Add the repository and dependency to your project

Add this line to the root layout in your xml

xmlns:ioniconview="http://schemas.android.com/apk/res-auto"

now you can use iconviews and populate view the with any of these icons

<be.webelite.ion.IconView
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  
  ioniconview:name="ion_ionic" <!-- this sets the icon -->
  android:textSize="40dp" <!-- this sets the icon size -->
  android:textColor="#ff0000" <!-- this sets the icon color -->
  />

for a list of available icons please check out ionicons.com ion-loading becomes ion_loading ion-ionic becomes ion_ionic

All credits go out to ionicons.com

Ready to use android library including rotating icons!

To use, add the following to your project's build.gradle file:

repositories {
    maven { url 'https://github.com/MarsVard/IonIconView/raw/master/maven' }
}

dependencies {
    compile 'be.webelite:ion-iconview:1.0.+@aar'
}

thanks to @Sonelli for explaining how maven works :)
