Android 動態獲取ListView的高度

public static void setListViewHeightBasedOnChildren(ListView listView) 
{ 
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) 
{ 
// pre-condition 
return; 
} 
int totalHeight = 0; 
for (int i = 0; i < listAdapter.getCount(); i++)
{ 
View listItem = listAdapter.getView(i, null, listView); 
// listItem.measure(0, 0); 
listItem.measure( MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)); 
totalHeight += listItem.getMeasuredHeight(); 
}
ViewGroup.LayoutParams params = listView.getLayoutParams(); 
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)); 
listView.setLayoutParams(params); 
} 

　　

使用這個代碼來獲取listview的高度，須要注意一下幾個問題：
一、listview的item的根佈局必定要是LinearLayout；
二、調用這個方法須要在適配器數據加載更新以後；
代碼以下：
mAdapter.notifyDataSetChanged();
Function.getTotalHeightofListView(mListView);
三、獲取item的高度也能夠用註釋掉的代碼，效果同樣的
