将数据存储在ArrayList<ModelClass>中，然后可以过滤此arrayList的结果

您的全局变量

ArrayList<CustomerData> dataList = new ArrayList<>();
ArrayList<CustomerData> filteredList = new ArrayList<>();

假设您已经在dataList中接收到数据，则可以在TextWatcher()中添加EditText

searchET.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 (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            filteredList = indiaList.stream().filter(
                article -> article.getDate()
                                  .contains(s.toString()))
                                  .collect(Collectors.toList());
            adapter = new DataAdapter(filteredIndiaList);
            recyclerView.setAdapter(adapter);
            adapter.notifyDataSetChanged();
        }
    }

    @Override
    public void afterTextChanged(Editable s) {

    }
});

我正在使用JAVA 8，该方法仅适用于Android N +

您可以修改此

希望这会有所帮助！
