Android How can I set an item in the toolbar to fill all the free space?

I tried to assign the scales, of course, but it doesn't seem to be supported by the toolbar.

You can use the following to get rid of the left margin in the toolbar

app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"

So your code could be like this:

<android.support.v7.widget.Toolbar
        app:contentInsetLeft="0dp"
        app:contentInsetStart="0dp"
        android:layout_width="match_parent"
        android:layout_height="48dp">

        <TextView
            android:id="@+id/progress"
            android:layout_width="match_parent"
            android:layout_height="48dp"
            android:background="@color/background_floating_material_dark" />
    </android.support.v7.widget.Toolbar>

Edit You can do in code as well -

toolbar.setContentInsetsAbsolute(0,0);

Even you can change it in style -

<item name="toolbarStyle">@style/Widget.Toolbar</item>

<style name="Widget.Toolbar" parent="@style/Widget.AppCompat.Toolbar">
<item name="contentInsetStart">0dp</item>
</style>
