setContentView(R.layout.web_view);
WebView webview = (WebView)findViewById(R.id.webview);
webview.loadUrl("http://www.google.com");
}

It's works fine for me
这对我来说很好用
WebView webView = (WebView)findViewById(R.id.webView);
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
webView.loadUrl("http://www.google.com");
Good Luck!
祝你好运！

The quick and dirty solution can be when your android app get started set the background colour according to web view eg i am using black colour so myWebView.setBackgroundColor(Color.parseColor("#000000"));
快速而肮脏的解决方案可能是当您的 android 应用程序开始时根据网络视图设置背景颜色，例如我使用黑色所以 myWebView.setBackgroundColor(Color.parseColor("#000000"));
