如何创建Android中的半透明灰教程覆盖？ [英] How do I create the semi-transparent grey tutorial overlay in Android?
问题描述
当你首次运行Android设备（你看到了很多，如果你使用的仿真器）有是关于如何使用发射器和添加小工具，等等。我想一个有用的小教程你知道吗发现这对谷歌的例子，但我不能。我希望你明白我的意思。这是一个与在每一步蓝色的好按钮。
You know when you run an Android device for the first time (something you see a lot if you use the emulator) that there's a helpful little tutorial about how to use the launcher and add widgets, etc. I'm trying to find an example of this on Google, but I can't. I'm hoping you know what I mean. It's the one with the blue "okay" buttons at each step.
不管怎样，我想创建一个是我的应用程序，但我不知道这是去这样做的最佳方式。
Anyway, I want to create one for my app, but I'm not sure which is the best way to go about doing it.
我创建一个片段，我可以对我的经常性活动前半透明并将它显示只在第一次运行？
Do I create a Fragment that I can make semi-transparent on top of my regular activity and have it show up on only the first run?
让我的半透明巴纽本教程的每一部分，它覆盖了在第一次运行的常规发射活动呢？
Do I make a semi-transparent .png for each section of the tutorial and overlay it over the regular launcher activity on the first run?
如果我选择后者，我怎么可以调整所有不同的屏幕尺寸？我可以只呈现在Photoshop中图像各个方面，但不会涵盖所有的人。如果我去的片段路线，我只能说match_parent，而不是担心。但我必须弄清楚如何片段工作，他们混淆了地狱了我。
If I do the latter, how can I adjust for all the various screen sizes? I could just render the image in Photoshop to various dimensions, but that won't cover all of them. If I go the fragment route, I can just say "match_parent" and not worry about it. But then I have to figure out how Fragments work, and they confuse the hell out of me.
