Keine Freigabe Moment in ScrollView

Question

In meiner Tätigkeit habe ich zwei RecyclerView s in einem ScrollView. Das Problem ist, dass, wenn ich das ScrollView swipe/flick, das Scrollen sofort stoppt. Gibt es eine Möglichkeit, den ScrollView Impuls oder Trägheit zu implementieren, so gibt es etwas Verzögerung, bevor das Scrollen aufhört?

Meine XML ist unter:

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 

<ProgressBar 
    android:id="@+id/threadload_progress" 
    style="?android:attr/progressBarStyleLarge" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_marginBottom="8dp" 
    android:visibility="gone" /> 
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:orientation="vertical"> 

    <android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:id="@+id/subforums" 
     android:name="net.polunom.forum.fragments.ThreadFragment" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:layoutManager="LinearLayoutManager" 
     tools:context=".fragments.ThreadFragment" 
     tools:listitem="@layout/fragment_subforum"/> 

    <android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:id="@+id/threadlist" 
     android:name="net.polunom.forum.fragments.ThreadFragment" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:layoutManager="LinearLayoutManager" 
     tools:context=".fragments.ThreadFragment" 
     tools:listitem="@layout/fragment_thread"/> 

</LinearLayout> 
</ScrollView> 

Answer 1

ich es herausgefunden! Alles, was ich tun musste, war setNestedScrollingEnabled(false); zu den beiden RecyclerView s, und alles begann wie ein Charme zu arbeiten.

Answer 2

Sie können deaktivieren verschachtelt mit direkt in die XML-Scrolling: android:nestedScrollingEnabled="false"

So Ihre XML würde wie folgt aussehen:

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 

<ProgressBar 
    android:id="@+id/threadload_progress" 
    style="?android:attr/progressBarStyleLarge" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_marginBottom="8dp" 
    android:visibility="gone" /> 
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:orientation="vertical"> 

    <android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:id="@+id/subforums" 
     android:nestedScrollingEnabled="false" 
     android:name="net.polunom.forum.fragments.ThreadFragment" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:layoutManager="LinearLayoutManager" 
     tools:context=".fragments.ThreadFragment" 
     tools:listitem="@layout/fragment_subforum"/> 

    <android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:id="@+id/threadlist" 
     android:nestedScrollingEnabled="false" 
     android:name="net.polunom.forum.fragments.ThreadFragment" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:layoutManager="LinearLayoutManager" 
     tools:context=".fragments.ThreadFragment" 
     tools:listitem="@layout/fragment_thread"/> 

</LinearLayout> 
</ScrollView>
