Detail Screen Requirements :

Ensure both section labels $($Dream and Entries$)$ have the same style.

Include a $16$dp margin surrounding the entire interface $($apply this to the root LinearLayout$).$

Align the checkboxes on the same horizontal line.

Spread the checkboxes all the way flush to the left$/$right of the section.

Allow sufficient room for all five buttons to be displayed in each orientation.

Set all buttons to be disabled in the layout.

Use the following view component ID values:

title$\_$text,last$\_$updated$\_$text,fulfilled$\_$checkbox

deferred$\_$checkbox,entry$\_0\_$button,entry$\_1\_$button

entry$\_2\_$button,entry$\_3\_$button,entry$\_4\_$button

Specific to the landscape orientation only:

The Dream section and Entries section must have exactly equal widths.

Include a $16$dp width space between the two sections. Detail Screen Appearance :

Ensure that all $5$ dream entry buttons can fit entirely on the screen $$ in both portrait and landscape modes $$ on a Pixel $4$ device.

Select a unique button color for each entry kind.

Don't use the same color combinations as shown above

Ensure the reflection text is displayed in mixed case $($not all caps$).$

Display all other entry kinds as the string representation of the kind.

Populate the buttons starting from entry$\_0\_$button at the top and work down.

Set the visibility of any buttons without associated entries to View.GONE.

For the last updated date, use the format function of android.text.format.DateFormat.

Double$-$check the imports, as there are several other DateFormat classes available in other packages

Use the following format string:

'Last updated' yyyy$-$MM$-$dd $\text{'}$at$\text{'}$ hh:mm:ss A

Note that the above format string can just be hard$-$coded, rather than stored as a string resource, since we haven't quite yet covered how to manage general purpose string resources.

Detail Screen Behavior :

Checkbox behavior $-$ Checking either checkbox must:

Disable the other checkbox, so at most only one may be checked.

Append a new entry of the proper kind $($Deferred or Fulfilled$)$ to the end of the entry list.

Unchecking either checkbox must:

Enable the other checkbox, so both checkboxes are enabled only when neither is checked.

Remove the entry of the proper kind $($Deferred or Fulfilled$)$ from the list.

Any user changes $($dream title and$/$or checkbox state$)$ must update the Dream object in the view model.

The entire system state must persist across a screen rotation

The last updated timestamp shouldn't be changed by the code in this project.

This value gets set once, when the DreamDetailViewModel instantiates the Dream object, and remains the same until the app is closed.
