ConstraintLayout version: Androidx


In working with ConstraintLayouts I tried to build a child ConstraintLayout that matches the parent size. When I used androidx it did not size appropriately when I programatically set params:

ConstraintLayout userEducationLayer = (ConstraintLayout) layoutInflater.inflate(R.layout.photos_lens_avs_education_highlight_layer, /* root= */ null, /* attachToRoot= */ false);
    // Make layer span entire parent.
    ConstraintLayout.LayoutParams layoutParams = new ConstraintLayout.LayoutParams(LayoutParams.MATCH_CONSTRAINT, LayoutParams.MATCH_CONSTRAINT);
    layoutParams.leftToLeft = LayoutParams.PARENT_ID;
    layoutParams.topToTop = LayoutParams.PARENT_ID;
    layoutParams.rightToRight = LayoutParams.PARENT_ID;
    layoutParams.bottomToBottom = LayoutParams.PARENT_ID;
    userEducationLayer.setLayoutParams(layoutParams);


XML:
<ConstraintLayout id=container>
  <ConstraintLayout
      id=child
      width=0dp height=0dp constrainLeftTopRightBottom=parent>
  </ConstraintLayout>
</ConstraintLayout>


But it did work when I used support ConstraintLayout.
