问题 I got an empty UICollectionView, which means the cell count is 0 in it. I intended to do so, so when no usable data, numberOfItemsInSection will return 0. Then user can choose to Pull to refresh if no data available. (content size is smaller than screen height, excluding the PullToRefresh arrow views) My problem is if there is at least one cell, pull to refresh works perfect, but when no cell, I cannot pull to refresh. I am not sure how to do it, or if the cell count impact the pullToRefresh?

问题 I've got Android's SwipeRefreshLayout working and am trying to customize the colors across all the pull to refreshes throughout the app. In order to follow the DRY principle, I've tried moving the desired colors to array.xml as follows: <resources> <array name="swipeRefreshColors"> <item>@color/pink</item> <item>@color/green</item> </array> </resources> However, when I try and import them into the swipe to refresh: swipeRefreshLayout.setColorSchemeResources(R.array.swipeRefreshColors); I get

问题 is it possible to replace the Icon of the Pull-To-Reload, the circle-arrow, with something else? I'd like to have something like a trash-can instead. Thanks, Georg 回答1: If you are using the SwipeRefreshLayout, it seems there is no way to change the icon or animation for it yet. You can change the colors for the animation of spinning lines with the setColorSchemeColors method. Some external pull to refresh libraries do let you do it, like Ultra Pull to Refresh by liaohuqiu. It seems to allow a
