Should caution be exercised when implementing a Custom View containing a large amount of text when using RecyclerView?

Yes, caution should be exercised. Custom View with a large amount of text can negatively impact RecyclerView performance, especially during fast scrolling. This is because rendering and measuring complex or large text elements require resources and time.

Recommendations:

• Use ViewHolder to reuse Views.
• Optimize layout by avoiding excessive nesting.
• Cache text measurements if possible.
• Consider using TextView with hardware acceleration enabled and optimized drawing methods.

Example: if a Custom View contains a lot of multiline text, check whether scrolling is slow, and if necessary, simplify the display or split the text into multiple elements.
