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.

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);

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();
}
}

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:

Problems with OnItemClick on a custom ListView

I am using a custom ListView with a custom ArrayAdapter for my custom object. I fill my ListView with parsed data from a xml file. I am able to fill the ListView with these data but I want to switch to different activities depending on which item was clicked. I can show with
int position
which item was clicked but how can I retrieve for example the name of the clicked button?
My code:

Calling the getItem(int position) method on your adapter will get the DataPoint for that position, so change your onItemClick method to be something like:
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
DataPoint point = (DataPoint) parent.getAdapter().getItem(position);
String pointName = point.getName();
// TODO: Launch an activity with that name or something.
}

I solved it this way:
//Click on item in listview
devices.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
if(device_array.get(position).getResImage()==R.drawable.brightness){
Intent i0 = new Intent(ProjectView.this, Brightness.class);
i0.putExtra("Uniqid","From_ProjectView_Activity");
i0.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i0);
}
if(device_array.get(position).getResImage()==R.drawable.temperature_5){
Intent i0 = new Intent(ProjectView.this, Temperature.class);
i0.putExtra("Uniqid","From_ProjectView_Activity");
i0.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i0);
}
if(device_array.get(position).getResImage()==R.drawable.lamp){
Intent i0 = new Intent(ProjectView.this, Dimmer.class);
i0.putExtra("Uniqid","From_ProjectView_Activity");
i0.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i0);
}
if(device_array.get(position).getResImage()==R.drawable.lamp_switch){
Intent i0 = new Intent(ProjectView.this, OnOff.class);
i0.putExtra("Uniqid","From_ProjectView_Activity");
i0.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i0);
}
}
});

Use the view , you are using to inflate the data in listview.
as i was using a textview.
here what i used,
TextView tv = (TextView) v.findViewById(R.id.contacts_name);
String savedname = tv.getText().toString();
here v is the argument that we get in the method
public void onItemClick(AdapterView<?> arg0, View v, int position, long arg3)
{ // do something
}
