在 Android 中格式化 EditText 的电话号码

Question

我正在制作一个简单的地址簿应用程序（针对 4.2），它需要姓名、地址、城市、州、邮政编码和电话。

我想将输入的电话号码格式化为电话号码 (XXX) XXX-XXXX，但我需要将该值作为字符串提取出来，以便在保存时将其存储在我的数据库中。 我怎样才能做到这一点？？ 我为“电话号码”输入设置了 EditText ，但这显然不会做太多。

Answer 1

只需使用PhoneNumberFormattingTextWatcher ，只需调用：

editText.addTextChangedListener(new PhoneNumberFormattingTextWatcher());

---

添加
明确地说，PhoneNumberFormattingTextWatcher 的主干是 PhoneNumberUtils 类。 不同之处在于 TextWatcher 维护 EditText，而您每次更改其内容时都必须调用PhoneNumberUtils.formatNumber() 。

Answer 2

有一个名为PhoneNumberUtils的库可以帮助您处理电话号码转换和比较。 例如，使用...

EditText text = (EditText) findViewById(R.id.editTextId);
PhoneNumberUtils.formatNumber(text.getText().toString())

...以标准格式格式化您的号码。

PhoneNumberUtils.compare(String a, String b);

...有助于模糊比较。 还有很多。 查看http://developer.android.com/reference/android/telephony/PhoneNumberUtils.html了解更多信息。

ps 将EditText 设置为phone已经是一个不错的选择； 最终添加digits可能会有所帮助，例如在您的布局中，它看起来像......

<EditText
    android:id="@+id/editTextId"
    android:inputType="phone"
    android:digits="0123456789+" 
/> 

Answer 3

只需使用这个：

在 Java 代码中：

editText.addTextChangedListener(new PhoneNumberFormattingTextWatcher());

在 XML 代码中：

<EditText
    android:id="@+id/etPhoneNumber"
    android:inputType="phone"/>

这段代码对我有用。 当编辑文本中的文本更改时，它将自动格式化。

Answer 4

我最近为 Android EditText 完成了类似的格式设置，例如 1 (XXX) XXX-XXXX。 请在下面找到代码。 只需使用 TextWatcher 子类作为文本更改侦听器：....

UsPhoneNumberFormatter addLineNumberFormatter = new UsPhoneNumberFormatter(
            new WeakReference<EditText>(mYourEditText));
    mYourEditText.addTextChangedListener(addLineNumberFormatter);

...

private class UsPhoneNumberFormatter implements TextWatcher {
    //This TextWatcher sub-class formats entered numbers as 1 (123) 456-7890
    private boolean mFormatting; // this is a flag which prevents the
                                    // stack(onTextChanged)
    private boolean clearFlag;
    private int mLastStartLocation;
    private String mLastBeforeText;
    private WeakReference<EditText> mWeakEditText;

    public UsPhoneNumberFormatter(WeakReference<EditText> weakEditText) {
        this.mWeakEditText = weakEditText;
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {
        if (after == 0 && s.toString().equals("1 ")) {
            clearFlag = true;
        }
        mLastStartLocation = start;
        mLastBeforeText = s.toString();
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before,
            int count) {
        // TODO: Do nothing
    }

    @Override
    public void afterTextChanged(Editable s) {
        // Make sure to ignore calls to afterTextChanged caused by the work
        // done below
        if (!mFormatting) {
            mFormatting = true;
            int curPos = mLastStartLocation;
            String beforeValue = mLastBeforeText;
            String currentValue = s.toString();
            String formattedValue = formatUsNumber(s);
            if (currentValue.length() > beforeValue.length()) {
                int setCusorPos = formattedValue.length()
                        - (beforeValue.length() - curPos);
                mWeakEditText.get().setSelection(setCusorPos < 0 ? 0 : setCusorPos);
            } else {
                int setCusorPos = formattedValue.length()
                        - (currentValue.length() - curPos);
                if(setCusorPos > 0 && !Character.isDigit(formattedValue.charAt(setCusorPos -1))){
                    setCusorPos--;
                }
                mWeakEditText.get().setSelection(setCusorPos < 0 ? 0 : setCusorPos);
            }
            mFormatting = false;
        }
    }

