I searched on google but I didn't understand how to implement in this ?

You need to pass the string that is being typed in editext to your filter

youradapter.getFilter().filter(s);
youradapter.notifyDataSetChanged();

Override getFilter() and performFiltering(params) in your adapter class

  @Override
  public Filter getFilter() {
   return new Filter() {
        @Override
       protected void publishResults(CharSequence constraint, FilterResults results)                  {
           if (results != null && results.count >= 0) {
              //set reeulst
           } else {
               // set original values
           }

           notifyDataSetInvalidated();
       }



      @Override
       protected FilterResults performFiltering(CharSequence constraint) {
           FilterResults result = new FilterResults();
           if (!TextUtils.isEmpty(constraint)) {
                  ArrayList<type> foundItems = new ArrayList<type>();
                       //do something
                       //filter resutls 
                 }

               result.count = foundItems.size();//search results found return count
               result.values = foundItems;// return values

           else
           {
               result.count=-1;// no search results found
           }
              return  result;
      }

Edit :

Heres's the link of the working code

Search in ListView with EditText

I don't know if someone will code for you. But if you try you should be able to make changes to implement the same in your code..

enter image description here

you need to extend arrayadapter than baseadapter. http://developer.android.com/reference/android/widget/ArrayAdapter.html. ArrayAdapter a concrete BaseAdapter that is backed by an array of arbitrary objects. Check the link in the answer above. — Raghunandan, Apr 12 '13 at 07:05
show what you have implemented along with logcat by editing your question. The sample in the link works and i have tested it on my device — Raghunandan, Apr 12 '13 at 07:42
please join this chat http://chat.stackoverflow.com/rooms/24164/discussion-between-rohit-and-tushar — , Apr 12 '13 at 07:53
m too close , please see this http://stackoverflow.com/questions/6492214/custom-filtering-arrayadapter-in-listview, but in this have 2 lists in my case what i do please give hint — , Apr 12 '13 at 10:21
now i have started bounty on my question, if u can give answer then please give, otherwise its ur choice @Raghunandan — , Apr 15 '13 at 10:04
its not about choice. I have given a working code that you can implement. you should modify according to your needs. If someone can give a working code by modifying yours they will be doing your job. — Raghunandan, Apr 15 '13 at 10:15
i have totally implemented this http://www.mysamplecode.com/2012/07/android-listview-custom-layout-filter.html , but this is not working, i have taken new project for this that is also not working — , Apr 15 '13 at 10:37
What is the exact problem for which you want the solution? Just saying it is not working won't help. Find out what problem you are facing post the same. — Raghunandan, Apr 15 '13 at 11:43

Rohit - Sorry, but at a glance, I see a number of potential problems. Without time to build and run your code, I can only guess about your specific requirements. I'll address the first two opportunities for re-factoring. My gut thinks you'll find the answer in the process.

First, you are calling a method called, "showList()" before your activity has initialized. (In my opinion, you should be calling this method later. For example, in onResume.)

Then you are creating local reference variables which will not be in scope after onCreate runs (which occurs one and only one time per instance).

BTW, I find this sort of problem much easier to solve when inline class definitions (e.g. new View.OnClickListener) resolve to a proper, named class and/or instances of the class are member variables. If such changes might create memory management issues, you can optimize after your program is working as a user would expect.

Good luck!
