material-scrolling
Android library for material scrolling techniques.
Features
- Easily implement material scrolling techniques with RecyclerView.
- Customize the behavior while scrolling.
- Support RecyclerView in ViewPager.
Usage
(For a working implementation of this project see the sample.)
MaterialScrollingLayout
Layout ObservableRecyclerView inside of MaterialScrollingLayout.
<jp.satorufujiwara.scrolling.MaterialScrollingLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/materialScrollingLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:ms_flexible_height="240dp"
>
<com.github.ksoichiro.android.observablescrollview.ObservableRecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</jp.satorufujiwara.scrolling.MaterialScrollingLayout>
ms_flexible_heightis height from RecyclerViews top to RecyclerView's first item.
And call MaterialScrollingLayout.addBehavior(View, Behavior) in Activity or Fragment.
First argument is target View. Second argument is View's behavior while scrolling.
materialScrollingLayout.addBehavior(bgImageView, new ParallaxBehavior());
materialScrollingLayout.addBehavior(titleTextView, new ScrollingBehavior());
materialScrollingLayout.addBehavior(fabView, new FabBehavior(getResources()));
FabBehavior is customized Behavior. If you want customize behavior, create class that extends 'Behavior'.
public class TitleBehavior extends Behavior {
private final int scrollLimitHeight;
public TitleBehavior(Resources r) {
scrollLimitHeight = r.getDimensionPixelOffset(R.dimen.title_scroll_height);
}
@Override
protected void onScrolled(View target, int scrollY, int dy) {
ViewCompat.setTranslationY(target, -Math.min(scrollY, scrollLimitHeight));
}
}
MaterialViewPager
If you want to use with ViewPager, use MaterialViewPager.
And PagerAdapter must imptelement MaterialScrollingViewPager.ContainRecyclerViewPagerAdapter.
<jp.satorufujiwara.scrolling.MaterialScrollingViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:ms_flexible_height="240dp"
app:ms_base_height="48dp"
/>
And call MaterialScrollingViewPager.addBehavior(View, Behavior) in Activity or Fragment.
