An Android view for displaying repeated continuous side scrolling images. This can be used to create a parallax animation effect.
##Installation Step 1. Add the JitPack repository to your build file
repositories {
// ...
maven { url "https://jitpack.io" }
}Step 2. Add the dependency in the form
dependencies {
compile 'com.github.Q42:AndroidScrollingImageView:1.0'
}In your Android layout file add:
<com.q42.android.scrollingimageview.ScrollingImageView
android:id="@+id/scrolling_background"
android:layout_width="match_parent"
android:layout_height="wrap_content"
scrolling_image_view:speed="1dp"
scrolling_image_view:src="@drawable/scrolling_background" />Don't forget to add the namespace to your root XLM element
xmlns:scrolling_image_view="http://schemas.android.com/apk/res-auto"In your Java code you can start and stop the animation like this:
ScrollingImageView scrollingBackground = (ScrollingImageView) loader.findViewById(R.id.scrolling_background);
scrollingBackground.stop();
scrollingBackground.start();In order to achieve a parallax effect you can stack multiple ScrollingImageView's in a FrameLayout with diffirent speeds, for example:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.q42.android.scrollingimageview.ScrollingImageView
android:id="@+id/scrolling_background"
android:layout_width="match_parent"
android:layout_height="wrap_content"
scrolling_image_view:speed="1dp"
scrolling_image_view:src="@drawable/scrolling_background" />
<com.q42.android.scrollingimageview.ScrollingImageView
android:id="@+id/scrolling_foreground"
android:layout_width="match_parent"
android:layout_height="wrap_content"
scrolling_image_view:speed="2.5dp"
scrolling_image_view:src="@drawable/scrolling_foreground" />
</FrameLayout>
