Android自帶CalendarView類實現日歷視圖

文章由來：學習一下日歷控件的實現，Android3.0以下的版本請查閱其他文章。

---

 

本文主要是介紹Android日歷視圖控件CalendarView相關的內容，然后在后面會給出一個簡單的Demo。

 

CalendarView繼承自FrameLayout

其他文章都引用的類似的java代碼示例如下:

 

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();
    }
}

 

這部分代碼的工作主要在於加載layout，CalendarView被使用的時候有一些默認值，這里對默認值做了一點點改動，對界面進行美化。

 

xml代碼中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>

 

實現的效果圖是這樣的：

 

 

 

 

以上代碼就引出了使用到了CalendarView類的屬性設置，看看在設置是用得較多的代碼：

 一般常用的方法摘借（非本人翻譯，感謝翻譯的朋友們）：

 

long getDate();  //獲取從1970年，1月1日，0點0分0秒到現在的毫秒數，因為返回是long型最終只能截止到2038年

    int getFirstDayOfWeek();  //獲取當天是本周的第幾天，Android123提示返回的定義在java.util.Calendar類中，比如Calendar.Monday為星期一，定義值為2。
     
    long getMaxDate();  //獲取CalendarView支持1970年到那天的最大天數
     
    long getMinDate(); //獲取CalendarView支持1970年到那天的最小天數
     
    boolean getShowWeekNumber();  //獲取是否顯示星期號
     
    boolean isEnabled();  //是否顯示本日歷視圖
     
    public void setDate(long date, boolean animate, boolean center); //設置選擇日期到1970年的描述
     
    void setDate(long date); //設置選擇的日期描述到1970年
     
    void setEnabled(boolean enabled); //設置是否啟用視圖
     
    void setFirstDayOfWeek(int firstDayOfWeek);  //設置本周起始天數
     
    void setMaxDate(long maxDate); 
     
    void setMinDate(long minDate); 
     
    void setOnDateChangeListener(CalendarView.OnDateChangeListener listener);   //日歷視圖修改的接口，這個介紹看下面。
     
    void setShowWeekNumber(boolean showWeekNumber); //設置是否顯示周號
