Textwatcher doesn't recognize space

I am trying to filter a gridview and for that I am entering the data in an editbox. It works great except that when I insert a space character in editbox it somehow doesn't recognize it and the result set comes empty. Please help

Here is my editbox listener:

search.addTextChangedListener(new TextWatcher(){

    @Override
    public void afterTextChanged(Editable arg0) {}

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1,
            int arg2, int arg3) {}

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

        MainActivity.this.adapter.getFilter().filter(cs);

        }

});

I can't figure out the problem since it's working fine with other characters.

Try using trim(). Hope it will work for you.I know you will need to modify this code.but it may give you some idea.

search.addTextChangedListener(new TextWatcher(){

    @Override
    public void afterTextChanged(Editable arg0) {
        // TODO Auto-generated method stub

        MainActivity.this.adapter.getFilter().filter(search.getText().toString().trim());

    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1,
            int arg2, int arg3) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onTextChanged(CharSequence cs, int start, int before,
            int count) {
        // TODO Auto-generated method stub

        }

});

If this doesnt work try second option

search.addTextChangedListener(new TextWatcher(){

    @Override
    public void afterTextChanged(Editable arg0) {
       String result = s.toString().replaceAll(" ", "");
    if (!s.toString().equals(result)) {
         ed.setText(result);
         ed.setSelection(result.length());
         // alert the user
    }

    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1,
            int arg2, int arg3) {
        // TODO Auto-generated method stub

    }

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


        }

});

I prefer first option using trim() to string text.
