/**
* 设置Listview的高度
*/
public void setListViewHeight(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if(listAdapter ==null) {
return;
}
inttotalHeight =0;
for(inti =0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(ia,null, listView);
listItem.measure(0,0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParamsparams = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() -1));
listView.setLayoutParams(params);
}
这个方法设置的item的Layout必须是带有onMeasure()方法的控件，否则在计算的时候会报错，建议使用LinearLayout。
第二种（自定义ListView）
@OverridepublicvoidonMeasure(intwidthMeasureSpec,intheightMeasureSpec){intexpandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >>2,
MeasureSpec.AT_MOST);super.onMeasure(widthMeasureSpec, expandSpec);
}
