Add Search for Crew and Cast

[spipau]

Adds a search icon to the crew and cast list to filter for name and role.

• Add new menu xml entry for people
• Add search menu icon to Toolbar
• Migrate people adapter from ArrayAdapter to BaseAdapter
• Implement search and filter by using .contains() for name and description
• Handle empty state

Thanks! However, these changes have such fundamental issues that I wonder if this was created using an LLM coding agent?

If you wrote this yourself, I suggest having a look at for example https://developer.android.com/topic/architecture#common-principles

Hi, I would like to express my graditute as I use your application since more than a decade! 🙏

When implementing this PR I had a nostalgic blast from the past as the architecture used in this part of the applications is ancient. It uses a List, not even a RecyclerView – something I havn't seen since ~2012? 😄
I tried a bit the Gemini Agent, but rewrote most of it. I did not want to reimplement the whole View/Activity and had some fun programming like in the old days. You'd like to rather see a full rewrite?

My main concern is about architecture, not APIs. As you seem interested in working on this, I'll go into details. It's a learning exercise for me. But it's OK if you drop this, I can get to this myself at some point.

The main issue is that the adapter class is used to modify the data when it's purpose is just to bind data to the UI. There is an existing view model class that's responsible for obtaining and keeping the current state of the credits data. UI events, like the search, should trigger logic in the view model. Which then should update the credits data.

But there are many other small things to improve like

• sending of UI events through ViewModel (related to above) instead of FragmentManager to Fragment
• using localized string resources instead of concatenation of existing string resources
• correctly updating copyright statements
• using modern options menu APIs and search view components
• dropping unrelated formatting and code changes in PeopleAdapter (constructor, view holder)
