Android 设置货币输入文本格式的更好方法？,android,Android,我有一个editText，起始值是$0.00。按1时，它将更改为$0.01。按4，它会涨到0.14美元。按8，1.48美元。按backspace，$0.14等如果是这样的话，问题是，如果有人手动定位光标，格式就会出现问题。如果他们删除小数点，它就不会回来了。如果他们将光标放在小数点前面并键入2，它将显示$02.00而不是$2.00。例如，如果他们试图删除$，它将删除一个数字这是我正在使用的代码，如果有任何建议，我将不胜感激 mEditPrice.setRawInputType(Configu

我有一个editText，起始值是$0.00。按1时，它将更改为$0.01。按4，它会涨到0.14美元。按8，1.48美元。按backspace，$0.14等

如果是这样的话，问题是，如果有人手动定位光标，格式就会出现问题。如果他们删除小数点，它就不会回来了。如果他们将光标放在小数点前面并键入2，它将显示$02.00而不是$2.00。例如，如果他们试图删除$，它将删除一个数字

这是我正在使用的代码，如果有任何建议，我将不胜感激

mEditPrice.setRawInputType(Configuration.KEYBOARD_12KEY);
    public void priceClick(View view) {
    mEditPrice.addTextChangedListener(new TextWatcher(){
        DecimalFormat dec = new DecimalFormat("0.00");
        @Override
        public void afterTextChanged(Editable arg0) {
        }
        @Override
        public void beforeTextChanged(CharSequence s, int start,
                int count, int after) {
        }
        @Override
        public void onTextChanged(CharSequence s, int start,
                int before, int count) {
            if(!s.toString().matches("^\\$(\\d{1,3}(\\,\\d{3})*|(\\d+))(\\.\\d{2})?$"))
            {
                String userInput= ""+s.toString().replaceAll("[^\\d]", "");
                if (userInput.length() > 0) {
                    Float in=Float.parseFloat(userInput);
                    float percen = in/100;
                    mEditPrice.setText("$"+dec.format(percen));
                    mEditPrice.setSelection(mEditPrice.getText().length());
                }
            }
        }
    });

我测试了你的方法，但当我使用大量数字时，它失败了。。。我创造了这个：

private String current = "";
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
    if(!s.toString().equals(current)){
       [your_edittext].removeTextChangedListener(this);

       String cleanString = s.toString().replaceAll("[$,.]", "");
                
       double parsed = Double.parseDouble(cleanString);
       String formatted = NumberFormat.getCurrencyInstance().format((parsed/100));
                    
       current = formatted;
       [your_edittext].setText(formatted);
       [your_edittext].setSelection(formatted.length());
       
       [your_edittext].addTextChangedListener(this);
    }
}

Kotlin变体：

private var current: String = ""

         override fun onTextChanged(
            s: CharSequence,
            start: Int,
            before: Int,
            count: Int
        ) {
            if (s.toString() != current) {
                discount_amount_edit_text.removeTextChangedListener(this)

                val cleanString: String = s.replace("""[$,.]""".toRegex(), "")

                val parsed = cleanString.toDouble()
                val formatted = NumberFormat.getCurrencyInstance().format((parsed / 100))

                current = formatted
                discount_amount_edit_text.setText(formatted)
                discount_amount_edit_text.setSelection(formatted.length)

                discount_amount_edit_text.addTextChangedListener(this)
            }
        }

实际上，以前提供的解决方案不起作用。如果要输入100.00，则该选项无效

替换：

double parsed = Double.parseDouble(cleanString);
String formato = NumberFormat.getCurrencyInstance().format((parsed/100));

与：

我必须说我对代码做了一些修改。问题是你应该使用BigDecimal的

对我来说，它是这样工作的

 public void onTextChanged(CharSequence s, int start,
                    int before, int count) {
                if(!s.toString().matches("^\\$(\\d{1,3}(\\,\\d{3})*|(\\d+))(\\.\\d{2})?$"))
                {
                    String userInput= ""+s.toString().replaceAll("[^\\d]", "");
                    if (userInput.length() > 2) {
                        Float in=Float.parseFloat(userInput);
                        price = Math.round(in); // just to get an Integer
                        //float percen = in/100;
                        String first, last;
                        first = userInput.substring(0, userInput.length()-2);
                        last = userInput.substring(userInput.length()-2);
                        edEx1.setText("$"+first+"."+last);
                        Log.e(MainActivity.class.toString(), "first: "+first + " last:"+last);
                        edEx1.setSelection(edEx1.getText().length());
                    }
                }
            }

最好使用InputFilter接口。使用正则表达式处理任何类型的输入都要容易得多。我的货币输入格式解决方案：

public class CurrencyFormatInputFilter implements InputFilter {

Pattern mPattern = Pattern.compile("(0|[1-9]+[0-9]*)(\\.[0-9]{1,2})?");

