同步RelativeLayout内两个ScrollViews的滚动

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <!-- ScrollView1的内容 -->

    </ScrollView>

    <ScrollView
        android:id="@+id/scrollView2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/scrollView1">

        <!-- ScrollView2的内容 -->

    </ScrollView>

</RelativeLayout>

ScrollView scrollView1 = findViewById(R.id.scrollView1);
ScrollView scrollView2 = findViewById(R.id.scrollView2);

scrollView1.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
    @Override
    public void onScrollChanged() {
        // 处理ScrollView1的滚动事件
        int scrollY = scrollView1.getScrollY();
        scrollView2.scrollTo(0, scrollY);
    }
});

scrollView2.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
    @Override
    public void onScrollChanged() {
        // 处理ScrollView2的滚动事件
        int scrollY = scrollView2.getScrollY();
        scrollView1.scrollTo(0, scrollY);
    }
});
