How can I place a ProgressBar at the right of the Toolbar?

Question

With the new Lollipop API, we have to use a Toolbar if we want to personalize the action bar aspect.

Adding a ProgressBar to the Toolbar is as simple as adding it to the Toolbar ViewGroup, as Chris Banes said.

<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/toolbar"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:background="@color/material_green_500"     android:minHeight="?attr/actionBarSize"     app:popupTheme="@style/ThemeOverlay.AppCompat.Light"     app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">      <!-- Color is Brown 500 -->     <ProgressBar         android:id="@+id/toolbar_progress_bar"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:indeterminateTint="#795548"         android:indeterminateTintMode="src_in"/>  </android.support.v7.widget.Toolbar> 

But how can we place it at the right of the Toolbar, where it belongs?

The layout_gravity attribute seems to not be defined for the Toolbar. Setting it from the xml has no effect. I tried to change the width of the ProgressBar, with no success.

What do I do?

EDIT: There is a programmatical solution to this problem, see @mdelolmo reply for that.

You can try this. It worked for me. Key here is to define layout_gravity in the xml: android:layout_gravity="right"

<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/toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/material_green_500" android:minHeight="?attr/actionBarSize" app:popupTheme="@style/ThemeOverlay.AppCompat.Light" app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">  <!-- Color is Brown 500 --> <ProgressBar     android:id="@+id/toolbar_progress_bar"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:indeterminateTint="#795548"     android:indeterminateTintMode="src_in"     android:layout_gravity="right" />  </android.support.v7.widget.Toolbar>
