如何在Android Studio中创建最近使用过的列表

Question

Im new to app building and im building an application which stores a profile and data. i want to add an activity where i can display a list of the most recently viewed profiles. Where do i start???

Answer 1

When viewing profile add timestamp to it. And when displaying profiles sort them by timestamp you created.

Answer 2

You can get the timestamp when viewing profile, and store it to profiles table in an additional column in your database. Then when you getting the list of profiles just sort them by column timestamp and show in given way.

To access timestamp you can use next code snippet:

long timestamp = new Date().getTime();

Just call it when opening profile and store received value to the database if the value already exists - just update it.
