EditText phone number format input, delete case

When we enter a phone number, we usually cut a longer phone number. This kind of words effect will be very much better. The monitoring of edittext can easily achieve this requirement. Just need us to the corresponding EditText plus a listener on the OK. Put on a watcher I wrote.

public static class Mytextwatcher implements Textwatcher {private EditText numberedittext;private Button ConfirmButton; int Beforelen = 0;int Afterlen = 0;public mytextwatcher (EditText numberedittext, Button ConfirmButton) {This.numbereditte XT = Numberedittext;this.confirmbutton = ConfirmButton;} @Overridepublic void OnTextChanged (charsequence s, int start, int before,int count) {} @Overridepublic void Beforetextchan Ged (charsequence s, int start, int count,int after) {Beforelen = S.length ();} @Overridepublic void aftertextchanged (Editable s) {String txt = numberedittext.gettext (). toString (); Afterlen = Txt.length (); if (Afterlen > Beforelen) {if (txt.length () = = 4 | | txt.length () = = 9) {Numberedittext.settext (new STRINGB Uffer (TXT). Insert (Txt.length ()-1, ""). ToString ()), Numberedittext.setselection (Numberedittext.gettext (). Length () );}} else {if (Txt.startswith (")") {Numberedittext.settext (new StringBuffer (TXT). Delete (afterLen-1, Afterlen). ToString () ); Numberedittext.setselection (numberEdittext.gettext (). Length ());}}} 

It only needs new watcher when it is used. Passing in the current edittext can
