I'm trying to add AppCompat toolbar in my application but I am unable to display it in correct way. I followed steps from this tutorial: <http://www.android4devs.com/2014/12/how-to-make-material-design-app.html> but the toolbar overlaps ListView and parts of it are separated. I don't know how to describe it well, so here is the screen of my app:

Below I am attaching codes of toolbar and my view. Could you please help to fix the toolbar?

Toolbar:

```
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/toolbar_primary"
>

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

```

Activity view:

```
<?xml version="1.0" encoding="utf-8"?>
<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="10dp"
android:paddingRight="10dp"
android:paddingTop="10dp"
android:paddingBottom="10dp"
tools:context="bak.grzegorz.pl.smm.Activities.MessageList">

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

<ListView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@android:id/list"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    />

</RelativeLayout>

```
