listview嵌在scrollview里 只…

    
     public voidfixListViewHeight(ListView listView) {  

          // 如果没有设置数据适配器，则ListView没有子项，返回。  

          BaseAdapter listAdapter = (BaseAdapter) 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);
