scrollView中嵌套ListView，ListView不能滚动的问题

解决方案：

通过代码计算ListView实际使用的高度

 

/**

 * @return返回ListView的LayoutParams

 */

public staticViewGroup.LayoutParams getHeight(Adapter sa,ListView lv){

View itemView = sa.getView(0, null, lv);

itemView.measure(0,0);

inth= itemView.getMeasuredHeight();

inttotalHeight = sa.getCount() * h ;

ViewGroup.LayoutParamsparams = lv.getLayoutParams();

//总高度=总的item的高度+item之间的分割线高度

params.height = totalHeight+ (lv.getDividerHeight() * (sa.getCount()- 1));

returnparams;

 

}

 

listView.setAdapter(sa);

//在设置Adapter之后再设置ListView的显示

ViewGroup.LayoutParamsmaxheight = new calcListViewHeightHelper().getHeight(sa, listView);

listView.setLayoutParams(maxheight);
