Listview inside ViewPager with SlidingTabLayout - height issues

Question

I have a fragment in which I placed the ViewPager with TabLayout, the contents of the ViewPager is the fragment containing the ListView.

I know that my ViewPager cannot use wrap_content, the height at the beginning is not calculated.

So, I did this:

 @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        boolean wrapHeight = MeasureSpec.getMode(heightMeasureSpec) == MeasureSpec.AT_MOST;

        final View tab = getChildAt(0);
        if (tab == null) {
            return;
        }

        int width = getMeasuredWidth();
        if (wrapHeight) {
            // Keep the current measured width.
            widthMeasureSpec = MeasureSpec.makeMeasureSpec(width, MeasureSpec.EXACTLY);
        }
        Fragment fragment = ((Fragment) getAdapter().instantiateItem(this, getCurrentItem()));
        heightMeasureSpec = getMeasureExactly(fragment.getView(), widthMeasureSpec);

        //Log.i(Constants.TAG, "item :" + getCurrentItem() + "|height" + heightMeasureSpec);
        // super has to be called again so the new specs are treated as
        // exact measurements.
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

    int getMeasureExactly(View child, int widthMeasureSpec) {
        child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
        int height = calculateHeight ((ListView)child.findViewById(R.id.list)); //getMeasuredHeight();

        System.out.println("Height is: "+height);
        return MeasureSpec.makeMeasureSpec(height , MeasureSpec.EXACTLY);
    }


    private int calculateHeight(ListView list) {

        int height = 0;

        for (int i = 0; i <10; i++) {
            View childView = list.getAdapter().getView(i, null, list);
            childView.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
            height+= childView.getMeasuredHeight();
        }

        //dividers height
      //  height += list.getDividerHeight() * 11; //list.getCount();

        return height;

    }

I get a list with 10 lines to populate, but only 9 are visible, one of them goes out of view.

The question is how can I accurately measure the height of the list line and add it up to 10 elements.

This question haunts stackoverflow, but there seems to be no concrete solution. In particular, for a child of a ListView. How can I make it work with TableLayout.

I also know how recordings and scrolling do it, but it’s by design, and I can’t do it.
