Diff btw recycler view and listview

#1

can you please tell me some differences btw listview and recycler view so that i can know when to use either of them,and if we have listview what is the use of recycler view??

#2

Have you watched recyclerview and list view throughly ? If yes you would know the answer to the question. Let me know if that’s still unclear.

#3

I just got to know that recycler views are more efficient than list views and their implementation is also easy for complex object.Is there anything other than this i should know about them??

#4

How ther are efficient can you tell that ?

#5

In list view raw form,list item view get created everytime so there is heavy load on os but in recycler view the views get recycled and only data in them changed after first 4-5 views.Although we can get same functionality in list views too after making some optimization like making CourseViewHolder and efficiently using counterView

#6

I guess than you have your answer

#7

Yup,Sir can you tell me use of contraint layout,i mean why we need it and what are the types of constrains it provide??

#8

You don’t need it you can do almost everything using linear layout and frame layout

#9

Bdw it provides more 20 25 types of different constraints as far as i remember.

#10

what these constraint are ,i mean what type of constraint do they provide in our layout,related to dimension, position of views or anything else??

#11

You can think of them similar to relative layout nothing else.
