KerningViews

KerningViews provides a set of views (currently only TextView and Button) which lets you adjust the spacing between the characters in the text of that view also know as Kerning.

Kerning is a common feature in designing apps like Photoshop or Sketch, but Android natively doesn't allow Kerning. Since API level 21, Android allows you to do this using setLetterSpacing attribute , but there is no way to achieve this in pre-21 devices.

KerningViews provides a simple API to achieve this feature in TextView and Button text accross all API levels in Android.

Screenshot

This screenshot is from the sample app showing different text with different Kerning factors.

Download

This library is available in jCenter which is the default Maven repository used in Android Studio.

dependencies {

  // other dependencies here

 compile 'com.andrognito.kerningview:kerningview:1.0.0' 
}

Usage

You should see the sample app for complete usage details. You can either use these views and set the attribute via XML or programatically change the kerning factor as required.

XML

Just use the KerningTextView or KerningButton in your XML layouts. If you do not put the kv_spacing attribute then it will behave as a normal TextView with no letter spacing.

You can customize the letter spacing by using the kv_spacing atribute with different kerning facctor (including floating point values).

<com.andrognito.kerningview.KerningTextView

  android:id="@+id/text1"

  android:layout_width="wrap_content"

  android:layout_height="wrap_content"

  android:fontFamily="sans-serif"

  android:text="@string/sample_text_1"

  android:textSize="@dimen/text_size_xlarge"

  app:kv_spacing="10" />

JAVA

Just reference the views from your layout and use the setter to change the letter spacing of the texts.

KerningTextView mText = (KerningTextView) findViewById(R.id.text);
  if (mText != null) {

mText.setKerningFactor(3.5f);
 
}

Contribution

This is a very simple and tiny library that solves a simple usecase. But I would love to accept contributions to improve or add functionality to it.
