Android-CalendarView

normal mode

record mode

Support API LEVEL >= 7.

Including In Your Project

Gradle

Add the following code in the build.gradle of your module.

dependencies {
    compile 'cn.zhikaizhang.calendar:library:1.0.1'
}

Download the source code

You can also download the source code of the project and import the library module into your project as a module so that you can modify the source code.

Usage

For a working implementation of this project see the sample/ folder.

Step1. Include one of the widgets in your xml. You can set the mode 0 for the normal mode and 1 for the record mode. You can also specify the mode in your java code.

<cn.zhikaizhang.calendarview.CalendarView
        android:id="@+id/calendarView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:mode="0">
</cn.zhikaizhang.calendarview.CalendarView>

Step2. Refresh the CalendarView. You will use refresh0() for the normal calendar mode and refresh1() for the record mode.

calendarView.setMode(0);
//refresh the CalendarView with new values of year and month
calendarView.refresh0(year, month);

calendarView.setMode(1);
//simulate to get data
int days = calendarView.daysOfCurrentMonth();
boolean data[] = new boolean[days+1];
int today = Calendar.getInstance().get(Calendar.DAY_OF_MONTH);
for(int i = 1; i <= days; i++){
    if(i <= today){
        data[i] = (Math.random() > 0.5);
    }else{
        data[i] = false;
    }
}
calendarView.refresh1(data);

Step3. Set the appearance you like. You can set the language to English or Chinese. You can also modify the color and size of the text.

/**
 * modify the language of head of the calendar
 * legal values of style : 0 - 3
 * 0, 1, 2 : Chinese, 3 : English
 */
calendarView.setWeekTextStyle(style);

//set the text color of the head
calendarView.setWeekTextColor(Color.BLACK);

/**
 * set the scale of text size of the head
 * legal values : 0.0f - 1.0f
 */
calendarView.setWeekTextSizeScale(0.5f);

//set the text color of the calendar cell
calendarView.setCalendarTextColor(Color.BLACK);

/**
 * set the scale of text size of the calendar cell
 * legal values : 0.0f - 1.0f
 */
calendarView.setTextSizeScale(0.5f);

/**
 * set the color of the text of selected day
 */
calendarView.setSelectedDayTextColor(Color.WHITE);

/**
 * set the color of the background of selected day
 */
calendarView.setSelectedDayBgColor(Color.rgb(124, 180, 246));

/**
 * set the color of the background of today
 */
calendarView.setTodayBgColor(Color.rgb(124, 180, 246));

Step4. Implement the callback. Set the OnRefreshListener to do what you want after you refresh the calendar and set the OnItemClickListener to do what you want after you click a day.

calendarView.setOnRefreshListener(new ICalendarView.OnRefreshListener() {
    @Override
    public void onRefresh() {
        yearMonthTextView.setText(getYearMonthText(calendarView.getYear(), calendarView.getMonth()));
    }
});

calendarView.setOnItemClickListener(new ICalendarView.OnItemClickListener() {
    @Override
    public void onItemClick(int day) {
        int year = calendarView.getYear();
        int month = calendarView.getMonth();
        Toast.makeText(Demo0.this, year + "-" + month + "-" + day, Toast.LENGTH_SHORT).show();
    }
});
