android - changing focus on multiple edittext boxes -

i've written code test if user has changed values in of 6 edittext boxes, code looks bulky , redundant. i'm wondering if there more elegant way this.

the user inputs numbers of 6 edittext boxes, , after each entry, calculation routine checks sure boxes have valid numbers before doing calculation. kistener has fire on lost foucus number in box before calculations done. , outputing result. if user want go , change value in 1 of 6 edittext boxes, calulation routine runs again.been i've set 6 listeners in oncreate section each edittext box. have 6 separate routines test each hasfocus==false.

within oncreate section set listener each of 6 user input edottext boxes:

et1.setonfocuschangelistener(this); .    .   . . et6.setonfocuschangelistener(this); 

then have method check if edittext box has lost focus, suggesting theat user changed data, , therfore re-run calulations.
check each of 6 user input edittext boxes follows:

@override public void onfocuschange(view v, boolean hasfocus) {   if ((v == findviewbyid(r.id.et1)) && (hasfocus==false))         {do calculations }      .     .     .     .     if ((v == findviewbyid(r.id.et6)) && (hasfocus==false))         {do calculations }   } 

forgive me if i've made typos in code above. runs on platform, learn better way this.

i think checking view has lost focus unnecessary, unless calculations different depending on box has lost focus. if calculations same, try:

public void onfocuschange(view v, boolean hasfocus) {     if(!hasfocus) {         //do calculations     } } 

if you're caring 1 of 6 has lost focus, time focus changes, check see if it's not focused, perform calculations.

also, reference, it's more efficient check if(v.getid() == r.id.et1) rather calling findviewbyid() unnecessarily.

edit: thinking, haven't tested this, might more effective, cause calculations occur if value changed:

private string last;  public void onfocuschange(view v, boolean hasfocus) {     if(hasfocus) {         last = ((edittext)v).gettext().tostring();           } else {         if(!((edittext)v).gettext().tostring().equals(last)) {             //do calculations         }     } }
