constraintlayout 1.1.1 not work well in listview

[TChengZ]

i recently update the constraintlayout from 1.0.2 to 1.1.1，i found that when you scroll the listview(also expandablelistview) it run very slowly, once you change the constraintlayout to 1.0.2, the listview runs very good,i don't know how to convert this problem to the develper of ConstraintLayout，so i write it here.....
