原先項(xiàng)目中有相關(guān)解決代碼，但仔細(xì)測(cè)試發(fā)現(xiàn)當(dāng)item高度不固定時(shí)，無(wú)法計(jì)算出正確的ListView所需高度，它是按UI中的固定高度去計(jì)算的，搜索后解決這一問(wèn)題，記錄下：

    /**
     * 解決scrollview嵌套listview，且item高度不固定時(shí)，無(wú)法計(jì)算正確高度的bug
     *
     * @param listView
     */
    public void setListViewHeightBasedOnChildren(ListView listView) {

        // 獲取ListView對(duì)應(yīng)的Adapter
        ListAdapter listAdapter = listView.getAdapter();
        if(listAdapter == null) {
            return;
        }
        int totalHeight = 0;

        for(int i = 0; i < listAdapter.getCount(); i++) { // listAdapter.getCount()返回?cái)?shù)據(jù)項(xiàng)的數(shù)目

            View listItem = listAdapter.getView(i, null, listView);
            //寬度為屏幕寬度
            int i1 = View.MeasureSpec.makeMeasureSpec(ScreenUtil.getScreenWidth(),View.MeasureSpec.EXACTLY);
            //根據(jù)屏幕寬度計(jì)算高度
            int i2 = View.MeasureSpec.makeMeasureSpec(i1, View.MeasureSpec.UNSPECIFIED);
            listItem.measure(i1, i2);
            totalHeight += listItem.getMeasuredHeight(); // 統(tǒng)計(jì)所有子項(xiàng)的總高度
        }
        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));

        // listView.getDividerHeight()獲取子項(xiàng)間分隔符占用的高度
        // params.height最后得到整個(gè)ListView完整顯示需要的高度
        listView.setLayoutParams(params);

    }
