Kaydırma, yukarı kaydırırken neden daraltılmış araç çubuğunda durur? (Görüntüyü gösterecek kadar genişlemiyor)

Question

Başlıkta açıkladığım gibi, aşağı doğru çekildikten hemen sonra parmağımın yukarı kaydırılmasıyla aşağıdan yukarıya doğru kaydırırsam, kaydırma işlemi daraltılmış araç çubuğunda durur. Genişlemesini istiyorum. Nestedscrollview'i pürüzsüz bir şekilde çekersem sorun olmaz, araç çubuğu düzgün bir şekilde genişler. Nestedscrollview'de geri dönüştürücü görünümü var. İşte benim düzen önceden

Answer 1

AppBarLayout.Behavior'u başka bir stackoverflow answer, ile geçersiz kılan bir çok şey denedikten sonra, sorunu gideren bir kitaplık buldum. (smooth-app-bar-layout )

kullanımında 3 adım vardır. 3. adımda dikkatli olun. Koordinatorlayout'un altındaki smoothappbarlayout'un üzerine nestedscrollview koymalısınız.

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="match_parent"> 

    <android.support.v7.widget.NestedScrollView 
    android:id="@android:id/list" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" />

    <android.support.design.widget.CollapsingToolbarLayout 
     android:id="@+id/collapsing_toolbar_layout"

     app:layout_scrollFlags="scroll|exitUntilCollapsed">
