Javascript函数未在Android WebView中调用

我正在制作一个可在android webview中运行的应用程序。我面临一个奇怪的问题，我的JavaScript函数没有在<a></a>onClick方法上调用。

这是我的html和JavaScript代码：

<html>

<script type="text/javascript" src="http://blue.xxxxxxxx.com/xxxxx/site/js/jquery.js"></script>
<script>
function openFileDialog()
{
    //$("#file").click();   
    alert("Test");
}
</script>
<body>

<form action="upload_file.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>


<a href="javascript:;" onclick="openFileDialog();">Shujaat</a>
</body>
</html>

这是我的整个Java Webviews代码。

package com.example.findozerapp;

import my.functions.MyFunctions;
import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.webkit.WebSettings.ZoomDensity;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends Activity {
Context context = MainActivity.this;
Activity activity = MainActivity.this;

WebView webView;
MyFunctions myFunctions;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    myFunctions = new MyFunctions(activity);
    webView = (WebView) findViewById(R.id.webView1);

    configureWebview();

}

@Override
protected void onStart() {
    // TODO Auto-generated method stub
    super.onStart();

    webView.loadUrl("http://www.xxxxxxx.com/qadir/");

}

private void configureWebview() {

    webView.setPadding(0, 0, 0, 0);
    webView.setInitialScale(myFunctions.setWebViewScale());
    webView.getSettings().setDefaultZoom(ZoomDensity.FAR);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    webView.getSettings().setBuiltInZoomControls(true);
    webView.getSettings().setLoadWithOverviewMode(true);
    webView.getSettings().setUseWideViewPort(true);
    webView.getSettings().setCacheMode(MODE_APPEND);

    webView.setWebViewClient(new MyWebViewClient());

}

private class MyWebViewClient extends WebViewClient {

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        // TODO Auto-generated method stub
        super.onPageStarted(view, url, favicon);
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // TODO Auto-generated method stub
        return super.shouldOverrideUrlLoading(view, url);
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        // TODO Auto-generated method stub
        super.onPageFinished(view, url);
    }
}

 }
