public static void setListViewHeightBasedOnChildren(ListView listView) {
    if(listView == null) return;
    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(0, 0);
        totalHeight += listItem.getMeasuredHeight();
    }
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
}

 

如果是要设置listView的item间距，可以在xml而已文件中的listView下设置xml属性：

android:divider="#00000000"   //分隔线为透明色

android:dividerHeight="20dp"   //高度为20dp
