ScrollView里面动态设置listView的Item个数

private void setListViewHeight(ListView listView, CoachAdapter adapter, int count) {
int totalHeight = 0;
for (int i = 0; i < count; i++) {
View listItem = adapter.getView(i, null, listView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * count);
listView.setLayoutParams(params);
}

setListViewHeight(lvCoach, coachAdapter, 2);
lvCoach.setAdapter(coachAdapter);
