Where are the primitive components that make up dynamic objects located?

In Android, primitive components that are part of dynamic objects (such as View or ViewGroup) are usually located within the view hierarchy. They are stored in memory as part of a View object, which can contain references to child components. When creating interfaces dynamically, these primitive components are created and added to containers (such as LinearLayout, RelativeLayout) programmatically, and their state is stored in the fields of the corresponding objects. Thus, primitive components are inside View objects and are managed by the system through the view hierarchy.
