# Material-Calendar-View

Material-Calendar-View is a simple and customizable calendar widget for Android based on Material Design. The widget has two funcionalities: a date picker to select dates (available as an XML widget and a dialog) and a classic calendar. The date picker can work either as a single day picker, many days picker or range picker.

We described a simple usage of the component [in this article](http://applandeo.com/blog/material-calendar-view-customized-calendar-widget-android/).

## How to use?

Make sure you are using Java 8 in your project. If not, add below code to **build.gradle** file:
```
android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
```

Make sure you have defined the **mavenCentral()** repository in project's **build.gradle** file:
```
allprojects {
    repositories {
        mavenCentral()
    }
}
```

Add the dependency to module's **build.gradle** file:
```
dependencies {
    implementation 'com.applandeo:material-calendar-view:1.9.2'
}
```

To your **XML layout** file add:
```xml
<com.applandeo.materialcalendarview.CalendarView
    android:id="@+id/calendarView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
```

### Adding events with icons:
```java
List<CalendarDay> calendarDays = new ArrayList<>();

Calendar calendar = Calendar.getInstance();
CalendarDay calendarDay = new CalendarDay(calendar);
calendarDay.setImageResource(R.drawable.sample_icon);
calendarDays.add(event);

//or if you want to specify event label color
calendarDay.setLabelColor(Color.parseColor("#228B22"));
calendarDays.add(calendarDay);

CalendarView calendarView = (CalendarView) findViewById(R.id.calendarView);
calendarView.setCalendarDays(calendarDays);
```

### How to create icons?
#### Drawable with text:
You can use our utils method to create Drawable with text
```java
CalendarUtils.getDrawableText(Context context, String text, Typeface typeface, int color, int size);
````
#### Dots indicator:
Take a look at [sample_three_icons.xml](https://github.com/Applandeo/Material-Calendar-View/blob/master/sample/src/main/res/drawable/sample_three_icons.xml) and adjust it to your project

### Clicks handling:
```java
calendarView.setOnCalendarDayClickListener(new OnCalendarDayClickListener() {
    @Override
    public void onDayClick(CalendarDay calendarDay) {
        Calendar clickedDayCalendar = calendarDay.getCalendar();    
    }
});
```

...or long click:
```java
calendarView.setOnCalendarDayLongClickListener(new OnCalendarDayLongClickListener() {
    @Override
    public void onDayLongClick(CalendarDay calendarDay) {
        Calendar clickedDayCalendar = calendarDay.getCalendar();
    }
});
```

### Getting a selected days in the picker mode:
If you want to get all selected days, especially if you use multi date or range picker you should use the following code:
```java
List<Calendar> selectedDates = calendarView.getSelectedDates();
```
...or if you want to get the first selected day, for example in case of using single date picker, you can use:
```java
Calendar selectedDate = calendarView.getFirstSelectedDate();
```

### Setting a current date:
```java
Calendar calendar = Calendar.getInstance();
calendar.set(2019, 7, 5);

calendarView.setDate(calendar);
```

### Setting minumum and maximum dates:
```java
Calendar min = Calendar.getInstance();
Calendar max = Calendar.getInstance();

calendarView.setMinimumDate(min);
calendarView.setMaximumDate(max);
```

### Setting disabled dates:
```java
List<Calendar> calendars = new ArrayList<>();
calendarView.setDisabledDays(calendars);
```

### Setting highlighted days:
```java
List<Calendar> calendars = new ArrayList<>();
calendarView.setHighlightedDays(calendars);
```

### Setting selected dates:
```java
List<Calendar> calendars = new ArrayList<>();
calendarView.setSelectedDates(calendars);
```

...or if you want to remove selected dates:

```java
calendarView.clearSelectedDays();
```

#### Caution!
* Don't pass more than one calendar object to method above if your calendar type is `CalendarView.ONE_DAY_PICKER`.
* If your calendar type is `CalendarView.RANGE_PICKER` you have to pass full dates range. To get it you can use our utils method `CalendarUtils.getDatesRange(Calendar firstDay, Calendar lastDay)`.

### Previous and forward page change listeners:
```java
calendarView.setOnPreviousPageChangeListener(new OnCalendarPageChangeListener() {
    @Override
    public void onChange() {
        ...
    }
});

calendarView.setOnForwardPageChangeListener(new OnCalendarPageChangeListener() {
    @Override
    public void onChange() {
        ...
    }
});
```

## Customization
If you want to use calendar in the picker mode, you have to use the following tags:
* ```app:type="one_day_picker"```
* ```app:type="many_days_picker"```
* ```app:type="range_picker"```

If you want to display event icons in the picker mode, add:
* ```app:eventsEnabled="true"```

