如何在这段代码上实现搜索方法？它成功地从服务加载数据，但我无法在此列表上实现搜索。

我已将其用作搜索过滤器的代码。我希望这有帮助 。

    yourEditText.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) {
            String Police No=yourEditText.getText().toString();

            ArrayList<YouDataModel> Filter=new ArrayList<YouDataModel>();

            for (DataModel data: leaveDatas) {
                if (data.getUserName().toLowerCase().contains(nameToSearch.toLowerCase()) || data.getUserName().toLowerCase().equalsIgnoreCase(nameToSearch.toLowerCase()) )
                {


                    filteredLeaves.add(data);
                }


            }

            leaves_adapter = new Leaves_Adapter(filteredLeaves, Activity.this);
            listView.setAdapter(leaves_adapter);

        }

        @Override
        public void afterTextChanged(Editable s) {


        }
    });
