Kotlin |Java

open class PhoneNumberFormattingTextWatcher : TextWatcher

kotlin.Any
↳	android.telephony.PhoneNumberFormattingTextWatcher

---

This class was deprecated in API level 35.

This is a thin wrapper on a `libphonenumber` `AsYouTypeFormatter`; it is recommended to use that instead.

Watches a android.widget.TextView and if a phone number is entered will format it.

Stop formatting when the user

• Inputs non-dialable characters
• Removes the separator in the middle of string.

The formatting will be restarted once the text is cleared.

Public methods

afterTextChanged

Added in API level 1

open fun afterTextChanged(s: Editable!): Unit

Deprecated: Deprecated in Java.

This method is called to notify you that, somewhere within s, the text has been changed. It is legitimate to make further changes to s from this callback, but be careful not to get yourself into an infinite loop, because any changes you make will cause this method to be called again recursively. (You are not told where the change took place because other afterTextChanged() methods may already have made other changes and invalidated the offsets. But if you need to know here, you can use Spannable.setSpan in onTextChanged to mark your place and then look up from here where the span ended up.

beforeTextChanged

Added in API level 1

open fun beforeTextChanged(
    s: CharSequence!, 
    start: Int, 
    count: Int, 
    after: Int
): Unit

Deprecated: Deprecated in Java.

This method is called to notify you that, within s, the count characters beginning at start are about to be replaced by new text with length after. It is an error to attempt to make changes to s from this callback.

onTextChanged

Added in API level 1

open fun onTextChanged(
    s: CharSequence!, 
    start: Int, 
    before: Int, 
    count: Int
): Unit

Deprecated: Deprecated in Java.

This method is called to notify you that, within s, the count characters beginning at start have just replaced old text that had length before. It is an error to attempt to make changes to s from this callback.
