Can't use boolean variable in inner class

I have a few checkboxes within a dialog window. I want to save the checkboxes, after the customer confirmed with a button, that he want to save those settings. I tried to realize the code above, I cant find a way where I have to declerate the boolean's check1 and check2. Hope anyone can help me, if you need more information, please ask.

     protected void onCreate(Bundle savedInstanceState) {

      // ....

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

     // ...

     checkbox1.setOnCheckedChangeListener(new OnCheckedChangeListener(){
     public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
     // TODO Auto-generated method stub
      check1=isChecked;

     }
    });

    checkbox2.setOnCheckedChangeListener(new OnCheckedChangeListener(){
    public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
    // TODO Auto-generated method stub
     check2=isChecked;

    }

    }); 

      buttonSave.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                     Editor editor = getSharedPreferences("testSave", 0).edit();
                     editor.putBoolean("cbx1_ischecked", check1);
                     editor.putBoolean("cbx2_ischecked", check2);
                     editor.commit();
                    }
                });

});
