Usage

In XML

To set up a typeface you must specify the parameter robotoTypeface:

<com.devspark.robototextview.widget.RobotoTextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:robotoTypeface="roboto_light_italic"/>

or specify a set of parameters robotoFontFamily, robotoTextWeight and robotoTextStyle:

<com.devspark.robototextview.widget.RobotoTextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:robotoFontFamily="roboto"
    app:robotoTextWeight="light"
    app:robotoTextStyle="italic"/>

Set up typeface in code:

In Code

Using parameter typeface:

RobotoTextView textView = new RobotoTextView(context);
RobotoTypefaces.setUpTypeface(
        textView, 
        RobotoTypefaces.TYPEFACE_ROBOTO_LIGHT_ITALIC);

Using parameters fontFamily, textWeight and textStyle:

RobotoTextView textView = new RobotoTextView(context);
RobotoTypefaces.setUpTypeface(
        textView, 
        RobotoTypefaces.FONT_FAMILY_ROBOTO,
        RobotoTypefaces.TEXT_WEIGHT_LIGHT,
        RobotoTypefaces.TEXT_STYLE_ITALIC);

With Span

Using parameter typeface:

RobotoTypefaceSpan span = new RobotoTypefaceSpan(
        context, 
        RobotoTypefaces.TYPEFACE_ROBOTO_LIGHT_ITALIC);
Spannable spannable = new SpannableString("text");
spannable.setSpan(span, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Using parameters fontFamily, textWeight and textStyle:

RobotoTypefaceSpan span = new RobotoTypefaceSpan(
        context,
        RobotoTypefaces.FONT_FAMILY_ROBOTO,
        RobotoTypefaces.TEXT_WEIGHT_LIGHT,
        RobotoTypefaces.TEXT_STYLE_ITALIC);
Spannable spannable = new SpannableString("text");
spannable.setSpan(span, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Roboto Inflater

To apply roboto typeface for original TextView (like a Calligraphy) you must attach inflater in your Activity class in the #onCreate() method.

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    RobotoInflater.attach(this);
    super.onCreate(savedInstanceState);
}

and specify the typeface in xml:

<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:robotoTypeface="roboto_light_italic"
    tools:ignore="MissingPrefix"/>

Note: Popular IDE's (Android Studio, IntelliJ) will likely mark this as an error despite being correct. You may want to add tools:ignore="MissingPrefix" to either the View itself or its parent ViewGroup to avoid this. You'll need to add the tools namespace to have access to this "ignore" attribute. xmlns:tools=" http://schemas.android.com/tools". See https://code.google.com/p/android/issues/detail?id=65176.

Gradle

If you intend to use is not all fonts, the extra fonts can be removed.

android.applicationVariants.all{ variant ->
    variant.mergeAssets.doLast {
        File fonts = file("$variant.mergeAssets.outputDir/fonts")
        if (fonts.exists()) {
            for (File file : fonts.listFiles()) {
                if (file.getName().contains("RobotoSlab")) {
                    println("delete " + file.getName() + " font")
                    file.delete()
                }
            }
        }
    }
}
