Android Filter Implementation Guide

To enable the filtering function on Android, you can follow these steps:

1. Design a user interface that includes all filtering options, which can be a pop-up window, a drawer menu, or a separate filtering page. This interface should consist of controls for all filtering criteria, such as checkboxes, radio buttons, dropdown menus, and so on.
2. Add a filter button or menu option on the main interface, when users click on it, the filter interface will be displayed.
3. In the filtering interface, users can choose the appropriate filtering criteria according to their needs. Once users have selected the filtering criteria, they can click the ‘confirm’ button.
4. In the click event of the confirm button, retrieve the selected filtering criteria from the user and filter the data based on these criteria.
5. Based on the filtering criteria, the displayed content can be updated by either reloading the data or directly filtering the data.

By following the steps above, you can enable filtering function on Android. During implementation, you can customize the interface and interactions based on specific requirements to enhance user experience.