@Override
public CharSequence filter(
        CharSequence source,
        int start,
        int end,
        Spanned dest,
        int dstart,
        int dend) {

String result = 
        dest.subSequence(0, dstart)
        + source.toString() 
        + dest.subSequence(dend, dest.length());

Matcher matcher = mPattern.matcher(result);

if (!matcher.matches()) return dest.subSequence(dstart, dend);

return null;
}
}

有效期：0.00,0.0,10.00,111.1
无效：0,0.000,111,1010.00,01.0

如何使用：

editText.setFilters(new InputFilter[] {new CurrencyFormatInputFilter()});

好的，这里有一个更好的方法来处理货币格式，删除向后击键。该代码基于上面的@AndroidGuillive'代码。。。但是，处理一些与向后删除和一些解析异常相关的问题： [更新]以前的解决方案存在一些问题。。。这是一个更好的解决方案：而且。。。详情如下:

这种方法更好，因为它使用传统的Android机制。其思想是在用户存在视图后格式化值

定义一个InputFilter来限制数值–这在大多数情况下是必需的，因为屏幕不够大，无法容纳长文本视图。这可以是静态内部类，也可以只是另一个普通类：

/** Numeric range Filter. */
class NumericRangeFilter implements InputFilter {
    /** Maximum value. */
    private final double maximum;
    /** Minimum value. */
    private final double minimum;
    /** Creates a new filter between 0.00 and 999,999.99. */
    NumericRangeFilter() {
        this(0.00, 999999.99);
    }
    /** Creates a new filter.
     * @param p_min Minimum value.
     * @param p_max Maximum value. 
     */
    NumericRangeFilter(double p_min, double p_max) {
        maximum = p_max;
        minimum = p_min;
    }
    @Override
    public CharSequence filter(
            CharSequence p_source, int p_start,
            int p_end, Spanned p_dest, int p_dstart, int p_dend
    ) {
        try {
            String v_valueStr = p_dest.toString().concat(p_source.toString());
            double v_value = Double.parseDouble(v_valueStr);
            if (v_value<=maximum && v_value>=minimum) {
                // Returning null will make the EditText to accept more values.
                return null;
            }
        } catch (NumberFormatException p_ex) {
            // do nothing
        }
        // Value is out of range - return empty string.
        return "";
    }
}

此类将在编辑时删除货币格式-依赖于标准机制。当用户退出时，将重新应用货币格式

最好定义一些静态变量以最小化实例数：

   static final InputFilter[] FILTERS = new InputFilter[] {new NumericRangeFilter()};
   static final View.OnFocusChangeListener ON_FOCUS = new AmountOnFocusChangeListener();

最后，在onCreateView（…）中：

您可以重用过滤器，并关注任意数量的EditText视图

以下是Utils类：

public class Utils {

   private static final NumberFormat FORMAT_CURRENCY = NumberFormat.getCurrencyInstance();
   /** Parses an amount into cents.
    * @param p_value Amount formatted using the default currency. 
    * @return Value as cents.
    */
   public static int parseAmountToCents(String p_value) {
       try {
           Number v_value = FORMAT_CURRENCY.parse(p_value);
           BigDecimal v_bigDec = new BigDecimal(v_value.doubleValue());
           v_bigDec = v_bigDec.setScale(2, BigDecimal.ROUND_HALF_UP);
           return v_bigDec.movePointRight(2).intValue();
       } catch (ParseException p_ex) {
           try {
               // p_value doesn't have a currency format.
               BigDecimal v_bigDec = new BigDecimal(p_value);
               v_bigDec = v_bigDec.setScale(2, BigDecimal.ROUND_HALF_UP);
               return v_bigDec.movePointRight(2).intValue();
           } catch (NumberFormatException p_ex1) {
               return -1;
           }
       }
   }
   /** Formats cents into a valid amount using the default currency.
    * @param p_value Value as cents 
    * @return Amount formatted using a currency.
    */
   public static String formatCentsToAmount(int p_value) {
       BigDecimal v_bigDec = new BigDecimal(p_value);
       v_bigDec = v_bigDec.setScale(2, BigDecimal.ROUND_HALF_UP);
       v_bigDec = v_bigDec.movePointLeft(2);
       String v_currency = FORMAT_CURRENCY.format(v_bigDec.doubleValue());
       return v_currency.replace(FORMAT_CURRENCY.getCurrency().getSymbol(), "").replace(",", "");
   }
   /** Formats cents into a valid amount using the default currency.
    * @param p_value Value as cents 
    * @return Amount formatted using a currency.
    */
   public static String formatCentsToCurrency(int p_value) {
       BigDecimal v_bigDec = new BigDecimal(p_value);
       v_bigDec = v_bigDec.setScale(2, BigDecimal.ROUND_HALF_UP);
       v_bigDec = v_bigDec.movePointLeft(2);
       return FORMAT_CURRENCY.format(v_bigDec.doubleValue());
   }

