wemall app商城源码中ScrollView中嵌套ListView主要代码

private void fixListViewHeight(ListView listView) {// TODO Auto-generated method stub // 如果没有设置数据适配器，则ListView没有子项，返回。 ListAdapter listAdapter = listView.getAdapter(); int totalHeight = 0; if (listAdapter == null) { return; } for (int i = 0, len = listAdapter.getCount(); i < len; i++) { View listViewItem = listAdapter.getView(i , null, listView); // 计算子项View 的宽高 listViewItem.measure(0, 0); // 计算所有子项的高度和 totalHeight += listViewItem.getMeasuredHeight(); } ViewGroup.LayoutParams params = listView.getLayoutParams(); // listView.getDividerHeight()获取子项间分隔符的高度 // params.height设置ListView完全显示需要的高度 params.height = totalHeight+ (listView.getDividerHeight() * (listAdapter.getCount() - 1)); listView.setLayoutParams(params);}
