Android list view inside a scroll view

Question

I have an android layout which has a scrollView with a number of elements with in it. At the bottom of the scrollView I have a listView

Answer 1

found a solution for scrollview -> viewpager -> FragmentPagerAdapter -> fragment -> dynamic listview, but im not the author. there is some bugs, but at least it works

public class CustomPager extends ViewPager {

    private View mCurrentView;

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

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

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        if (mCurrentView == null) {
            super.onMeasure(widthMeasureSpec, heightMeasureSpec);
            return;
        }
        int height = 0;
        mCurrentView.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
        int h = mCurrentView.getMeasuredHeight();
        if (h > height) height = h;
        heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

    public void measureCurrentView(View currentView) {
        mCurrentView = currentView;
        this.post(new Runnable() {
            @Override
            public void run() {
                requestLayout();
            }
        });
    }

    public int measureFragment(View view) {
        if (view == null)
            return 0;

        view.measure(0, 0);
        return view.getMeasuredHeight();
    }
}


public class MyPagerAdapter extends FragmentPagerAdapter {

    private List fragments;
    private int mCurrentPosition = -1;


    public MyPagerAdapter(FragmentManager fm) {
        super(fm);//or u can set them separately, but dont forget to call notifyDataSetChanged()
        this.fragments = new ArrayList();
        fragments.add(new FirstFragment());
        fragments.add(new SecondFragment());
        fragments.add(new ThirdFragment());
        fragments.add(new FourthFragment());
    }

    @Override
    public void setPrimaryItem(ViewGroup container, int position, Object object) {
        super.setPrimaryItem(container, position, object);
        if (position != mCurrentPosition) {
            Fragment fragment = (Fragment) object;
            CustomPager pager = (CustomPager) container;
            if (fragment != null && fragment.getView() != null) {
                mCurrentPosition = position;
                pager.measureCurrentView(fragment.getView());
            }
        }
    }

    @Override
    public Fragment getItem(int position) {
        return fragments.get(position);
    }

    @Override
    public int getCount() {
        return fragments.size();
    }
}

fragments layout can be anything

then somewhere just

lv = (ListView) view.findViewById(R.id.lv1);
        lv.setAdapter(arrayAdapter);
        setListViewHeightBasedOnChildren(lv);
    }

    public static void setListViewHeightBasedOnChildren(ListView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        if (listAdapter == null)
            return;

        int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(),
                View.MeasureSpec.UNSPECIFIED);
        int totalHeight = 0;
        View view = null;
        for (int i = 0; i < listAdapter.getCount(); i++) {
            view = listAdapter.getView(i, view, listView);
            if (i == 0)
                view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth,
                        LinearLayout.LayoutParams.WRAP_CONTENT));

            view.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
            totalHeight += view.getMeasuredHeight();
        }
        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight
                + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
        listView.requestLayout();
    }
