Zoomy is an easy to use pinch-to-zoom library for Android.
-
You project should build against Android 4.1.x (minSdkVersion 16).
-
Add the JitPack repository to your project's build.gradle file:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}- Add the dependency in your app's build.gradle file:
dependencies {
implementation 'com.github.moisoni97:Zoomy:2.0.0'
}Register the view you want to be zoomable:
Zoomy.Builder builder = new Zoomy.Builder(this).target(imageView);
builder.register();Unregister the view:
Zoomy.unregister(imageView);That's all. Now your views can be pinch-zoomed!
- Use ZoomyConfig to change default configuration flags:
ZoomyConfig config = new ZoomyConfig();
config.setZoomAnimationEnabled(false); //enables zoom out animation when view is released
config.setImmersiveModeEnabled(false); //enables immersive mode when zooming a view
Zoomy.setDefaultConfig(config); //set the configuration across all `Zoomy` registered views- Zoomy Builder also allows some customization:
Zoomy.Builder builder = new Zoomy.Builder(this)
.target(imageView)
.enableImmersiveMode(false)
.animateZooming(false);- Add callbacks to listen for specific events:
Zoomy.Builder builder = new Zoomy.Builder(this)
.target(imageView)
.tapListener(new TapListener() {
@Override
public void onTap(View v) {
//view tapped, do stuff
}
})
.longPressListener(new LongPressListener() {
@Override
public void onLongPress(View v) {
//view long pressed, do stuff
}
}).doubleTapListener(new DoubleTapListener() {
@Override
public void onDoubleTap(View v) {
//view double tapped, do stuff
}
})
.zoomListener(new ZoomListener() {
@Override
public void onViewStartedZooming(View view) {
//view started zooming
}
@Override
public void onViewEndedZooming(View view) {
//view ended zooming
}
});- Change the interpolator used to animate ending zoom event:
Zoomy.Builder builder = new Zoomy.Builder(this)
.target(imageView)
.interpolator(new OvershootInterpolator());Licensed under the Apache License, Version 2.0 (the "License");
