我有这样的功能：
public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
if (url.contains("images/srpr/logo11w.png")){
return new WebResourceResponse("text/plain", "utf-8",
new ByteArrayInputStream("".getBytes()));
}
return super.shouldInterceptRequest(view, url);
}
而且工作正常，很好。我想通过当前的webView url添加一项检查，并且仅在特定页面上时才拦截请求。当做出这种陈述时：
public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
if (url.contains("images/srpr/logo11w.png") && webView.getUrl().contains("google.lt")){
return new WebResourceResponse("text/plain", "utf-8",
new ByteArrayInputStream("".getBytes()));
}
return super.shouldInterceptRequest(view, url);
}
应用程序崩溃。有人可以帮我，告诉我我做错了什么吗？

最佳答案
您可以尝试以下方法：
public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
if (url.contains("images/srpr/logo11w.png") && Uri.parse(url).getHost().equals("www.google.com")){
return new WebResourceResponse("text/plain", "utf-8",
new ByteArrayInputStream("".getBytes()));
}
return super.shouldInterceptRequest(view, url);
}
如警告所述，您正在WebViewCoreThread中调用webview方法。这样修改您的代码，
YourActivity.this.runOnUiThread(new Runnable() {
public void run() {
// do all web view operations here
webView.loadUrl(Path);
}
});
