How can I put a ListView into a ScrollView without it collapsing?

Question

I\'ve searched around for solutions to this problem, and the only answer I can find seems to be \"don\'t put a ListView into a ScrollView\". I have yet to see any real expl

Answer 1

There are two issue when using a ListView inside a ScrollView.

1- ListView must fully expand to its children height. this ListView resolve this:

public class ListViewExpanded extends ListView
{
    public ListViewExpanded(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        setDividerHeight(0);
    }

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST));
    }
}

Divider height must be 0, use padding in rows instead.

2- The ListView consumes touch events so ScrollView can't be scrolled as usual. This ScrollView resolve this issue:

public class ScrollViewInterceptor extends ScrollView
{
    float startY;

    public ScrollViewInterceptor(Context context, AttributeSet attrs)
    {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent e)
    {
        onTouchEvent(e);
        if (e.getAction() == MotionEvent.ACTION_DOWN) startY = e.getY();
        return (e.getAction() == MotionEvent.ACTION_MOVE) && (Math.abs(startY - e.getY()) > 50);
    }
}

This is the best way I found to do the trick!
