android知识点1之javascript和anroid之间的互相调用

1.javascript代码 

//javascript方法 android调用的方法
function Test(parm){
		 document.getElementById("result").value=parm;
}


//js调用安卓方法
let parm="0001;0002";
alert(parm);
setTimeout(android.toJump(parm), 1000);

2.android代码

webView.addJavascriptInterface(this, "android");//加上javascript接口    


//android调用javascript代码
@JavascriptInterface
public void toJump(String param) {
        try {
            Toast.makeText(MainActivity.this, param, Toast.LENGTH_LONG).show();
            Intent intent = new Intent(this, NextActivity.class);
            intent.putExtra("param", param);
            startActivity(intent);
        } catch (Exception ex) {
            throw ex;
        }
}
