material-scrolling

Android library for material scrolling techniques.

Features

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.
