android webview =找不到网页=在哪里添加onReceivedError

Question

I ma newbie, please guide me where to add the onReceivedError code.

This is my original code:

My static page directs to my website, if the internet is slow or no network connect, I get a error showing url, I would like to show another html error page, if possible even reload button.

Thanks in advance for guidance.

    public class WebActivity extends Activity {

    private WebView webView;

    public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.webcontent);

    webView = (WebView) findViewById(R.id.webView);

    webView.getSettings().setJavaScriptEnabled(true);

    webView.setWebViewClient(new WebViewClient());    //the lines of code added
    webView.setWebChromeClient(new WebChromeClient()); //same as above

    webView.loadUrl("file:///android_asset/index.html");

    }

            @Override
            public void onBackPressed() {
                    if (webView.canGoBack()) {
                            webView.goBack();
                    } else {
                            super.onBackPressed();
                    }
            }

Where to place the below code: please guide Or any improvements

            @Override
            public void onReceivedError(WebView WebResourceRequest WebResourceError) {
            webView.loadUrl("file:///android_asset/errorpage.html");

Answer 1

It is set in new WebViewClient() :

 webView.setWebViewClient(new WebViewClient() {
    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            webView.loadUrl("file:///android_asset/errorpage.html");
            super.onReceivedError(view, errorCode, description, failingUrl);
    }
 });

Now when an error is received, the web view will load that error page.
