如何在此特定代码中向操作栏添加小图标

Question

I've been searching for many questions, but there were not proper for myself.

I need one line to code to this:

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
</style>
<style name="MyActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:background">#547AF7</item>
</style>

PROBLEM: How to add little icon on the left

edit () I do not know why this doesnt work :

<item name="icon">@drawable/icon</item>

Answer 1

The use of application icon and title is discouraged in API Level 21, according to material design guidelines.

But if you want to set icon, you could use setLogo() method of Toolbar.

Answer 2

You might want to use:

<item name="android:background">@drawable/YOURIMAGENAMEHERE</item>

Or read this: https://developer.android.com/training/basics/actionbar/styling.html

Answer 3

You can add icon on ActionBar using android:icon="@drawable/your_icon.png"

<application> or <activity> tags in your app manifest.
