Android自带CalendarView类实现日历视图

文章由来:学习一下日历控件的实现,Android3.0以下的版本请查阅其他文章。


 

本文主要是介绍Android日历视图控件CalendarView相关的内容,然后在后面会给出一个简单的Demo。

 

CalendarView继承自FrameLayout

其他文章都引用的类似的java代码示例如下:

public class MainActivity extends Activity implements OnClickListener,        OnDateChangeListener {    private CalendarView calendarView;    private TextView tvCalendar, tvReminder, tvNote, tvMore;    private ImageView ivNext;    private ImageView ivPrevious;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        this.requestWindowFeature(Window.FEATURE_NO_TITLE);        setContentView(R.layout.activity_main);//        initData();//        initUI();    }}
View Code

 

这部分代码的工作主要在于加载layout,CalendarView被使用的时候有一些默认值,这里对默认值做了一点点改动,对界面进行美化。

 

xml代码中CalendarView部分如下:

    <LinearLayout        android:layout_width="fill_parent"        android:layout_height="match_parent"        android:layout_weight="8"        android:orientation="vertical" >        <CalendarView            android:id="@+id/calendarview"            android:layout_width="fill_parent"            android:layout_height="match_parent"            android:focusedMonthDateColor="@color/whitesmoke"            android:unfocusedMonthDateColor="@color/transparent"            android:selectedWeekBackgroundColor="@color/transparent"            android:showWeekNumber="false"            android:weekSeparatorLineColor="@color/transparent" />    </LinearLayout>
View Code

 

实现的效果图是这样的:

以上代码就引出了使用到了CalendarView类的属性设置,看看在设置是用得较多的代码:

 一般常用的方法摘借(非本人翻译,感谢翻译的朋友们):

long getDate();  //获取从1970年,1月1日,0点0分0秒到现在的毫秒数,因为返回是long型最终只能截止到2038年    int getFirstDayOfWeek();  //获取当天是本周的第几天,Android123提示返回的定义在java.util.Calendar类中,比如Calendar.Monday为星期一,定义值为2。         long getMaxDate();  //获取CalendarView支持1970年到那天的最大天数         long getMinDate(); //获取CalendarView支持1970年到那天的最小天数         boolean getShowWeekNumber();  //获取是否显示星期号         boolean isEnabled();  //是否显示本日历视图         public void setDate(long date, boolean animate, boolean center); //设置选择日期到1970年的描述         void setDate(long date); //设置选择的日期描述到1970年         void setEnabled(boolean enabled); //设置是否启用视图         void setFirstDayOfWeek(int firstDayOfWeek);  //设置本周起始天数         void setMaxDate(long maxDate);          void setMinDate(long minDate);          void setOnDateChangeListener(CalendarView.OnDateChangeListener listener);   //日历视图修改的接口,这个介绍看下面。         void setShowWeekNumber(boolean showWeekNumber); //设置是否显示周号
