Question

我有一个带有一些自定义选项的Webview，如下所示：

public void WebViewLoad (View view) {
        WebView myWebView = (WebView) findViewById(R.id.webView2);
        myWebView.setFocusable(true);
        myWebView.setFocusableInTouchMode(true);
        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
        myWebView.getSettings().setDomStorageEnabled(true);
        myWebView.getSettings().setDatabaseEnabled(true);
        myWebView.getSettings().setAppCacheEnabled(true);
        myWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

        myWebView.setWebViewClient(new WebViewClient());
        myWebView.setVisibility(View.VISIBLE);
        backtoLanguage.setVisibility(View.VISIBLE);
        myWebView.loadUrl(link); //<-- Load defined URL as link
    }

它的隐藏式直到WebViewLoad被调用，但我想用link从

运行它

public void gotoEnglish() {
SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(this);
            SharedPreferences.Editor editor = sharedPref.edit();
            editor.putInt("selectedlanguage", LanguageFactory.LANGUAGE_ENGLISH);
            editor.commit();
//load WebWiewLoad with URL defined here

}

代码中可能存在一些错误，我对此很陌生......

非常感谢你。

            English();
        } else English();
    }

    public void English() {
        myWebView.loadUrl("http://www.example.com/");
    }

我已经按照你们的要求包含了大部分代码。

Answer 1

将对象myWebView声明为全局变量。然后您可以在gotoEnglish()方法中轻松访问它以加载URL

以下是示例代码

WebView myWebView
public void WebViewLoad (View view) {
    myWebView = (WebView) findViewById(R.id.webView2);
    ...
}

public void gotoEnglish() {
     ...
     myWebView.loadUrl(link); //<-- Load defined URL as link
}

希望这个帮助

Answer 2

我已经使用这种方式存档：

private void go(String strUrl) {
    myWebView.loadUrl(strUrl);
}


public void English() {
        go("http://www.example.com/");
}

将URL传递给WebView并导航到该页面
