When opening the alertDialog the result is zero, follow the code

calcular.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            String adulto = edit_adulto.getText().toString();
            String crianca = edit_crianca.getText().toString();

            dialog = new AlertDialog.Builder(MainActivity.this);
            dialog.setTitle("Resultado");                
            dialog.setMessage("O valor é: " + resultadoA);
            dialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });

            if (dia.isChecked()){

                if(!adulto.isEmpty()){
                    valorDigitadoA = Integer.parseInt(adulto);
                    resultadoA = valorDigitadoA * 15;
                    dialog.show();
                }
                if(!crianca.isEmpty()){
                    valorDigitadoC = Integer.parseInt(crianca);
                     resultadoC = (valorDigitadoC * 10);
                }
            }

Nothing appears because you are setting Dialog text with the variable ResultadoA before it has any value.

You must use the setMessage method within the condition shortly after assigning the desired value to your variable. Here's how it should look:

if(!adulto.isEmpty()){
    valorDigitadoA = Integer.parseInt(adulto);
    resultadoA = valorDigitadoA * 15;

    // aqui será mostrado a mensagem no dialogo 
    // com o valor atribuído a variável resultadoA
    dialog.setMessage("O valor é: " + resultadoA);
    dialog.show();
}
