1. Create a new color resource to be used as the background for the data entry part of the MainActivity. Search on the web for the color and associated Android color code (color codes always start with a # symbol), and add it to the color. xml file. Set the background of the data entry part of the layout to that color resource. 2. Make the navigation work for all activities in the app. Copy the navigation bar XML code to the layout associated with each activity. Copy the Java code that makes the buttons work to the Java file associated with each activity. You will have to modify that code to reference the activity it is in, rather than MainActivity. Add code to disable the ImageButton associated with the activity that is displayed.
3. Modify the DatePickerDialog layout so that the Cancel/OK buttons are centered. Hint: You'll have to use the gravity attribute in the LinearLayout.
4. Create project called ContractorCalculator. The main activity layout should contain two Edit Texts, one button, and eight Text Views.
