xml layout - Android pass parent view's 'pressed' state to child views -

there many question here on asking way prevent child view copying parents pressed or selected states. however, i'm asking other way around here :) - i've seen weird behavior in 1 of apps:

when running app on 4.0.4 device (api 15) behavior saw matched apparent default, is: parent forwards state down of child views.

when running same app without changes on higher api level (android 4.4) behavior changes: parent not forward state.

i introduced duplicateparentstate in xml layout relevant child views, not seem here.

is known 'issue' or planned change in behavior api 15 api >> 15?
how can make sure states forwarded across api levels?

if of / relevance here: subview want duplicate parents state custom imageview adds tintcolors - since behavior correct on 4.0.4 there should not mistakes in class?

public class incimageview extends imageview {      private int _tintcolor;     private int _highlightedtintcolor;     private int _selectedtintcolor;      public incimageview(context context, attributeset attrs) {         super(context, attrs);          this.setfocusable(true);         this.setclickable(true);          typedarray array = context.obtainstyledattributes(attrs, r.styleable.incimageview);          _tintcolor = array.getint(r.styleable.incimageview_tintcolor, getresources().getcolor(r.color.inc_tint));         this.setcolorfilter(_tintcolor);          _selectedtintcolor = array.getint(r.styleable.incimageview_selectedtintcolor, _tintcolor);         _highlightedtintcolor = array.getint(r.styleable.incimageview_highlightedtintcolor, _tintcolor);          array.recycle();     }      @override     public void setselected(boolean selected) {         super.setselected(selected);          this.setcolorfilter((selected ? _selectedtintcolor : _tintcolor));     }      @override     public void setpressed(boolean pressed) {         super.setpressed(pressed);          this.setcolorfilter((pressed ? _highlightedtintcolor : (this.isselected() ? _selectedtintcolor : _tintcolor)));     } } 

i found solution:

if have @ imageview subclass above, in constructor clickable & focusable set true.

turns out mistake. parent won't forward state when child clickable. - still not explain why above code works on 4.0.4 breaks on 4.4

anyway, leaving clickable & focusable = false solves problem.
