I tried to make animations/transitions between activities but I couldn't make it perfect and good. And I couldn't find any helping guide. Can you tell me how to create an ActivityOptions tranistion, like this: http://3.bp.blogspot.com/-dadidlU3muU/VE6og4Ra_BI/AAAAAAAAA8E/uVCWrYMetGI/s400/herotransition.gif

一步一步？
谢谢你。

Step by step? Thanks.

推荐答案

您需要两个共享的元素：

You need two shared elements:

1. 卡时（全部的卡）从列表视图将被共享和
   映射到详细信息视图活动的根本看法。您可以
   过渡与一个ChangeBounds。


2. 从列表视图中的ImageView将被共享，并映射到详细视图活动ImageView的。您可以使用TransitionSet既ChangeBounds和ChangeImageTransform。

1. The card (the entire card) from the list view will be shared and mapped to the root view of the detail view activity. You can transition that with a ChangeBounds.
2. The ImageView from the list view will be shared and mapped to the ImageView in the detail view activity. You can use a TransitionSet with both ChangeBounds and ChangeImageTransform.

这意味着，您的活动的选项将是这个样子：

That means that your activity options will look something like this:

ActivityOptions.makeSceneTransition(YourActivity.this, Pair.create(yourCardViewInstance, "cardView"), Pair.create(yourImageViewInstance, "imageView")

最后，请确保您的第二个活动的意见都匹配在您ActivityOptions过渡名称。例如。

Finally, make sure that the views in your second activity have transition names that match those in your ActivityOptions. E.g.

<FrameLayout
    android:transitionName="cardView">
    <ImageView
      android:transitionName="ImageView">
...
