java与js代码互调示例代码

public class CzingLBWebMain extends DroidGap {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.loadUrl(file:///android_asset/www/czingIndexHome.html);
WebSettings webSettings = this.appView.getSettings();
webSettings.setLoadWithOverviewMode(true);
webSettings.setSavePassword(false);
webSettings.setSaveFormData(false);
webSettings.setSupportZoom(false);
webSettings.setAllowFileAccess(true);
webSettings.setJavaScriptEnabled(true);
webSettings.setPluginState(WebSettings.PluginState.ON);
// 向js中添加一个java实例,以便js代码调用java代码
this.appView.addJavascriptInterface(this, "appDownloader");
}
public void callBackJava(){
}
}

String resUrl="aa";
String resId="bb";
String callBack="javascript:callBackServive('"+resUrl+"','"+resId+"')";//注意传递两个以上参数的方法
this.appView.loadUrl(callBack);
