Question

我有静态import UIKit import WebKit class ViewController: UIViewController { @IBOutlet weak var webView: WKWebView! override func viewDidLoad() { super.viewDidLoad() let url = URL(string: "https://mit.gsv.dk")! webView.load(URLRequest(url: url)) var scrw = webView.bounds.size.width scrw = 2000 /* let javascript = "document.querySelector('meta[name=viewport]').setAttribute('content', 'width=\(scrw);', false); " webView.evaluateJavaScript(javascript) */ var scriptContent = "var meta = document.createElement('meta');" scriptContent += "meta.name='viewport';" scriptContent += "meta.content='width=device-width';" scriptContent += "document.getElementsByTagName('head')[0].appendChild(meta);" webView.evaluateJavaScript(scriptContent, completionHandler: nil) } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() } }＆amp; ArrayList从CustomAdapter

访问它

Broadcastreceiver

当数据被更改时，我的public static ArrayList<AppDetail> apps; public static CustomAdapter adapter;被调用，我的列表更新了新项目，但RecyclerView显示旧数据新项目未被看到

Broadcastreceiver

这是我的public class AppListener extends BroadcastReceiver { @Override public void onReceive(Context context, Intent arg1) { // TODO Auto-generated method stub Log.d("Akshay", "there is a broadcast"); apps=null; loadApps(context); }函数

loadApps()

您好@Akshay Katariya可以尝试下面的代码

private void loadApps(Context context){
    if (apps == null)
        {
            if(adapter != null)
            adapter.notifyDataSetChanged();
            else
            yourRecyclerviewObject.setadapter(adapter);

        }
    }
}

请检查。

RecyclerView adapter.notifyDataSetChanged（）无法使用BroadcastReceiver
