如何将解析后的值作为webview URL的字符串传递

Question

你好，我正在解析一个“密钥”，这是一个xml文件的url值，设置如此 单击我想要读取值作为字符串，作为要呈现的URL进入webview。那么如何将“Key”值中的解析值作为webview活动的url传递，以便将其作为字符串读取。提前感谢。

我的网页浏览设置如此

public class Article extends Activity{
private WebView webview;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.articleview);

    Bundle b = getIntent().getExtras();
    String KEY_LINK = b.getString("b");
    String url = getIntent().getStringExtra("key");

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



    webview.loadUrl(url);

    webview.loadUrl(KEY_LINK);



}


}
