The online monitoring of the rewriting ScrollView slides is used to hide and display a certain control. The sliding of this method is not very smooth, so I decided to use the latest Material Design to achieve this effect. Not much nonsense, directly apply the code:

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:background="@color/white">
        <!-Part 1: CoordinatorLayout->
        <android.support.design.widget.CoordinatorLayout
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:id="@+id/scrollview"
            android:layout_width="fill_parent"
            android:layout_height="match_parent"
            android:background="#ffffff">
            <!-Second part: Actsa control->
            <android.support.design.widget.AppBarLayout
                android:id="@+id/id_appbarlayout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">
                <android.support.design.widget.CollapsingToolbarLayout
                    android:id="@+id/collapsing_tool_bar_test_ctl"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:fitsSystemWindows="true"
                    app:contentScrim="?attr/colorPrimary"
                    app:expandedTitleMarginEnd="64dp"
                    app:expandedTitleMarginStart="48dp"
                    app:layout_scrollFlags="scroll">
                    <LinearLayout
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:orientation="vertical">
                        <com.bigkoo.convenientbanner.ConvenientBanner
                            android:id="@+id/convenient_banner"
                            android:layout_width="match_parent"
                            android:layout_height="400px"
                            app:canLoop="true" />
                        <maibai.maibai.com.maibai.util.view.MyGridView
                            android:id="@+id/grid_view"
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content"
                            android:numColumns="4"
                            android:layout_marginTop="20px"
                            android:verticalSpacing="20px"
                            android:listSelector="@color/white"/>
                        <TextView
                            android:layout_width="match_parent"
                            android:layout_height="1px"
                            android:background="#eee"
                            android:layout_marginTop="20px"/>
                        <LinearLayout
                            android:layout_width="match_parent"
                            android:layout_height="400px"
                            android:background="#eee"></LinearLayout>
                    </LinearLayout>

                <LinearLayout

                    android:layout_height="50px"
                    android:background="#ff66bb"
                    android:orientation="horizontal">
                    <TextView
                        android:layout_width="match_parent"
                        android:layout_height="match_parent" 
                        android:text="Suspension part"/>
                </LinearLayout>
            </android.support.design.widget.AppBarLayout>
            <!-3 part: Your Scroll View->
            <android.support.v4.widget.NestedScrollView
                android:id="@+id/myMainScrollView"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:overScrollMode="always"
                app:layout_behavior="@string/appbar_scrolling_view_behavior">
                <maibai.maibai.com.maibai.util.view.MyListView
                    android:id="@+id/list_view"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:listSelector="@color/white"
                    android:divider="@color/white"/>
            </android.support.v4.widget.NestedScrollView>
        </android.support.design.widget.CoordinatorLayout>
    </LinearLayout>

Here is the layout file. The outermost layer is CoordinatorLayout, and then the control of the control when sliding should be hidden in the collapsingToolBarlayout. In the NestedScrollView, there is a sliding control that can be slide after the top, and then the effect can be achieved, which is so simple.
Need to pay attention to a few points:
1.CollapsingToolBarlayout must set the app: layout_scrollflags = “scroll” to slide.
2.NESTEDScrollView must set the attribute of the App: layout_Behavior, and they will link.
3. IncrollView innestedScrollView should rewrite the onMEASUSUSURES method of ListView (a lot of online) when nesting such as listView.
