它是可能的可变传递到从另一个片段一个previous片段？ [英] It is Possible to Pass a variable to a Previous Fragment from another Fragment?

问题描述

我试着去传递一个变量回到previous片段，类似startActivityForResult但碎片，这可能吗？

Im trying to pass a variable back to a previous Fragment, similar to startActivityForResult but with Fragments, Is this possible?

在code我使用要调用片段是这样的：

The code I am using To call a Fragment is this:

FragmentFullScreen fragment = new FragmentFullScreen();
        Bundle args = new Bundle();
        args.putParcelable(ARG_VIDEO_SELECTED, mVideoSelected);
        fragment.setArguments(args);

getFragmentManager().beginTransaction()
                .replace(R.id.container, FragmentFullScreen.newInstance(mVideoSelected))
                .addToBackStack("FragmentDetails")
                .commit();

然后我用popBackStack要到previous片段：

And then I using popBackStack to go to the previous Fragment:

getFragmentManager().popBackStack();

还有就是当我想更新从previous片段的变量。

And there is when I want to update a Variable from the Previous Fragment.

推荐答案

片段之间的通信应通过活动来完成。并实现片段和活动之间的沟通，这是最好的办法<一href=\"http://developer.android.com/guide/topics/fundamentals/fragments.html#CommunicatingWithActivity\" rel=\"nofollow\">http://developer.android.com/guide/topics/fundamentals/fragments.html#CommunicatingWithActivity.

Communication between fragments should be done via the activity. And to achieve this communication between fragment and activity, this is the best way http://developer.android.com/guide/topics/fundamentals/fragments.html#CommunicatingWithActivity.
