Je travaille sur une application Android (v3.0) qui a une exigence de mimer la mise en page de calendrier hebdomadaire trouvé sur Google Agenda:
Les événements sont basés sur les demandes externes via l'API Google Calendar (je l'ai déjà ce travail partiel). Utilisation de l'API, je peux obtenir une liste des événements de la semaine, chaque événement ayant un début et de fin et datetime. Je voudrais utiliser ces données pour afficher les événements programmés aux utilisateurs de l'application dans une vue similaire à celle ci-dessus.
Voici ce que j'ai à ce jour:
Le XML apparaît ci-dessous:

Mon approche était de faire 40dp égale à 1 heure de temps. Ainsi, chaque fois que je voudrais ajouter un événement qui a une durée de 1,5 heures, je ferai un bouton 60dp que je placerai à l'endroit exact que le temps commence (00 heures = 0DP du haut, 13 heures = 40dp du haut , 14 heures = 80d à partir du haut, etc.).
Mes questions sont les suivantes:
- Y at-il une meilleure façon de le faire?
- Comment puis-je convertir mon XML pour être vue autonome qui pourrait être ajouté à tout projet Android? (Je l'intention de faire peut-être un billet de blog sur le produit final)
Merci!
La solution
I ended up following a similar approach to my original post. I created a scroll view with a linear layout inside of it. I then added seven relative layouts to the linear layout. Each of the relative layouts is one day. I made sure that the heights of these layouts were equal to the number of minutes in a day. This would make 1 hour = 60 minutes = 60 dp, which makes measuring the heights of events easier. For events, I created a custom view that can display the start and end time of the event, as well as the event's title. The events were added to the relative layouts with a layout_marginTop property, whose value equaled to the starting time of the event in minutes from the beginning of the day. This seemed to work just fine.
Here's a preview of what it ended up looking like:
Here's the XML layout: http://pastebin.com/jT4wQxeb
The code is too long to fit into the answer.
Note: calendar_zebra is simply a 60 * 24 = 1440dp high layout with 1 dp high horizontal Views with a solid gray background placed every 60dp. Each represents a marker for an hour of time.
Autres conseils
1. Here is what I figure out from the source of Calendar
It creates a customized View(DayView for the agenda in a day) for the whole layout in your xml.
Then it draw the canvas using rectangle and text like what you can see in the app when the onDraw() is called.
The View implements OnClickListener and OnLongClickListener for the event. When you click on the canvas, it transfers your click position to the Event with corresponding Date and Time(so it calculated a lots of related size for event, margin, whole day event when the override onSizeChanged() is called), then starts the Activity if such Event exists, otherwise creates a new Event.
2.You need to create a Class extends View, say DayView, then you should add this into attrs.xml
<resources>
<declare-styleable name="DayView">
</declare-styleable>
</resources>
Then you can use it as a xml tag in layout with your package name. like here:
<xxxxxxx.DayView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:id="@id/ui_schedule_dayview">
Here you can find the sample to do so
