for(int i=0;i<data.getData().getList().size();i++){ if (data.getData().getList().get(i).getUserConfigPrimarykey().getConfigName().equals("messageReminding")){ myInfoBean.setMessage_reminding(data.getData().getList().get(i).getConfigValue()); } if (data.getData().getList().get(i).getUserConfigPrimarykey().getConfigName().equals("messageBell")){ myInfoBean.setMessage_bell(data.getData().getList().get(i).getConfigValue()); } if (data.getData().getList().get(i).getUserConfigPrimarykey().getConfigName().equals("navigation")){ myInfoBean.setNavigation(data.getData().getList().get(i).getConfigValue()); } if (data.getData().getList().get(i).getUserConfigPrimarykey().getConfigName().equals("music")){ myInfoBean.setMusic(data.getData().getList().get(i).getConfigValue()); } }看到if条件框了吗，就是判断list中哪个含有我们要的数据对应的键（参数名，ConfigName），如果找到了就把对应的参数值（ConfigValue）取出来
