Ich versuche, Animated ExpandableListview im ScrollView-Layout zu implementieren. Aber wenn ich eine Kategorie erweitere, funktioniert Scroll nicht. Wenn irgendeine Methode dafür ist, dann hilf mir bitte. Danke im Voraus

Dies ist mein XML-Code:

<ScrollView
        android:id="@+id/scroll_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/nav_header_container"
        android:overScrollMode="never"
        android:scrollbars="none">

        <LinearLayout
            android:id="@+id/ll_scroll"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <LinearLayout
                android:id="@+id/ll_home_category"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@drawable/layout_press_color"
                android:orientation="horizontal"
                android:padding="@dimen/standard_padding">


                <ImageView
                    android:id="@+id/item_header_image"
                    android:layout_width="25dp"
                    android:layout_height="25dp"
                    android:layout_centerVertical="true"
                    android:src="@drawable/ic_home" />

                <com.vrin.sga.uc.TextView_Open_Sans_Light
                    android:id="@+id/txt_category"
                    style="@style/Normal_Textview_White"
