Metin görünümü ve araç çubuğu başlığı arasında paylaşılan geçiş geçişi

Question

Geri dönüştürücü görünümünde bir adı olan bir öğeyi ve öğenin adını gösteren bir daraltma araç çubuğuyla ayrıntılar etkinliğiyle ilgili bir öğem var. Öğenin adı ile araç çubuğu/daraltma araç çubuğunun başlığı arasında bir paylaşımlı geçiş geçişi eklemek istiyorum.

Selam ben KOTLIN içinde ilanıyla bir çözüm bulduk ama ancak parçası geçiş paylaşılanları hiç önemli değil inanıyoruz ama fikir biraz aynı

// from the start fragment init your end fragment whatever it is 
val endFragment = EndFragment.newInstance(/*...*/) 
val sharedView = view.findViewById<TextView>(R.id.mySharedTV) 
val sharedTransitionName = "myTransition" 

sharedView.transitionName = sharedTransitionName 

// define your transition 
val transition = TransitionInflater     
        .from(context) 
        .inflateTransition(android.R.transition.move) 
// define it as shared one 
endFragment.sharedElementEnterTransition = transition 

// pass the transition name to the endFragment 
val bundle = endFragment.arguments ?: Bundle() 
bundle.putString("sharedTransitionKey", sharedTransitionName) 
endFragment.arguments = bundle 

activity!!.supportFragmentManager 
      .beginTransaction() 
      .replace(R.id.myFragmentContainer, endFragment)   
      .addSharedElement(sharedView, sharedTransitionName) 
      .addToBackStack(null) // or add it 
      .commit() 

Açık

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

    val inflatedView = inflater.inflate(R.layout.myEndFragment, container, false) 
    /* here is the spot... */ 
    return inflatedView 
} 

diğer tarafı aşağıdaki seçenekler vardır:

<android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     android:minHeight="?attr/actionBarSize" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:titleTextColor="@android:color/white" 
     android:background="@color/colorPrimary"   
     app:title="My Title" /> 

yere

fun getToolbarTitleAsTextView(toolbar: Toolbar) : TextView? { 
    (0..toolbar.childCount).forEach { 
     val view = toolbar.getChildAt(it) 
     if (view is TextView) 
      return view 
    } 

    return null 
} 

bu tanımlanmış yöntemle

... ve kullanımı o

val toolbar = inflatedView.findViewById<Toolbar>(R.id.toolbar) 
val toolbarTitle = getToolbarTitleAsTextView(toolbar) 

veya

<android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     android:minHeight="?attr/actionBarSize" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:titleTextColor="@android:color/white" 
     android:background="@color/colorPrimary"> 

     <TextView 
      android:id="@+id/toolbarTitleTV" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title" 
      android:text="My Title"/> 
</android.support.v7.widget.Toolbar> 

... ve

val toolbarTitle = inflatedView.findViewById<Toolbar>(R.id.toolbarTitleTV) 

Eğer her iki durumda

// read the passed transitionName 
val bundle = endFragment.arguments ?: Bundle() 
val sharedTransitionName = bundle.getString("sharedTransitionKey") 
toolbarTitle.transitionName = sharedTransitionName 

yılında toolbarTitle var ... ve sihirli gerçekleştiğindenihayet
