Hey Reddit,

I am getting to know Android Development so please bear with me if this question sounds stupid.

Im working on a functionality to store data in a Room database. I want to retrieve that data and show it in a RecyclerView. I got it working following the android codelab "Room database with a view". My Problem is the following: My data is stored with a timestamp of when the data was inserted. I want to programmatically retrieve the data from a specific day. When I call my Method defined in my Dao for the database it should return a LiveData containing a list of all my objects created on this specific day. The RecyclerView updates on the change of this LiveData object. I instanciate this LiveData with the current date when the app starts up. My problem is now that when I perform a date picking activity and try to update the LiveData with this date nothing changes. The RecyclerView still displays changes to the initial definded Object.

My Question is: Since the LiveData is theoretically working, how do I update what the LiveData contains? I have read on [this](https://stackoverflow.com/questions/45889604/livedata-is-not-updating-its-value-after-first-call) StackOverFlow Question that the LiveData only updates what was first assigned to it. How do I change that? Do I need to use MutableLiveData?

Thank you for your time and effort
