Question

我在json数据中有一个参数叫做＆＃34;内容＆＃34;从中我想获取图片网址并动态显示ImageView中的图片。

我已经尝试了Pattern和Matcher类，我正确地获得了第一个网址，但无法为多个图片网址制作逻辑。

内容如下：

"content":"<p style=\"text-align: justify;\">Huawei India has expanded the reach and availability of their online-only Honor smartphone series.<img class=\"aligncenter size-full wp-image-14114\" src=\"http:\/\/imageurl.jpg\"\/><p style=\"text-align: justify;\">Huawei India, along with it, has also confirmed that Honor smartphones will get the Android 6.0 Marshmallow updates with other devices in the upcoming year in the month of February.<\/p><img class=\"aligncenter size-full wp-image-14115\" src=\"http:\/\/second Image url.png\" \/>\n<p style=\"text-align: justify;\">The new update is likely to get Huawei Honor users to be excited, if you are a Honor smartphone user do share your feelings in the comment box below.<\/p>\n"

我得到的第一个图片网址如下：

String imgRegex = "<img[^>]+src\\s*=\\s*['\"]([^'\"]+)['\"][^>]*>";
        Pattern p = Pattern.compile(imgRegex);
        Matcher m = p.matcher(posts.getExcerpt());
        String src = "";
        if (m.find()) {
            src = m.group(1);
            imgPost.setVisibility(View.VISIBLE);
            Log.v("groupCount : ",""+m.groupCount());
            //Toast.makeText(this,"pattern : "+src,Toast.LENGTH_LONG).show();
            Picasso.with(this)
                    .load(""+src)
                    .error(R.drawable.ic_launcher)
                    .into(imgPost);
        }

知道如何使用PatternMatcher类或其他任何内容获取所有图片网址吗？

Answer 1

在我看来，一旦你获得了json字符串HTML中的内容。你可以使用JSoup来提取数据非常容易。

Answer 2

您可以使用while( m.find()){ ... }代替条件

解析来自jsonstring的图片网址
