Set Toolbar logo in XML

Question

Is it possible to set Toolbar logo in xml? I have tried this so far:

1.

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    ...
    android:logo="@drawable/my_logo"
    />

2.

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    ...
    app:logo="@drawable/my_logo"
    />

---

EDIT

I'm using toolbar as an actionbar in my AppCompatActivity:

setSupportActionBar(findViewById(R.id.toolbar));

I'm able to set logo from code:

((Toolbar) findViewById(R.id.toolbar)).setLogo(R.drawable.my_logo);

But I'd like to set logo either from layout XML or from Style/Theme XML.

Answer 1

Do Change

app:logo="@drawable/my_logo"

to

app:navigationIcon="@drawable/my_logo"

UPDATE

Add Linearlayout into your toolbar xml tag.

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/grey">

    <LinearLayout
        android:layout_width="match_parent"
        android:orientation="horizontal"
        android:layout_height="wrap_content">

        <ImageView
            android:id="@+id/media_image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:adjustViewBounds="true"
            android:contentDescription="new post image"
            android:scaleType="centerCrop"
            android:visibility="visible" />
        <TextView
            android:id="@+id/toolbar_subtitle"
            android:textSize="14sp"
            android:layout_gravity="center"
            android:textColor="@color/black"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </LinearLayout>


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

Answer 2

Using xml only

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

<style name="ActionbarLogo">
    <item name="android:logo">@drawable/ic_menu_camera</item>
    <item name="android:displayOptions">useLogo</item>
</style>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="android:actionBarStyle">@style/ActionbarLogo</item>
    <item name="windowNoTitle">true</item>
</style>

Now apply AppTheme.NoActionBar theme to your activity( and if you want to remove toolbar title use getSupportActionBar().setDisplayShowTitleEnabled(false); after setSupportActionBar(toolbar);)

<activity
  android:name=".MainActivity"
  android:theme="@style/AppTheme.NoActionBar">
  <intent-filter>
      <action android:name="android.intent.action.MAIN"/>

      <category android:name="android.intent.category.LAUNCHER"/>
  </intent-filter>
</activity>

Answer 3

Actually you can, but it will not work well with name on Toolbar. You can just put ImageView into the body of Toolbar, like you do this with Layout.

<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

   <ImageView
   android:layout_height="wrap_content"
   android:layout_width="wrap_content"
   app:logo="@drawable/my_logo"/>

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

Better if you will do this from the code:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.my_logo);

Answer 4

To display logo icon set this icon at runtime in ActionBar.

getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(@drawable/my_logo);
