Multiple EditText in Android -

if have,say 20 edittext fields in program...and @ time want access 2 of them...then next 2...then next 2...and on....can using array of exittexts?? if yes can please provide me small example...

accessing each , every edittext separately can tedious job...i've tried implement in array...but every time giving me null pointer exception...all ids correctly provided...plus code works when provide each single edittext separately.

here code::

edittext e11,e12,e13,e21,e22,e23,e31,e32,e33,e41,e42,e43,e51,e52,e53,e61,e62,e63,e71,e72,e73,e81,e82,e83,e91,e92,e93,e101,e102,e103;  edittext arr[]={e11,e12,e13,e21,e22,e23,e31,e32,e33,e41,e42,e43,e51,e52,e53,e61,e62,e63,e71,e72,e73,e81,e82,e83,e91,e92,e93,e101,e102,e103};  string ch1="",ch2="',ch3="";  for(c=0 9) {     ch1=arr[(4*c)].gettext().tostring();     ch2=arr[(4*c)+1].gettext().tostring();     ch3=arr[(4*c)+2].gettext().tostring();  } 

the loop giving me null pointer exception...even if set values edittexts hard coded.

you can use droidquery select edittexts, , use each method iterate on of them. can add textwatcher or clicklistener, or lot of other things en masse simple commands. example, select edittexts, use:

$ droidquery = $.with(this).selectbytype("android.widget.edittext"); 

each edittext can retrieved using view(int) method. if want 2 @ time, can this:

edittext[] ets = new edittext[]{(edittext) droidquery.view(0), (edittext) droidquery.view(1)};//note: can size of current droidquery selection size() method. //todo eta.  

the best way, however, each 1 follows:

$.with(this).selectbytype("android.widget.edittext").each(new function() {     @override     public void invoke($ droidquery, object... params) {         edittext e = (edittext) droidquery.view(0);         //todo manipulate e     } }); 

you can add listeners on of them this:

$.with(this).selectbytype("android.widget.edittext").click(new function() {     @override     public void invoke($ droidquery, object... params) {         edittext e = (edittext) droidquery.view(0);         //todo handle e clicked     } }); 

to add textwatcher, can this:

$.with(this).selectbytype("android.widget.edittext").change(new function() {     @override     public void invoke($ droidquery, object... params) {         edittext e = (edittext) droidquery.view(0);         //todo handle e after text has changed.     } }); 

you can lot more library, sure read docs.
