我有具有報頭的圖像和ViewPager配方片段，以及我現在面臨兩個問題與當前設計：如何使ViewPager滾動並將標題圖像製作爲摺疊工具欄？
1-除非我按下標題圖片和啓動上的選項卡內容不垂直滾動滾動。我的意思是，如果我在頁眉圖像上垂直滑動，視圖將滾動。但如果我嘗試從文本區域垂直滑動，它不會滾動。 （我有一個圖像如下）
2-標題圖像並不是所有的方式來取代工具欄像當前版本谷歌Play商店顯示的應用程序，如下面的第一個截圖，第二個截圖是我的應用程序好像。
這裏是我的我的fragment_recipe.xml：
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/main_content"

android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="@+id/tab_app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
