Question

Create a mobile application using Android studio, for cinema tickets reservation. The application will be used by the customers to book cinema tickets. Only users of 15 years old and above are allowed to book cinema tickets for a particular film. The user can book more than one ticket where ticket prices vary between 20 and 50 AED. Your app contains tree Activities. The first activity is a launching activity containing a logo and a button start. When the user press the “Start” button the second activity will appear. The second activity is composed of three Editexts and a button; the name of the user, the user age, and the movie title the button “Reserve” is used to move to the third activity. In the third activity contains a TextView displaying the user name and the movie title, two EditTexts : Price of a ticket and the number of tickets, a button “Calculate Total” used to calculate and to confirm the reservation. First activity: 1. There should be an ImageView to display the logo of the app (Choose any icon). 2. There should be a button “Start”, when the user press this button he should be able to move to the second activity. Second activity: 1. There should be an Editext field for user to enter his/her name; this Editext must not be left empty. 2. There should be an Editext field for user to enter a valid value of his/her age. Appropriate keyboard must be displayed accordingly for the user input. The user age must be 15 and above. The Editext field relative to the user age must not be left empty. 3. There should be an Editext field for user to enter the movie title. For example Avatar, Matrix, Batman, etc. The EdiText field relative to the movie title must not be left empty. 4. There should be a button field “Reserve” for user to move to the third activity. User should be able to pass the user name and the movie title from the second activity to the third activity, which will be displayed as a textbox on the top of the third activity. Third activity: 5. There should be an EditText field for user to enter the price of a single ticket. Ticket prices vary between 20 and 50 AED, this Editext field must not be left empty. 6. User should be able to enter in an EditText how many tickets he/she is booking. Appropriate keyboard must be displayed accordingly for the user input. The user can reserve minimum 1 and maximum 10 tickets at a time.
