可以加个NPE保护代码么？

huxq17 commented 7 years ago

我是想知道refreshLayout 在哪些地方find id 的。找不到根本原因加npe保护代码也没用啊。

hurricane08 commented 7 years ago

场景是：pageView，每一页是个FrameLayout，refreshLayout是其子view，然后find id的代码在这个FrameLayout的onFinishInflate中

@Override
    protected void onFinishInflate() {
        super.onFinishInflate();
        ……
        refreshLayout = ViewUtils.findViewById(this, R.id.article_refresh_layout);
        refreshLayout.setMoveForHorizontal(true);
        refreshLayout.setPullRefreshEnable(true);
        refreshLayout.setAutoLoadMore(true);

您好setOverScrollMode() 这个问题您解决了吗？
