如何在Android中将可拖动滚动条添加到scrollview/listview? [英] How to add draggable scrollbar to scrollview/listview in Android?

问题描述

我有一个使用我创建的customListAdapter的listView.当用户滚动列表时，他/她会像往常一样在右侧看到滚动指示器.

I have a listView that uses a customListAdapter created by me. When user scrolls the list, he/she sees scrolling indicator as usual on the right side.

但是，我想在右侧显示可拖动的跟踪按钮，以便用户可以按住该按钮并快速滚动列表.

However, I want to show a draggable track-button on the right side, so user will be able to hold that button and quickly scroll through the list.

我该怎么做?

推荐答案

我相信xml值fastScrollEnabled和可选的fastScrollAlwaysVisible是您要为ListView设置的值

I believe the xml values fastScrollEnabled and optionally fastScrollAlwaysVisible are what you want to set for the ListView

android:fastScrollEnabled="true"
android:fastScrollAlwaysVisible="true" 

fastScrollEnabled允许拖动滚动条.
