滑动以添加叠加视图？

Question

我想添加一个顶部覆盖视图，并向下滑动，并添加一个底部覆盖视图，并向上滑动。使用FragmentActivity。

如何显示叠加视图？

您可以使用Android中的展示库使用手形图标滑动

ShowcaseView sv;
ViewTarget target = new ViewTarget(R.id.yourviewid, this);
sv = ShowcaseView.insertShowcaseView(target, this, R.string.showcase_main_title, R.string.showcase_main_message, co);

从上到下滑动

sv.animateGesture(0, 0, 0, -400);

和从下到上滑动

sv.animateGesture(0, 0, 0, 400);
