android - Delay animation with Transitions framework -


i trying delay transition using transitionmanager.begindelayedtransition() support library.

i want use autotransition make linearlayout appearing/disappearing. animation works expected, except not delayed.

transitionmanager.begindelayedtransition(rootviewgroup, new autotransition().setstartdelay(1000)); linearlayout.setvisibility(view.visible);

the linearlayout in hierarchy of rootviewgroup of course.

i did testing, unfortunately not able make work. looks setstartdelay works on changebounds transition.

see following example (when set startdelay on first transition, delay won't work):

linearlayout = (linearlayout) findviewbyid(r.id.testlinearlayout); msceneroot = (viewgroup) findviewbyid(r.id.rootview); mstaggeredtransition = new transitionset();  transition first = new fade(fade.out); transition second = new changebounds(); transition third = new fade(fade.in); second.setstartdelay(1000).addtarget(linearlayout);  mstaggeredtransition.setordering(ordering_sequential); mstaggeredtransition.addtransition(first).addtransition(second).addtransition(third);  findviewbyid(r.id.testbutton).setonclicklistener(new view.onclicklistener() {     @override     public void onclick(view v) {         linearlayout.setvisibility(view.gone);         transitionmanager.begindelayedtransition(msceneroot, mstaggeredtransition);         linearlayout.setvisibility(view.visible);         relativelayout.layoutparams params = (relativelayout.layoutparams) linearlayout.getlayoutparams();         params.addrule(align_parent_end);         linearlayout.setlayoutparams(params);     } });

so suggest use this:

msceneroot.postdelayed(new runnable() {         @override         public void run() {             transitionmanager.begindelayedtransition(rootviewgroup, new autotransition().setstartdelay(1000));             linearlayout.setvisibility(view.visible);         }     }, 1000);

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
