Trying to put a search functionality in my application

Hi, guys! First of all, I'm newbie! I'm trying to create a search functionality (Search BY CITY) in my application. But something is wrong! It don't work!
The error message is: 'The method filter(String) is undefined for the type BinderData'
adapter.filter(text);
Could someone help me in details? I included the "TextWatcher" function in my main activity (WeatherActivity).
This is my code:
WeatherActivity
public class WeatherActivity extends Activity {

Filter ListView data

I am working on an App where data is read from XML, then based on the data, It creates an ListView and clicking on any item in ListView it opens another activity with details. I am trying to implement search functionality in the ListView, below is my code, I don't know how ti implement Search, I tried many ways but none of them worked. Any help is highly appreciated. Thanks in advance.
public class BrowseActors extends Activity {

Search will be implemented on original data source, it could be XML/JSON/database or anything else.
You're using "position" parameter for search, I think you can use the View view parameter.
Just keep a hidden field in the ListView row, and map it with some sort of primary key.
When OnClick event occurs, you can then get the row layout from view and do a findViewByID() call to get your hidden control. From the value of that control, you can call a back-end web service or run an x-path query or anything you want.

Insert new data in Custom Adapter and update list

I have an list with an custom adapter, and upon refresh I want to add new data to be displayed(if any available).
But the list isn't being update. I tried all the methods with notifyDataSetChanged for the adapter but it's not updated.
Please help. I lost so much time with this and I feel like I'm loosing my mind with this one.
Here is the code:

}
}
When I request new data(refresh), I add the new data in my object (the same way I do the first time):
FeedItemParser.addItem(new FeedItem(
id,
from_id,
from_category,
from_name,
message,
null, // Will be gotten through another request
null,
privacy_value,
type,
status_type,
created_time,
updated_time,
likes,
comments));
After that I call
ListView actualListView = mPullRefreshListView.getRefreshableView();
// Need to use the Actual ListView when registering for Context Menu
registerForContextMenu(actualListView);
// Sort the list before displaying
Collections.sort(FeedItemParser.FEEDS, Comparators.CREATED_TIME);
// Notify list adapter to update the list
customAddapter.notifyDataSetChanged();
SOLUTION
Based on the recommendations of #Selvin I have managed to update my list after adding more data. Basically I changed my adapter(I'm not using an filtered list anymore, but I'm directly using my custom objects). And after I add new Object, I update the list by calling notifyDataSetChanged() on the existing adapter.
I have also update my code, maybe it will help someone else that is stuck is this situation.
Thanks again #Selvin.

Getting only the last item data from hashmap arraylist

I have parsed json data in which there is a main json array and it contains sub json array. But the main json array not containing the sub json array in every item. So i have parsed all the data accroding to it. and i am getting perfect data from it. But the problem is that the main json array data is displaying in listview and after click on list view item the sub json array is display accroding to main json array item but its only get the last element of sub json array from hash map array list. So i can't get proper way to display so please find out some standard solution.
Here is My Code

you should have to put new HashMap inside your current HasHMap so you can get subcategories items for particular index.
see this for how to use nested HashMap? and use it in subcategories loop.
i am using ArrayList of getter setter class to bind the data. so if you can convert your code into arraylist and edit the question that will be a great..
and see below code

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:
