Question

Is it possible to align the menu icons of a toolbar in the center? I used another way shown here,but there I was putting images inside my Toolbar layout. Now I want to try it with menu icons:).

here is my code.

bottm 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"
xmlns:appo="http://schemas.android.com/apk/res-auto"
android:minHeight="50dp"
android:background="@color/colorPrimary"
appo:theme="@style/ToolbarTheme"
appo:popupTheme="@style/Theme.AppCompat.Light">

menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
    android:id="@+id/news"
    app:showAsAction="always"
    android:orderInCategory="100"
    android:icon="@drawable/new_icon"
    android:title="News">

</item>

<item
    app:showAsAction="always"
    android:id="@+id/camera"
    android:icon="@drawable/camera_icon"
    android:orderInCategory="100"
    android:title="Camera"
   ></item>
<item
    app:showAsAction="always"
    android:id="@+id/facebook"
    android:icon="@drawable/facebooc_image"

ToolBar is just a ViewGroup. You can add Images into to it just like into a RelativeLayout or LinearLayout. for example,

<android.support.v7.widget.Toolbar
    android:id="@+id/toolBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:layout_scrollFlags="scroll|enterAlways">

    <TextView
        android:id="@+id/toolbar_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:ellipsize="end"
        android:singleLine="true"
        android:textAllCaps="true"
        android:textColor="@color/white_color"
        android:textSize="@dimen/textSize12" />

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