以脱机模式加载网站

Question

我想在未连接互联网时从缓存加载网站.以下是我在onCreate中设置webview的方法:

    browse.getSettings().setJavaScriptEnabled(true);
    browse.getSettings().setPluginsEnabled(true);
    browse.getSettings().setLoadWithOverviewMode(true);
    browse.getSettings().setUseWideViewPort(true);
    browse.getSettings().setBuiltInZoomControls(true);
    browse.getSettings().setSupportZoom(true);
    browse.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
    browse.setScrollbarFadingEnabled(true);
    browse.getSettings().setLoadsImagesAutomatically(true);
    browse.getSettings().setAppCacheMaxSize(1024 * 1024 * 100);
    browse.getSettings().setAppCacheEnabled(true);

    if (cm.getActiveNetworkInfo().isConnected())
        browse.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
    else
        browse.getSettings().setCacheMode(
                WebSettings.LOAD_CACHE_ELSE_NETWORK);

    browse.setWebViewClient(new WebViewClient() {

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
            t.setVisibility(TextView.VISIBLE);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            t.setVisibility(TextView.GONE);
        }
    });

    try {
        browse.loadUrl(address);
    } catch (Exception e) {
        e.printStackTrace();
    }

这是我正在关注的教程,即使浏览器重新启动,我也在尝试加载以前访问过的网页.不行!请帮我.

PS:我在SO上搜索了所有相关代码,但没有一个有效.
