java - Android: code refactoring advice -

i creating todo list kind of app. app 7 screens set target , complete that. screenshot here . while coding realized there lots of redundancy in code, like:

1> 7 day of week need create 7 fragments 7 fragments need perform same operations. can w/o 7 fragments?

2> there 15 checkboxes , 15 textview all-i need reference, perform onclick operations separately on each 1 , settext , gettext on each user try modify them.

here 1 of textview modify code:

 ptext2 = (textview) view.findviewbyid(r.id.p_textview2);         ptext2.setonlongclicklistener(new view.onlongclicklistener() {             @override             public boolean onlongclick(view view) {                 alertdialog.builder alertdialog = new alertdialog.builder(getactivity());                 alertdialog.settitle("target");                 alertdialog.setmessage("set target");                 final edittext input = new edittext(getactivity());                 alertdialog.setview(input);                 alertdialog.setpositivebutton("set", new dialoginterface.onclicklistener() {                     @override                     public void onclick(dialoginterface dialoginterface, int i) {                         string targetinp = input.gettext().tostring();                         ptext2.settext(targetinp);                         p2 = ptext2.gettext().tostring();                         addeventstodb();                     }                 });                 alertdialog.setnegativebutton("cancel", new dialoginterface.onclicklistener() {                     @override                     public void onclick(dialoginterface dialoginterface, int i) {                     }                 });                 alertdialog.show();                 return true;             }         }); 

similarly there 15 more textview , checkbox need 7 fragments. here full code of 1 of fragment

since kind of apps first app of users learning android development should done improve code?

edit: multiple buttons onclick listener's creating inner class , using switch button specific operations.

switch(view.getid()){     case r.id.id1:         //do         break; ..... }  

from this answer. need figure out 7 fragments (can done 1 fragment?)

what naming implementation of view.onlongclicklistener class like:

class ondayclicklistener extends view.onlongclicklistener {      @override     public boolean onlongclick(final view view) {         // here use view instead of ptext2     } } 

then use

ptext2.setonlongclicklistener(new ondayclicklistener()); // repeats every textbox
