1. ?在布局文件中:?

<data>

? ? ? ? name="presenter"

? ? ? ? type="com.xogrp.planner.user.contract.UserProfileContract.Presenter" />

</data>

<androidx.appcompat.widget.AppCompatImageView

? ? android:id="@+id/iv_cover_photo"

? ? app:layout_constraintEnd_toEndOf="parent"

? ? app:layout_constraintStart_toStartOf="parent"

? ? app:layout_constraintTop_toTopOf="parent" />

2. 在Fragment 文件中:

override fun onPlannerCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View {

? ?Timber.tag(LIFECYCLE_TAG).d("UserProfileFragment.onPlannerCreateView $savedInstanceState")

? ?mViewModel = UserProfileViewModel(user)

? ? mDataBinding = DataBindingUtil.inflate(inflater, getLayoutRes(), container, false)

? ? mDataBinding.viewModel =mViewModel

? ? mDataBinding.presenter =mPresenter

? ? mDataBinding.handlers = Handlers()

? ? if (savedInstanceState !=null) {

? ? ? ? ?mViewModel.memberPayload =savedInstanceState.getSerializable(KEY_PAYLOAD)as MemberPayload?

? ? ? ? ? ? ??: MemberPayload()

? ? }

? ? ?return mDataBinding.root

}
