wie man Symbolleiste auf Scroll verstecken, wenn RecyclerView in NestedScrollView verwendet

Question

Ich benutze NestedScrollView, die zum Ausblenden der Symbolleiste auf Bildlauf, aber wenn ich setzen recyclerView drin, Symbolleiste nicht auf Scroll versteckt und ich evry mögliche Antwort in Stackoverflow aber nothings worsks und speziell ich benutzte recyclerView.setNestedScrollingEnabled(false);.

Hier ist mein Code:

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 



    android:layout_width="match_parent" 
    android:layout_height="match_parent" 

    app:layout_behavior="@string/appbar_scrolling_view_behavior"> 

<RelativeLayout 

    android:layout_width="match_parent" 
    android:background="#fff" 
    android:layout_height="wrap_content" 
    > 



    <android.support.v7.widget.RecyclerView 



     android:id="@+id/recyclerView" 
     android:background="#fafafa" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_centerInParent="true" /> 

    <ProgressBar 
     android:id="@+id/progressBar1" 

     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerInParent="true" /> 

</RelativeLayout> 

</android.support.v4.widget.NestedScrollView>

Answer 1

du versuchen können, diese attibute zu Ihrem AppBarLayout hinzufügen:

app:layout_scrollFlags="scroll|exitUntilCollapsed"

EDIT:

Ihren Code ändern, wie unten auch:

<?xml version="1.0" encoding="utf-8"?> 


<android.support.v4.widget.DrawerLayout 

    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:id="@+id/DrawerLayout" 

    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:elevation="7dp"> 
    <include 
     android:id="@+id/includeAppBar" 
     layout="@layout/app_bar_navigation_drawer" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 


    <android.support.v7.widget.RecyclerView 
     android:id="@+id/RecyclerView" 
     android:layout_width="320dp" 
     android:layout_height="match_parent" 
     android:layout_gravity="left" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior" // new attibute 
     android:background="#ffffff" 
     android:scrollbars="vertical"> 

    </android.support.v7.widget.RecyclerView> 
</android.support.v4.widget.DrawerLayout> 

this helps .

Entschuldigung für mein Englisch.
