webkit下DownloadListener
看官方的API很简单,它是webkit下的一个接口,该接口就一个抽象方法:onDownloadStart:
public abstract void onDownloadStart (String url, String userAgent, String contentDisposition, String mimetype, long contentLength)
Notify the host application that a file should be downloaded
Parameters
url | The full url to the content that should be downloaded |
---|---|
userAgent | the user agent to be used for the download. |
contentDisposition | Content-disposition http header, if present. |
mimetype | The mimetype of the content reported by the server |
contentLength | The file size reported by the server |
不用多解释。
下面是它的源码,也非常简单:
