app加载本地网页

　先交代背景
　主机：Ubuntu16.04LTS
　安装服务：Apache2 http服务，80端口已开启
　网络：无线网卡登录　动态分配内网IP 192.168.1.106

１．本地网页已经写入，放在/var/www/html中，设为默认网页．文件名：index.html．因为不进行具体的解析工作，网页代码不加展示．

２．App源代码以及注释
　１）网络请求属于耗时操作，将其封装入Thread类中.

public class HttpThread extends Thread{
    private String url;
    private WebView web;
    private Handler handler;
    private StringBuffer sb = new StringBuffer();

//    初始化
    public HttpThread(String url,WebView web,Handler handler){
    this.url = url;
    this.web = web;
    this.handler = handler;
    }

//编写主要耗时操作
    @override
    public void run(){
        try{
        URL myUrl = new URL(url);
        HttpURLConnection localCon =(HttpURLConnection)myUrl.openConnection();
        localCon.setRequestMethod("GET");

    //通过Connection对象的open方法拿到输入流，传入InputStreamReader对象中，构建BufferedReader对象
        BufferedReader reader = new BufferedReader( new InputStreamReader( localCon.getInputStream() ) );


        String str = null;
        while( (str=reader.readLine() ) != null){
            sb.append(str);
        }//while

        //发送耗时逻辑
        handler.post(new Runnable){
            @override
            public void run(){
                web.loadData(sb.toString(),"text/html;charset=utf-8",null);
            }
        }//handler
        }catch (MalformedURLException e) {
            // TODO Auto-generated catch block
        } catch (IOException e) {
            e.printStackTrace();
        }
    }//run
}//class

　2)主活动调用即可
　

Public Class MainActivity extends Activity{
    private WebView web;
    private Handler handler;
    private String str = "http://192.168.1.106";

    @override
    protected void onCreate(Bundle saveInstanceState){
        super.onCreate(saveInstanceState);
        setContentView(R.layout.activity_main);
        initiate();

//        **线程必须开启才会生效**，调用start()方法．
        new HttpThread(str,web,handler).start();

    }

    public void initiate(){
    web = (WebView)findViewById(R.id.webview);
    }
}
