Question

我正在开发在webview中加载url的应用程序。

代码是：

web = (WebView) findViewById(R.id.myWeb);
        web.resumeTimers();
        final WebSettings settings = web.getSettings();
        settings.setJavaScriptEnabled(true);
        settings.setLoadWithOverviewMode(true);
        settings.setUseWideViewPort(true);
        settings.setRenderPriority(WebSettings.RenderPriority.HIGH);
        settings.setSupportZoom(true);
        settings.setBuiltInZoomControls(true);
        settings.setPluginState(android.webkit.WebSettings.PluginState.ON_DEMAND);
        web.setWebViewClient(new myWebClient());
        web.loadUrl(url);

班级代码

public class myWebClient extends WebViewClient {
    @Override
    public void onPageFinished(WebView view, String url) {

        super.onPageFinished(view, url);
    }


    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        // TODO Auto-generated method stub

        super.onPageStarted(view, url, favicon);
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // TODO Auto-generated method stub

        view.loadUrl(url);
        return true;

    }
}

我已经添加了INTERNET权限并完成了android：hardwareAccelerated =＆＃34; true＆＃34;但它仍然给出错误：android 4.2.2上没有网页。我也检查了互联网连接。

在其他版本如4.4.2和4.0.4网页上正在加载。

实现webView.setWebViewClient，如下所示：

webView.setWebViewClient(new WebViewClient() {

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return false;
        }

@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error){
        handler.proceed(); 
       }
});

}

它对我有用。

android 4.2.2 loadurl网页未显示
