My layout does not render

Question

I was watching and copying a code from the first class of Material Design of the Thiengo Calopsita youtube, It turns out that the file xml of activity_main and of toolbar_bottom is not rendering in Android Studio, according to the error, there is some problem in the class android.support.v7.widget.Toolbar!

How to render layout?

follows the code activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/tb_main"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:minHeight="?attr/actionBarSize"
        android:background="?attr/colorPrimary" />

    <TextView
        android:layout_below="@+id/tb_main"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:text="@string/hello_world"
        android:textColor="@color/black"/>

    <include
        android:id="@+id/inc_tb_bottom"
        layout="@layout/toolbar_Bottom"/>

</RelativeLayout>

Follows the code of toolbar_bottom.xml

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/tb_bottom"
    android:layout_alignParentBottom="true"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:theme="@style/Theme.MyThemeBottom">

    <ImageView
        android:id="@+id/iv_settings"
        android:src="@drawable/settings"
        android:layout_width="24dp"
        android:layout_height="24dp"
        />

</android.support.v7.widget.Toolbar>

Answer 1

1. Try switching <android.support.v7.widget.Toolbar for < Toolbar
2. And trade app:theme="@style/Theme.MyThemeBottom"> for android:theme="@style/Theme.MyThemeBottom">

Made that of a Clean Build.

Answer 2

Next: In the Preview Window at the top there is a line with several icons, the last icon is the android doll with the title : "Android Version to use when Rendering layouts..." switch from 22 to 21 that resolves
