将两个recyclerView滚动为一个

// 布局文件中的代码
<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recyclerView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recyclerView2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </LinearLayout>
</ScrollView>

// 在代码中的实现
RecyclerView recyclerView1 = findViewById(R.id.recyclerView1);
RecyclerView recyclerView2 = findViewById(R.id.recyclerView2);

// 设置布局管理器和适配器
recyclerView1.setLayoutManager(new LinearLayoutManager(this));
recyclerView1.setAdapter(adapter1);

recyclerView2.setLayoutManager(new LinearLayoutManager(this));
recyclerView2.setAdapter(adapter2);

// 监听RecyclerView的滚动事件
recyclerView1.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
        super.onScrolled(recyclerView, dx, dy);
        // 根据滚动的偏移量，来滚动第二个RecyclerView
        recyclerView2.scrollBy(dx, dy);
    }
});

recyclerView2.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
        super.onScrolled(recyclerView, dx, dy);
        // 根据滚动的偏移量，来滚动第一个RecyclerView
        recyclerView1.scrollBy(dx, dy);
    }
});
