ExpandableListView hides behind the Soft keyboard if i use adjustPan - Android

I am using adjustPan for windowSoftInputMode which is the requirement. Here how it seems like in Manifest file:

<activity android:name=".feature.dashboard.products.view.AddVariantsActivity"
            android:windowSoftInputMode="adjustPan" />

This is how my activity xml code look like

<?xml version="1.0" encoding="utf-8"?>
<layout 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">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/white">
        <ExpandableListView
            android:id="@+id/elvAddVariants"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:divider="@color/white"
            android:groupIndicator="@null"
            android:dividerHeight="@dimen/margin_medium_l"
            android:childDivider="@android:color/transparent">
        </ExpandableListView>
    </FrameLayout>
</layout>

Everything works fine but problem is that keyboard appears up on top of ExpandableListView so I cant see the last few entries if keyboard is visible. How can i fix this issue without changing android:windowSoftInputMode?
