ANDROID：将输入的数字转换为单词
我们的作业指出，我们编写的程序将输入最多6位数字，并将数字转换为单词。例如：123 = 123。我很无聊！然后我找到了这个网站http://www.rgagnon.com/javadetails/java-0426.html 但我真的不明白如何将其转换为android。
请帮助我......请。
这是我的Main_Activity.xml：
package com.example.torres;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
final EditText numbers = (EditText) findViewById(R.id.editText1);
final EditText results = (EditText) findViewById(R.id.editText2);
Button btnConvert = (Button) findViewById(R.id.button1);
btnConvert.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
String numberz =numbers.getText().toString();
try {
final long number = Long.parseLong(numberz);
String returnz = Words.convert(number);
} catch ( NumberFormatException e) {
//Toast.makeToast("illegal number or empty number" , toast.long)
}
} });
}}
这是我的Words.java
package com.example.torres;
import java.text.DecimalFormat;
public class Words {
private static final String[] tensNames = {
"",
" ten",
" twenty",
" thirty",
" forty",
" fifty",

" eighteen",
" nineteen"
};
private Words() {}
public static String convertLessThanOneThousand(int number) {
String soFar;
if (number % 100 < 20){
soFar = numNames[number % 100];
number /= 100;
}
else {
soFar = numNames[number % 10];
number /= 10;
soFar = tensNames[number % 10] + soFar;
number /= 10;
}
if (number == 0) return soFar;
return numNames[number] + " hundred" + soFar;
}
public static String convert(long number) {
// 0 to 999 999 999 999
if (number == 0) { return "zero"; }
String snumber = Long.toString(number);
// pad with "0"
String mask = "000000000000";
DecimalFormat df = new DecimalFormat(mask);
snumber = df.format(number);
// XXXnnnnnnnnn
int billions = Integer.parseInt(snumber.substring(0,3));
// nnnXXXnnnnnn
int millions = Integer.parseInt(snumber.substring(3,6));
// nnnnnnXXXnnn
int hundredThousands = Integer.parseInt(snumber.substring(6,9));
// nnnnnnnnnXXX
int thousands = Integer.parseInt(snumber.substring(9,12));
String tradBillions;
switch (billions) {
case 0:
tradBillions = "";
break;
case 1 :
tradBillions = convertLessThanOneThousand(billions)
+ " billion ";
break;
default :
tradBillions = convertLessThanOneThousand(billions)
+ " billion ";
}
String result = tradBillions;
String tradMillions;
switch (millions) {
case 0:
tradMillions = "";
break;
case 1 :
tradMillions = convertLessThanOneThousand(millions)
+ " million ";
break;
default :
tradMillions = convertLessThanOneThousand(millions)

}
result = result + tradMillions;
String tradHundredThousands;
switch (hundredThousands) {
case 0:
tradHundredThousands = "";
break;
case 1 :
tradHundredThousands = "one thousand ";
break;
default :
tradHundredThousands = convertLessThanOneThousand(hundredThousands)
+ " thousand ";
}
result = result + tradHundredThousands;
String tradThousand;
tradThousand = convertLessThanOneThousand(thousands);
result = result + tradThousand;
// remove extra spaces!
return result.replaceAll("^\\s+", "").replaceAll("\\b\\s{2,}\\b", " ");}
}
现在唯一的问题是什么都没发生lol

