Understanding the Issue: Customizing TextView Selection in Nested RecyclerViews
In the world of Android development, dealing with complex layouts often comes with its share of challenges. One common scenario is when you have a NestedScrollView that contains a RecyclerView, each item in the RecyclerView having multiple views such as TextView and ImageView. The need to customize text selection actions in such layouts can sometimes lead to unexpected issues. In this guide, we'll delve into the specific problems arising from customizing the TextView selection action mode callback and explore effective solutions.
The Problem Breakdown
The developer faced several issues when attempting to customize the TextView selection action using Kotlin extension methods. Here are the problems identified:
Menu Not Hiding After Click: The action menu remained visible after a menu item was clicked, disrupting the user experience.
Scrolling Issues: Users experienced unwanted scrolling behavior, where the view would unintentionally snap back to the previously selected text.
Incompatibility with MIUI ROM: The custom action mode was not functioning correctly on devices using MIUI ROM, suggesting potential compatibility issues.
Initial Approach
The developer's approach involved creating a custom ActionMode.Callback associated with the TextView. Here's a simplified version of the callback method:

While this set up allowed for some functionalities, it did not adequately address the existing issues.
Solutions to the Problems
Fixing the Action Mode Menu Visibility
The first issue regarding the menu not hiding can be resolved by finishing the action mode once a menu option is clicked. This ensures that the user is returned to the standard interaction mode.
Here’s the adjusted code snippet:

Improving Scrolling Behavior
Next, to address the scrolling issues, it's crucial to implement additional logic to manage focus when dealing with nested scrolling views. This can prevent unwanted jumps during user interactions.
An effective quick fix is to override the requestChildFocus method in your custom NestedScrollView. This can prevent the focus issue altogether:

Final Thoughts on Compatibility Issues
Although specific issues with MIUI ROM might require tailored solutions or workarounds, frequently updating the libraries and checking device-specific documentation can offer insights into compatibility challenges. Continuing to monitor user feedback on various ROMs will enhance future customization options as well.
Conclusion: Effective Customization of Text Selection in Android
Customizing the selection actions for TextView inside nested RecyclerView components can be challenging, but with the right approach, many of these issues can be effectively resolved. Implementing the adjustments discussed here will not only improve user experience by ensuring smooth interactions but also pave the way for more robust Android applications.
