Answer 1

You shouldn't put a ListView inside a ScrollView because ListView itself is a view group that displays a list of scrollable items. If you use it inside scrollview it will not receive scroll events because they all are handled by the parent ScrollView. Using a ListView to make it not scroll is extremely expensive and goes against the whole purpose of ListView. You should NOT do this. Just use a LinearLayout instead.

However, if you really want to do this you can have a look at this: How can I put a ListView into a ScrollView without it collapsing?

Use this code

public class MyListView  extends ListView {

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

    public MyListView  (Context context) {
        super(context);
    }

    public MyListView  (Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

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

In your parent layout set the height to wrap_content. This should work.
