当我向上滚动时,它会折叠起来,并且NestedSrollView看起来像这样:

我希望它只滚动到这样的某个位置,之后用户不能再滚动:

我该如何实现? 这是我的主要XML:

将此行添加到NestedScrollView Child ...请参见下面的代码作为示例...

    android:nestedScrollingEnabled="true"

<android.support.v4.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fillViewport="true"
            app:layout_behavior="@string/appbar_scrolling_view_behavior">

                <android.support.v4.view.ViewPager
                    android:id="@+id/viewPager"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_below="@+id/tablayout"
                    android:layout_marginTop="2dp"
                    android:nestedScrollingEnabled="true"/> // add this line to NestedScrollView child
       </android.support.v4.widget.NestedScrollView>
