first of all, wasting lot of space creating new hashmap<string, string> every time. not sure why have arraylist of hashmaps. having 1 or other should sufficient.

you can create class called candy such:

class candy {     private string id;     private string code;     candy(string id, string code) {         this.id = id;         this.code = code;     }     public string getid() { return this.id; }     public string getcode() { return this.code; } } 

then can define arraylist , instantiate in beginning of oncreate():

// don't use starting capital letters methods, classes have first capital letter // renamed myarrlist myarrlist arraylist<candy> myarrlist; // ... void oncreate() { // ...     myarrlist = new arraylist<candy>(); // ... } 

and populate like:

myarrlist.add(new candy("butterscotch", "rs 10")); myarrlist.add(new candy("birthday cake", "rs 100")); myarrlist.add(new candy("black crunch", "rs 102")); myarrlist.add(new candy("industrial chocolate", "rs 200")); myarrlist.add(new candy("coffee molasses chip", "rs 500")); 

now can use getter methods of candy class called getid() , getcode().

change:

// colid textview txtid = (textview) convertview.findviewbyid(r.id.nm); txtid.settext(myarrlist.get(position).get("id") +".");     // colcode textview txtcode = (textview) convertview.findviewbyid(r.id.rat); txtcode.settext(myarrlist.get(position).get("code")); 

to:

// colid textview txtid = (textview) convertview.findviewbyid(r.id.nm); txtid.settext(myarrlist.get(position).getid() +"."); // colcode textview txtcode = (textview) convertview.findviewbyid(r.id.rat); txtcode.settext(myarrlist.get(position).getcode()); 

now answer question, assume want store text within edittext field arraylist.

you can create class arraylist object holds string objects , instantiate in oncreate().

arraylist<string> edittextvalues; // ... void oncreate() { // ...     edittextvalues = new arraylist<string>(); // ... } 

now can add text edittext arraylist:

edittext text = (edittext)findviewbyid(r.id.your_id); string value = text.gettext().tostring(); edittextvalues.add(value); 

and use edittextvalues need them.
