Nested Listview in android ScrollView

Nested Listview in android ScrollView

If you follow the usual settings, the ListView in the ScrollView cannot display all of them, and it cannot slide. The Code searched from stackover flow can be used in the test!

1> set click monitoring events for listView:

 

ListView lv = (ListView) findViewById(R.id.layout_lv);lv.setOnTouchListener(new OnTouchListener() {    // Setting on Touch Listener for handling the touch inside ScrollView    @Override    public boolean onTouch(View v, MotionEvent event) {    // Disallow the touch request for parent scroll on touch of child view    v.getParent().requestDisallowInterceptTouchEvent(true);    return false;    }});

2> set a highly adaptive method for listView:

/**** Method for Setting the Height of the ListView dynamically. **** Hack to fix the issue of not showing all the items of the ListView **** when placed inside a ScrollView ****/ public static void setListViewHeightBasedOnChildren(ListView listView) { ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) return; int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), 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, LayoutParams.WRAP_CONTENT)); view.measure(desiredWidth, MeasureSpec.UNSPECIFIED); totalHeight += view.getMeasuredHeight(); } ViewGroup.LayoutParams params = listView.getLayoutParams(); params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)); listView.setLayoutParams(params); listView.requestLayout(); }

3> apply the settings to listView:

ListView list = (ListView) view.findViewById(R.id.ls); setListViewHeightBasedOnChildren(list);

OK ~~~
