【Android 应用】gson数据解析实例

最近老是碰到json数据解析，记录个实例以后方便参考。网上参考的例子基本没有很全的json数据描述，记录三个个实例更直观的参考。

实例1：简单json

解析下面json数据：

{
    ret : 0,
    sources : [
        {
            "name":"爱奇艺",
            "source":"iqiyi",
            "logo":"http://192.168.15.165:80/oms-pic/webSource/aiqiyi.png",
            "payInfo":"0","webPage":"https://v.qq.com/x/cover/io51j0gxgd2f5k3.html"
        }
    ],
    retInfo :"成功",
}

对应class：

public class WebH5UrlBean {
    /**
     * ret : 0
     * sources : [{"name":"爱奇艺","source":"iqiyi","logo":"http://192.168.15.165:80/oms-pic/webSource/aiqiyi.png","payInfo":"0","webPage":"https://v.qq.com/x/cover/io51j0gxgd2f5k3.html"}]
     * retInfo :
     */

    private String ret;
    private String retInfo;
    private List sources;

    public String getRet() {
        return ret;
    }

    public void setRet(String ret) {
        this.ret = ret;
    }

    public String getRetInfo() {
        return retInfo;
    }

    public void setRetInfo(String retInfo) {
        this.retInfo = retInfo;
    }

    public List getSources() {
        return sources;
    }

    public void setSources(List sources) {
        this.sources = sources;
    }

    public static class SourcesBean {
        /**
         * name : 爱奇艺
         * source : iqiyi
         * logo : http://192.168.15.165:80/oms-pic/webSource/aiqiyi.png
         * payInfo : 0
         * webPage : https://v.qq.com/x/cover/io51j0gxgd2f5k3.html
         */

        private String name;
        private String source;
        private String logo;
        private String payInfo;
        private String webPage;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getSource() {
            return source;
        }

        public void setSource(String source) {
            this.source = source;
        }

        public String getLogo() {
            return logo;
        }

        public void setLogo(String logo) {
            this.logo = logo;
        }

        public String getPayInfo() {
            return payInfo;
        }

        public void setPayInfo(String payInfo) {
            this.payInfo = payInfo;
        }

        public String getWebPage() {
            return webPage;
        }

        public void setWebPage(String webPage) {
            this.webPage = webPage;
        }
    }
}

解析代码：

try {
    LogUtil.d(TAG, "getWebUrl response:" + response);
    String[] playUrls = {};
    int type = 0;
    Gson gson = new Gson();
    WebH5UrlBean paramInfo = gson.fromJson(response, WebH5UrlBean.class);
    if (paramInfo != null && paramInfo.getRet().equals("0")) {

        if (paramInfo.getSources() != null && paramInfo.getSources().size() > 0) {
            playUrls = new String[paramInfo.getSources().size()];
            for (int i = 0; i < paramInfo.getSources().size(); i++) {
                playUrls[i] = paramInfo.getSources().get(i).getWebPage();
            }
        } else {
            type = -1;
        }
    } else {
        type = -1;
    }

    VOSSDKListener listener = (VOSSDKListener) vossdkListener;
    listener.onWebUrlResponse(type, playUrls);
} catch (Exception e) {
    e.printStackTrace();
}
