android ScrollView嵌套Listview

android ScrollView嵌套Listview

如果按照平常的設定，ScrollView裡面的ListView是無法顯示全部的，而且還不能滑動，從stackover flow搜的代碼，親測可以用！

1>給listView設定點擊監視事件：

 

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>給listView設定高度自適應的方法：

/**** 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>讓listView應用該設定：

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

ok，搞定~~~
