【问题描述】：

我最近一直在使用你的 facebook 风格的 android 滑块，我想知道你是否可以帮助我。我需要使滑块从另一侧滑动。所以不是一开始从左向右滑动，我需要它从右向左滑动。

您能解释一下您是如何为我做到这一点的吗？

谢谢

问候， 菲利普

【问题讨论】：

添加有关您正在使用的库的信息会很有帮助。或者添加一些源代码。

【参考方案1】：

只需按照以下步骤，

1) 创建一个水平滚动视图。

2) 动态添加两个视图。

3) 使用 Layout Inflater 为两个视图充气。

4)然后将 child 1 设置为初始视图而不是 child 0 ，这样看起来就像从右向左移动而不是从左向右移动。

这里是关于类似 Facebook 的布局的对话。

你可以试试这个......

XML 是：

            <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
