How to make the Radio Button appear checked if the database is updated Android Studiop

Question

I’m making an app with questions and answers, I have a radiogroup, a textview and 3 buttons: confirm, next and back.

I am trying to get once the question is answered, when returning in that question the answer is shown in the radiogroup selections.

But when I return the question the condition not to let select a new answer is applied, but to show the radio button checked not.

 public void onClick(View v) {
    switch (v.getId()){

        case R.id.button_next:

            int_lei=Integer.parseInt(temp_lei);
            int_lei ++;
            temp_lei= String.valueOf(int_lei);

            AdminSQLiteOpenHelper admin = new AdminSQLiteOpenHelper(this, "admin", null, 1);
            SQLiteDatabase BasedeDados = admin.getWritableDatabase();

            Cursor consulta1 = BasedeDados.rawQuery("select * from Escriturario where Lei="+temp_lei, null);
            consulta1.moveToFirst();

            Pergunta.setText(consulta1.getString(1));
            rb1.setText(consulta1.getString(2));
            rb2.setText(consulta1.getString(3));
            rb3.setText(consulta1.getString(4));
            rb4.setText(consulta1.getString(5));
            rb5.setText(consulta1.getString(6));

            feito = consulta1.getInt(8);

            if(feito != 6){
                rg.check(feito);
                rb1.setClickable(false);
                rb2.setClickable(false);
                rb3.setClickable(false);
                rb4.setClickable(false);
                rb5.setClickable(false);
                bt3.setClickable(false);

            }
            else{
                rg.clearCheck();
                rb1.setClickable(true);

                bt3.setClickable(true);
                }

            break;

        case R.id.button_back:
            int_lei=Integer.parseInt(temp_lei);
            int_lei --;
            temp_lei= String.valueOf(int_lei);

            if(1 <= int_lei) {

                admin = new AdminSQLiteOpenHelper(this, "admin", null, 1);
                BasedeDados = admin.getWritableDatabase();

                consulta1 = BasedeDados.rawQuery("select * from Escriturario where Lei=" + temp_lei, null);

            break;
        case R.id.button_validate:

                        (this, "admin", null, 1);
            BasedeDados = admin.getWritableDatabase();

            consulta1.moveToPosition(int_lei);
            resposta = consulta1.getInt(7);
            int int_resposta = -1;

            switch(rg.getCheckedRadioButtonId()){
            case R.id.rb1:

                    }
                    if (resposta != int_resposta) {
                        Toast.makeText(this, "Resposta incorreta", Toast.LENGTH_LONG).show();
                    }
                    else {
                        Toast.makeText(this, "Selecione uma resposta", Toast.LENGTH_SHORT).show();
                    }
                    rb1.setClickable(false);
                    rb2.setClickable(false);
                    rb3.setClickable(false);
                    rb4.setClickable(false);
                    rb5.setClickable(false);
                    bt3.setClickable(false);              
    }

Could help me get to the expected behavior.
