Download

gradle:

compile 'com.github.irshulx:glitch-text-effect:1.0.1'

or maven:

<dependency>
  <groupId>com.github.irshulx</groupId>
  <artifactId>glitch-text-effect</artifactId>
  <version>1.0.1</version>
  <type>pom</type>
</dependency>

A gist of this library is available at https://gist.github.com/irshuLx/138c1dc0af5262e3ca0c5f5db014d7ef

Usage

<com.github.irshulx.glitchtext.GlitchTextEffect
    android:layout_width="match_parent"
    app:text="PURGE"
    app:noise="7"
    app:textColors="@array/glitch_colors"
    app:textSize="27"
app:speed="70"
    android:layout_height="match_parent" />

or programmatically:

List<Integer> colors = new ArrayList<>();
    colors.add(R.color.colorPrimaryDark);
    colors.add(R.color.colorPink);
    colors.add(R.color.colorLightBlue);
    colors.add(R.color.colorFront);
    
    GlitchTextEffect effect = new GlitchTextEffect(this,colors,"PURGE");
    effect.setTextSize(60);
effect.setSpeed(70); //duration of a single cycle animation
    effect.setNoise(6); //the noise quotient of the effect
    effect.start();     // required to call for programmatic initiation
    layout.addView(effect);

The logic is to stack textviews on a FrameLayout and animate their positions in opposite directions. The no. of textviews added is proportional to the number of colors in the array.

API

void setTextSize(int size);    // set the textsize in sp

void setNoise(int level);     // set the noise level, recommended between 5-10

void setFontFile(String fileName); // set the font to be used, eg: "fonts/Poppins-Black.ttf"

void setSpeed(int speed); // speed in ms, recommends 50-200
