Question

I used onCheckedChanged method to handle the checkboxes.Its working well when i clicked.After leaving or closing the application and when i reopening it,the checkboxes state remains disabled.I want my checkboes state as i clicked(checked/unchecked) even after closing the application and reopening it.I tried using sharedpreferences posted here to achieve it.But as i am not cleared about it,i couldn’t.

viewHolder.checkbox
                .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

                    @Override
                    public void onCheckedChanged(CompoundButton buttonView,
                            boolean isChecked) {


                        Model element = (Model) viewHolder.checkbox
                                .getTag();
                        element.setSelected(buttonView.isChecked());


   Interactivearrayadapter.this.putBooleanInPreferences(isChecked,"isChecked");
 }
  });
  }

 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;   

I used this code inside Interactivearrayadapter class since i displayed checkboxes in a list.Error shows in getpreference(string) not support to this class.

store your checkbox ischecked() flag in sharedpreferences and get that flag and show whenever you start the App next time.
