这里有一个输入错误WwbView…WebView也需要一个变量，它的代码行不正确

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

---

它仍然无法工作，我还有一些错误，如：错误：找不到符号类webChromeClientCheck您的导入、清理和重建。。。导入android.webkit.WebView；导入android.webkit.WebViewClient；我已经导入了这些android网络工具包，但它仍然无法解析符号。我更新了日志，首先类名不是以小写字母开头的…所以它应该是新的WebChromeClient，并且没有声明webView变量…您定义了webView，然后使用webView。只有打字错误和愚蠢的错误。

        WebView WebView= (WebView) findViewById(R.id.webView);
        webView.loadUrl("file:///android_asset/myHtml.html");
                webView.getSettings().setJavaScriptEnabled(true)

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

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