I can't scroll image with recyclerview.

You can use linearlayout's layout weight:
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/main_swipe"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<android.support.v7.widget.RecyclerView
android:id="#+id/rc"
android:layout_width="match_parent"
android:layout_height="match_parent"

/>
</android.support.v4.widget.SwipeRefreshLayout>
I have RecyclerView with the following layout for items:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:background="?android:attr/selectableItemBackground"
android:gravity="center">
<LinearLayout
android:id="#+id/name_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:transitionName="#string/transition_name_details">
<TextView
android:id="#+id/name"
style="#style/input_text_style"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:textColor="#color/primaryTextColor"/>
</LinearLayout>
When clicked on an item an activity is shown with the following layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:maxLines="1"
/>
</android.support.design.widget.TextInputLayout>
</LinearLayout>...
Unfortunately the value of the TextInputEditText is not showing when the second activity is displayed. But when I click on the TextInputEditText the value is then displayed.
Changing the first layout to this one solved the problem:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/name_layout"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:background="?android:attr/selectableItemBackground"
android:gravity="center"
android:transitionName="#string/transition_name_details">
<TextView
android:id="#+id/name"
style="#style/input_text_style"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:textColor="#color/primaryTextColor"/>
</RelativeLayout>

I just released my app using Material design patterns, am essentially using the out of box DrawerLayout/Nav and CardView/RecyclerView.
Here's the App if you want to try: https://play.google.com/store/apps/details?id=com.cp2.start.and.play.music.player , Works on all my devices but users report on Samsung S7 not so much
Here's the definitions:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
android:id="#+id/allotherelements"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".MainCardActivity"
tools:showIn="#layout/app_bar_main_card">
<android.support.v7.widget.RecyclerView
android:id="#+id/device_recycler_view"
