Fragment Actions Show Posts and Create Post Activity

Create_Posts.java

To post something you need to create an activity from where you can send data to server however you can do the same from
your fragment but if you want to show posts in fragment, you have to do so.
Here I have used Volley Post Request so you should add Volley Libraray
