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);
    }
}

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";
    }
}

            function look() {
                var ua = navigator.userAgent.toLocaleLowerCase();
                alert(ua);
                //判断是否android
                if (/android/.test(ua)) {
