推荐答案
我还没有实际使用此发挥各地还没有，但是从文件看来你至少有两个（非德precated）选项：
I haven't actually played around with this yet, but from the docs it appears you have at least two (non-deprecated) options:
根据文档，你可以使用第一个选项，以测试 IMAGE_TYPE 的结果，和URL的图像提供，以及：
According to the documentation you can use the first option to test for IMAGE_TYPE as result, and a url to the image is provided as well:
如果找到了HTML :: img标签，该HitTestResult类型设置为
IMAGE_TYPE和URL设置中的额外字段。
If a HTML::img tag is found, the HitTestResult type is set to IMAGE_TYPE and the url is set in the "extra" field.
第二个选项会给你一个类似的结果：
The second option will give you a similar result:
请求图像的URL最后由用户触摸。味精会
发送到其目标以字符串重新presenting URL作为它的对象。
Request the url of the image last touched by the user. msg will be sent to its target with a String representing the url as its object.
不知道如果这些选项都以长按太虽然兼容。
Not sure if these options are compatible with a 'long click' too though.
另外，你怎么心里有链接点击一个按钮到一个特定的形象？根据您的这个解决方案，您还可以简单地使用捕获所有加载图片资源<一个href=\"http://developer.android.com/reference/android/webkit/WebViewClient.html#onLoadResource%28android.webkit.WebView,%20java.lang.String%29\"相对=nofollow> onLoadResource（的WebView视图，字符串URL） ，建立图像引用的列表，并下载按钮，点击是指太之一。
Alternatively, how did you have in mind to link clicking a button to a specific image? Depending on your solution for this, you may also be able to simply capture all loaded image resources using onLoadResource(WebView view, String url), build a list of image references and download the one that button click refers too.
