android中Scrollview中套ListView,高度超出屏幕,listview无法滑动问题

比较忙,直接贴代码了。

先定义赋值:int desiredWidth = MeasureSpec.makeMeasureSpec(listview.getWidth(), MeasureSpec.AT_MOST);

然后调用方法

public void setListViewHeightBasedOnChildren(ListView listView,int desiredWidth) {
        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(desiredWidth, 0);
            totalHeight += listItem.getMeasuredHeight();
        }


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



此处使用时注意,如果你ListView的item的布局最外层是RelativeLayout,会报错,所以最外层要使用LinearLayout。
