谷歌官方刷新组件SwipeRefreshLayout

今天开始使用谷歌的SwipeRefreshLayout，会记下一些坑

1.手动调用setRefreshing(true)不会出现刷新动画

原因是：SwipeRefreshLayout indicator does not appear when the setRefreshing(true) is called before the SwipeRefreshLayout.onMeasure()

解决方法是：http://stackoverflow.com/questions/26858692/swiperefreshlayout-setrefreshing-not-showing-indicator-initially

mSwipeRefreshLayout.setProgressViewOffset(false, 0,
                (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 24, getResources().getDisplayMetrics()));
mSwipeRefreshLayout.setRefreshing(true);

 或者

mSwipeRefreshLayout.ponst(new Runnable(){
        public void run(){
            mSwipeRefreshLayout.setRefreshing(true);
        }
});

个人推荐第二种方法，第一种方法有时候会出现bug
