我正在开发一个应用程序，我仍然是eclipse和android的新手。我正在从excel制作一个关于PMT功能的应用程序。现在我只能显示像
这样的结果First Payment : Monthly Payment
"some calculated result" "some calculated result"
现在，我正在使用警报消息或Toast文本来显示它。我希望它显示在新活动的表格上，但我不知道如何实现它。
这是我计算付款并显示付款的代码（使用按钮）：

一些解释： tumbal1，tumbal2，tumbal3 .....等等//将双倍结果转换为long tumbala1，tumbala2，tumbala3 ....等等//计算第一笔付款 tumbalaa1，tumabalaa2，tumbalaa3 .....等等//将double转换为long 我使用很长时间，因为输入可能超过12位
public void mulaihitung = public void startcalculating（english翻译）
mulaihitung是一个onClick on layout.xml，例如<button android:OnClick="mulaihitung"/> ,
ethint是一个输入价格的编辑文本，
etpersen是一个输入价格百分比的编辑文本。
new AlertDialog.Builder(this)
是警告对话框，其中包含选项yes和no，所有结果都将显示在那里。
将在alertdialog上显示的结果来自这一行
.setMessage("Total Pembayaran Pertama : " + tumbalaa1 + " IDR" +newline +" Cicilan 1 tahun : " + tumbal1 + " IDR" + newline + "Total Pembayaran Pertama : "
+ tumbalaa2 + " IDR" +newline + " Cicilan 2 tahun : "+tumbal2 +" IDR"+ newline + "Total Pembayaran Pertama : " + tumbalaa3 + " IDR" + newline +" Cicilan 3 tahun : "+ tumbal3 +" IDR"+ newline +
"Total Pembayaran Pertama : " + tumbalaa4 + " IDR" +newline + " Cicilan 4 tahun : "+ tumbal4 +" IDR"+ newline + "Total Pembayaran Pertama : " + tumbalaa5 + " IDR" +newline + " Cicilan 5 tahun : "+ tumbal5 +" IDR");
当我们点击/单击按钮时会出现alertdialog，它看起来像这样:(示例）
Total Pembayaran Pertama 1000000 IDR
Cicilan 1 tahun 10000 IDR
Total Pembayaran Pertama 900000 IDR
Cicilan 2 tahun 9000 IDR
Total Pembayaran Pertama 800000 IDR
Cicilan 3 tahun 8000 IDR
Total Pembayaran Pertama 700000 IDR
Cicilan 4 tahun 7000 IDR
Total Pembayaran Pertama 600000 IDR
Cicilan 5 tahun 6000 IDR
Total Pembayaran Pertama =第一笔付款（英文翻译），这来自tumbalaa＃calculation。 Cicilan＃tahun =＃year（s）的每月付款（英文翻译），这来自于tumbal＃calculation
