android Gson ArrayList 将jsonString转成泛型bean ArrayList

build.gradle中添加 
compile 'com.google.code.gson:gson:2.7'
/**
 * 将jsonString转成泛型bean
 * Created by gb on 2018/1/22.
 */
public class GsonUtils {
    /**
     * 将jsonString转成泛型bean
     *
     * @param gsonString
     * @param cls
     * @return
     */
    public static <T> T jsonToBean(String gsonString, Class<T> cls) {
        LogUtils.d("GsonUtils.jsonToBea=" + gsonString);
        T t = null;
        try {
            t = new Gson().fromJson(gsonString, cls);
        } catch (Exception e) {
            LogUtils.d(e.toString());
        }
        return t;
    }
}
如果json字符串是数组，则

Type founderListType = new TypeToken<ArrayList<HomeCategoryBean>>() {}.getType();
List<HomeCategoryBean> listTemp = new Gson().fromJson(json, founderListType);
