or less all Views of my flex mobile
ViewNavigatorApplication.

How can I do this... I tried to extend ConstraintLayout with all columns
defined and setted it in the layout tag but this didn't work as well as
extending the view and defining everything in this... I always get:

Error: ConstraintColumn „COLUMN_1“ nicht gefunden.

...

What's the way I should go... can I resuse the layout somehow? Is there
somewhere a tutorial...

My code extending the view:

public class MyView extends View

public static var COLUMN_1:String = "COLUMN_1"
public static var COLUMN_2:String = "COLUMN_2"
public static var COLUMN_3:String = "COLUMN_3"

public function MyView ()

super();
var constLayout:ConstraintLayout = new ConstraintLayout();

var consColumn1:ConstraintColumn = new ConstraintColumn();
consColumn1.initialized(this, COLUMN_1);
consColumn1.width = 1/3;
constLayout.constraintColumns.push(consColumn1);

var consColumn2:ConstraintColumn = new ConstraintColumn();
consColumn2.initialized(this, COLUMN_2);
consColumn2.width = 1/3;
constLayout.constraintColumns.push(consColumn2);

var consColumn3:ConstraintColumn = new ConstraintColumn();
consColumn3.initialized(this, COLUMN_3);
consColumn3.width = 1/3;
constLayout.constraintColumns.push(consColumn3);

layout = constLayout;
