Supposed i search "C" from given list where list item is as follows "A","B","C","D","CC", and got the correct search result but once making the click on search item, It returning the wrong item position.

Here Edittext addTextChangedListener :

edtSearch.addTextChangedListener(new TextWatcher() {

            public void onTextChanged(CharSequence s, int start, int before,
                    int count) {
                adapter.getFilter().filter(s);
                adapter.notifyDataSetChanged();

            }

            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {

            }

            public void afterTextChanged(Editable s) {
            }
        });
    }

    @Override

        if (position == 0) {
            Intent int0 = new Intent(getApplicationContext(), Admincost.class);
            startActivity(int0);
        }

        if (position == 1) {
            Intent int1 = new Intent(getApplicationContext(), Affinity.class);
            startActivity(int1);
        }
        if (position == 2) {
            Intent int2 = new Intent(getApplicationContext(), Analyse.class);
            startActivity(int2);
        }

        if (position == 3) {
            Intent int3 = new Intent(getApplicationContext(),
                    ApprasalCosts.class);
            startActivity(int3);
        }
        if (position == 4) {
            Intent int1 = new Intent(getApplicationContext(), Assessment.class);
            startActivity(int1);
        } }
    }
}

Change your onItemClick to:

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int position,
            long arg3) {
        // TODO Auto-generated method 

        if (((String)adapter.getItem(position)).equals("Admin Cost")) {
            Intent int0 = new Intent(getApplicationContext(), Admincost.class);
            startActivity(int0);
        }
          .........................

    }

When you filter your list, items get rearranged and thier position change so navigate to next activity based on the value on that position instead of position.
