Usage

1. Import the library into your project.

• Grab via maven

  <dependency>
    <groupId>com.github.alamkanak</groupId>
    <artifactId>android-week-view</artifactId>
    <version>1.2.6</version>
    <type>aar</type>
  </dependency>

• Grab via gradle

  compile 'com.github.alamkanak:android-week-view:1.2.6'

2. Add WeekView in your xml layout.

   <com.alamkanak.weekview.WeekView
           android:id="@+id/weekView"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           app:eventTextColor="@android:color/white"
           app:textSize="12sp"
           app:hourHeight="60dp"
           app:headerColumnPadding="8dp"
           app:headerColumnTextColor="#8f000000"
           app:headerRowPadding="12dp"
           app:columnGap="8dp"
           app:noOfVisibleDays="3"
           app:headerRowBackgroundColor="#ffefefef"
           app:dayBackgroundColor="#05000000"
           app:todayBackgroundColor="#1848adff"
           app:headerColumnBackground="#ffffffff"/>

3. Write the following code in your java file.

   // Get a reference for the week view in the layout.
   mWeekView = (WeekView) findViewById(R.id.weekView);
   
   // Set an action when any event is clicked.
   mWeekView.setOnEventClickListener(mEventClickListener);
   
   // The week view has infinite scrolling horizontally. We have to provide the events of a
   // month every time the month changes on the week view.
   mWeekView.setMonthChangeListener(mMonthChangeListener);
   
   // Set long press listener for events.
   mWeekView.setEventLongPressListener(mEventLongPressListener);

4. Implement WeekView.MonthChangeListener, WeekView.EventClickListener, WeekView.EventLongPressListener according to your need.

5. Provide the events for the WeekView in WeekView.MonthChangeListener.onMonthChange() callback. Please remember that the calendar pre-loads events of three consecutive months to enable lag-free scrolling.

   WeekView.MonthChangeListener mMonthChangeListener = new WeekView.MonthChangeListener() {
       @Override
       public List<WeekViewEvent> onMonthChange(int newYear, int newMonth) {
           // Populate the week view with some events.
           List<WeekViewEvent> events = getEvents(newYear, newMonth);
           return events;
       }
   };

Customization

You can customize the look of the WeekView in xml. Use the following attributes in xml. All these attributes also have getters and setters to enable you to change the style dynamically.

• allDayEventHeight
• columnGap
• dayBackgroundColor
• dayNameLength
• eventMarginVertical
• eventPadding
• eventTextColor
• eventTextSize
• firstDayOfWeek
• zoomFocusPoint The focused point (percentage of the view height) where the week view is zoomed around. This point will not move while zooming. You can declare it as a fraction app:focusPoint="30%" and if is not declared the top of the view is used.
• zoomFocusPointEnabled If you set this to false the zoomFocusPoint won't take effect any more while zooming. The zoom will always be focused at the center of your gesture.
• headerColumnBackground
• headerColumnPadding
• headerColumnTextColor
• headerRowBackgroundColor
• headerRowPadding
• hourHeight
• hourSeparatorColor
• hourSeparatorHeight
• noOfVisibleDays
• overlappingEventGap
• textSize
• todayBackgroundColor
• todayHeaderTextColor
• showDistinctPastFutureColor
• futureBackgroundColor
• pastBackgroundColor
• showDistinctWeekendColor
• futureWeekendBackgroundColor
• pastWeekendBackgroundColor
• showNowLine
• nowLineColor
• nowLineThickness
• scrollDuration

Interfaces

Use the following interfaces according to your need.

• mWeekView.setWeekViewLoader() to provide events to the calendar
• mWeekView.setMonthChangeListener() to provide events to the calendar by months
• mWeekView.setOnEventClickListener() to get a callback when an event is clicked
• mWeekView.setEventLongPressListener() to get a callback when an event is long pressed
• mWeekView.setEmptyViewClickListener() to get a callback when any empty space is clicked
• mWeekView.setEmptyViewLongPressListener() to get a callback when any empty space is long pressed
• mWeekView.setDateTimeInterpreter() to set your own labels for the calendar header row and header column
• mWeekView.setScrollListener() to get an event every time the first visible day has changed

Sample

There is also a sample app to get you started.

To do

• Add event touch feedback selector
• Show events that expand multiple days properly
