In my MainActivity i have 4 cardViews made as buttons every of them opens an Activity but now i would be able from settings to add "n" new buttons like one of yet created and set a path to open in BrowserView.

My main question is i have an xml file where i created the "CardView" that i use in main which has the ImageView, TextView so how can i programmatically set it in my MainActivity LinearLayout and even set different text in TextView for each "n" buttons.

Here is my MainActivity.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:background="#ffffff"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <android.support.v7.widget.CardView
        android:id="@+id/logo"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:cardCornerRadius="0dp"
        app:cardElevation="5dp"
        app:cardBackgroundColor="#00468a">

        <android.support.v7.widget.LinearLayoutCompat
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="#00468a"
            android:orientation="vertical">

            <ImageView

You inflate the new xml with View newView = LayoutInflater.from(context).inflate(resource_id, parentView); Cast the return result to whatever class you need it to be. Use the layout you want to put it in as the parent view. You can then use findViewById on the returned view to find subviews and set their values.

It is very easy

val inflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
val view = inflater.inflate(R.layout.view_from_xml, null)

viewToAddView.add(view)

It can be slightly easier than this. Use viewToAddView as the second parameter in inflate and it will add it for you. That's actually more correct, as your way may not set up the layout parameters correctly in some cases.
