如何使查看recyclerview永久示例不滚动嵌套scrollview

Question

嗨，我想使视图不能滚动recyclerview，例如以上textlay回滚视图nestedscrollview，如何使textview不滚动，而回收滚动像往常一样

我的代码

<?xml version="1.0" encoding="utf-8"?> 
<android.support.v4.widget.NestedScrollView 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:keepScreenOn="true" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    android:fillViewport="true" > 

    <RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:gravity="center_horizontal" 
     android:focusableInTouchMode="true" 
     android:paddingBottom="@dimen/activity_vertical_margin" 
     android:paddingLeft="@dimen/activity_horizontal_margin" 
     android:paddingRight="@dimen/activity_horizontal_margin" 
     android:paddingTop="@dimen/activity_vertical_margin" > 

     <TextView 
      android:id="@+id/textView" 
      android:textColor="#43a047" 
      android:typeface="serif" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:layout_alignParentTop="true" 
      android:text="@string/app" 
      android:gravity="center" 
      android:textStyle="bold" 
      android:textSize="15sp" /> 

     <android.support.v7.widget.RecyclerView 
      xmlns:android="http://schemas.android.com/apk/res/android" 
      android:id="@+id/recyclerview" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:layout_below="@+id/textView" 
      android:layout_marginTop="5dp" 
      android:divider="@color/colorAccent" 
      android:dividerHeight="1dp" /> 

</RelativeLayout> 

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

如何让TextView中不会滚动

Answer 1

你有NestedScrollView内TextView。因此，您的TextView因该父视图而滚动。类似的东西会工作：

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

    <TextView 
     android:id="@+id/textView" 
     android:textColor="#43a047" 
     android:typeface="serif" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignParentTop="true" 
     android:text="@string/app" 
     android:gravity="center" 
     android:textStyle="bold" 
     android:textSize="15sp" /> 

    <android.support.v7.widget.RecyclerView 
     android:id="@+id/recyclerview" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_below="@+id/textView" 
     android:layout_marginTop="5dp" 
     android:divider="@color/colorAccent" 
     android:dividerHeight="1dp" /> 
</RelativeLayout> 

Answer 2

的RecyclerView自身滚动的，所以只是删除NestedScrollView

<RelativeLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:gravity="center_horizontal" 
    android:focusableInTouchMode="true" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" > 

    <TextView 
     android:id="@+id/textView" 
     android:textColor="#43a047" 
     android:typeface="serif" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignParentTop="true" 
     android:text="@string/app" 
     android:gravity="center" 
     android:textStyle="bold" 
     android:textSize="15sp" /> 

    <android.support.v7.widget.RecyclerView 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/recyclerview" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_below="@+id/textView" 
     android:layout_marginTop="5dp" 
     android:divider="@color/colorAccent" 
     android:dividerHeight="1dp" />
