TypedTextView

Custom implementation of Android's TextView simulating a keyboard/typewriter.

Features

  • display a blinking cursor after every character typed.
  • characters are displayed on the screen with random speed which simulates human behavior.
  • emit audio keystrokes with typed characters.
  • Lifecycle-aware component. Character typing and audio stops/resumes as per Activity/Fragment state.
  • support to maintain state across Activity/Fragment lifecycle.
  • delay on sensing comma(,) and full stops(.) to simulate user pauses.
  • display sentences on new line on sensing full stops in passed text.

Gradle

  • Step 1. Add the JitPack repository to your build file.

Add following in your Project level build.gradle at the end of repositories:

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}
  • Step 2. Add the dependency
dependencies {
  ...
  implementation 'com.github.iamporus:TypedTextView:x.y.z'
}
