谷歌眼镜 - “跳”到CardScrollView卡？ [英] Google Glass - 'Jump' to a card in CardScrollView?

问题描述

我有一个使用 CardScrollView 来显示一系列卡片的谷歌应用程序的玻璃。

I have a Google Glass app that uses a CardScrollView to display a series of Cards.

触摸手势工作卡之间移动，但我需要能够通过他们的指数跳转到特定的卡。我想用上下文语音命令（忽略其局限性现在）要做到这一点，例如：OK玻璃，去卡25

Touch gestures work to move between cards, but I need to be able to jump to specific cards by their index. I want to use contextual voice commands (ignore its limitations for now) to do this, for example: "ok glass, go to card 25".

我希望能够做这样的事......

I was hoping to be able to do something like this...

CardScrollView mCardScrollView = new CardScrollView(this);
    // ...
    // "ok glass, go to card 25"
    // ...
mCardScrollView.setFocus(25);

...但我似乎无法找到一个函数来做到这一点。

...But I can't seem to find a function to do that.

我没有找到谷歌的参考页面上的任何内容：<一href=\"https://developers.google.com/glass/develop/gdk/reference/com/google/android/glass/widget/CardScrollView\" rel=\"nofollow\">https://developers.google.com/glass/develop/gdk/reference/com/google/android/glass/widget/CardScrollView

I didn't find anything on Google's reference page: https://developers.google.com/glass/develop/gdk/reference/com/google/android/glass/widget/CardScrollView

和其样本code不包括此两种：结果
的https://developers.google.com/glass/develop/gdk/ui-widgets#scrolling_cards_in_activities

And their sample code doesn't cover this either:
https://developers.google.com/glass/develop/gdk/ui-widgets#scrolling_cards_in_activities

我想使用，以保持 CardScrollView 如果可能的话，因为我喜欢比它动画的方式，滚动 ViewFlipper 或 ViewPager 。它是这样一个简单的功能，我认为应该有。也许我失去了一些东西？

I'd like to keep using CardScrollView if possible because I like the way it animates and scrolls compared to ViewFlipper or ViewPager. It's such a simple functionality that I believe should be there. Perhaps I'm missing something?

推荐答案

我只是有一个类似的问题。我能够使用mCardScrollView.setSelection（cardPosition）和它的工作对M

I was just having a similar issue. I was able to use mCardScrollView.setSelection(cardPosition) and it worked for m
