Android个人所得税计算器

本人所做的android个人所得税计算器程序。

先贴效果图：

1.layout布局主要使用TableLayout，代码如下

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TableLayout android:id="@+id/tlItems" android:layout_width="fill_parent" android:layout_height="wrap_content" > <TableRow> <TextView android:text="税前月入:"/>

2.java实现，计算个税的方法很多，网上都有介绍，目前是按照9级税率的算法实现的，代码如下：
