Question

pleae no hand write and make sure to folow the instroction at the end

Build “Date Picker” in Android studio. It should allow you to select day, month and year through its interface after the click of a button “PICK DATE” and then display it in a text view. The following screenshots show the final output.

Instructions:

You can build the date picker dialog as shown in chapter 4, or you can directly use the DatePickerDialog class provided in Android. To use this, you need to read extra resources over the Web.

Explanation / Answer

Created everything as per your requirements. Created an Android app with the name Tariq Al Momatten and an activity called TariqAlMomattenMobileApplication.java with the xml layout file activity_tariq_al_momatten_mobile_application.xml. Created a button, a DatePickerDialog and a TextView. When the button is clicked, date picker dialog will popup and when the user selects a date, it’ll be displayed in the textview. I’m attaching the Activity java file, xml layout file and screenshots. You may change the package name accordingly when you run the code. Thanks