    private String formatUsNumber(Editable text) {
        StringBuilder formattedString = new StringBuilder();
        // Remove everything except digits
        int p = 0;
        while (p < text.length()) {
            char ch = text.charAt(p);
            if (!Character.isDigit(ch)) {
                text.delete(p, p + 1);
            } else {
                p++;
            }
        }
        // Now only digits are remaining
        String allDigitString = text.toString();

        int totalDigitCount = allDigitString.length();

        if (totalDigitCount == 0
                || (totalDigitCount > 10 && !allDigitString.startsWith("1"))
                || totalDigitCount > 11) {
            // May be the total length of input length is greater than the
            // expected value so we'll remove all formatting
            text.clear();
            text.append(allDigitString);
            return allDigitString;
        }
        int alreadyPlacedDigitCount = 0;
        // Only '1' is remaining and user pressed backspace and so we clear
        // the edit text.
        if (allDigitString.equals("1") && clearFlag) {
            text.clear();
            clearFlag = false;
            return "";
        }
        if (allDigitString.startsWith("1")) {
            formattedString.append("1 ");
            alreadyPlacedDigitCount++;
        }
        // The first 3 numbers beyond '1' must be enclosed in brackets "()"
        if (totalDigitCount - alreadyPlacedDigitCount > 3) {
            formattedString.append("("
                    + allDigitString.substring(alreadyPlacedDigitCount,
                            alreadyPlacedDigitCount + 3) + ") ");
            alreadyPlacedDigitCount += 3;
        }
        // There must be a '-' inserted after the next 3 numbers
        if (totalDigitCount - alreadyPlacedDigitCount > 3) {
            formattedString.append(allDigitString.substring(
                    alreadyPlacedDigitCount, alreadyPlacedDigitCount + 3)
                    + "-");
            alreadyPlacedDigitCount += 3;
        }
        // All the required formatting is done so we'll just copy the
        // remaining digits.
        if (totalDigitCount > alreadyPlacedDigitCount) {
            formattedString.append(allDigitString
                    .substring(alreadyPlacedDigitCount));
        }

        text.clear();
        text.append(formattedString.toString());
        return formattedString.toString();
    }

}

Answer 5

也许下面的示例项目可以帮助您；

https://github.com/reinaldoarrosi/MaskedEditText

该项目包含一个视图类调用MaskedEditText 。 首先，您应该将它添加到您的项目中。

然后在项目的 res/values/attrs.xml 文件中添加以下 xml 部分；

<resources>
    <declare-styleable name="MaskedEditText">
        <attr name="mask" format="string" />
        <attr name="placeholder" format="string" />
    </declare-styleable>
</resources>

然后您就可以使用MaskedEditText视图了。

最后，您应该在您的 xml 文件中添加 MaskedEditText，如下所示；

<packagename.currentfolder.MaskedEditText
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/maskedEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:text="5"
    app:mask="(999) 999-9999"
    app:placeholder="_" >

当然，您可以以编程方式使用它。

完成这些步骤后，添加MaskedEditText将如下所示；

以编程方式，如果您想将其文本值设为未屏蔽，您可以使用下面的行；

maskedEditText.getText(true);

要获取掩码值，您可以在getText方法中发送false值而不是true值。

Answer 6

您需要创建一个类：

public class PhoneTextFormatter implements TextWatcher {

    private final String TAG = this.getClass().getSimpleName();

    private EditText mEditText;

    private String mPattern;

    public PhoneTextFormatter(EditText editText, String pattern) {
        mEditText = editText;
        mPattern = pattern;
        //set max length of string
        int maxLength = pattern.length();
        mEditText.setFilters(new InputFilter[]{new InputFilter.LengthFilter(maxLength)});
    }

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

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        StringBuilder phone = new StringBuilder(s);

        Log.d(TAG, "join");

        if (count > 0 && !isValid(phone.toString())) {
            for (int i = 0; i < phone.length(); i++) {
                Log.d(TAG, String.format("%s", phone));
                char c = mPattern.charAt(i);

                if ((c != '#') && (c != phone.charAt(i))) {
                    phone.insert(i, c);
                }
            }

            mEditText.setText(phone);
            mEditText.setSelection(mEditText.getText().length());
        }
    }

