参考：点击打开链接但我按这篇修改时会出现下拉后不能响应上拉事件的问题

在SwipeRefreshLayout中嵌套webview时，默认无论在网页任何位置下拉都会触发刷新，实际需求是只在顶部需要，解决方法是继承SwipeRefreshLayout,复写其中的canScrollUp方法：

import android.content.Context;import android.support.v4.widget.SwipeRefreshLayout;import android.util.AttributeSet;import android.view.ViewGroup;public class ScrollSwipeRefreshLayout extends SwipeRefreshLayout {    //子布局 这里为webview    private ViewGroup mChildViewGroup;    public ScrollSwipeRefreshLayout(Context context) {        super(context);    }    public ScrollSwipeRefreshLayout(Context context, AttributeSet attrs) {        super(context, attrs);    }    public ViewGroup getViewGroup() {        return mChildViewGroup;    }    public void setViewGroup(ViewGroup viewGroup) {        this.mChildViewGroup = viewGroup;    }    /**     * @return Whether it is possible for the child view of this layout to     *         scroll up. Override this if the child view is a custom view.     */    @Override    public boolean canChildScrollUp() {        if(mChildViewGroup != null){            //子布局在非顶部才可以向上滚动            if(mChildViewGroup.getScrollY() > 0){                return true;            }        }        return false;    }}

然后在使用时传入webview即可：

refreshLayout.setViewGroup(webView);//设置监听滚动的子view
