android - how do i perform method for all iteration of for loop -

my code delete 1st file using button click want delete , unhide images using loop if statement true if(checkarr[i] == true) code perform first index file ot checked file delete 1st 1 delete do? how delete , copy checked item? how customize loop??

    unhide.setonclicklistener(new onclicklistener() { @override public void onclick(view arg0) {  (int = 0; < checkarr.length; i++) { if (checkarr[i] == true) {  db = new database(getbasecontext());     try {     db.createdatabase();        } catch (ioexception e1) {      e1.printstacktrace();     }   cursor datac = db .selectquery("select path photos name ='"+    currentfiles[i].getname() + "'");    bitmap bitmap = decodefile.decodefile(new file(root + "/"+ currentfiles[i].getname()));  try {         fileoutputstream outputstream = new fileoutputstream(new   file(datac.getstring(datac.getcolumnindex("path"))));      outputstream.write(decodefile.getbitmapasbytearray(bitmap)); outputstream.close(); } catch (exception e) { e.printstacktrace(); }  file file = new file(root + "/" + currentfiles[i].getname()); file.delete();  inflatelistview(currentfiles);   datac.close();    db.close(); } } 

i loop differently. i'd open database once, , i'd check see if intermediate steps working.

this more i'd recommend:

  unhide.setonclicklistener(new onclicklistener() {         @override         public void onclick(view arg0) {              try {                 db.createdatabase();                 (int = 0; < checkarr.length; i++) {                     if (checkarr[i] == true) {                         db = new database(getbasecontext());                         cursor datac = db.selectquery("select path photos name ='"+                                 currentfiles[i].getname() + "'");                         bitmap bitmap = decodefile.decodefile(new file(root + "/"+ currentfiles[i].getname()));                         if (datac.movetofirst() && bitmap != null) {                             fileoutputstream outputstream = new fileoutputstream(new                                     file(datac.getstring(datac.getcolumnindex("path"))));                              outputstream.write(decodefile.getbitmapasbytearray(bitmap));                             outputstream.close();                              file file = new file(root + "/" + currentfiles[i].getname());                             file.delete();                         } else {                             if (bitmap == null) {                                 log.v("your tag", "bitmap not found");                             } else {}                             log.v("your tag", "unable convert file");                         }                         datac.close();                     }                 }                 db.close();                  inflatelistview(currentfiles);             } catch (exception e1) {                 e1.printstacktrace();             }         }     } 

i'm not sure doing on things, that's direction i'd go in.
