How can I change the previous web page to my own if it did not load in WEB VIEW?
问题
以下是您要翻译的内容：
问题在于当加载新页面时，WEBVIEW会显示先前的页面。如果页面根本没有加载或加载出现错误，则会显示“网页不可用”的消息，我不希望看到这个消息，而是想要隐藏它或替换为自己的消息。如何实现这一点？

The problem is that when a new page is loaded, WEBVIEW shows the previous one, and if it is not loaded at all or loaded with errors, then it shows the message The web page is not available, which I would not want to see at all, but hide or replace it with my own, how is this possible to implement?

你可以在onReceivedError函数中调用loadErrorPage(view)函数。
以下代码将加载您需要显示的错误内容。在这里，我使用loadDataWithBaseURL加载HTML文件。
public void loadErrorPage(WebView webview){
if(webview!=null){
String htmlData = "<html><body><div align=\"center\">This is the description for the load fail : "
+ description + "\nThe failed url is : " + failingUrl + "\n</div></body></html>";
webview.loadUrl("about:blank");
webview.loadDataWithBaseURL(null,htmlData, "text/html", "UTF-8",null);
webview.invalidate();
}
}
您可以按以下方式编写onReceivedError：
WebView wv = (WebView) findViewById(R.id.webView);
wv.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
super.onReceivedError(view, errorCode, description, failingUrl);
// 在这里调用loadErrorPage函数
}
});
英文:
You can call loadErrorPage(view) function in the onReceivedError function.
The following code will load the error content you need to show.Here i am load the html file with loadDataWithBaseURL.
public void loadErrorPage(WebView webview){
if(webview!=null){
String htmlData ="<html><body><div align=\"center\" >"This is
the description for the load fail : "+description+"\nThe failed url is
: "+failingUrl+"\n"</div></body>";
webview.loadUrl("about:blank");
webview.loadDataWithBaseURL(null,htmlData, "text/html", "UTF-8",null);
webview.invalidate();
}
}
You can write onReceivedError like that :
WebView wv = (WebView) findViewById(R.id.webView);
wv.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
suåper.onReceivedError(view, errorCode, description, failingUrl);
//call loadErrorPage function here
}
});
