DrawerLayout open slowly

Question

I'm working on an app designed to use a DrawerLayout that contains a ListView, and i got an issue whit it . I'm using an ALCATEL IDOL MINI , API 17 to debug.On that phone , the drawer slide normally , even if the content is populated by views and information , also the scroll speed of the ListView is normal.but when i tested my app on another phone (Samsung Galaxy S3 API 19 and Nexus 5 API 21),the drawer slide very slowly with some lags and also the speed of scrolling the ListView inside is slow ,just when the content is populated by views and information. It doesn't make any sense because the S3 and Nexus 5 are more powerful .

Answer 1

I Finally resolved the problem , it was a background image issue , i used a HD image as background of the drawerlayout and also the ListView , now after i changed the background , the Drawer slide smoothly and items of the List are scrolled smoothly as well.
