android - 如何在 ScrollView 中滚动 RecyclerView

Question

如何在scrollview中滚动所有RecyclerView上方

我必须在 ScrollView 中实现 RecyclerView，如下代码所示，但不能滚动 RecyclerView。

请回答

            <ScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_below="@+id/horizontalScrollView"
            android:layout_marginTop="10dp">

          <RelativeLayout...

                        <android.support.v7.widget.RecyclerView
                            android:id="@+id/rvpouch"
                            android:layout_width="match_parent"
                            android:layout_height="match_parent"
                            android:nestedScrollingEnabled="false"
                            android:layout_below="@+id/textView3">


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

                    </RelativeLayout>

        </ScrollView>

不要在 ScrollView 中使用 RecyclerView。使用 NestedScrollView 而不是 ScrollView。

NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.

例如:

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:descendantFocusability="blocksDescendants">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerView_one"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:nestedScrollingEnabled="false">

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

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerView_two"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:nestedScrollingEnabled="false">

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

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerView_three"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:nestedScrollingEnabled="false">

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

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

使用属性 android:nestedScrollingEnabled="false" 实现平滑滚动。
