我正在尝试实现这一点
像我之前的其他人一样。
到目前为止,我发现了什么
我到目前为止:
父片段
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
initViewModel();
setupRecyclerView();
initViewModelSubscriptions();
}
@Override
public void onClick(View v, CustomNavigator.Extras extras) {
Bundle bundle = new Bundle();
bundle.putString("transitionName", v.getTransitionName());
NavController navController = NavHostFragment.findNavController(this);
navController.navigate(R.id.action_devicemgmt_to_deviceMgmtEditFragment,
bundle, // Bundle of args
null, // NavOptions
extras);
}
详细片段
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Transition t = TransitionInflater.from(getContext()).inflateTransition(R.transition.test).setDuration(1000);
setSharedElementEnterTransition(t);
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
setupToolbar();
setTransitionName();
}
private void setTransitionName() {
binding.coord.setTransitionName(getArguments().getString("transitionName"));
}
R.transition.test
<?xml version="1.0" encoding="utf-8"?>
<transitionSet xmlns:android="http://schemas.android.com/apk/res/android"
android:transitionOrdering="together"
android:interpolator="@android:interpolator/fast_out_slow_in">
<changeBounds/>
<changeTransform/>
<changeClipBounds/>
</transitionSet>
RecyclerView Adapter的ViewHolder
static class BindingHolder extends RecyclerView.ViewHolder {
private final ItemDevicemgmtBinding binding;
BindingHolder(ItemDevicemgmtBinding binding) {
super(binding.getRoot());
this.binding = binding;
binding.getRoot().setOnClickListener(v -> {
CustomNavigator.Extras extras = new CustomNavigator.Extras.Builder()
.addSharedElement(v, v.getTransitionName())
.build();
callback.onClick(v, extras);
});
}
void bind(String deviceSn) {
binding.getRoot().setTransitionName(String.valueOf(getItemId()));
binding.setVariable(BR.deviceSn, deviceSn);
binding.executePendingBindings();
}
}

如您所见,sharedEnterTransition正在工作,但是离开Fragment时的反向过渡不是我所期望的。代替片段容器,而是对项目容器进行转换。尼克·布彻(Nick Butcher)在我链接到第8点的视频中谈到了这种过渡,但是不幸的是,他只解释了滚动功能的崩溃。当我正确理解他时...
这个主意。以前的内容仍然存在。新的屏幕被提起并坐在上面
因此至少可以清楚地看到有两个单独的屏幕,而InboxRecyclerView
的创建者则以相同的布局进行操作。
但是在Nick的示例中,他使用的是Activity,而我使用的是Fragments,所以不确定在这里是否用Detail Fragment替换Parent Fragment是问题?!
那么有人可以帮助我吗?
