Answer 1

I find working with filters not all that convenient.. How i do it is:

        ((EditText)findViewById(R.id.etSearch)).addTextChangedListener(new TextWatcher(){

        private boolean mCountIncreased;
        @Override
        public void afterTextChanged(Editable s) {

            if (s.toString().length() == 0){
                mDisplayedList.clear();
                mDisplayedList.addAll(mFullList);
                mListAdapter.notifyDataSetChanged();
                return;
            }

            if (mCountIncreased){
                mDisplayedList.clear();
                mDisplayedList.addAll(mFullList);
            }

            List toRemove = new ArrayList();
            for (Item item : mDisplayedList){
                if (someCondition)
                        toRemove.add(currency);
                }
            }

            mDisplayedList.removeAll(toRemove);
            mListAdapter.notifyDataSetChanged();
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            mCountIncreased = after <= count;
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {}

    });
}

Note that you'll have to change your adapter to work with the mDisplayedList instead of the mFullList.. and that's it.

This might give some overhead when your list contains ALOT of entries.. but i've worked like this with a list of +-300 items and i didn't notice anything.

Hope it helps, Vlad
