OverScroll

利用CoordinatorLayout+Behavior实现列表弹性滚动和惯性滚动效果(类似微信首页)，支持水平和垂直方向的滚动，效果如下：

Usage 用法

Gradle

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}
 
dependencies {
    implementation 'com.github.1993hzw:OverScroll:1.1.1'
}

在xml布局文件中添加类似代码:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    ...

    <cn.forward.overscroll.view.OverScrollVerticalRecyclerView
        android:background="#0ff"
        android:id="@+id/overscroll_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    ...

</android.support.design.widget.CoordinatorLayout>

当然你可以在CoordinatorLayout中使用OverScrollHorizontalRecyclerView, OverScrollVerticalRecyclerView 或 OverScrollScrollView．

现在你的布局就实现了弹性滚动和惯性滚动效果啦！

拓展

IOverScrollView overScrollView = findViewById(R.id.overscroll_view);
overScrollView.setOverScrollCallback(new IOverScrollCallback() {
    @Override
    public boolean canScroll(IOverScroll overScroll, View child, int scrollDirection) {
       ...
    }

    @Override
    public int getMaxFlingOffset(IOverScroll overScroll, View child, int scrollDirection) {
        ...
    }

    @Override
    public float getDampingFactor(IOverScroll overScroll, View child, int scrollDirection) {
        ...
    }

    @Override
    public int getMinFlingVelocity(IOverScroll overScroll, View child, int scrollDirection) {
        ...
    }

    @Override
    public void onOffsetChanged(IOverScroll overScroll, View child, int offset) {
        ...
    }

    @Override
    public boolean onSpringBack(IOverScroll overScroll, View child) {
        ...
    }

    @Override
    public void onStopSpringingBack(IOverScroll overScroll, View child) {
        ...
    }
});

overScrollView.addOffsetChangeListener(new IOffsetChangeListener() {
    @Override
    public void onOffsetChanged(View child, int offset) {
        ...
    }
});
