android - how to get my arraylist string value? -

hi created xml based android app, used sax parser. have 1 doubt, uncertainty how parse arraylist value 1 activity activity. 1st explain project, first screen display 2spinner , 1 gird view.

this main activity total source:

please see above code , see lines: 1. sdcardimages.setonitemclicklistener 2. mspec_list array list , tab layout source code link: 1. http://paste.org/44196 2. http://paste.org/44195 please help me.

i not pass arraylist activity reference list. possible maintain arraylist in separate class. using static method , static variable instance can maintain info there.

public class mydata{ static private mydata instanceofmydata; arraylist<string> mystringlist = new arraylist<string>(); static synchronized public mydata getinstance() { if (instanceofmydata == null) instanceofmydata = new mydata(); homecoming instanceofmydata; } static public arraylist<?> getmystringlist(mydata instance){ homecoming instance.mystringlist; } }

then in of activities can access arraylist 2 calls:

mydata mydata = mydata.getinstance(); arraylist<?> mystrings = mydata.getmystringlist(mydata);

you can utilize reference mystrings view, add together or remove items collection.
