问题所在:在ScrollView中嵌套使用ListView,ListView只会显示一行多一点 解决方案: 这里我贴出了核心代码 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 new Utility().setListViewHeightBasedOnChildren(lv); -------------------------------------------------------------------------------------------------- 上图: 原文地址:http://jackxlee.blog.51cto.com/2493058/666475 |
