A lot of questions seem to be of the form "What's the best way / another way to provide functionality X on platform Y?". See, for example, Alternative for circles page indicator for many pages?
My go-to in these cases is to refer to the official UX style guides for that platform (in this case Android, but in the last couple of days I've also referenced Windows and iOS documentation). I actually worked on Windows for a couple of years, during which time I developed a very strong appreciation for (a) the level of thought that goes into building these guidelines, and (b) how easily a UX can fall apart when people just make up their own way of doing things that have well-understood solutions.
But that raises a couple of meta questions:
- Is that a legitimate use of this site? Is the intent that I provide an original answer rather than merely cite some existing source?
- Is it fair to assume that, when a question is asked, the asker already has some reason why they're not using the official guidelines as a starting point? My inclination is to say "no", but it feels cynical to assume that the asker didn't do due diligence.
How much legwork should be done on behalf of the asker? Some possibilities:
- Just link to the guidelines and say "figure it out yourself"
- Link to the appropriate page and say "read section Z"
- Copy/paste the relevant sections (potentially along with images) into the answer
- Provide a summary of the relevant guidance
- Provide an additional level of analysis on top of the guidance
