android 通过webView,简单的通过网页唤起本地界面,如果比较多的话最好不要用原生的webView和js去搭建,用框架去做

NOTE : 

1.--

js和android交互是在 javabrige 线程中的,这个线程的hanlder是主线程的,

也就是说需要主线程new的东西可以在这个线程中new;

2.--

Js文件中不能使用 // 做为注释,否则不读取该js;

 //弹窗提示

function appAlert(msg){

javascript.android.appAlert(msg);

}

3.--

@javascriptInterface 这个就不用说了,直接调用的方法必须加这个,如果target API版本大于17的话

@suppressLint(''SetJavaScriptEnabled")很久之前也用这个

4.--

android接受不了js中的对象,比如

java:

@javascriptInterface

public void input(Object obj){

}

@javascriptInterface

public void input(String name,String pwd){

}

js:

javascript.android.input({

user:user.name,

user:user.pwd

});

这个是接收不了的,即使只有一个obj对象;

webView设置
