1.xml

<?xml version="1.0" encoding="utf-8"?>

<WebView xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@+id/webview"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent" />

2.activity

package com.firefly.hybirdapp;

import android.content.Intent;

import android.net.Uri;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.KeyEvent;

import android.webkit.WebSettings;

import android.webkit.WebView;

import android.webkit.WebViewClient;

import android.widget.Toast;

public class HomeActivity extends AppCompatActivity {

    WebView myWebView;

    //    String loadUrl = "file:///android_assets/index.html";本地

    String netUrl = "http://172.16.46.114:14023/index.html/";

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_home);

        myWebView = (WebView) findViewById(R.id.webview);

        myWebView.loadUrl(netUrl);//加载Url

        //设置WebView

        myWebView.setWebViewClient(new WebViewClient() {

            @Override

            public boolean shouldOverrideUrlLoading(WebView view, String url) {

                view.loadUrl(url);

                return true;

            }

        });

        //得到设置类

        WebSettings ws = myWebView.getSettings();

        ws.setJavaScriptEnabled(true);//允许js脚本

        //把js调用的方法写在WebApp

        myWebView.addJavascriptInterface(new MyWebAppInterface(this), "android");

    }

    //按返回键返回上一页

    @Override

    public boolean onKeyDown(int keyCode, KeyEvent event) {

        // Check if the key event was the Back button and if there's history

        if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) {

            myWebView.goBack();

            return true;

        }

        return super.onKeyDown(keyCode, event);

    }

}

3.webApp类

package com.firefly.hybirdapp;

import android.content.Context;

import android.util.Log;

import android.webkit.JavascriptInterface;

/**

public class MyWebAppInterface {

    Context context;

    public MyWebAppInterface(Context context) {

        this.context = context;

    }

    @JavascriptInterface

    public String lookData(String data) {

        Log.e("TAG", data + "hello!!");

        //返回信息给html

        return "hello";

    }

}

4.html

<!DOCTYPE html>

<html>

    <head>

        <meta charset="utf-8">

        <meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />

        <title></title>

        <script src="js/mui.min.js"></script>

        <link href="css/mui.min.css" rel="stylesheet" />

        <script type="text/javascript" charset="utf-8">

            mui.init();

            function look() {

                var ua = navigator.userAgent.toLocaleLowerCase();

                alert(ua);

                //判断是否android

                if (/android/.test(ua)) {

                    //发送消息

                    var msg = window.android.lookData('I am html5');

                    //把接收到的消息写到span里面

                    document.getElementById('span').innerHTML = msg;

                    alert(msg);

                }

            }

        </script>

    </head>

    <body>

        <h1>彭丹</h1>

        <button onclick="look()">点击</button>
