Question

我是JSON概念的新手

在下面的代码中，＆＃34; AgentId＆＃34;的值和＆＃34;键入＆＃34;正在改变基于代理商，但我

持续如下

jsonReq.put("agentsId", 7); and 

jsonReq.put("types", 0);

所以我不得不经常改变它们。怎么弄它请帮帮我

    tableLayout.setVisibility(View.VISIBLE);

    ((TextView) findViewById(R.id.bch_name)).setText(Utilities
            .getString(info.getBranchName()));

    ((TextView) findViewById(R.id.busi_Amt)).setText(Utilities
            .getDecimalFormat(info.getBusinessAmt()));

}

}

任何帮助都会给我一个建议 谢谢。
