Android: put two lists into a ScrollView

ugh nope :

I know that ListView objects shouldn't be put into a ScrollView. However, I can't come up with a proper approach to this situation: I have two layouts, both including a ListView, one directly below the other. I want all elements of both lists to be output; naturally, that should take more than the screen can offer, so I want to make the result scrollable, so, as I thought, I should put both into a ScrollView, but this doesn't work well with ListView (they only display one item each) and is considered a bad practice. How do I go about this?

Here's a mock up of what I mean:

Two lists, and the entirety of the second list can't fit into the screen, so I'd like to scroll it, and when I do, the second header ('Example2') scrolls up and doesn't stay in place, as opposed to the default behaviour of having the second list content scrolled.

What I have now is:

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="2"
        android:orientation="vertical">

        <RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">

            <TextView
                android:id="@+id/example1_header"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />

            <ListView
                android:id="@+id/example1_list_view"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_below="@id/example1_header" />

        </RelativeLayout>

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/example2_header />

            <ListView
                android:id="@+id/example2_list_view"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />

        </LinearLayout>

    </LinearLayout>

Rembulan Moon :

Maybe you can use NonscrollListView custom class that extends ListView.

public class NonScrollListView extends ListView {
    public NonScrollListView(Context context) {
        super(context);
    }
    public NonScrollListView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
                Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();
    }
}

After that you can use it, inside your Scrollview. For example (or you can put another Widget on Scrollview):

<ScrollView
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/textView">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <com.unicode.teslibrary.NonScrollListView
            android:id="@+id/bankList"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

        </com.unicode.teslibrary.NonScrollListView>

        <com.unicode.teslibrary.NonScrollListView
            android:id="@+id/bankSecondList"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

        </com.unicode.teslibrary.NonScrollListView>
    </LinearLayout>

</ScrollView>
