CardRecyclerView not showing

[AdityaKamra]

Hi Gabriel,

I am trying to make a material card list but nothing is visible. Here is my code: <<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:card="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent">

<LinearLayout
    android:id="@+id/carddemo_progressContainer"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:visibility="gone"
    android:gravity="center">

    <ProgressBar
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:text="This is the test Text"
        android:textColor="#000000"
        android:paddingTop="4dip"
        android:singleLine="true"/>

</LinearLayout>

<FrameLayout
    android:id="@+id/carddemo_listContainer"

    android:layout_width="match_parent"
    android:paddingLeft="2dp"
    android:paddingRight="2dp"
    android:layout_height="match_parent">

    <it.gmariotti.cardslib.library.recyclerview.view.CardRecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:elevation="10dp"
        card:list_card_layout_resourceID="@layout/material_card_for_list"
        android:id="@+id/carddemo_recyclerview"/>

    <TextView

        android:id="@android:id/empty"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:textColor="#000000"
        android:textAppearance="?android:textAppearanceMedium"
        android:text="No data..."/>
