name: inverse layout: true class: center, middle, inverse --- # Week 2 and Practice Quiz 2 Review Lauren Bricker CSE 340 Spring 23 --- name: normal layout: true class: --- # Layout Wireframe vs Interactor Hierarchy There was some confusion about what a Layout Wireframe is vs an Interactor Hierarchy. - In a **Layout Wireframe** you should graphically specify the positioning of the interactors - Must include the type of Layout, including for specifing horizontal or vertical for `LinearLayout` - You could also show where there are margins, constraints, etc - An **Interactor Hierarchy** graphically depicts the parent child relationships between the interactors used to render the app. You will need to to know this for Layout part 4. --- # Layout Wireframe A **Layout Wireframe** you should graphically specify the positioning of the interactors Interface mockup | Layout Wireframe -- | --  |  --- # Interactor Hierarchy An **Interactor Hierarchy** graphically depicts the parent child relationships between the interactors used to render the app. Interface mockup | Interactor Hierarchy -- | --  |  --- # Interactor Hierarchy You could depict this hierarchy also as an "outline" view .left-column[  ] .right-column[ - ConstraintLayout (could also be LinearLayout (vertical)) - TextView - ImageView - LinearLayout (horizontal) (could also be a ConstraintLayout) - Button - Button - Button ] --- # Spot the Heron activity .left-column-half[  ] .right-column-half[ Fist to Five: How comfortable did you feel with creating this interface in Android Studio? - Fist/0 - I really didn't feel comfortable at all - Five - I really really felt comfortable, could do this in my sleep ] --- # Animation .left-column[  ] .right-column[ The Zoom app has incorporated Animation in the interface as seen on the left. What pacing function do you think they are using? ] -- count: false .right-column[ Pacing functions seen: - Bounce (at the end of the scroll) or Overshoots - Slow in (transition from Meetings to Schedule a meeting screen)/Slow out (some specifically said AccelerateDecelerateInterpolator) ] --- # Animation Design Tips .left-column[  ] .right-column[ Pick an Animation Design Tip and justify whether the interface programmer for this app met or violated that tip. 1. Used sparingly and understandingly, animation can enhance the interface … otherwise can distract! 2. Need to mimic real world 3. Observing motion tells us about size, weight, rigidity 4. No abrupt changes in velocity! 5. Think about accessibility. ] --- # Animation Design Tips .left-column[  ] .right-column[ Pick an Animation Design Tip and justify whether the interface programmer for this app met or violated that tip. 1. Used sparingly and understandingly, animation can enhance the interface … otherwise can distract! - Met: if justified: The animations do not distract from the function of the app - Violated: if justified: some might say the animation is superfluous 2.
