好用的GsonUtils,Json转任何Bean,Bean转Json字符串

1.需要准备gson包

点击下载gson2.3.1

2.代码如下

import com.google.gson.Gson;
import com.google.gson.JsonArray;
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;

import java.util.ArrayList;
import java.util.List;

public class GsonUtils {

    private static Gson mGson = new Gson();

    public static  T json2Bean(String json, Class clazz) {
        try {
            return mGson.fromJson(json, clazz);
        } catch (Exception e) {
            LogUtils.e(e.toString());
            return null;
        }

    }

    /**
     *
     * @param json
     * @param clazz
     * @param 
     * @return
     */
    public static List toList(String json,Class clazz) {
        ArrayList mList = new ArrayList();
        JsonArray array = new JsonParser().parse(json).getAsJsonArray();
        for(final JsonElement elem : array){
            mList.add(mGson.fromJson(elem, clazz));
        }
        return mList;
    }

    /**
     * fromJson
     * @param json json
     * @param c c
     * @param  
     * @return T
     */
    public static  T fromJson(String json, Class c){
        return mGson.fromJson(json, c);
    }

    /**
     * toJson
     * @param src src
     * @return String
     */
    public static String toJson(Object src) {
        return mGson.toJson(src);
    }
