我正在制作应用程序＆amp;我需要在2-3秒内刷新Webview。如何使webview自动刷新请用示例代码发布您的答案。谢谢。

这是我的代码......检查

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final WebView myWebView = (WebView) findViewById(R.id.myWebView);

   The target url to surf using web view
    String url = "www.mywebsite.com";


    myWebView.loadUrl(url);



    // Enable java script on web view
    myWebView.setWebChromeClient(new WebChromeClient());
    myWebView.setWebViewClient(new WebViewClient());
    myWebView.getSettings().setJavaScriptEnabled(true);

    myWebView.getSettings().setUserAgentString("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36");

    final String js = ""
    myWebView.setWebViewClient(new WebViewClient(){
        /*
            void onPageFinished (WebView view, String url)


        public void onPageFinished(WebView view, String url){
            super.onPageFinished(view, url);
            if(url.contains("/nextpage")) {
                myWebView.clearHistory();
                myWebView.clearCache(true);
                myWebView.clearView();
                myWebView.destroy();
                //finish();
                //System.exit(0);
            }

            if(Build.VERSION.SDK_INT >= 19){

                view.evaluateJavascript(js, new ValueCallback<String>() {
                    @Override
                    public void onReceiveValue(String s) {
                    }
                });
            }
        }
    });
}

你能每隔2-3秒调用一次WebView.loadUrl（）吗？那是https://stackoverflow.com/a/2563482/2848676
