Items not displaying orderwise in Recycler View

In my Recycler View not displaying the item orderwise routinely changing the items for each and every time while running the program.
How to display Order wise the items in Recycler View.

For sorting you need to Collection.sort method of Java and also you need to implement comparable interface for define your comparison.
CartItemoriginal implements Comparable {
public int compareTo(Object obj) { } }
Updated
public class CartItemoriginal implements Comparable<CartItemoriginal > {
private Float val;
private String id;
public CartItemoriginal (Float val, String id){
this.val = val;
this.id = id;
}
#Override
public int compareTo(ToSort f) {
if (val.floatValue() > f.val.floatValue()) {
return 1;
}
else if (val.floatValue() < f.val.floatValue()) {
return -1;
}
else {
return 0;
}
}
#Override
public String toString(){
return this.id;
}
}
and use
Collections.sort(sortList);

Dynamic ListView scroll TextView changed automatically

when i click + button increment the price and click - button decrease the price it's work perfectly but when i scroll listview the value of tvPrices (TextView) is changed.
What should i do for the stay increment price?
here is my adapter

In onclick, after you decrement the value call notifyDataSetChanged()
notifyDataSetChanged
but its a costly operation, since it refreshes complete list

How do I use onResume and onPause method when I am pressed back button

I have a custom adapter for recyclerview using json webservices. I had to parse the url one by one and show cardview using onscrolllistener(). My question is when I pressed the back button and after I open in recent app (that time onResume called) it will show only which url called at the time of onPause called. So how can I refresh the listview when I call onResume.

Sectioning date header in a ListView that has adapter extended by CursorAdapter

I am trying to build a demo chatting App.I want to show the messages with section headers as Dates like "Today","Yesterday","May 21 2015" etc.I have managed to achieve this but since the new View method gets called whenever I scroll the list.The headers and messages get mixed up.
For simplicity, I have kept the header in the layouts itself and changing its visibility(gone and visible) if the date changes.
Can you help me out with this? Let me know if anyone needs any more info to be posted in the question.

Missing data in Section list view in Android?

I am working with Section list view in Android to show Call details according to date.
Means under a particular date number of call details. But when I get 2 calls under the same date, the last date is visible only and the list does not show the rest of the calls of that date.
Calls under different dates are shown correctly but calls under same date are not shown correctly, only the last call is shown.
I am using the below code:
