### **Toolbar**

* `Toolbar` makes it easy to set up an app bar that works on a wide range of devices.
* `Toolbar` gives you room to customize your app bar later, as your app develops.
* `Toolbar` includes the most recent features, and it works for any device that can use the support library.

```markup
<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    android:theme="?attr/actionBarTheme"
    app:layout_constraintEnd_toEndOf="parent"
    app:title="@string/app_name"
    app:titleTextColor="#fff"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />
```

```java
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
