android - Close app and reopen Continue read text -


this simple code multi text in 1 textview,

int stringidlist[] = {r.string.text1, r.string.text2, r.string.text3, r.string.text4};     int stringlistcounter = 0;     textview text1;     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         button next = (button) findviewbyid(r.id.next1);         button previous = (button) findviewbyid(r.id.pre1);         text1 = (textview) findviewbyid(r.id.textview1);         next.setonclicklistener(this);         previous.setonclicklistener(this);      @override     public void onclick(view v) {           int id = v.getid();           if(id == r.id.next1 && stringlistcounter < stringidlist.length - 1) {                 stringlistcounter++;                } else if (id == r.id.pre1 && stringlistcounter > 0) {                 stringlistcounter--;               }               text1.settext(stringidlist[stringlistcounter]);               }

my problem :when close app , again reopen app want continue last text read before close apps when close , reopen app begin first text now.

u should use sharedpreference class save text index. 

@override public void onpause() {     super.onpause();      sharedpreferences pref = preferencemanager.getdefaultsharedpreferences(getactivity());     pref.edit().putint("stringlistcounter", stringlistcounter).commit(); }  @override public void onresume() {     super.onresume();     sharedpreferences pref = preferencemanager.getdefaultsharedpreferences(getactivity());     stringlistcounter = pref.getint("stringlistcounter", 0); }
