SwipeRefreshLayout设置首次进入页面开启动画

SwipeRefreshLayout自带的刷新动画简洁大方,于是决定用来替换UI的加载动画.可设置setRefreshing(true); 竟然没用.查了下原因是因为页面刚启动还没有测量到动画显示的坐标.

解决办法:

• 第一种常见的:

swipeRefreshLayout.post(new Runnable() {   @Override   public void run() {      swipeRefreshLayout.setRefreshing(true);   }});

切记:关闭时也使用:

swipeRefreshLayout.post(new Runnable() {   @Override   public void run() {      swipeRefreshLayout.setRefreshing(false);   }});

• 第二种办法,手动通知SwipeRefreshLayout去测量

swipeRefreshLayout.measure(0,0);swipeRefreshLayout.setRefreshing(true);
