  • Android之ScrollView嵌套ListView

    ScrollView中嵌套使用ListView,ListView只会显示的内容只有一行多一点

    解决方案:

    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);
               }
        }

    setAdapter方法之后调用

    new Utility().setListViewHeightBasedOnChildren(lv);
