Usage

1. Import the library into your project.

• Grab via maven

  <dependency>
    <groupId>com.github.alamkanak</groupId>
    <artifactId>android-week-view</artifactId>
    <version>1.2.3</version>
    <type>aar</type>
  </dependency>

• Grab via gradle

  compile 'com.github.alamkanak:android-week-view:1.2.3'

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;
       }
   };

Interfaces

Use the following interfaces according to your need.

• mWeekView.setMonthChangeListener() to provide events to the calendar
• 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
