提问by Anita
I have a ListView with an edit text and a button below it. When I click on a listView item the keyboard appears and push up the edit text and the button. I want the list to scroll to the selected item. Any idea? Thanks

You can use ListView's setSelection(int position)method to scroll to a row.
您可以使用 ListView 的setSelection(int position)方法滚动到一行。

For a direct scroll:
对于直接滚动：
getListView().setSelection(11);
For a smooth scroll:
对于平滑滚动：
getListView().smoothScrollToPosition(11);
To Scroll to top
滚动到顶部
getListView().setSelectionAfterHeaderView();
Note
笔记
try to call it in post because sometime listview is not yet created while you calling it's method
尝试在 post 中调用它，因为有时在调用它的方法时还没有创建 listview
getListView().postDelayed(new Runnable() {
@Override
public void run() {
lst.setSelection(15);
}
},100L);

Setup a listener on your the list item being clicked, then use View.getTop()or View.getBottom()when clicked to get it's position within the parent. You can then use ListView.scrollTo(x, y)to scroll to the list item.
在被单击的列表项上设置一个侦听器，然后使用View.getTop()或View.getBottom()在单击时获取它在父项中的位置。然后您可以使用ListView.scrollTo(x, y)滚动到列表项。

您可以使用
smoothScrollToPosition(position)
Just increase the position of item with 1, and you will get the view of item.
只需将 item 的位置增加 1，您将获得 item 的视图。
getListView().smoothScrollToPosition(position + 1);

Using duration gives a better user experience. Use this, with duration added. Will scroll the item in position smoothly to the top of the listview.
使用持续时间可以提供更好的用户体验。使用它，并添加持续时间。将位置中的项目平滑地滚动到列表视图的顶部。
int duration = 500; //miliseconds
int offset = 0; //fromListTop
listview.smoothScrollToPositionFromTop(position,offset,duration);
- descrease duration to make scrolling faster
- 减少持续时间以加快滚动速度
