我正在尝试连接到一个网站,并使用WebView在Android手机上显示它,但它始终向我显示空白页面。 我正在尝试连接到https://givatram.ort.org.il/
我的代码:
public class MainActivity extends AppCompatActivity {
@SuppressLint({"ClickableViewAccessibility", "SetJavaScriptEnabled"})
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setLoadWithOverviewMode(true);
webview.getSettings().setUseWideViewPort(true);
webview.setWebViewClient(new WebViewClient());
webview.setWebChromeClient(new WebChromeClient());
webview.loadUrl("https://givatram.ort.org.il/");
}
}
XML:

此代码可完美地用于其他网站,但是对于这个特殊的网站,它显示空白页,此网站正常工作
