Implementation backwards compatibility Roboto font in any control!.

Read the blog posts: RobotTextView RobotoTextFactory

Add library to your project or clone it and do the following:

• Add all fonts into Asses/fonts and ensure they are marked as AndroidAsset as the build action
• Add RobotoTextView and feel free to change the namespace
• Add the custom attributes in the attrs.xml in your Resources/Values folder.

In any layout that you wish to use the Roboto Font simply include a new xmlns

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

Then create a new RobotoTextView

<com.refractored.controls.RobotoTextView
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          local:typeface="roboto_thin"
          android:text="Roboto Thin"
          android:textAppearance="?android:attr/textAppearanceMedium" />

The most important part is: local:typeface

Valid options are:

• roboto_thin
• roboto_thin_italic
• roboto_light
• roboto_light_italic
• roboto_regular
• roboto_medium
• roboto_medium_italic
• roboto_bold
• roboto_bold_italic
• roboto_black
• roboto_black_italic
• roboto_condensed
• roboto_condensed_italic
• roboto_condensed_bold
• roboto_condensed_bold_italic

You can apply this same concept to any other control such as a CheckedTextView.

Also included is RobotoTextFactory. If you want you will still need the typeface enum attribute but this will allow you to add the typeface to any View that derives from TextView such as Button, CheckBox, etc. All you will need to do is set the RobotoTextFactory before SetContentView is called:

protected override void OnCreate(Bundle bundle)
{
    base.OnCreate(bundle);
    LayoutInflater.Factory = new RobotoTextFactory();
    // Set our view from the "main" layout resource
    this.SetContentView(Resource.Layout.Main);
}

In your axml file all you need to do is add the custom attribute onto any of your Views:

<CheckBox
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:text="CheckBox with Roboto Thin"
     local:typeface="roboto_thin" />

This will result in something like this:
