Radio OK Button Click

Question

How to get value from selected RadioButton when I click OK button? I want to work RadioButton function when I click OK button. NOT isChecked() function. This is my Custom RadioButton Dialog Code.

txt_language.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                final Dialog dialog = new Dialog(context);
                dialog.setContentView(R.layout.custom_language_dialog);
                tha = (RadioButton) dialog.findViewById(R.id.tha);
                en = (RadioButton) dialog.findViewById(R.id.en);
                btnOK = (Button) dialog.findViewById(R.id.btn_ok);
                if (tha.isChecked()) {
                    StoreUtil.getInstance().saveTo("languages", "tha");
                    closeAllActivities();
                }
                if (en.isChecked()) {
                    StoreUtil.getInstance().saveTo("languages", "en");
                    closeAllActivities();
                }
               // btnOK.setOnClickListener(this);
                dialog.show();
            }
        });
