k the problem was you can only access views in the layout that is setContentView(r.layout); while my view was in different layout but i need it in activitymain so i moved it there the problem now is my mainActivity is a framelayout and although i have it working it is at the top of the screen covering menus i need to set constraints to place it under another layout so how do you do that??

my activity_main.xml is

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

</FrameLayout>
    <RelativeLayout
        android:id="@+id/equalizer_action_container"
        android:layout_width="match_parent"
        android:layout_height="130dp"
        android:layout_marginTop="130dp"
        tools:ignore="MissingConstraints">
        <com.chibde.visualizer.BarVisualizer
            android:id="@+id/visualizerBar"
            android:layout_width="match_parent"
            android:layout_height="133dp"
            android:layout_alignParentBottom="true" />
        
    </RelativeLayout>

</androidx.constraintlayout.widget.ConstraintLayout>

but everytime i go into gui it wont let me attach constraints i think cos it a framelayout it just places it at the top any hep would be great thanks
