Error inflating class <unknown> Android

Good day. Tell me, what reasons can cause the Error inflating class? For example, 2 markup. In the first, everything works out, when the second one is loaded, the application falls.

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <com.widget.lavkaviews.text.Text android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="3 товара на сумму" android:id="@+id/description" android:textColor="@color/black" /> <com.widget.lavkaviews.text.Text android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/summ" android:layout_alignParentRight="true" android:textColor="@color/black" android:layout_toLeftOf="@+id/ruble" android:layout_alignBottom="@+id/description" /> <com.widget.lavkaviews.PriceText android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/finish" android:text="ОФОРМИТЬ" android:layout_below="@+id/description" android:gravity="center" android:textColor="@color/main" android:background="@color/lavka_main_red" /> </RelativeLayout> 

The second

 <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="8dp" xmlns:android="http://schemas.android.com/apk/res/android"> <!--android:background="@color/main"--> <ImageView android:layout_width="50dp" android:layout_height="50dp" android:id="@+id/image" /> <com.widget.lavkaviews.text.Text android:layout_width="match_parent" android:layout_height="wrap_content" android:text="" android:id="@+id/title" android:textColor="@color/black" android:maxLines="2" android:layout_toRightOf="@+id/image" /> <com.widget.lavkaviews.PriceText android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/price"/> <!--<com.widget.lavkaviews.PriceText--> <!--android:layout_width="80dp"--> <!--android:layout_height="20dp"--> <!--android:id="@+id/price"--> <!--android:textColor="#262626"--> <!--android:layout_alignParentRight="true" />--> <com.widget.lavkaviews.Dropdown android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/portion" android:layout_toLeftOf="@+id/incrementor" /> <!--android:layout_below="@+id/price"--> <com.widget.lavkaviews.Incrementor android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/incrementor" android:layout_alignParentRight="true" android:layout_alignTop="@+id/portion" /> <com.widget.core.view.ProductNDIndicator android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/nd"/> </RelativeLayout> 

A class that is not recognized is PriceText. The error appears on both the physical device and the emulator, in the same place, on the second markup. Judging by the spectra - in the place of the announcement. There are no differences in my opinion.
