使用

设置RecyclerView的LayoutManager，并配置翻页模式

<androidx.recyclerview.widget.RecyclerView
        ...
        app:layoutManager="com.sclimin.recycler.flip.FlipLayoutManager"
        // 翻页模式
        android:orientation="vertical"
        或
        android:orientation="horizontal"
        ... />

Page中RootView必须使用实现FlipLayout接口的Layout

<?xml version="1.0" encoding="utf-8"?>
<com.sclimin.recycler.flip.FlipSampleLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    ...
    
</com.sclimin.recycler.flip.FlipSampleLayout>

自定义FlipLayout：

public class FlipSampleLayout extends FrameLayout implements FlipLayout {

    private FlipLayoutHelper mHelper;

    ...

    @Override
    protected void onSizeChanged(int w, int h, int ow, int oh) {
        super.onSizeChanged(w, h, ow, oh);
        mHelper.sizeChanged(w, h);
    }

    @Override
    public void draw(Canvas canvas) {
        if (mHelper.draw(canvas)) {
            return;
        }
        super.draw(canvas);
    }

    @Override
    public void drawSuper(Canvas canvas) {
        super.draw(canvas);
    }
}
