android: How can I implement first time tutorial like Go Launcher in my app?
提问by moallemi
Go Launcher have a nice first-time tutorial. it is very similar to Stock ICS first time run. I want to learn how to make the similar tutorial display at the first launch of my app. How can I implement this Transparent view (which interacts with screen objects) in my android app?
Go Launcher 有一个很好的初次使用教程。它与 Stock ICS 第一次运行非常相似。我想学习如何在我的应用程序第一次启动时显示类似的教程。如何在我的 android 应用程序中实现这个透明视图（它与屏幕对象交互）？

I was trying to do something similarusing a transparent activity with a viewpager inside it. I wanted static 'tutorial' images that users could swipe through.
我试图使用一个透明的活动来做类似的事情，里面有一个viewpager。我想要用户可以滑动的静态“教程”图像。
One of the answers to my question mentioned an interesting library (called ShowcaseView). It seems like it may be a good fit for your requirements as well.
我的问题的一个答案提到了一个有趣的库（称为 ShowcaseView）。它似乎也很适合您的要求。

You can either use a FrameLayout or RelativeLayout as root of your Activity/Fragment, and put your "first time" View upon content with a (almost) transparent background, or use another Activity/Fragment themed with a transluscent window. (like this)
您可以使用 FrameLayout 或 RelativeLayout 作为 Activity/Fragment 的根，并将“第一次”视图放在具有（几乎）透明背景的内容上，或者使用另一个以半透明窗口为主题的 Activity/Fragment。（像这样）
I'd rather use an Activity/Fragment, but this is up to you!
我宁愿使用活动/片段，但这取决于您！

I wrote little library That contains a simple component for making ??a app tour. It`s very restricted to my case but maybe could be your case . Single LessonCardView Showed onstartactivity for the first time or on button click Any criticism ,help or advice will be appreciated. thanks https://github.com/dnocode/DnoLib
我写了一个小库，它包含一个用于制作应用程序的简单组件。它非常限于我的情况，但也许可能是你的情况。单个 LessonCardView 首次在开始活动或按钮单击时显示任何批评、帮助或建议，我们将不胜感激。感谢https://github.com/dnocode/DnoLib
