我的问题是该网页未加载到webview中。
mWebview.loadUrl("http://www.google.com"); 启动网络浏览器…
mWebview.loadUrl("http://www.google.com");
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:
<uses-permission android:name="android.permission.INTERNET" />
由于这篇文章,我终于找到了解决方案。这是代码:
import android.app.Activity; import android.os.Bundle; import android.webkit.WebResourceError; import android.webkit.WebResourceRequest; import android.webkit.WebView; import android.webkit.WebViewClient; import android.widget.Toast; 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 ); } }
