ScrollView嵌套ListView或者GridView显示不全是因为滑动冲突，计算ListView或者GridView的高度就行了

/** * 根据数据设置ListView，GridView的高度,从而确定其在ScrollView的显示高度 * * */public class ListViewUtility {    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, 0);            totalHeight += listItem.getMeasuredHeight();        }        ViewGroup.LayoutParams params = listView.getLayoutParams();        int height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount()));        params.height = height;        listView.setLayoutParams(params);    }    public void setGridViewHeight(GridView gridview, int num) {        ListAdapter Adapter = gridview.getAdapter();        if (Adapter == null) {            return;        }        int size = Adapter.getCount();        int row = size / num;        if (size % num != 0) {            row += 1;        }        gridview.measure(0, 0);        View gridItem = Adapter.getView(0, null, gridview);        gridItem.measure(0, 0);        int height = gridItem.getMeasuredHeight();        ViewGroup.LayoutParams params = gridview.getLayoutParams();        params.height = row * height;        gridview.setLayoutParams(params);    }    public int getGridViewHeight(GridView gridview, int num) {        ListAdapter Adapter = gridview.getAdapter();        if (Adapter == null) {            return 0;        }        int size = Adapter.getCount();        int row = size / num;        if (size % num != 0) {            row += 1;        }        gridview.measure(0, 0);        View gridItem = Adapter.getView(0, null, gridview);        gridItem.measure(0, 0);        int height = gridItem.getMeasuredHeight();        return row * height;    }}
