将Bundle传递给startActivityForResult以实现场景过渡 [英] Pass a Bundle to startActivityForResult to achieve Scene Transitions

问题描述

我在玩棒棒糖sceneTransitionAnimations.

要使其正常工作，您需要在调用活动的onCreate中实现getWindow().setExitTransition() + getWindow().setReenterTransition()， 以及被叫活动的onCreate中的getWindow().setEnterTransition() + getWindow().setReenterTransition().

To get it to work you need to implement getWindow().setExitTransition() + getWindow().setReenterTransition() in the calling activity's onCreate, and getWindow().setEnterTransition() + getWindow().setReenterTransition() in the called activity's onCreate.

然后，当您调用startActivity时，必须将Bundle传递给通过调用ActivityOptions.makeSceneTransitionAnimation(getActivity()).toBundle()获得的函数.

Then, when you call startActivity you have to pass a Bundle to that function that you obtain by calling ActivityOptions.makeSceneTransitionAnimation(getActivity()).toBundle().

这很好.但是，我需要使用startActivityForResult开始一项活动.此函数仅使用Intent和requestCode，而无需使用Bundle.使用putExtras将捆绑包放入意图中无效.

This works fine. However I need to start an activity using startActivityForResult. This function only takes an Intent and a requestCode, but no Bundle. Putting the bundle into the intent using putExtras did not work.

当我想使用startActivityForResult时，如何使这些漂亮的棒棒糖过渡效果正常工作?

How do I get these nice Lollipop transitions to work when I want to use startActivityForResult?

按要求输入代码进行

我在一个片段中，我有一个物品清单.单击某个项目后，我将开始另一个活动.

I am inside a Fragment, I have a list of items. When an item is clicked I start another activity.

Intent intent = new Intent(context, otherActivity.class);
Bunde bundle = null; 
if (android.os.Build.VERSION.SDK_INT >= 21)
    bundle = ActivityOptions.makeSceneTransitionAnimation(getActivity()).toBundle();

现在有两个区别.这一项有效:

now here come the two distinctions. This one works:

getActivity().startActivity(intent, bundle);

该片段不提供此功能，因此我必须使用其父级活动-因此是getActivity().

The Fragment does not offer this function, so I have to use its parent activity's - hence the getActivity().

此操作不起作用:

intent.putExtras(bundle);
startActivity(intent);

推荐答案

感谢Squonk，我意识到我要使用的方法startActivityForResult(Intent intent, int requestCode, Bundle options)实际上存在.

Thanks to Squonk I have come to realize that the method I am trying to use, startActivityForResult(Intent intent, int requestCode, Bundle options) actually exists.

我犯了一个错误，即尝试从未实现的Fragment(与startActivity(Intent intent, Bundle bundle)相同)开始，因此您需要调用getActivity().startActivityForResult(Intent intent, int requestCode, Bundle options).

I had done the mistake of trying to start that from a Fragment, where it is not implemented - same as startActivity(Intent intent, Bundle bundle) - so you need to call getActivity().startActivityForResult(Intent intent, int requestCode, Bundle options) .
