Set image on Toolbar

This post show how to set image on Toolbar:

Modify from last post "Add OptionsMenu to Toolbar".

To set background image of Toolbar, edit layout/activity_main.xml to set android:background of <android.support.v7.widget.Toolbar>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    tools:context="com.blogspot.android_er.androidtoolbar.MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="56dp"
        android:background="@mipmap/ic_launcher"/>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!" />
</LinearLayout>

Another method, add ImageView inside <android.support.v7.widget.Toolbar>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    tools:context="com.blogspot.android_er.androidtoolbar.MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="56dp"
        android:background="#FFA000">
        <ImageView
            android:id="@+id/toolbarimage"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@mipmap/ic_launcher"/>
    </android.support.v7.widget.Toolbar>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!" />
</LinearLayout>

In this examples, also modify menu/menu_main.xml to set all app:showAsAction="ifRoom".

<?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/menu_camera"
        android:icon="@android:drawable/ic_menu_camera"
        android:orderInCategory="100"
        android:title="camera"
        app:showAsAction="ifRoom"/>
    <item
        android:id="@+id/menu_compass"
        android:icon="@android:drawable/ic_menu_compass"
        android:orderInCategory="100"
        android:title="compass"
        app:showAsAction="ifRoom"/>
    <item
        android:id="@+id/menu_agenda"
        android:icon="@android:drawable/ic_menu_agenda"
        android:orderInCategory="100"
        android:title="agenda"
        app:showAsAction="ifRoom"/>
    <item
        android:id="@+id/menu_gallery"
        android:icon="@android:drawable/ic_menu_gallery"
        android:orderInCategory="100"
        android:title="gallery"
        app:showAsAction="ifRoom"/>
    <item
        android:id="@+id/menu_calendar"
        android:icon="@android:drawable/ic_menu_my_calendar"
        android:orderInCategory="100"
        android:title="calendar"
        app:showAsAction="ifRoom"/>
</menu>
