Scrolling Background View

Endless background scrolling for Android

Please note, that first GIF uses library: CCF to achive color-cross-fade effect, please refer to the sample project for more info.

Version Gradle
Maven Central compile 'ru.noties:sbv:x.x.x'

A simple Android View that can help to achive endless scrolling background effect. It takes one drawable and tiles it to fill to the width & height of the view.

<ru.noties.sbv.ScrollingBackgroundView
    android:id="@+id/scrolling_background_view"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:sbv_drawable="@drawable/tile_pager"
    app:sbv_scrollX="0dip"
    app:sbv_scrollY="0dip"/>

Custom attributes:

  • sbv_drawable - the drawable object to be used
  • sbv_scrollX - start scroll x value
  • sbv_scrollY - start scroll y value

This view works with preview layout tools in Android Studio.

Next we need to redirect scroll events from our scrolling View to the ScrollingBackgroundView. The sample project contains some basic cases like RecyclerView & ViewPager.

final ScrollingBackgroundView scrollingBackgroundView = findView(view, R.id.scrolling_background_view);

scrollingBackgroundView.setDrawable(/* drawable reference */);

scrollingBackgroundView.setOnSizeChangedListener(/* a listener to be notified about size changes of this view */);

// actual scrolling methods
scrollingBackgroundView.scrollBy(/* x & y values */);
scrollingBackgroundView.scrollTo(/* x & y values */);

scrollingBackgroundView.scrollX(); // use this method to retrieve current scroll x value
scrollingBackgroundView.scrollY(); // use this method to retrieve current scroll y value
final RecyclerView recyclerView = findView(view, R.id.recycler_view);
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        scrollingBackgroundView.scrollBy(dx, dy);
    }
});