#### Colors customization:
* Header color: ```app:headerColor="[color]"```
* Header label color: ```app:headerLabelColor="[color]"```
* Previous button image resource: ```app:previousButtonSrc="[drawable]"```
* Forward button image resource: ```app:forwardButtonSrc="[drawable]"```
* Abbreviations bar color: ```app:abbreviationsBarColor="[color]"```
* Abbreviations labels color: ```app:abbreviationsLabelsColor="[color]"```
* Calendar pages color: ```app:pagesColor="[color]"```
* Selection color in picker mode: ```app:selectionColor="[color]"```
* Selection label color in picker mode: ```app:selectionLabelColor="[color]"```
* Days labels color: ```app:daysLabelsColor="[color]"```
* Color of visible days labels from previous and next month page: ```app:anotherMonthsDaysLabelsColor="[color]"```
* Disabled days labels color: ```app:disabledDaysLabelsColor="[color]"```
* Highlighted days labels color: ```app:highlightedDaysLabelsColor="[color]"```
* Today label color: ```app:todayLabelColor="[color]"```

...or in code:

```java
CalendarView calendarView = (CalendarView) findViewById(R.id.calendarView);
calendarView.setHeaderColor([color]);
calendarView.setHeaderLabelColor([color]);
calendarView.setForwardButtonImage([drawable]);
calendarView.setPreviousButtonImage([drawable]);
```

#### Custom view for days cells:
To use custom view for calendar cells create XML file (like in example below) and set it using `setCalendarDayLayout(@LayoutRes layout: Int)` method. XML file must contain TextView with id `dayLabel` and can contain ImageView with id `dayIcon`. Do not set colors or textStyle here, it will be overwritten.
```xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/selectableItemBackgroundBorderless"
    android:orientation="vertical">

    <!--REQUIRED-->
    <TextView
        android:id="@+id/dayLabel"
        ... />

    <!--CAN BE SKIPPED-->
    <androidx.appcompat.widget.AppCompatImageView
        android:id="@+id/dayIcon"
        ... />

</LinearLayout>
```

#### Customization of specific cells:
If you want to customize specyfic cells create list of `CalendarDay` objects and pass it by `setCalendarDays()` method like in example below:
```kotlin
val list = listOf(
    CalendarDay(Calendar.getInstance()).apply { 
        labelColor = [color resource]
        backgroundResource = [drawable resource]
        backgroundDrawable = [drawable]
        selectedLabelColor = [color resource]
        selectedBackgroundResource = [drawable resource]
        selectedBackgroundDrawable = [drawable]
    }
)

calendarView.setCalendarDays(list)
```

*In the future `CalendarDay` will replace `EventDay`.*

#### Customized font:
* To create font directory Right-click the res folder and go to New > Android resource directory. — The New Resource Directory window appears.
* In the Resource type list, select font, and then click OK.
* Note: The name of the resource directory must be font.
* Add your ttf or otf fonts in font folder. As an example we ad sample_font.ttf and sample_font_bold.ttf
* On a DatePickerBuilder apply ```.typefaceSrc(R.font.sample_font)``` for setting sample_font to callendar and its abbreviations.
* Optionally apply ```.todayTypefaceSrc(R.font.sample_font_bold)``` to differentiate today date font form the rest of dates in calendar view

#### Disable month swipe:
If you want to disable the swipe gesture to change the month, you have to use the following tag:
* ```app:swipeEnabled="false"```

...or in code:

```java
calendarView.setSwipeEnabled(false);
```

#### First day of a week:
If you want to change default first day of week:
* ```app:firstDayOfWeek="[day]"```

...or in code:

```java
calendarView.setFirstDayOfWeek([CalendarWeekDay]);
```
By default the first day is monday or sunday depending on user location.

#### Translations:
To translate months names, abbreviations of days, "TODAY", "OK" and "CANCEL" buttons, just add below tags to your `strings.xml` file:
```xml
<string name="material_calendar_monday">M</string>
<string name="material_calendar_tuesday">T</string>
<string name="material_calendar_wednesday">W</string>
<string name="material_calendar_thursday">T</string>
<string name="material_calendar_friday">F</string>
<string name="material_calendar_saturday">S</string>
<string name="material_calendar_sunday">S</string>

<array name="material_calendar_months_array">
    <item>January</item>
    <item>February</item>
    <item>March</item>
    <item>April</item>
    <item>May</item>
    <item>June</item>
    <item>July</item>
    <item>August</item>
    <item>September</item>
    <item>October</item>
    <item>November</item>
    <item>December</item>
</array>

<string name="material_calendar_today_button">Today</string>
<string name="material_calendar_positive_button">OK</string>
<string name="material_calendar_negative_button">Cancel</string>
```

## Date Picker Dialog
```java
DatePickerBuilder builder = new DatePickerBuilder(this, listener)
                .pickerType(CalendarView.ONE_DAY_PICKER);

DatePicker datePicker = builder.build();
datePicker.show();
```

To use another picker type replace `CalendarView.ONE_DAY_PICKER` with `CalendarView.MANY_DAYS_PICKER` or `CalendarView.RANGE_PICKER`.

#### Getting date handling:
```java
private OnSelectDateListener listener = new OnSelectDateListener() {
    @Override
    public void onSelect(List<Calendar> calendars) {
        ...
    }
};
```

#### Customization:
```java
new DatePickerBuilder(this, listener)
        .date(Calendar.getInstance()) // Initial date as Calendar object
        .minimumDate(Calendar.getInstance()) // Minimum available date
        .maximumDate(Calendar.getInstance()) // Maximum available date