    @Override
    public void afterTextChanged(Editable s) {

    }

    private boolean isValid(String phone)
    {
        for (int i = 0; i < phone.length(); i++) {
            char c = mPattern.charAt(i);

            if (c == '#') continue;

            if (c != phone.charAt(i)) {
                return false;
            }
        }

        return true;
    }
}

使用方法如下：

phone = view.findViewById(R.id.phone);
phone.addTextChangedListener(new PhoneTextFormatter(phone, "+7 (###) ###-####"));

Answer 7

按照此答案中的说明设置 EditText 掩码的格式。

https://stackoverflow.com/a/34907607/1013929

之后，您可以使用以下命令从掩码字符串中捕获原始数字：

String phoneNumbers = maskedString.replaceAll("[^\\d]", "");

        case 10:
            etyEditText.setEditText(new StringBuilder(text).insert(text.length() - 1, "-").toString());
            etyEditText.setSelection(etyEditText.getText().length());
            break;
    }

Answer 10

您可以使用具有模式匹配的正则表达式从字符串中提取数字。

    String s="";
    Pattern p = Pattern.compile("\\d+");
    Matcher m = p.matcher("(1111)123-456-789"); //editText.getText().toString()                                      
    while (m.find()) {
    s=s+m.group(0);
    }
    System.out.println("............"+s);    

    Output : ............1111123456789

您可以使用 spawn 来格式化 Android 中的电话号码。 此解决方案比其他解决方案更好，因为它不会更改输入文本。 格式仍然纯粹是视觉上的。

implementation 'com.googlecode.libphonenumber:libphonenumber:7.0.4'

格式化程序类：

open class PhoneNumberFormatter : TransformationMethod {
private val mFormatter: AsYouTypeFormatter = PhoneNumberUtil.getInstance().getAsYouTypeFormatter(Locale.getDefault().country)

override fun getTransformation(source: CharSequence, view: View): CharSequence {
    val formatted = format(source)
    if (source is Spannable) {
        setSpans(source, formatted)
        return source
    }
    return formatted
}
override fun onFocusChanged(view: View?, sourceText: CharSequence?, focused: Boolean, direction: Int, previouslyFocusedRect: Rect?) = Unit

private fun setSpans(spannable: Spannable, formatted: CharSequence): CharSequence {

    spannable.clearSpawns()

    var charterIndex = 0
    var formattedIndex = 0
    var spawn = ""
    val spawns: List<String> = spannable
        .map {
            spawn = ""
            charterIndex = formatted.indexOf(it, formattedIndex)
            if (charterIndex != -1){
                spawn = formatted.substring(formattedIndex, charterIndex-1)
                formattedIndex = charterIndex+1
            }
            spawn
        }

    spawns.forEachIndexed { index, sequence ->
        spannable.setSpan(CharterSpan(sequence), index, index + 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
    }

    return formatted
}

private fun Spannable.clearSpawns() =
    this
        .getSpans(0, this.length, CharterSpan::class.java)
        .forEach { this.removeSpan(it) }

private fun format(spannable: CharSequence): String {
    mFormatter.clear()
    var formated = ""
    for (i in 0 until spannable.length) {
        formated = mFormatter.inputDigit(spannable[i])
    }
    return formated
}

private inner class CharterSpan(private val charters: String) : ReplacementSpan() {

    var space = 0

    override fun getSize(paint: Paint, text: CharSequence, start: Int, end: Int, fm: Paint.FontMetricsInt?): Int {
        space = Math.round(paint.measureText(charters, 0, charters.length))
        return Math.round(paint.measureText(text, start, end)) + space
    }

    override fun draw(canvas: Canvas, text: CharSequence, start: Int, end: Int, x: Float, top: Int, y: Int, bottom: Int, paint: Paint) {
        space = Math.round(paint.measureText(charters, 0, charters.length))
        canvas.drawText(text, start, end, x + space, y.toFloat(), paint)
        canvas.drawText(charters, x, y.toFloat(), paint)
    }
    }

}

用法：

editText.transformationMethod = formatter

    number1.setInputType(InputType.TYPE_CLASS_NUMBER|InputType.TYPE_CLASS_PHONE);
     number1.setKeyListener(DigitsKeyListener.getInstance("0123456789”));
      number1.setFilters(new InputFilter[] {new InputFilter.LengthFilter(14)}); // 14 is max digits
