Can Not Save The State Of Checkbox In Android

I am developing an application. There are many checkbox in one page. I want to save the state of CheckBox when I exit page. I use SharedPreferrences to save. The code is like this:

Solution 1:

You are saving vallues but you have to restore them you your activity is started like this :

SharedPreferencesprefs= getSharedPreferences("syllabus", 0);
checkbox1.setChecked(prefs.getBoolean("cbx1_ischecked" ,false));
checkbox2.setChecked(prefs.getBoolean("cbx2_ischecked" ,false));

Solution 2:

try this

boolean check1,check2;
 checkbox1.setOnCheckedChangeListener(newOnCheckedChangeListener(){
 publicvoidonCheckedChanged(CompoundButton arg0, boolean isChecked) {
 // TODO Auto-generated method stub
  check1=isChecked;

 }
});

checkbox2.setOnCheckedChangeListener(newOnCheckedChangeListener(){
publicvoidonCheckedChanged(CompoundButton arg0, boolean isChecked) {
// TODO Auto-generated method stub
 check2=isChecked;

}

}); 

//store boolean only once when you leave the activityEditoreditor= getSharedPreferences("syllabus", 0).edit();
 editor.putBoolean("cbx1_ischecked", check1);
 editor.putBoolean("cbx2_ischecked", check2);
 editor.commit();


 In onCreate()SharedPreferencesprefs= getSharedPreferences("syllabus", 0);
  checkbox1.setChecked(prefs.getBoolean("cbx1_ischecked" ,false));
  checkbox2.setChecked(prefs.getBoolean("cbx2_ischecked" ,false));
