Usage

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'

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"/>

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);

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

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.

MonthLoader.MonthChangeListener mMonthChangeListener = new MonthLoader.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;
    }
};
