pull-to-refresh

I've implemented a straight forward WKWebView in iOS. var refreshControl = UIRefreshControl() refreshControl.addTarget(self, action: Selector("refreshWebView"), forControlEvents: UIControlEvents.ValueChanged) This is in viewDidLoad() And the corresponding refreshWebView function. But when I run it on mobile or simulator, no matter how much I drag, there is no pull to refresh action. Nothing is triggered, and it almost feels like I am stuck to the upper bounds of the screen. Where can be going wrong? Try to change your code like this, If you want to pull to refresh the webView you need to

Does anyone have a simple example on how to use SwipeRefreshLayout with a ListView? Here is my situation: I have a class SynchDogs that pulls data from the server. So that class serves as the source for my adapter. I want to use SwipeRefreshLayout for refreshing the adapter and so the ListView. DogActivity is an Observer of SynchDogs so that DogActivity implements an update method that is called when new data is ready. So I implement onRefresh as @Override public void onRefresh() { SynchDogs.getInstance().synchronizeWithServer(); } So I am supposing this is all I need to initiate the start of

Does anyone has practice of using Pull to refresh list with Pinned section header ? I use Android-PullToRefresh lib with my list and I want to add ability of showing pinned section header at the top of list. I used PinnedHeaderListView lib in another project for pinned section. But I can't combine these two libraries into one. Is Android-PullToRefresh can show pinned section header? Perhaps any other Pull to refresh lib can do it? It's possible to integrate the Actionbar-PullToRefresh library with the StickyListHeaders library, but you need to use a custom Delegate in order to get Actionbar

I'm trying to get the pull to refresh feature working properly on iOS 7 in my Table View. On viewDidLoad, I have: self.refreshControl = [[UIRefreshControl alloc] init]; [self.refreshControl addTarget:self action:@selector(refreshInvoked:forState:) forControlEvents:UIControlEventValueChanged]; I then run: -(void) refreshInvoked:(id)sender forState:(UIControlState)state { // Refresh table here... [_allEntries removeAllObjects]; [self.tableView reloadData]; [self refresh]; } When the request that the refresh method invokes is done, in the didCompleteRequest code, I have: [self.refreshControl

I am trying to implement pull-to-refresh in Android. I know there is SwipeRefreshLayout but with all the newly designed Google apps like Drive (see attached) for Lollipop, I have noticed there is a new refresh icon that comes in the view when pulled. I tried looking it online but in vain. Has Android released this as a part of the Material Design? Any ideas about how to implement it? EDIT: Some people have pointed out how this is a duplicate of How to implement a Pull-to-refresh . It is not the same question. You'll see it if you read the question properly. This is SwipeRefreshLayout . Version
