Store value in SharedPreference and get From it in android -

i new android , have been using code save value of checkboxes when app closes works fine (in settings.class)

        public void putbooleaninpreferences(boolean ischecked,string key){         sharedpreferences sharedpreferences =     this.getpreferences(activity.mode_private);         sharedpreferences.editor editor = sharedpreferences.edit();         editor.putboolean(key, ischecked);         editor.commit();                 }         public boolean getbooleanfrompreferences(string key){         sharedpreferences sharedpreferences = this.getpreferences(activity.mode_private);         boolean ischecked = sharedpreferences.getboolean(key, false);         return ischecked;                 } 

but want use same saved value in activity (progress.class)

here activities

settings.class

          checkbox_one = (checkbox) findviewbyid(r.id.checkbox1);            boolean ischecked = getbooleanfrompreferences("ischecked");           log.i("start",""+ischecked);           checkbox_one.setchecked(ischecked);           //checkbox_one.setchecked(true);//enable default           checkbox_one.setoncheckedchangelistener(new oncheckedchangelistener() {              @override             public void oncheckedchanged(compoundbutton view, boolean ischecked) {                 log.i("boolean",""+ischecked);                 settings.this.putbooleaninpreferences(ischecked,"ischecked");             }           });            checkbox_two = (checkbox) findviewbyid(r.id.checkbox2);            boolean ischeckedtwo = getbooleanfrompreferences("ischeckedtwo");           checkbox_two.setchecked(ischeckedtwo );           //checkbox_two.setchecked(true);//enable default           checkbox_two.setoncheckedchangelistener(new oncheckedchangelistener() {             @override             public void oncheckedchanged(compoundbutton view, boolean ischecked) {                  settings.this.putbooleaninpreferences(ischecked,"ischeckedtwo");             }           });            checkbox_three = (checkbox) findviewbyid(r.id.checkbox3);            boolean ischeckedthree = getbooleanfrompreferences("ischeckedthree");           checkbox_three.setchecked(ischeckedthree );           checkbox_three.setoncheckedchangelistener(new oncheckedchangelistener() {             @override             public void oncheckedchanged(compoundbutton view, boolean ischecked) {                  settings.this.putbooleaninpreferences(ischecked,"ischeckedthree");             }           });            checkbox_four = (checkbox) findviewbyid(r.id.checkbox4);            boolean ischeckedfour = getbooleanfrompreferences("ischeckedfour");           checkbox_four.setchecked(ischeckedfour );           //checkbox_four.setchecked(true);//enable default           checkbox_four.setoncheckedchangelistener(new oncheckedchangelistener() {             @override             public void oncheckedchanged(compoundbutton view, boolean ischecked) {                  settings.this.putbooleaninpreferences(ischecked,"ischeckedfour");             }           });            checkbox_five = (checkbox) findviewbyid(r.id.checkbox5);            boolean ischeckedfive = getbooleanfrompreferences("ischeckedfive");           checkbox_five.setchecked(ischeckedfive );           checkbox_five.setoncheckedchangelistener(new oncheckedchangelistener() {             @override             public void oncheckedchanged(compoundbutton view, boolean ischecked) {                  settings.this.putbooleaninpreferences(ischecked,"ischeckedfive");             }           });          }          public void putbooleaninpreferences(boolean ischecked,string key){         sharedpreferences sharedpreferences = this.getpreferences(activity.mode_private);         sharedpreferences.editor editor = sharedpreferences.edit();         editor.putboolean(key, ischecked);         editor.commit();                 }         public boolean getbooleanfrompreferences(string key){         sharedpreferences sharedpreferences = this.getpreferences(activity.mode_private);         boolean ischecked = sharedpreferences.getboolean(key, false);         return ischecked;                 }         //-------------------------// 

and here progress.class

        progressbar1 = (progressbar) findviewbyid(r.id.progressbar1);         progressbar2 = (progressbar) findviewbyid(r.id.progressbar2);         checkbox1 = (checkbox) findviewbyid(r.id.checkbox1);         checkbox2 = (checkbox) findviewbyid(r.id.checkbox2);          checkbox1.setoncheckedchangelistener(new compoundbutton.oncheckedchangelistener() {             @override             public void oncheckedchanged(compoundbutton buttonview, boolean ischecked) {                 updateprogressbars();             }         });          checkbox2.setoncheckedchangelistener(new compoundbutton.oncheckedchangelistener() {             @override             public void oncheckedchanged(compoundbutton buttonview, boolean ischecked) {                 updateprogressbars();             }         });         }          public void updateprogressbars() {            progressbar1.setvisibility(view.gone);           progressbar2.setvisibility(view.gone);           if (checkbox1.ischecked() && checkbox2.ischecked()) {             progressbar2.setvisibility(view.visible);          } else if (checkbox1.ischecked()) {             progressbar1.setvisibility(view.visible);          } 

i have implemented same requirement in application. followed below process.

since created sharedpreferences, in target activity use below.

sharedpreferences setprefsd=preferencemanager.getdefaultsharedpreferences(getapplicationcontext()); 

now boolean show below:

setprefsd.getboolean(key,value)   //key 1 have used while declaring 

let me know how goes

edit--------------------------------------------------------------------------------

change key key should string value , make ischecked static access activity

to put value in shared preferences

  editor.getboolean("key", ischecked); 

to retrive value

setprefsd.getboolean("key", ischecked)

edit2------------------------------------------------------ change share preferences insertion below.

public void putbooleaninpreferences(boolean ischecked,string key){         sharedpreferences sharedpreferences =preferencemanager.getdefaultsharedpreferences(getapplicationcontext());         sharedpreferences.editor editor = sharedpreferences.edit();         editor.putboolean("key", ischecked);         editor.commit();              }
