Listview inside scrollview does not scroll in lanscape mode

Question

I have to generate a dynamic listview in android. The listview is put inside a scrollview because I have other content too to display above the listview. Something like this :

Down part is the listview which is dynamically added. This all comes fine on a portrait mode on Samsung note5 but when I change the screen orientation to landscape the listview does not scroll. This could be because I have given wrap-content for the listview.

Please check my layout code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/rootLayout">
    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true"
        android:background="@color/gray25"
        android:id="@+id/scrollView"
        android:layout_above="@id/footer">
        <LinearLayout
            android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:id="@+id/mainLayout"
            android:background="@color/light_blue"
            android:paddingBottom="@dimen/_10sdp">
        <!--Top header-->
            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical"
                android:gravity="center_vertical"
                android:id="@+id/topheader"
                android:background="@drawable/dashboard_button"
                android:layout_marginLeft="@dimen/_5sdp"
                android:layout_marginRight="@dimen/_5sdp"
                android:layout_marginTop="@dimen/_5sdp"
                android:padding="@dimen/_5sdp">

            </LinearLayout>
        <!--middle portion-->


            <ListView
                android:id="@+id/RFIDList"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:transcriptMode="alwaysScroll"
                android:layout_marginTop="@dimen/_10sdp"
                android:background="@drawable/dashboard_button"
                android:layout_marginLeft="@dimen/_5sdp"
                android:layout_marginRight="@dimen/_5sdp"
                android:minHeight="@dimen/_50sdp" />

        </LinearLayout>
    </ScrollView>
<!-- Footer aligned to bottom -->
    <RelativeLayout
        android:id="@+id/footer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:gravity="center"
        android:background="@color/white">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            android:gravity="left"
            android:layout_centerInParent="true"
            android:layout_marginLeft="@dimen/_15sdp">               
        </LinearLayout>
    </RelativeLayout>
</RelativeLayout>

I cannot give fixed height to the listview because its items are generated dynamically. I tried to find the solution and also tried changing my listview to recyclerview but did not work. but Any help would be appreciated.

If you use RecyclerView use NestedScrollView instead of ScrollView and set

recyclerView.setNestedScrollingEnabled(false); after setting layout manager

for ListView see my answer over here

Use below method after listView.setAdapter(yourAdapter); as setlistViewHeight(listView,context);

Your problem will be solved.

public static void setlistViewHeight(ListView listView, Context context) {

    ListAdapter myListAdapter = listView.getAdapter();

    if (myListAdapter == null) {
        return;
    }

    int totalHeight = 0;
    for (int size = 0; size < myListAdapter.getCount(); size++) {

        View listItem = myListAdapter.getView(size, null, listView);
        if (listItem instanceof ViewGroup)
            listItem.setLayoutParams(new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT));

        WindowManager wm = (WindowManager) context
                .getSystemService(Context.WINDOW_SERVICE);
        Display display = wm.getDefaultDisplay();
        @SuppressWarnings("deprecation")
        int screenWidth = display.getWidth();
        int listViewWidth = screenWidth - 65;
        int widthSpec = View.MeasureSpec.makeMeasureSpec(listViewWidth,
                View.MeasureSpec.AT_MOST);
        listItem.measure(widthSpec, 0);

        totalHeight += listItem.getMeasuredHeight();
    }

    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight
            + (listView.getDividerHeight() * (myListAdapter.getCount()));
    listView.setLayoutParams(params);
    listView.requestLayout();
}
