我需要加载一个内部有一些 AJAX 服务调用的 HTML 文件。我需要从 Java 代码调用该 HTML 文件中的函数。我可以在 web 中看到数据加载，但在 Emulator 中看不到。
我的 HTML 文件在下面

</div>
在该代码中，我需要调用 getData() 从 Java 代码传递 3 个参数。
我的Java代码如下：
webView.addJavascriptInterface(new JavaScriptInterface(this), "Android");
String loc = "file:///android_asset/candlechart/candlebar.html";
webView.getSettings().setJavaScriptEnabled(true);
webView.clearView();
// myWebView.measure(100, 100);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.loadUrl(loc);
webView.loadUrl("javascript:getData('1020','M','bar')");
webView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String loc) {
}
});
