CoordinatorLayout与RecyclerView Scroll bug

Question

这就是我想要的东西

请帮我解决我的问题。

1. 我有这个观点，但首先滚动RecyclerView无法正常工作。另外，我想补充一点，我首先TextView点击RecyclerView。我做错了什么？或者帮我构建一个布局。
2. 也许有人知道为什么我们向<?xml version="1.0" encoding="utf-8"?> <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/white" tools:context="com.bottlemessage.btlmsg.view.module.game.wallet.WalletActivity"> <ImageView android:id="@+id/wallet_activity_back_btn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginStart="8dp" android:layout_marginTop="12dp" android:padding="4dp" android:src="@drawable/selector_background_back_btn" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" /> <com.bottlemessage.btlmsg.view.util.view.TextTypeface android:id="@+id/wallet_activity_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginStart="24dp" android:text="@string/wallet_activity_title" android:textColor="@color/blue" android:textSize="20sp" app:layout_constraintBottom_toBottomOf="@+id/wallet_activity_back_btn" app:layout_constraintStart_toEndOf="@+id/wallet_activity_back_btn" app:layout_constraintTop_toTopOf="@+id/wallet_activity_back_btn" app:typeface="textbook_bold" tools:text="Discounts" /> <FrameLayout android:id="@+id/wallet_activity_separator" android:layout_width="match_parent" android:layout_height="1dp" android:layout_marginEnd="3dp" android:layout_marginStart="3dp" android:layout_marginTop="10dp" android:background="#E9EBF0" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/wallet_activity_title" /> <FrameLayout android:id="@+id/wallet_activity_main_container" android:layout_width="0dp" android:layout_height="0dp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/wallet_activity_separator"> <android.support.design.widget.CoordinatorLayout android:id="@+id/main_content" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.design.widget.AppBarLayout android:id="@+id/appbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" app:elevation="0dp"> <include android:id="@+id/toolbar" layout="@layout/wallet_activity_toolbar" /> <FrameLayout android:id="@+id/wallet_activity_separator2" android:layout_width="match_parent" android:layout_height="1dp" android:layout_marginEnd="3dp" android:layout_marginStart="3dp" android:background="#E9EBF0" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/wallet_activity_title" /> </android.support.design.widget.AppBarLayout> <com.chauthai.overscroll.RecyclerViewBouncy android:id="@+id/wallet_activity_recycler" android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior" /> <FrameLayout android:id="@+id/wallet_activity_item_copy_container" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginBottom="12dp" android:layout_marginEnd="8dp" android:layout_marginStart="8dp" android:layout_marginTop="12dp" android:background="@drawable/background_rectangle_item_expand_in_wallet" android:clickable="true" android:focusable="true" android:visibility="gone" app:layout_constraintTop_toBottomOf="@+id/toolbar" /> <LinearLayout android:id="@+id/wallet_activity_item_empty_list_block" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:orientation="vertical" android:visibility="visible" app:layout_constraintTop_toBottomOf="@+id/toolbar"> <ImageView android:layout_width="80dp" android:layout_height="80dp" android:layout_gravity="center" android:src="@drawable/ic_empty_discount_list" /> <com.bottlemessage.btlmsg.view.util.view.TextTypeface android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="30dp" android:text="@string/discount_activity_no_discounts_yet" android:textAlignment="center" android:textSize="24sp" /> </LinearLayout> </android.support.design.widget.CoordinatorLayout> </FrameLayout> <FrameLayout android:id="@+id/wallet_activity_whoops_block" android:layout_width="match_parent" android:layout_height="match_parent" android:clickable="true" android:focusable="true" android:visibility="gone" /> </android.support.constraint.ConstraintLayout> 添加项目而RecyclerView的高度为0.项目仅在点击空白区域时显示

这是布局
