在我的应用程序中,当用户点击联系人图标时,我想在幻灯片中显示联系人信息,该信息从底部显示,可以向上扫描以覆盖整个屏幕,或者向下滑动到消失。
我尝试使用umano的SlidingUpPanel,但我无法让它按照我的需要工作,因为它不是为此而设计的。
那里有一些图书馆吗?

这在Android中称为BottomSheet。您可以使用视图作为协调器布局的子项创建自己的底部工作表。
添加到您的应用build.gradle:
dependencies{
compile 'com.android.support:design:24.1.1'
}
然后使用这些类创建自己的类:

这是一个过于简化的演示,演示如何使FrameLayout充当底部工作表,您可以使用Fragment替换FrameLayout的内容,并根据需要将信息传递给它。 (在您的情况下,无论点击哪个联系人):
