Android : How to programmatically set layout_constraintRight_toRightOf “parent”

Question

I have a view in ConstrainLayout as follows.

Answer 1

Use id

class MyLayout(context: Context) : ConstraintLayout(context) {

    fun show() {
        val view = ImageView(context)
        addView(view)
        val params = view.layoutParams as ConstraintLayout.LayoutParams
        params.height = 100 
        params.width = 50
        params.rightToRight = id
        view.requestLayout()
    }
}
