获取RecyclerView或Webview的滚动Y

问题描述

我已经在Recyclerview中创建了活动Webview内容.当我滚动Webview时，我想获得Y滚动位置.我尝试了Webview.getScrollY()，Webview.getY()，RecyclerView.getScrollY()，RecyclerView.getY()，...，但是效果不佳.我无法获得当前的滚动Y.有没有建议获取Webview或RecyclerView的滚动Y?

I have created a activity Webview content placed in Recyclerview.I want to get the scroll Y position when I scroll webview.I tried Webview.getScrollY(), Webview.getY(), RecyclerView.getScrollY(), RecyclerView.getY(),... but it do not work fine. I can't get current scroll Y.Is there any suggest for get scroll Y of Webview or RecyclerView ?

推荐答案

使用 RecyclerView.OnScrollListener 用于RecyclerView和用于网络视图的View.OnScrollChangeListener .

Use a RecyclerView.OnScrollListener for the RecyclerView and a View.OnScrollChangeListener for the webview.

您必须自己跟踪总滚动，像这样:

You'll have to keep track of the total scroll yourself, like this:

private int mTotalScrolled = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    ...

    recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);

                mTotalScrolled += dy;

            }
        });

    ...

}

private int getScrollForRecycler(){
    return mTotalScrolled;
}
