问题是如何启动适当的Activity上下文来获得Fragment Manager？从可组合对象和Fragment之间的互操作性的Angular 来看，这可能吗？

    class Card @JvmOverloads constructor(
        context: Context, attrs: AttributeSet? = null
    ) : FrameLayout( // or any other View you want
        // don't forget to use context wrapper and to apply your own theme
        ContextThemeWrapper(
            context,
            context.resources.newTheme().apply { applyStyle(R.style.FantasyTheme, true) }
        ),
        attrs
    ), GamingHubView {
    
        override fun initialize(data: Map<String, Any>?) {
            // inflate a view or render views dynamically
    //        inflate(context, R.layout.view_card, this)
    
    
            val transaction: FragmentTransaction =
                (this.context as AppCompatActivity).supportFragmentManager.beginTransaction()
            transaction.replace(
                this.id,
                BlankFragment.newInstance("", ""),
                BlankFragment::class.simpleName
            )
            transaction.addToBackStack(null)
            transaction.commit()
        }
    
    
    }

    fun getActivity(context: Context?): AppCompatActivity? {
        if (context == null) return null
        if (context is AppCompatActivity) return context
        return if (context is ContextWrapper) getActivity(context.baseContext) else null
