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_width="fill_parent"
android:layout_height="wrap_content"
>
<TableRow>
<TextView android:text="税前月入:"/>
<EditText android:id="@+id/etShuiqianNum"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

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：
public class PersonalTax extends Activity {
private static final String LOG_TAG = "PersonalTax";
private TextView tvYanglaoNum, tvYiliaoNum, tvShiyeNum, tvZhufangNum;
private EditText etShuiqianNum, etShuihouNum, etGeshui;
private EditText etYanglao, etYiliao, etShiye, etZhufang;
private EditText etShebaoBase, etYiliaoBase, etZhufangBase,
etQizhengdianBase;
private Button btnJisuan;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// setTitle("个税通个人 所得税计算器");
// 社保与住房公积金缴费金额
tvYanglaoNum = (TextView) findViewById(R.id.tvYanglaoNum);
tvYiliaoNum = (TextView) findViewById(R.id.tvYiliaoNum);
tvShiyeNum = (TextView) findViewById(R.id.tvShiyeNum);
tvZhufangNum = (TextView) findViewById(R.id.tvZhufangNum);
// 税前税后以及个人 所得税金额
etShuiqianNum = (EditText) findViewById(R.id.etShuiqianNum);
etShuiqianNum.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
// 把输入内容同步显示在社保基数，医疗基数，住房公积金基数中
etShebaoBase.setText(etShuiqianNum.getText());
etYiliaoBase.setText(etShuiqianNum.getText());
etZhufangBase.setText(etShuiqianNum.getText());
}
@Override
public void beforeTextChanged(CharSequence s, int start, intcount,
int after) {

}
@Override
