    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        web = (WebView) findViewById(R.id.web);
       // web.loadUrl("http://wallpaperswide.com/");
        //加载自己写的text网页
//        web.loadData(url,"text/html",null);
        //汉字编码
         //web.loadDataWithBaseURL(null ,url,"text/html","utf_8",null);
        web.loadUrl("file:///android_asset/test.html");
        //加载网站必写的
        web.setWebViewClient(new WebViewClient());

        //进度条加对话框
        progressDialog=new ProgressDialog(this);
        progressDialog.setMessage("进度对话框");
        progressDialog.setTitle("对话框");
        progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        progressDialog.setButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                progressDialog.dismiss();
            }
        });
       // progressDialog.show();

        web.setWebViewClient(new WebViewClient(){
            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
                progressDialog.show();
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                progressDialog.dismiss();
            }
