我不确定这是不是问题，但你应该在其他所有事情之后最后调用loadUrl。此外，您似乎使用shouldOverridemethod循环您的webview，检查我的版本

    webviewdevelopment = (WebView) findViewById(R.id.webViewdevelopment);
    webviewdevelopment.setWebViewClient(new myWebClient());
    webviewdevelopment.getSettings().setJavaScriptEnabled(true);
    webviewdevelopment.loadUrl("http://stackoverflow.com");

public class myWebClient extends WebViewClient {
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        super.onPageStarted(view, url, favicon);
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

        Uri uri;

        try {
            uri = Uri.parse(url);
        } catch (NullPointerException e) {
            // let Android deal with this
            return true;
        }

        String host = uri.getHost(); //Host is null when user clicked on email, phone number, ...

        if (host != null && host.equals("stackoverflow.com")) {
            // This is my web site, so do not override; let my WebView load the page.  
            return false;
        }
        else {
            // You should consider this, since you are using JavaScript.. you may make your users vulnerable 
            // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs or anything else (email, phone number, ...)
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            startActivity(intent);
            return true;
        }

    }
}

Android WebView找不到kitkat和棒棒糖的预期效果
