Question

我有CoordinatorLayout：

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbars"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/background"
    android:orientation="vertical"
    app:elevation="0dp">

    <TextView
        android:id="@+id/title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="@dimen/_8sdp"
        android:layout_marginLeft="@dimen/_2sdp"
        android:layout_marginTop="@dimen/_4sdp"
        android:paddingLeft="@dimen/_4sdp"
        android:paddingRight="@dimen/_4sdp"
        android:text="Rating AND Reviews for Burris 4-16x50mm Eliminator III Ballistic Laserscope Riflescope "
        android:textColor="@color/black"
        android:textSize="@dimen/_16sdp"
        app:layout_scrollFlags="scroll|enterAlwaysCollapsed"/>


    <com.app.views.recycleview.RecycleView
        android:id="@+id/reviews_star_filter_recycler"

        android:background="@drawable/solid_white_border_gray_no_padding"

    <LinearLayout

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="@dimen/_4sdp"
        android:background="@drawable/solid_white_border_gray_no_padding"
        android:orientation="vertical">

            android:gravity="center_vertical"
            android:inputType="none"
            android:paddingLeft="@dimen/_10sdp"
            android:text="test \nMost Helpful"
            android:textColor="@color/middle_gray"
            android:textSize="12sp"
            />


        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center_vertical"
            android:orientation="horizontal"
            app:layout_scrollFlags="scroll|enterAlwaysCollapsed">

            <View
                android:layout_width="match_parent"
                android:layout_height="2px"
                android:layout_margin="10dp"
                android:layout_weight="1.1"
                android:background="@color/divider_color_light"/>

            <TextView
                android:id="@+id/count"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Showing 1-40 of 1,465"
                android:textColor="@color/middle_gray"/>

            <TextView
                android:id="@+id/reset"
                android:layout_width="wrap_content"

            <View
                android:layout_width="match_parent"
                android:layout_height="2px"
                android:layout_margin="10dp"
                android:layout_weight="1"
                android:background="@color/divider_color_light"/>

        </LinearLayout>
    </LinearLayout>
</android.support.design.widget.AppBarLayout>

<com.app.opticsplanet.views.recycleview.VerticalRecycleView
   android:id="@+id/reviews_recycler_view"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:background="@drawable/solid_white_border_gray_no_padding"
   android:overScrollMode="never"
   app:layout_behavior="@string/appbar_scrolling_view_behavior" />

</android.support.design.widget.CoordinatorLayout>

InfinityListener添加了VerticalRecycleView。 VerticalRecycleView有无尽的滚动。它的作品非常完美。

但如果有＆lt;列表中的10个项目，无限侦听器被禁用，在这种情况下，我想显示BottomView。

但是将VerticalRecycleView重新加工到此容器后会出现问题：

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

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

            <com.app.opticsplanet.views.recycleview.VerticalRecycleView
                android:id="@+id/reviews_recycler_view"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:overScrollMode="never"
                android:background="@drawable/solid_white_border_gray_no_padding"
                />

            <com.app.opticsplanet.views.BottomView
                android:id="@+id/bottom_view"
                android:layout_marginTop="@dimen/_8sdp"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:visibility="gone"/>
        </LinearLayout>
    </android.support.v4.widget.NestedScrollView>

此监听器无效：

mReviewsRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);
                if (dy > 0) //check for scroll down
                {
                    visibleItemCount = recyclerView.getChildCount();
                    totalItemCount = mLayoutManager.getItemCount();
                    firstVisibleItem = mLayoutManager.findFirstVisibleItemPosition();

                    if (loading) {
                        if (totalItemCount > previousTotal) {
                            loading = false;
                            previousTotal = totalItemCount;
                        }
                    }
                    if (!loading && (totalItemCount - visibleItemCount)
                            <= (firstVisibleItem + visibleThreshold)) {
                        loading = true;
                        currentPage++;
                        loadNewPage(currentPage);
                    }
                }
            }
        });

如何解决？如果列表中有<10个项目，可能还有其他解决方案如何显示BottomView

Try using relative layout with parent bottom

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

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            >

            <com.app.opticsplanet.views.recycleview.VerticalRecycleView
                android:id="@+id/reviews_recycler_view"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:overScrollMode="never"
                android:layout_above="@+id/bottom_view"
                android:background="@drawable/solid_white_border_gray_no_padding"
                />

            <com.app.opticsplanet.views.BottomView
                android:id="@+id/bottom_view"
                android:layout_marginTop="@dimen/_8sdp"
                android:layout_width="match_parent"
                android:layout_alignParentBottom="true"
                android:layout_height="match_parent"
                android:visibility="gone"/>
        </RelativeLayout>
    </android.support.v4.widget.NestedScrollView>

CoordinatorLayout中的多个项目具有无限滚动
