我想要进行与this one相同的转换,它来自材料设计。
我遵循了一些教程,展示了如何做到这一点,但绝大多数使用Activitys,因为我必须使用片段。最后我得到了一个粗略的结果,但它仍然不是我想要的。我得到的结果是this one。
如您所见,转换忽略了CardView,只有图像出现在我们面前。以下是我目前的代码。
MainFragment
public class MainFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
final View v = inflater.inflate(R.layout.fragment_market, container, false);
return v;
}
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
final ImageView propertyImage = view.findViewById(R.id.propertyImageView);
propertyImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
sharedTransition(propertyImage);
}
});
}
public void sharedTransition(ImageView imageView) {
SharedMainFragment simpleFragmentB = new SharedMainFragment();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
TransitionSet transitionSet = new TransitionSet();
transitionSet.setOrdering(TransitionSet.ORDERING_TOGETHER);
transitionSet.addTransition(new ChangeBounds())
.addTransition(new ChangeTransform())
.addTransition(new ChangeImageTransform());
simpleFragmentB.setSharedElementEnterTransition(transitionSet);
simpleFragmentB.setSharedElementReturnTransition(transitionSet);
}
getActivity().getSupportFragmentManager()
.beginTransaction()
.addSharedElement(imageView, ViewCompat.getTransitionName(imageView))
.addToBackStack("SHARED")
.replace(R.id.fragment_container, simpleFragmentB)
.commit();
}
}

可能为时已晚,但是我相信如果您希望cardView包含在过渡动画中, 您需要具备:
