如何解决只有 android.R.transition.move 不工作
我试图向我的片段添加共享元素过渡，但 move 过渡不起作用
val transition = TransitionInflater.from(context).inflateTransition(android.R.transition.move)
如果我将 android.R.transition.move 更改为 android.R.transition.explode 或 android.R.transition.slide_left 动画将起作用，但不是需要的动画
我使用导航库
第一个片段代码：
class TimersListFragment : Fragment() {
private lateinit var binding: FragmentTimersListBinding
private lateinit var viewModel: TimerListViewModel
private lateinit var setListAdapter: SetListAdapter
override fun onCreateView(
inflater: LayoutInflater,container: ViewGroup?,savedInstanceState: Bundle?
): View {
binding = FragmentTimersListBinding.inflate(inflater)
viewModel = ViewModelProvider(this).get(TimerListViewModel::class.java)
return binding.root
}
override fun onViewCreated(view: View,savedInstanceState: Bundle?) {
super.onViewCreated(view,savedInstanceState)
super.onStart()
setListAdapter = SetListAdapter()
setListAdapter.onItemClicked = { set,name,time ->
val extras = FragmentNavigatorExtras(name to "setName",time to "setTime")
val action = TimersListFragmentDirections.previewSet(set.setInfo.setId)
findNavController().navigate(action,extras)
}
binding.listSets.layoutManager = LinearLayoutManager(context)
binding.listSets.adapter = setListAdapter
}
}
