I have a TextView that displays the user’s phone number, I would like to display in my application a mask that leaves the phone number in the format (xx) xxxx-xxxxx. How could I do that?

I used to do this:
I have static methods in my Phonemaskcontroller class, which clean and add formatting:
public static String clearFormating(String phoneNumber) {
phoneNumber = phoneNumber.replace("(", "").replace(")", "").replace("-", "")
.replace(" ", "");
return phoneNumber;
}
public static String formatPhoneNumber(String phoneNumber) {
StringBuilder sb = new StringBuilder();
if (phoneNumber.length() >= 5 && phoneNumber.length() < 9) {
sb.append(phoneNumber.subSequence(0, 4));
sb.append('-');
sb.append(phoneNumber.subSequence(4, phoneNumber.length()));
} else if (phoneNumber.length() == 9) {
sb.append(phoneNumber.subSequence(0, 5));
sb.append('-');
sb.append(phoneNumber.subSequence(5, phoneNumber.length()));
} else if (phoneNumber.length() == 10) {
sb.append("(");
sb.append(phoneNumber.subSequence(0, 2));
sb.append(") ");
sb.append(phoneNumber.subSequence(2, 6));
sb.append("-");
sb.append(phoneNumber.subSequence(6, phoneNumber.length()));
} else if (phoneNumber.length() == 11) {
if (phoneNumber.startsWith("0")) {
sb.append("(");
sb.append(phoneNumber.subSequence(0, 3));
sb.append(") ");
sb.append(phoneNumber.subSequence(3, 7));
sb.append("-");
sb.append(phoneNumber.subSequence(7, phoneNumber.length()));
} else {
sb.append("(");
sb.append(phoneNumber.subSequence(0, 2));
sb.append(") ");
sb.append(phoneNumber.subSequence(2, 7));
sb.append("-");
sb.append(phoneNumber.subSequence(7, phoneNumber.length()));
}
} else if (phoneNumber.length() == 12) {
if (phoneNumber.startsWith("0")) {
sb.append("(");
sb.append(phoneNumber.subSequence(0, 3));
sb.append(") ");
sb.append(phoneNumber.subSequence(3, 8));
sb.append("-");
sb.append(phoneNumber.subSequence(8, phoneNumber.length()));
} else {
sb.append("(");
sb.append(phoneNumber.subSequence(0, 2));
sb.append(" ");
sb.append(phoneNumber.subSequence(2, 4));
sb.append(") ");
sb.append(phoneNumber.subSequence(4, 8));
sb.append("-");
sb.append(phoneNumber.subSequence(8, phoneNumber.length()));
}
} else if (phoneNumber.length() == 13) {
if (phoneNumber.startsWith("0")) {
sb.append("(");
sb.append(phoneNumber.subSequence(0, 3));
sb.append(" ");
sb.append(phoneNumber.subSequence(3, 5));
sb.append(") ");
sb.append(phoneNumber.subSequence(5, 9));
sb.append("-");
sb.append(phoneNumber.subSequence(9, phoneNumber.length()));
} else {
sb.append("(");
sb.append(phoneNumber.subSequence(0, 2));
sb.append(" ");
sb.append(phoneNumber.subSequence(2, 4));
sb.append(") ");
sb.append(phoneNumber.subSequence(4, 9));
sb.append("-");
sb.append(phoneNumber.subSequence(9, phoneNumber.length()));
}
} else if (phoneNumber.length() == 14) {
sb.append("(");
sb.append(phoneNumber.subSequence(0, 3));
sb.append(" ");
sb.append(phoneNumber.subSequence(3, 5));
sb.append(") ");
sb.append(phoneNumber.subSequence(5, 10));
sb.append("-");
sb.append(phoneNumber.subSequence(10, phoneNumber.length()));
} else {
sb.append(phoneNumber);
}
return sb.toString();
}
In my edittext-working Fragment and/or Activity, I add the following parameter in edittext:
yourEdittext.addTextChangedListener(filterTextWatcherPhoneNumber);
And the following method:
private TextWatcher filterTextWatcherPhoneNumber = new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
try {
if (isUpdatingNumber) {
isUpdatingNumber = false;
return;
}
String result = PhoneMaskController.clearFormating(s.toString());
if (result.length() < 15) {
result = PhoneMaskController.formatPhoneNumber(result);
} else {
result = result.substring(0, 15);
result = PhoneMaskController.formatPhoneNumber(result);
}
isUpdatingNumber = true;
itemUserPhone.setText(result);
itemUserPhone
.setSelection(itemUserPhone.getText().length());
} catch (Exception e) {
}
}
};

Whereas the number is in one long, you can use String.format():
long telefone = 55123456789L; // (55) 1234-56789
// (xx) xxxx-xxxxx
String s = String.format("(%02d) %04d-%05d",
(telefone / 1000000000L) % 100, (telefone / 10000) % 10000, telefone % 100000);
textView.setText(s);
The divisions remove the right part of the number while the rest remove the left part of the long. I used long for the int not enough bits for 11 digits of the number.
If the number is available in three integers, then you can use:
// (xx) xxxx-xxxxx
// (99) 1234-56789
int codigo = 99;
int esquerda = 1234;
int direita = 56789;
String s = String.format("(%02d) %04d-%05d", codigo, esquerda, direita);
textView.setText(s);

Hello Matthew, are you using some framework for development? Phonegap or other? Pure Java? Put a snippet of your code so we know at least what this textView looks like.

@Pauloroberto edited the question with more information.
– Mateus Carvalho
A Jquery or Javascript would help you in this case? Or would it have to be something in java anyway?
– Paulo Roberto
From what I understand, you have a number with no format and want to somehow display this number on a
TextViewwith the given format, is that it? When you say "mask", I understand it to be in aEditText, so that when the user is typing, the format is applied.– Paulo Rodrigues
Exact @Paulorodrigues, really Mask refers to Edittext, I changed the question.
– Mateus Carvalho
@Pauloroberto has to be java
– Mateus Carvalho
The number is available in what way to you? Like three integers or a long? Or string?
