android中scrollview与listview嵌套共存
public class Utility { public void setListViewHeightBasedOnChildren(ListView listView) { //获取ListView对应的Adapter ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) { return; } int totalHeight = 0; for (int i = 0, len = listAdapter.getCount(); i < len; i++) { //listAdapter.getCount()返回数据项的数目 View listItem = listAdapter.getView(i, null, listView); listItem.measure(0, 0); //计算子项View 的宽高 totalHeight += listItem.getMeasuredHeight(); //统计所有子项的总高度 } ViewGroup.LayoutParams params = listView.getLayoutParams(); params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)); //listView.getDividerHeight()获取子项间分隔符占用的高度 //params.height最后得到整个ListView完整显示需要的高度 listView.setLayoutParams(params); }}
?在setAdapter方法之后调用
Utility().setListViewHeightBasedOnChildren(lv);
