android和javascript结合的开始

public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       Context cx = Context.enter();//当前线程上下文创建

        // 初始化标准对象function object 等等
        // 这个事必须执行的
        Scriptable scope = cx.initStandardObjects(null);

        // 现在可以执行js脚本了
        Object result = null;
        try {
            result = cx.evaluateString(scope, "obj = {a:1, b:['x','y']}",
                                              "MySource", 1, null);
        }
        catch (JavaScriptException jse) {
            // 异常代码
        }
        //获取全局对象,类似浏览器js里的window
        FlattenedObject global = new FlattenedObject(scope);
        //获取obj对象
        FlattenedObject f = (FlattenedObject) global.getProperty("obj");

        // 打印结果"obj == result" 
        Log.d("javascript"，"obj " + (f.getObject() == result ? "==" : "!=") +
                           " result");

        // 打印结果"f.a == 1"
        Log.d("javascript"，"f.a == " + f.getProperty("a"));

        FlattenedObject b = (FlattenedObject) f.getProperty("b");

        // 打印结果 "f.b[0] == x"
        Log.d("javascript"，"f.b[0] == " + b.getProperty(new Integer(0)));

        // 打印结果 "f.b[1] == y"
        Log.d("javascript"，"f.b[1] == " + b.getProperty(new Integer(1)));

        try {
            //打印结果{a:1, b:["x", "y"]}
           Log.d("javascript"，f.callMethod("toString", new Object[0]));
        } catch (PropertyException e) {
            // ignore
        } catch (NotAFunctionException e) {
            // ignore
        } catch (JavaScriptException e) {
            // ignore
        }

        cx.exit();
}

 

请下载rhino源码包

添加js.rar包到android 工程下

 

简单测试一下
