Review Exercises

1. Explain what these items are:
   

   setContentView  match_parent  wrap_content  id  dp  sp
   LinearLayout  ConstraintLayout  layout_ margin  padding
   strings.xml  SeekBar  onLongClick  MyView  onTouch  
   SQLiteOpenHelper  manifest 
   

   We have been using these items all quarter, look them up in the class notes and examples.
2. How does a user interface constructed with Jetpack Compose differ from a traditional Android app?
   Answer: the biggest difference is that Jetpack Compose does not use a layout file, but does everything in the activity file, including the user interface. Android studio has a preview option which displays the user interface as the code is being written.
   
   In one sense, Jetpack Compose is similar to using LinearLayout because components stack vertically or horizontally by putting them in Column or Row components.
