DataBinding点击事件没有反应

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"

    android:layout_width="0dp"

    android:layout_height="0dp"

    android:importantForAccessibility="no"

    android:onClick="@{()->handlers.showEditPhotoDialog()}"

    android:contentDescription="@string/content_description_edit_photo"

    android:scaleType="centerCrop"

    android:src="@drawable/tk_big_placeholder"

    app:couplePhoto="@{viewModel.couplePhotoUrl}"

    app:layout_constraintDimensionRatio="1:1"

    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

}
