我无法使用WebView加载此特定网址(http://sia.bogota.unal.edu.co/academia/),但我可以加载其他网址。 (见下图)
这是我的代码
活动类:
package co.luisfer.webview;
import android.app.Activity;
import android.app.ProgressDialog;
import android.net.http.SslError;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.webkit.SslErrorHandler;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
Activity activity;
private ProgressDialog progDailog;
private WebView webView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
activity = this;
progDailog = ProgressDialog.show(activity, "Loading", "Please wait...", true);
progDailog.setCancelable(false);
webView = (WebView) findViewById(R.id.webview);
webView.setWebViewClient(new MyWebViewClient());
WebSettings settings = webView.getSettings();
settings.setBuiltInZoomControls(false);
settings.setSupportZoom(false);
settings.setJavaScriptCanOpenWindowsAutomatically(true);
settings.setAllowFileAccess(true);
settings.setDomStorageEnabled(true);
webView.loadUrl("http://sia.bogota.unal.edu.co/academia");
}
private class MyWebViewClient extends WebViewClient {
@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
handler.proceed();
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
progDailog.show();
view.loadUrl(url);
return true;
}
@Override
public void onPageFinished(WebView view, final String url) {
progDailog.dismiss();
}
}
}
XML文件:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">
<WebView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/webview"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true" />
</RelativeLayout>
我不知道发生了什么。
你能帮助我吗?
