如何在android中获取listview高度？

Question

我需要使用自定义ListVAdapter找到android ListView的高度.每个ListView项目的高度可以不同.我试过以下代码,我在这里找到了:

public static void setListViewHeightBasedOnChildren(ListView listView) {

        ListAdapter listAdapter = listView.getAdapter(); 
        if (listAdapter == null) {
            return;
        }

        int totalHeight = 0;
        for (int i = 0; i < listAdapter.getCount(); i++) {
            View listItem = listAdapter.getView(i, null, listView);
            listItem.measure(0, MeasureSpec.UNSPECIFIED);
            totalHeight += listItem.getMeasuredHeight();
        }

        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
        listView.requestLayout();
    } 

但它没有给出实际的高度; 它为所有列表项提供相同的高度.是否可以使用不同高度的列表项找到ListView高度？

private int getTotalHeightofListView() {

    ListAdapter LvAdapter = lv.getAdapter();
    int listviewElementsheight = 0;
    for (int i = 0; i < mAdapter.getCount(); i++) {
        View mView = mAdapter.getView(i, null, lv);
        mView.measure(
                MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
                MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
        listviewElementsheight += mView.getMeasuredHeight();
    }
    return listviewElementsheight;
}

试试这段代码.
