android webview不能直接下載檔案

• 所以要實現下載檔案要呼叫內建瀏覽器如下

private class MWebViewDownLoadListener implements DownloadListener {
        @Override
        public void onDownloadStart(String url, String userAgent,       String contentDisposition, String mimetype, long contentLength) {
            Uri uri = Uri.parse(url);
            Intent intent = new
 
 Intent(Intent.ACTION_VIEW, uri);
            startActivity(intent);
        }
    }
   webview.setDownloadListener(new MWebViewDownLoadListener());

• 這樣就可以了
