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.
Code:
final CustomLinearLayoutManagercartpage layoutManager = new CustomLinearLayoutManagercartpage(CartItems.this, LinearLayoutManager.VERTICAL, false);
recyleitems.setHasFixedSize(false);
recyleitems.setLayoutManager(layoutManager);
cartadapter = new CartlistAdapter(cart, CartItems.this);
Log.i(String.valueOf(cartadapter), "cartadapter");

myView.setVisibility(View.GONE);
cartadapter.notifyDataSetChanged();

Thanks in Advance.

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
public class ListAdapter extends BaseAdapter {

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

howt to solve the getview's position is cofusition in the baseadapter in android

Above is the code of getview, I was in the use of staggeredgridview Etsy ，when I scroll the screen,this problem is occurs, a time when the position is out of confusion, as if the location of the position did not be remembered.
The following is a screenshot of position getview：

This issue comes only if you are not controlling getCount() and getItem() methods. Make sure that you are returning your list size as in getCount() like this :
#Override
public int getCount() {
return list.size();
}
and getItem() as :
#Override
public SetterGetterClassName getItem(int position) {
return list.get(position);
}

This is my complete code :
enter code here

//private HashMap<Integer, View> viewMap;

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.

How can I proceed in these two scenarios?
EventParsingClass EPSP= ??? and
EPSP.getid= ??

fetch[0]="XXX"
fetch[1]="YYY"
fetch[2]="ZZZ"
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), fetch[position] + "Clicked",
Toast.LENGTH_LONG).show();
}
just declare fetch[position] to get the value of clicked item. hope this will give you some solution.

Use int position to find out values from your data list (array list or what ever you used).
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), EPSP.getid(position) + "Clicked",Toast.LENGTH_LONG).show();
}

EventItem item = (EventItem) parent.getItemAtPosition(position);
Now you have a hold of EventItem. So you can start using the get methods of your EventItem class in order to get whatever you want from it.

I got the solution:
EventParsingClass new_method(int value) {
int item_count = 0;
for (int i = 0; i < arrayOfEventDescription.size(); i++) {
ArrayList<EventParsingClass> Arraylist_for_loop = arrayOfEventDescription
.get(i);
item_count++;
for (int j = 0; j < Arraylist_for_loop.size(); j++) {
if (value == item_count) {
return Arraylist_for_loop.get(j);
}
item_count++;
}
}
return null;
}
And call it from here:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
EventParsingClass newObject = new_method(arg2);
if (newObject == null) {
} else {
Log.d("Generated Value Id : ", "" + newObject.getId());
Toast.makeText(getApplicationContext(),
"Item Clicked" + arg2 + "-----" + newObject.getTitle(),
Toast.LENGTH_LONG).show();
}
}
