我用 android.support.v4.widget.SwipeRefreshLayout 与 android.support.v7.widget.RecyclerView 。照片 在片段视图创建我需要证明 SwipeRefreshLayout 动画。但是，当我打电话 setRefreshing（真）没有任何反应。但是，当我刷新数据的动态变化。 我想，动画没有显示无子里面 SwipeRefreshLayout 。 如何显示这个动画的最佳方式？

I'm using android.support.v4.widget.SwipeRefreshLayout with android.support.v7.widget.RecyclerView. On fragment view creation I need to show SwipeRefreshLayout animation. But when I call setRefreshing(true) nothing happens. But when I refresh data animation changes. I suppose that the animation isn't showing without child inside SwipeRefreshLayout. How to show this animation in the best way?

谢谢你，伙计们。

I`ve只是意识到，最简单的解决方法是调用setRefreshing（真）之前调用方法测量（INT，INT）非零值）。问题发生，因为setRefreshing（真）的onMeasure之前调用。

I`ve just realised that the easiest solution is to call method measure(int, int) with non-zero values) before calling setRefreshing(true). The problem is happening because setRefreshing(true) is calling before onMeasure.

所以，你需要调用：

swipeRefreshLayout.measure(initialWidth, initialHeight);
swipeRefreshLayout.setRefreshing(true);
