我想通了。
由于我在onCreate中使用setText到TextView，因此调用.scrollTo不起作用。
所以现在我使用以下代码：

sView.post(new Runnable() {
    @Override
    public void run() {
        sView.scrollTo(sViewX, sViewY);
    } 
});

在绘制元件之前，不应开始滚动，因为只有在未创建元件时，滚动才起作用：

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    scrollView.scrollTo(....

onRestoreInstanceState（）只是太早滚动视图。这就是为什么发布新的Runnable会有帮助，但并不总是如此。有时候我们甚至必须使用postDelayed（）才能让它工作。对于Fragment，我们可以使用onViewCreated（）代替：

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    sViewX = savedInstanceState.getInt("sViewX");   
    sViewY = savedInstanceState.getInt("sViewY");
    sView.scrollTo(sViewX, sViewY);
}

这对我很有效

@Override
protected void onSaveInstanceState(Bundle outState) {
    outState.putInt(SystemGlobal.SCROLL_Y, mRelativeLayoutMain.getTop());
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onRestoreInstanceState(savedInstanceState);
    mRelativeLayoutMain.scrollTo(0, savedInstanceState.getInt(SystemGlobal.SCROLL_Y));
}

这个代码为我工作的动态滚动标签，也许这将是有用的

TabHost tabHost;
int currentActiveTab;
HorizontalScrollView tabsHorizontalScrollView;
//some code ...
tabHost = getTabHost();
tabsHorizontalScrollView = findViewById(R.id.tabsHorizontalScrollView);
currentActiveTab = 8;
//some code ...
tabHost.setCurrentTab(currentActiveTab);
tabHost.getTabWidget().getChildAt(currentActiveTab).post(new Runnable() {
  @Override
  public void run() {
    tabsHorizontalScrollView.scrollTo(tabHost.getTabWidget().getChildAt(currentActiveTab).getLeft(), tabsHorizontalScrollView.getScrollY());
  }
});

对于MVVMCross：

protected override void OnSaveInstanceState(Bundle outState)
{
    base.OnSaveInstanceState(outState);

    ScrollView sv = FindViewById<ScrollView>(Resource.Id.dispatchScrollView);
    int posY = sv.ScrollY;

    outState.PutInt("scrollY", posY);
}

protected override void OnRestoreInstanceState(Bundle savedInstanceState)
{
    base.OnRestoreInstanceState(savedInstanceState);

    ScrollView sv = FindViewById<ScrollView>(Resource.Id.dispatchScrollView);
    int posY = savedInstanceState.GetInt("scrollY");

    sv.Post(new Runnable(new Action(() => sv.ScrollTo(0, posY))));
}

您可以在全局布局回调中滚动视图，而不是将滚动操作发送到下一个run-loop：

@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    sView.getViewTreeObserver().addOnGlobalLayoutListener(
        new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                sView.scrollTo(sViewX, sViewY);
            }
        }
    );
}
