Using Java and Android Studio:

You want to design a to$-$do list application to record and set importance for your list. The application should include several screens:

$1.$ The first screen should have a text box to let you input, three buttons for the importance of low, normal, and high, and one button to finish and go to the next page.

$2.$ The second screen is a two$-$column table. One column is the list of to$-$do things, and another is the importance. Each row is one to$-$do thing. A button to add more $($or back$).$

$3.$ Tapping each to$-$do thing, the screen shows the details $($Need a back button for back the previous screen$).$
