Android 在文本视图中的新行上显示数据库中的每一行

我已经创建了一个

数据库

，它存储了所有正确的值。我需要将存储在

数据库中的每个
行
显示在一个
文本视图
中的新行上

电流输出

添加到
数据库后
将添加并更新当前值，而不是转到新行

所需输出

数据库
中的每一行在
文本视图

将数据插入数据库
执行
显示数据
我假设您希望在单独的行中显示ArrayList的每一项。
试试这个，希望对你有帮助

TextView conciergeServicesTv = (TextView) findViewById(R.id.activity_get_quote_final_concierge_services_tv);
        if (arrayListConciergeServices.size() != 0) { //ArrayList you are receiving\\
            StringBuilder stringBuilder = new StringBuilder();

            for (int i = 0; i < arrayListConciergeServices.size(); i++) {
                if (i == arrayListConciergeServices.size() - 1) {
                    stringBuilder.append(arrayListConciergeServices.get(i));
                } else {
                    stringBuilder.append(arrayListConciergeServices.get(i)).append("\n");
                }
            }
            conciergeServicesTv.setText(stringBuilder);
        } else {
            conciergeServicesTv.setText("No concierge services selected");
        }

TextView礼宾服务stv=（TextView）findViewById（R.id.activity\u get\u quote\u final\u concierge\u services\u tv）；
如果（arrayListConciergeServices.size（）！=0）{//ArrayList您正在接收\\
StringBuilder StringBuilder=新的StringBuilder（）；
对于（int i=0；i
您是否从数据库中获取ArrayList？@RahulChandrabhan是的。您想在不同的行中显示数组列表的每一项吗？是的，每一项在新行但在相同的文本视图中尝试我的答案并让我知道！
