ListView 悬停 + 如何在每个Adapter获取没个View

转载 ：http://www.eoeandroid.com/thread-558736-2-1.html

ListAdapter listAdapter = listView.getAdapter();

if(listAdapter==null){

return;

}

int totalHeight = 0;

for(int i=0; len=listAdapter.getCount();i<len;i++){

   View listItem = listAdapter.getView(i,null,listView);  获取每个View

    listItem.measure(0,0);    // 计算子项View 的宽高   

    totalHeight += listItem.getMeasureHeight();  // 统计所有子项的总高度   

}

ViewGroup.LayoutParams parmas = listView.getLayoutParams();

parmas .height = totalHeight+(listView.getDividerHeight() * (listAdapter.getCound()-1));

listView.setLayoutParams(params);
