[英]Unable to load url in webview - black screen
I have been trying a couple of approaches, some found here, to load a url with webview in my app, all so far unsuccessful with one particular page from a client. 我一直在尝试几种方法,在我的应用程序中使用webview加载URL,但到目前为止,对于客户端的一个特定页面,这些方法均无法成功。 Let's for example take this approach: 让我们以这种方式为例:
Main.xml main.xml中
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/background">
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="@drawable/top_heading"
android:id="@+id/rlayout1">
<TextView android:layout_width="wrap_content"
android:layout_centerVertical="true" android:layout_centerHorizontal="true"
android:textColor="#ffffff" android:textSize="22dip"
android:textStyle="bold" android:layout_height="wrap_content"
android:text="More Information" android:id="@+id/txtviewfbdisplaytitle" />
</RelativeLayout>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_below="@+id/rlayout1"
android:id="@+id/rlayout2">
<WebView android:id="@+id/webview1" android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1.0" />
</RelativeLayout>
</RelativeLayout>
MainActivity.Java MainActivity.Java
public class MainActivity extends Activity {
private class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
Button btnBack;
WebView webview;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview=(WebView)findViewById(R.id.webview1);
webview.setWebViewClient(new MyWebViewClient());
openURL();
}
/** Opens the URL in a browser */
private void openURL() {
webview.loadUrl("[see solution]");
webview.requestFocus();
}
}
While other websites work, this one won't. 当其他网站正常工作时,该网站将无法工作。 I am fairly new to Android programming. 我是Android编程的新手。 What could I try next? 接下来我可以尝试什么?
Side question: What does the url do differently to prevent a successful load? 附带问题:为了防止成功加载,URL有何不同之处?
The website uses DOM Storage to function and since by default DOM storage is disabled in android webview
you have to enable it. 该网站使用DOM存储功能,并且由于默认情况下android webview
禁用了DOM存储,因此您必须启用它。
webview.setWebViewClient(new MyWebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setDomStorageEnabled(true);
openURL();
