You must first fetch the XML element,

 final Button btnResposta1 = (Button) findViewById(R.id.btnResposta1);
 final Button btnResposta2 = (Button) findViewById(R.id.btnResposta2);

After implementing onClickListener

private View.OnClickListener onClickListener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //faca um cast para Button
            Button botao = (Button)view;
            //pegue o texto
            String respostaBotao = botao .getText().toString();
            switch (view.getId()){
                case (R.id.btnResposta1):
                    //codigo caso clicar resposta 1
                    break;
                case (R.id.btnResposta2):
                    //codigo caso clicar resposta 2
                    break;
        }
}

then link to the button listener.

btnResposta1.setOnClickListener(onClickListener);
btnResposta2.setOnClickListener(onClickListener);

I hope to have helped!
