Android ขอวิธีการ Intent ไปใช้ใน Edittext ใน onTextChanged ทีครับ

name = getIntent().getStringExtra("mk_name");
txtSearch.setText(name);

private void Search() {
        txtSearch.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) {
                if(txtSearch.length() !=0){

                    array_search = new ArrayList<Item>();

                    for (int i = 0; i < array.size(); i++){
                        if(array.get(i).getTitle().toLowerCase().contains(s)){
                            Item items = new Item();
                            items.setTitle(array.get(i).getTitle());
                            items.setDes(array.get(i).getDes());
                            items.setOpenn(array.get(i).getOpenn());
                            items.setClose(array.get(i).getClose());
                            items.setImage1(array.get(i).getImage1());
                            items.setImage2(array.get(i).getImage2());
                            items.setImage3(array.get(i).getImage3());
                            items.setImage4(array.get(i).getImage4());
                            items.setImage5(array.get(i).getImage5());
                            items.setImage6(array.get(i).getImage6());
                            array_search.add(items);

                        }
                    }
                    ListSearch();
                }else {
                    ListNormal();
                }
        }

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


private void ListSearch(){
        adapter = new Adapter(this,array_search);
        listView.setAdapter(adapter);

     
    }
