Java 使用搜索筛选器应用搜索时，RecyclerView获取错误位置

我使用RecyclerView，并在其上实现了搜索过滤器，我在这里面临一个问题

在我搜索后，当我按下项目时，我得到了错误的位置，而不是一个我搜索过的位置，请帮助我解决这个问题

例如，项目编号2在搜索Android后命名Android位置进入编号1。。为什么会有这个问题。。多谢各位

MyAdapter.java

滤器

   TextWatcher mTextWatcher = 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 (s.toString().equals("")){
                initAdapter();
            } else {
                searchItem(s.toString());
            }
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    };

    private void initAdapter(){
        adapter.listItems.clear();
        for (int i = 0; i < 10; i++) {
            listItems.add(new RecyclerItem("Item " + (i + 1), "Welcome to Torisan channel, this is description of item " + (i+1)));
        }
        adapter.notifyDataSetChanged();
    }

    private void searchItem(String itemname){
        int resultCount = 0;
        adapter.listItems.clear();
        for (int i = 0; i < tempListItems.size(); i++){
            if (tempListItems.get(i).getTitle().contains(itemname)){
                listItems.add(new RecyclerItem("Item " + (i + 1), "Welcome to Torisan channel, this is description of item " + (i+1)));
                resultCount ++;
            }
        }
        if (resultCount == 0){
            showToast();
        }
        adapter.notifyDataSetChanged();
    }

    public void showToast() {
        // Set the toast and duration
        int toastDurationInMilliSeconds = 1000;
        mToastToShow = Toast.makeText(this, "No results found.", Toast.LENGTH_LONG);

        // Set the countdown to display the toast
        CountDownTimer toastCountDown;
        toastCountDown = new CountDownTimer(toastDurationInMilliSeconds, 1000 /*Tick duration*/) {
            public void onTick(long millisUntilFinished) {
                mToastToShow.show();
            }
            public void onFinish() {
                mToastToShow.cancel();
            }
        };

        // Show the toast and starts the countdown
        mToastToShow.show();
        toastCountDown.start();
    }
}

请用这个

for (int i = 0; i < tempListItems.size(); i++) {
    if (listItems.get(getAdapterPosition()).getName().equals(tempListItems.get(i).getName())) {
        int selectedPos = i;  //SelectedPos is that index
        break;
    }
}
