保存网页以供离线使用并调用相同的 android

我有一个 Android 应用程序要求，我需要打开保存的网页，如何做同样的事情？首先，我们如何保存一个网页及其对Android的依赖，然后在您的应用程序中打开它？任何输入都会有很大帮助！

首先我们先保存一下网络档案 from webview

private void initUI{
     webView = (WebView) findViewById(R.id.webView);
     AndroidWebClient client = new AndroidWebClient();
     webView.setWebViewClient(client);
     WebSettings webSettings = webView.getSettings();
     webSettings.setJavaScriptEnabled(true);
}
private class AndroidWebClient extends WebViewClient {
        @Override
        public void onPageStarted(WebView view, String url,
                                  android.graphics.Bitmap favicon) {                
        }
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            view.saveWebArchive(Environment.getExternalStorageDirectory()
                    + File.separator +"myArchive"+".mht");
            // our webarchive wull be available now at the above provided location with name "myArchive"+".mht"

        }
        public void onLoadResource(WebView view, String url) {

        }
      }

所有 API 中保存网络存档的方式都是相同的，但加载它的方式有所不同

对于 API 小于 Kitkat

private void loadArchive(){
     String rawData = null;
        try {
            rawData =   getStringFromFile(Environment.getExternalStorageDirectory()
                    + File.separator+"myArchive"+".mht");
        } catch (Exception e) {
            e.printStackTrace();
        }
webView.loadDataWithBaseURL(null, rawData, "application/x-webarchive-xml", "UTF-8", null);
}

  public String getStringFromFile (String filePath) throws Exception {
        File fl = new File(filePath);
        FileInputStream fin = new FileInputStream(fl);
        String ret = convertStreamToString(fin);
        //Make sure you close all streams.
        fin.close();
        return ret;
    }

    public  String convertStreamToString(InputStream is) throws Exception {
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line).append("\n");
        }
        reader.close();
        return sb.toString();
    }

Kitkat 及以上版本

private void loadArchive(){
   webView.loadUrl("file:///"+Environment.getExternalStorageDirectory()
                + File.separator+"myArchive"+".mht");
}