}

我建立在Guilhermes answer的基础上，但我保留了光标的位置，并以不同的方式对待句点-这样，如果用户在句点之后键入，它不会影响句点之前的数字，我发现这提供了一个非常平滑的输入

    [yourtextfield].addTextChangedListener(new TextWatcher()
    {
        NumberFormat currencyFormat = NumberFormat.getCurrencyInstance();
        private String current = "";

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count)
        {
            if(!s.toString().equals(current))
            {
                   [yourtextfield].removeTextChangedListener(this);

                   int selection = [yourtextfield].getSelectionStart();


                   // We strip off the currency symbol
                   String replaceable = String.format("[%s,\\s]", NumberFormat.getCurrencyInstance().getCurrency().getSymbol());
                   String cleanString = s.toString().replaceAll(replaceable, "");

                   double price;

                   // Parse the string                     
                   try
                   {
                       price = Double.parseDouble(cleanString);
                   }
                   catch(java.lang.NumberFormatException e)
                   {
                       price = 0;
                   }

                   // If we don't see a decimal, then the user must have deleted it.
                   // In that case, the number must be divided by 100, otherwise 1
                   int shrink = 1;
                   if(!(s.toString().contains(".")))
                   {
                       shrink = 100;
                   }

                   // Reformat the number
                   String formated = currencyFormat.format((price / shrink));

                   current = formated;
                   [yourtextfield].setText(formated);
                   [yourtextfield].setSelection(Math.min(selection, [yourtextfield].getText().length()));

                   [yourtextfield].addTextChangedListener(this);
                }
        }


        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after)
        {

        }


        @Override
        public void afterTextChanged(Editable s)
        {
        }
    });

基于上述一些答案，我创建了一个MoneyTextWatcher，您可以使用它，如下所示：

priceEditText.addTextChangedListener(new MoneyTextWatcher(priceEditText));

下面是课程：

public class MoneyTextWatcher implements TextWatcher {
    private final WeakReference<EditText> editTextWeakReference;

    public MoneyTextWatcher(EditText editText) {
        editTextWeakReference = new WeakReference<EditText>(editText);
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    }

    @Override
    public void afterTextChanged(Editable editable) {
        EditText editText = editTextWeakReference.get();
        if (editText == null) return;
        String s = editable.toString();
        if (s.isEmpty()) return;
        editText.removeTextChangedListener(this);
        String cleanString = s.replaceAll("[$,.]", "");
        BigDecimal parsed = new BigDecimal(cleanString).setScale(2, BigDecimal.ROUND_FLOOR).divide(new BigDecimal(100), BigDecimal.ROUND_FLOOR);
        String formatted = NumberFormat.getCurrencyInstance().format(parsed);
        editText.setText(formatted);
        editText.setSelection(formatted.length());
        editText.addTextChangedListener(this);
    }
}

公共类MoneyTextWatcher实现TextWatcher{
私有最终WeakReference editTextWeakReference；
public MoneyTextWatcher（编辑文本）{
editTextWeakReference=新的WeakReference（editText）；
}

String formatted=NumberFormat.getCurrencyInstance（）.format（已解析）；

editText.setSelection（格式化的.length（））；
editText.addTextChangedListener（此）；
}
}

尽管这里有很多答案，但我还是想分享我在其中找到的这段代码，因为我相信这是最可靠、最清晰的答案

class CurrencyTextWatcher implements TextWatcher {

    boolean mEditing;

    public CurrencyTextWatcher() {
        mEditing = false;
    }

    public synchronized void afterTextChanged(Editable s) {
        if(!mEditing) {
            mEditing = true;

            String digits = s.toString().replaceAll("\\D", "");
            NumberFormat nf = NumberFormat.getCurrencyInstance();
            try{
                String formatted = nf.format(Double.parseDouble(digits)/100);
                s.replace(0, s.length(), formatted);
            } catch (NumberFormatException nfe) {
                s.clear();
            }

            mEditing = false;
        }
    }

    public void beforeTextChanged(CharSequence s, int start, int count, int after) { }

    public void onTextChanged(CharSequence s, int start, int before, int count) { }

}

希望有帮助。

我使用它允许用户输入货币，并将其从字符串转换为int，存储在db中，然后再次从int转换回string

我从中获得了这个，并将其更改为符合葡萄牙货币格式

如果您的json货币字段是数字类型（而不是字符串），那么它可能是3.1、3.15或仅仅是3。因为json会自动对数字字段进行舍入

在这种情况下，您可能需要对其进行四舍五入以正确显示（并在以后能够在输入字段上使用掩码）：

为什么需要这样做

所有答案都指向在输入judding时删除货币符号，因为您收到了美分，因此形成dolar+cents/100=dolar，cents。但是，如果您的json货币字段是数字类型（而不是字符串），它将舍入您的美分，它可能是3、3.1或3.15。

我使用implements TextWatcher将类更改为使用巴西货币格式，并在编辑值时调整光标位置
