Java 连接N个字符串

我是新的安卓系统，我需要发送短信，其中将包含以下内容 e、 g:“1”+“\n”+“f_名称”+“l_名称”+“滚动”；我正在arraylist中存储这些信息。有人能建议我如何执行该操作吗？我已经做了一些操作

try {
        SAXParserFactory spf = SAXParserFactory.newInstance();
        SAXParser sp = spf.newSAXParser();
        XMLReader xr = sp.getXMLReader();
        System.out.println("RN-->>created parser");
        SAXXMLHandlerChalanForm ch = new SAXXMLHandlerChalanForm();
        xr.setContentHandler(ch);
        xr.parse(new InputSource(getAssets().open("Chalan.xml")));

        ArrayList<ChalanFormDTO> chalanList = ch.getChalanData();
        System.out.println("size of ChalanList" + chalanList.size());



        for (int i = 0; i < chalanList.size(); i++) {

        if (chalanNum.equalsIgnoreCase(chalanList.get(i).getChalanNo())) 
                   {                             text_chalanNo.setText(chalanList.get(i).getChalanNo());



                text_buyName.setText(chalanList.get(i).getBuyerName());

                text_date.setText(chalanList.get(i).getDates());

                text_sales.setText(chalanList.get(i).getSales());
                System.out.println("Size of LISTOFITEMS:\n"
                        + chalanList.get(i).getListOfStock().size());
                for (int j = 0; j < chalanList.get(i).getListOfStock()
                        .size(); j++) {
                    TableRow tr1 = new TableRow(this);
                    tr1.setLayoutParams(new LayoutParams(
                            LayoutParams.MATCH_PARENT,
                            LayoutParams.WRAP_CONTENT));

                    TextView tv9 = new TextView(this);
                    tv9.setText(String.valueOf(j+1));
                    tv9.setBackgroundResource(R.drawable.border_top);
                    tv9.setTextColor(getResources().getColor(R.color.Black));
                    tv9.setLayoutParams(new TableRow.LayoutParams(dpwidth/2,
                            LayoutParams.WRAP_CONTENT));
                    tv9.setGravity(Gravity.CENTER_HORIZONTAL);
                    tv9.setMinimumWidth(dpwidth);
                    tr1.addView(tv9);


                    TextView tv4 = new TextView(this);
                    tv4.setText(chalanList.get(i).getListOfStock().get(j)
                            .getName());
                    tv4.setBackgroundResource(R.drawable.border_top);
                    tv4.setTextColor(getResources().getColor(R.color.Black));
                    tv4.setLayoutParams(new TableRow.LayoutParams(dpwidth,
                            LayoutParams.WRAP_CONTENT));
                    tv4.setGravity(Gravity.CENTER_HORIZONTAL);
                    tv4.setMinimumWidth(dpwidth);
                    tr1.addView(tv4);

                    TextView tv6 = new TextView(this);
                    tv6.setText(chalanList.get(i).getListOfStock().get(j)
                            .getQuantity());
                    tv6.setBackgroundResource(R.drawable.border_top);
                    tv6.setTextColor(getResources().getColor(R.color.Black));
                    tv6.setLayoutParams(new TableRow.LayoutParams(dpwidth,
                            LayoutParams.WRAP_CONTENT));
                    tv6.setGravity(Gravity.CENTER_HORIZONTAL);
                    tv6.setMinimumWidth(dpwidth);
                    tr1.addView(tv6);
                    table.addView(tr1, 3);

                }

            }

        }

    } catch (Exception e) {
        // TODO: handle exception
    }

试试看{
SAXParserFactory spf=SAXParserFactory.newInstance（）；
SAXParser sp=spf.newSAXParser（）；
XMLReader xr=sp.getXMLReader（）；
System.out.println（“RN-->>创建的解析器”）；
SAXXMLHandlerChalanForm ch=新的SAXXMLHandlerChalanForm（）；
xr.setContentHandler（ch）；
parse（新的InputSource（getAssets（）.open（“Chalan.xml”））；
ArrayList chalanList=ch.getChalanData（）；
System.out.println（“ChalanList的大小”+ChalanList.size（））；
对于（int i=0；i

您可以使用for循环将arraylist数据附加到stringbuffer中

创建一个类似stringbuffer的

StringBuffer strbuf = new StringBuffer();
for(int i = 0; i<chalanList.size; i++)
{
     strbuf.append("1\n");
     strbuf.append("f_name: "+chalanList.get(i).f_name);
     strbuf.append(chalanList.get(i).getChalanNo());
     strbuf.append(chalanList.get(i).getBuyerName());
     . . .
}

StringBuffer strbuf=new StringBuffer（）；
对于（int i=0；这个表达式的原始真实示例：“1”+“\n”+“f_name”+“l_name”+“roll”，我指的是您希望输出的准确程度！根据我的代码：对于外部for循环：“1 12-12-2013 sbs pvt.ltd.内部for循环销售人员：stk1 shree prod 1200 stk2 shree_food 1890”
