问题描述
我的问题是网页未加载到WebView中.
My problem is that the webpage is not loaded inside the WebView.
mWebview.loadUrl("http://www.google.com");
启动网络浏览器...
mWebview.loadUrl("http://www.google.com");
launches the web browser...
这是我的活动代码:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class Main extends Activity {
private WebView mWebview;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.loadUrl("http://www.google.com");
setContentView(mWebview);
}
}
我在清单中添加了所需的权限:
I added the required permission in the Manifest:
<uses-permission android:name="android.permission.INTERNET" />

Thanks to this post, I finally found the solution. Here is the code:
import android.app.Activity;

import android.webkit.WebResourceError;
import android.webkit.WebResourceRequest;

import android.annotation.TargetApi;
public class Main extends Activity {
private WebView mWebview ;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
@SuppressWarnings("deprecation")
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
@TargetApi(android.os.Build.VERSION_CODES.M)
@Override
public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
// Redirect to deprecated method, so you can use it in all SDK versions
onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
}
});
mWebview .loadUrl("http://www.google.com");
setContentView(mWebview );
}
}
