android - Some layouts expanding slower than others when using LayoutTransition.CHANGING -
i have 19 horizontal linearlayouts arranged vertically within linearlayout. empty , onclick show text. animating layouts with
parentone.getlayouttransition().enabletransitiontype(layouttransition.changing); for reason first 7 layouts seem opening onclick little slower 8th. split second have asked others @ when open make sure i'm not crazy. post entire file huge , on maximum allowable text on this. here meat , potatoes. so, why layouts opening slower others? numbers 8-19 open instantly onclick , 1-7 have small delay noticeable.

well figured out. looks though processing issue. if had guess each time called method search through giant list of linearlayouts in oncreate method animation open it.
in oncreate method define crap ton of linear layouts such
linearlayout parentone = (linearlayout) findviewbyid(r.id.tfclayoutone); parentone.getlayouttransition().enabletransitiontype(layouttransition.changing); the fix:
i separated of them , placed them in respective onclick methods. now, when click them open faster other pages setup similarly, changing well. java methods were:
private boolean mopenone = false; public void toggleone(view view){ textview stepone = (textview)findviewbyid(r.id.stepone); imageview toggle = (imageview)findviewbyid(r.id.togglestepone); if(mopenone){ stepone.settext("step 1:"); toggle.setimageresource(r.drawable.open); } else{ stepone.settext("1. casualties altered mental status should disarmed immediately."); toggle.setimageresource(r.drawable.close); } mopenone = !mopenone; }
i have changed them to:
private boolean mopenone = false; public void toggleone(view view){ textview stepone = (textview)findviewbyid(r.id.stepone); imageview toggle = (imageview)findviewbyid(r.id.togglestepone); linearlayout parentone = (linearlayout) findviewbyid(r.id.tfclayoutone); parentone.getlayouttransition().enabletransitiontype(layouttransition.changing); if(mopenone){ stepone.settext("step 1:"); toggle.setimageresource(r.drawable.open); } else{ stepone.settext("1. casualties altered mental status should disarmed immediately."); toggle.setimageresource(r.drawable.close); } mopenone = !mopenone; } hope helps others!
