Animating Android Apps Effortlessly with android-tnranimationhelper Library

Robert Harris -

In the realm of Android development, animation is a key aspect that enhances user experience and engagement. The open-source library android-tnranimationhelper, brought to life by Thunderrise, simplifies the integration of common animations in Android applications using the native Android animation library.

Here's a glimpse into the core offerings of android-tnranimationhelper library:

  1. Rotation Animation: Animate the rotation of a view smoothly.
  2. Scale Animation: Effortlessly scale views to a desired size.
  3. Translation Animation: Translate views across the screen with ease.
  4. Alpha Animation: Adjust the transparency of views for a fading effect.
  5. Color Animation: Transition between colors to add a visual appeal.

Implementing animations is a breeze with android-tnranimationhelper. Simply import the library into your Android project, and you are good to go:

// Adding dependency in build.gradle
dependencies {
    implementation 'com.github.thunderrise:android-tnranimationhelper:-SNAPSHOT'
}

// Utilizing animation in code
import com.github.thunderrise.android.tnranimationhelper.TnrAnimationHelper;

// Create animation instance
TnrAnimationHelper animationHelper = new TnrAnimationHelper();

// Set animation properties
animationHelper.setRotation(rotation);
animationHelper.setScale(scale);
animationHelper.setTranslation(translation);
animationHelper.setAlpha(alpha);
animationHelper.setColor(color);

// Kickstart the animation
animationHelper.start();

Executing the above snippet initiates the specified animation on the targeted view.

The android-tnranimationhelper library extends its utility with additional features:

  • Animation Actions: Define custom actions for a more controlled animation experience.
  • Animation Listener: Monitor animation lifecycle events such as start and end, for better control and response.
