我正在创建一个简单的地址簿应用程序(目标为4.2),其中包含姓名,地址,城市,州,邮编和电话。
我想将电话号码输入格式化为电话号码(XXX)XXX-XXXX,但我需要将值拉出为字符串,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?? 我将EditText设置为“电话号码”输入,但显然不会做太多。

只需使用PhoneNumberFormattingTextWatcher,只需致电:
editText.addTextChangedListener(new PhoneNumberFormattingTextWatcher());
<强>加成强>
需要说明的是,PhoneNumberFormattingTextWatcher的backbone是PhoneNumberUtils类。区别在于TextWatcher维护EditText,而每次更改内容时都必须调用PhoneNumberUtils.formatNumber()
。
答案 1 :(得分:48)
有一个名为PhoneNumberUtils的图书馆可以帮助您应对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。
P.S。将EditText设置为phone
已经是一个不错的选择;最后添加digits
可能会有所帮助,例如在你的布局中它看起来像......
<EditText
android:id="@+id/editTextId"
android:inputType="phone"
android:digits="0123456789+"
/>
答案 2 :(得分:21)
只需使用:
在Java代码中:
editText.addTextChangedListener(new PhoneNumberFormattingTextWatcher());
在XML代码中:
<EditText
android:id="@+id/etPhoneNumber"
android:inputType="phone"/>
此代码适合我。在编辑文本中更改文本时,它会自动格式化。
答案 3 :(得分:19)
我最近做了类似的格式,如1(XXX)XXX-XXXX for Android EditText。请在下面找到代码。只需使用TextWatcher子类作为文本更改的侦听器: ....
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();
}
}

也许以下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,您应该在项目中添加。
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。
最后,您应该在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,您可以通过编程方式使用它。
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视为未屏蔽,则可以使用以下行;
maskedEditText.getText(true);
要获取屏蔽值,您可以在false
方法中发送true
值而不是getText
值。

您可以使用带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

您可以使用衍生工具在Android中格式化电话号码。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。格式保持纯视觉效果。
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)
