Hi, recently i was learning on how to make custom views and i'm found out of the resources which using the method to inflate other views(from other xml activity). after trying it out to referencing the custom views in activity_main.xml in form of <com.test_project.library.buttons.TestButton/> , it did works perfectly, but i found out that i cannot override the text value because the android:text doesn't appear from suggestion.
is this because the effect from inflating the views? or there is something that missing from the custom views class that i didn't declare it first so i cannot put text value in activity_main.xml ?

the code of the custom views class

class TestButton : RelativeLayout {

    constructor(context: Context) : super(context) {
        initView()
    }

    constructor(context: Context, attr: AttributeSet? = null) : super(context, attr) {
        initView()
    }

    constructor(
        context: Context,
        attrs: AttributeSet?,
        defStyleAttr: Int
    ) : super(context, attrs, defStyleAttr) {
        initView()
    }

    private fun initView() {
        val rootView = (context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater)
            .inflate(R.layout.activity_button_default, this, true)
    }
}

The android:text will only be available, by default, if your custom view is a subclass of TextView . In your case, you extend from the RelativeLayout thus have no access to the xml attributes of the TextView.

1 way to fix this is by adding custom attributes to your custom view. See this post for more information.
