Answer 1

Try the below example: Layout :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:weightSum="3" >

    <ListView
        android:id="@+id/list2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@drawable/face"
        android:cacheColorHint="#00000000" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:layout_weight="1"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Header"
            android:visibility="visible" />

        <ListView
            android:id="@+id/list"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/background"
            android:cacheColorHint="#00000000" />
    </LinearLayout>



</LinearLayout>

In your class

 ListViewAdapter arrayAdapter = new ListViewAdapter(this, values);

            listview.setAdapter(arrayAdapter);

        ListViewAdapter arrayAdapter2 = new ListViewAdapter(this, values2);

            listview2.setAdapter(arrayAdapter2);

Add these two lines in onCreate with your listview:

Utility.setListViewHeightBasedOnChildren(listview);
        Utility.setListViewHeightBasedOnChildren(listview2);

Create a inner class in your Activity:

//Test scrollview custom
    public static class Utility {
        public static void setListViewHeightBasedOnChildren(ListView listView) {
            ListAdapter listAdapter = listView.getAdapter(); 
            if (listAdapter == null) {
                // pre-condition
                return;
            }

            int totalHeight = 0;
            for (int i = 0; i < listAdapter.getCount(); i++) {
                View listItem = listAdapter.getView(i, null, listView);
                listItem.measure(0, 0);
                totalHeight += listItem.getMeasuredHeight();
            }

            ViewGroup.LayoutParams params = listView.getLayoutParams();
            params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
            listView.setLayoutParams(params);
        }
    }

It would definitely work! :)

Answer 2

If you want to create Listview with Header. Then Use Section Header Listview.

Refer this Example.

Hope it will help you!!

OR

If its fix that Only Two Listview & one Header Between them

Then

1) Take Only one Listview.

2) Use Custom Adapter & Custom Layout for Listview Row.

3) Add Two Extra TextView in Custom Layout

Listing First ListView Data

• (Fixed TextView - Header -Put its Visibility VISIBLE)
• (Extra 1 TextView - Header -Put its Visibility GONE )
• (Extra 2 TextView - Header -Put its Visibility GONE )

Listing Second ListView Data

• (Fixed TextView - Header -Put its Visibility GONE )
• (Extra 1 TextView - Header -Put its Visibility VISIBLE )
• (Extra 2 TextView - Header -Put its Visibility VISIBLE )
