onTextChanged(CharSequence s, int start, int before, int count) is called multiple times

Question

I am implementing addTextChangedListener on an EditText.

 tagNameEditText.addTextChangedListener(new TextWatcher() {

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

                }

                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {
                    last_text_edit = System.currentTimeMillis();
                    searchStringFilter = s.toString();
                    h.removeCallbacks(input_finish_checker);
                    already_queried = false;
                    h.postDelayed(input_finish_checker, idleTime);
                    // getFilter().filter(s.toString());
                }

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

Problem is whenever text changes in EditText it is called multiple times. But i want to call the OnTextChanged() only once after the text changes. Is there any way to achieve this ?. Any help is appreciated :)

Answer 1

Even I faced the similar problem. What i did was, i put a time say 1 second or 2 second. So i called the filter whenever user takes this much time/pause in typing.