您可以为示例链接中的 EnglishNumberToWords 创建单独的类。
并点击按钮，您只需致电
String return_val_in_english = EnglishNumberToWords.convert(YOUR_NUMBER_TO_CONVERT);
public class EnglishNumberToWords {
private static final String[] tensNames = { "", " ten", " twenty", " thirty", " forty",
" fifty", " sixty", " seventy", " eighty", " ninety" };
private static final String[] numNames = { "", " one", " two", " three", " four", " five",
" six", " seven", " eight", " nine", " ten", " eleven", " twelve", " thirteen",
" fourteen", " fifteen", " sixteen", " seventeen", " eighteen", " nineteen" };
private static String convertLessThanOneThousand(int number)
{
String soFar;
if (number % 100 < 20)
{
soFar = numNames[number % 100];
number /= 100;
} else
{
soFar = numNames[number % 10];
number /= 10;
soFar = tensNames[number % 10] + soFar;
number /= 10;
}
if (number == 0)
return soFar;
return numNames[number] + " hundred" + soFar;
}
public static String convert(long number)
{
// 0 to 999 999 999 999
if (number == 0)
{
return "zero";
}
String snumber = Long.toString(number);
// pad with "0"
String mask = "000000000000";
DecimalFormat df = new DecimalFormat(mask);
snumber = df.format(number);
// XXXnnnnnnnnn
int billions = Integer.parseInt(snumber.substring(0, 3));
// nnnXXXnnnnnn
int millions = Integer.parseInt(snumber.substring(3, 6));
// nnnnnnXXXnnn
int hundredThousands = Integer.parseInt(snumber.substring(6, 9));
// nnnnnnnnnXXX
int thousands = Integer.parseInt(snumber.substring(9, 12));
String tradBillions;
switch (billions)
{
case 0:
tradBillions = "";
break;
case 1:
tradBillions = convertLessThanOneThousand(billions) + " billion ";
break;
default:
tradBillions = convertLessThanOneThousand(billions) + " billion ";
}
String result = tradBillions;
String tradMillions;
switch (millions)
{

}
result = result + tradHundredThousands;
String tradThousand;
tradThousand = convertLessThanOneThousand(thousands);
result = result + tradThousand;
// remove extra spaces!
return result.replaceAll("^\\s+", "").replaceAll("\\b\\s{2,}\\b", " ");

Java类： -
public class NumberToWordsConverter {
public static final String[] units = {"", "One", "Two", "Three", "Four",
"Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve",
"Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen",
"Eighteen", "Nineteen"};
public static final String[] tens = {
"", // 0
"", // 1
"Twenty", // 2
"Thirty", // 3
"Forty", // 4
"Fifty", // 5
"Sixty", // 6
"Seventy", // 7
"Eighty", // 8
"Ninety" // 9
};
public static String convert(final int n) {
if (n < 0) {
return "Minus " + convert(-n);
}
if (n < 20) {
return units[n];
}
if (n < 100) {
return tens[n / 10] + ((n % 10 != 0) ? " " : "") + units[n % 10];
}
if (n < 1000) {
return units[n / 100] + " Hundred" + ((n % 100 != 0) ? " " : "") + convert(n % 100);
}
if (n < 100000) {
return convert(n / 1000) + " Thousand" + ((n % 10000 != 0) ? " " : "") + convert(n % 1000);
}
if (n < 10000000) {
return convert(n / 100000) + " Lakh" + ((n % 100000 != 0) ? " " : "") + convert(n % 100000);
}
return convert(n / 10000000) + " Crore" + ((n % 10000000 != 0) ? " " : "") + convert(n % 10000000);
}
}
在您的主要课程中实施。 您可以使用单独的方法，也可以直接使用，无需单独的方法。
private String numToWords (int n){ //optional
NumberToWordsConverter ntw = new NumberToWordsConverter(); // directly implement this
return ntw.convert(n);
} //optional

以上所有解决方案都可以正常工作，唯一的问题是不适用于所有语言，因为所有国家/地区都不具备将数字转换为单词的相同规则集，因此我们需要为每个国家编写单独的算法，
解决方案
ICU4J是一个国际Unicode组件库，允许使用许多与语言翻译有关的实用程序。
-
第1步，如下所示，将ICU4J添加到您的应用级别gradle中
依赖性{
实施组：“ com.ibm.icu”，名称：“ icu4j”，版本：“ 51.1”
}
-
步骤2 定义此方法
private String convertIntoWords(Double str,String language,String Country) { Locale local = new Locale(language, Country); RuleBasedNumberFormat ruleBasedNumberFormat = new RuleBasedNumberFormat(local, RuleBasedNumberFormat.SPELLOUT); return ruleBasedNumberFormat.format(str); } -
第3步 现在您可以像下面这样调用此方法
double value=165; String english=changeCurrancy(value,"en","US"); //one hundred and sixty-five /*Peruvion*/ String Spanish=changeCurrancy(value,"es","PE"); //ciento sesenta y cinco
您可以根据自己的要求更改语言和国家/地区。
享受

您已经完成了所有工作，只需在像这样的文本字段中显示String returnz
results.setText(returnz);
