Chale solo tomar la foto? Eso lo hicimos en clase. Pero bueno.


Utilizar la capacidad de AndroidStudio y sus APIS para obtener el control y uso de la cámara, logrando que el usuario tome una
fotografía y se muestre en la misma pantalla, después de tomarla.

### Funcionamiento :new_moon_with_face:

Haciendo uso de un botón y de algo de código, podemos activar la cámara al presionar dicho botón, lo que nos permitirá tomar una
foto; si nos gusta, podremos mostrarla en el dispositivo, de lo contrario, tomar otra hasta que sea de nuestro agrado.
En un principio se muestra el botón en la parte superior, acompañado de un ImageView "Dummie" que será reemplazado posteriormente
con la foto que nostros eligamos poner, como se muestra a continuación.

<p align="center">
<img src="/images/Vista1.jpg" alt="Vista 1" width="200"/>
</p>

Aquí podemos apreciar la imagen dummie que será reemplazada por la foto que tomemos. A continuación se muestra como la foto tomada
por la cámara remplaza el dummie, y el botón permitirá tomar otra foto, si así se desea.

<p align="center">
<img src="/images/Vista2.jpg" alt="Vista 2" width="200"/>
