Toolbar image centered

Using the last android.support.v7.widget.Toolbar I want to center an image in the toolbar but it keeps staying on the left.

The best way for me would be to use toolbar.setLogo() method and to center the logo but i don't see any way to do it.

I use a layout for the Toolbar:

  <android.support.v7.widget.Toolbar style="@style/ToolBarStyle"
                                   xmlns:android="http://schemas.android.com/apk/res/android"
                                   android:layout_width="match_parent"
                                   android:layout_height="wrap_content"
                                   android:background="?attr/colorPrimary"
                                   android:minHeight="@dimen/abc_action_bar_default_height_material">

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

Is there any possibility to add an image (logo) to the toolbar and center it? programatically or in the layout?

Toolbar is just a ViewGroup, you can customize is as much as you want.

Try this :

<android.support.v7.widget.Toolbar
   style="@style/ToolBarStyle"
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:background="?attr/colorPrimary"
   android:minHeight="@dimen/abc_action_bar_default_height_material">

    <ImageView
        android:layout_width="wrap_content"
        android:contentDescription="@string/logo"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:src="@drawable/ic_launcher"/>

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

This should bring your imageView in center of toolbar.

If you have any views and can't quite get the logo centered, it will be because the centering is based on remaining space, not the entire toolbar.

To guarantee the logo being centered, try using a layer-list as a background of your toolbar instead of trying to use an image as a view.

toolbar.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/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="@drawable/toolbar_background"
    android:theme="@style/ThemeOverlay.AppCompat.Dark"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    app:layout_scrollFlags="scroll|enterAlways"
    app:layout_collapseMode="pin">
</android.support.v7.widget.Toolbar>

toolbar_background.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item>
    <shape android:shape="rectangle">
      <solid android:color="@color/colorPrimary" />
    </shape>
  </item>
  <item>
    <bitmap android:src="@drawable/logo" android:gravity="center" />
  </item>
</layer-list>

That should ensure a centered logo, with a specific background colour.

This is not the best solution but it's a work around that works even when you have up button or menu item.

try

<FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

    <android.support.v7.widget.Toolbar
       style="@style/ToolBarStyle"
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:background="?attr/colorPrimary"
       android:minHeight="@dimen/abc_action_bar_default_height_material"/>

    <ImageView
        android:layout_width="wrap_content"
        android:contentDescription="@string/logo"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:src="@drawable/ic_launcher"/>

</FrameLayout>
