title: Android trouble in proceeding the activity
body: <p>I am new to Android  development. I have seen a few tutorials and some textual references also. So I have a basic idea of Android. I am currently facing a problem while writing the JAVA code. I am unable to grasp the concept of what should be my next step while writing the code. Eg. I want to create an application for online attendance. I decided to have a text box for roll number and a 'submit' button to submit the attendance. Now in my Main.java file , after creating a button object, I am not following what my next step should be. 
  Similar situations arise when I try to make a jump from one page to another page.</p>
