Custom input phone number automatically add separators

A simple control, that is, add some logic to deal with, it seems to be directly monitoring, package up a convenient point

 Public classAccounttxtviewextendsAndroid.support.v7.widget.AppCompatEditText {Private Final CharCUT = '-';  PublicAccounttxtview (Context context) {Super(context); }     PublicAccounttxtview (Context context, AttributeSet attrs) {Super(context, attrs); }     PublicAccounttxtview (context context, AttributeSet attrs,intdefstyleattr) {        Super(context, attrs, defstyleattr); } @Overrideprotected voidOnTextChanged (charsequence text,intStartintLengthbefore,intlengthafter) {        if(Text = =NULL|| Text.length () = = 0)            return; StringBuilder SB=NewStringBuilder ();  for(inti = 0; I < text.length (); i++) {//Add a separator            if(I! = 3 && I! = 8 && Text.charat (i) = =CUT) {                Continue; } Else{sb.append (Text.charat (i)); if((sb.length () = = 4 | | sb.length () = = 9)                        && Sb.charat (Sb.length ()-1)! =CUT) {Sb.insert (sb.length ()-1, CUT); }            }        }        //prevent setting values multiple times        if(!sb.tostring ().

Also easy to use

And then the effect comes out.

Enter the fourth when the '-' delimiter is automatically populated and then delete the '-' separator automatically
