 Crosswalk+Cordova開發安卓app之 JavaScript調用java (附原始碼下載)


  1. 定義js回調介面

    /** * js回調介面 *  * @author graceup *  */public class JsInterface {public JsInterface() {}@JavascriptInterfacepublic String sayHello() {// TODO do more thingreturn "Hello World!";}}

           備忘:這裡的 @JavaScriptInterface 所在的包是 import org.xwalk.core.JavascriptInterface;

  2. XWalkView設定JavaScript可用且綁定對象     

    setContentView(R.layout.activity_main);mXWalkView = (XWalkView) findViewById(R.id.activity_main);//綁定mXWalkView.addJavascriptInterface(new JsInterface(), "NativeInterface");mXWalkView.load("file:///android_asset/www/index.html", null);

  3. 調用html執行JavaScript或直接執行Javascript調用Java

    mXWalkView.load("file:///android_asset/www/index.html", null);

    index.html源碼:

    <button onclick="clicked()">button</button><script>function clicked() {  alert(NativeInterface.sayHello());}</script>
