pull-to-refresh

问题 I have a TableView embedded in NavigationController (and that's embedded in a TabBar Controller). I have a username button in each cell that segues to the user's profile. However after I hit 'back' on the profile page's nav bar, and gets directed back to tableview, it seems like I bugged something. And if I pull down again, it refreshs but this time, top row's username becomes unclickable while other rows work as expected. Please note that I call self.theRefreshControl = UIRefreshControl() in

问题 Note: This question was already asked here. which did not get any answer so I decided to repost it with my code. I want a webView to refresh the current page when a user pulls down the screen from the top which is working fine. The problem is the loading progress bar isn't stopping after the page has been loaded. Here's the MainActivity.java // Swipe to Refresh SwipeRefreshLayout swipeLayout = (SwipeRefreshLayout)this.findViewById(R.id.swipeToRefresh); swipeLayout.setOnRefreshListener(new

问题 I've this weird app crash when pulling to refresh occurs. My code goes as it follows: var posts: [Posts] = [] override func viewDidLoad() { super.viewDidLoad() // refreshControl -> pull to refresh handler let refreshControl = UIRefreshControl() refreshControl.addTarget(self, action: #selector(Main_TVC.getData), for: UIControlEvents.valueChanged) self.refreshControl = refreshControl getData() } override func numberOfSections(in tableView: UITableView) -> Int { return 1 } override func

问题 Can we implement pull to refresh feature on a custom view controller?. My view controller is not a table view controller and I want to refresh this view on pulling the screen down. How can I implement this feature? 回答1: In short, you need to do the following: Embed your view in a UIScrollView . Set your controller as the delegate of the scroll view. Add a "Pull To Refresh" subview to the scroll view such that its frame is off the top of the screen. Something like CGRectMake(0, -30, 320, 30)

问题 I have a custom horizontal collection view that has 1 row and I want to add pull to refresh functionality which, by default, appears above my row of cells. I would like the user to be able to pull the collection view from left to right to activate the UIRefreshControl. Any ideas? 回答1: For this you need to implement the UIScrollViewDelegate method - (void)scrollViewDidScroll:(UIScrollView *)scrollView { CGPoint offset = scrollView.contentOffset; CGRect bounds = scrollView.bounds; CGSize size =

问题 I am using pullToRefreshLibrary provided by Chris Banes. I have gridView which is containg whole list of data. I tried pullToRefreshGridViewActivity but it was too slow so I am trying to use pullToRefreshScrollViewActivity over my gridView to handle it. The problem is that when I do so, scrollView is handling all touch events and I cannot swipe over gridView. I need to lock it and pass touches to gridView. here is my xml : <com.handmark.pulltorefresh.library.PullToRefreshScrollView xmlns:ptr=

问题 I built my project using the Android Studio start options (Automatically builds the action bar with the tabs) so a bit is generated for me. I did however implement a list-view fragment for each one of the tabs that uses custom adapters . I'm having a trouble adding the pull-to-refresh lib from Chris Bane. Maybe I'm importing it wrong? I'm fairly new at android development and especially with this new Gradle stuff. I'm Importing the github repository in the build.gradle file here: apply plugin
