我们在开发中会遇到使用到日历控件，下面就介绍一个自定义日历控件。
思路:
1.自定义类CalendarView继承LinearLayout，使用布局文件，显示布局。
2.使用ViewFlipper，里面添加GridView，当月的日期。
3.使用手势GestureDetector，控制ViewFlipper的滑动。

}
}
}</span>在initView中调用addGridView()。初始化显示日期的View，然后设置其适配器，然后添加到flipper.addView(gridView, 0);中
addTextToTopTextView()更改标题显示的年和月
enterNextMonth()显示下一个月日历，首先是将下个月的GridView添加到ViewFlipper中，显示下个月的信息，并且移除上个月的GridView。
enterPrevMonth():显示上一个月的日历，首先将上个月的GridView添加到ViewFlipper中，显示下个月的信息，并且移除当前月的GridView。
在MyGestureListener类中，判断是否显示上个月或者下一月信息的情况，向左滑动，显示上一个月信息，向右滑动，显示上月日历。
在gridView的setOnItemClickListener，如果点击日期，差通过接口传递出去，并且通知适配器，当前日期的颜色背景需要改变(当月的日期)。
适配器
<span style="font-family:SimSun;font-size:18px;">public CalendarAdapter(Context context, Resources rs, int jumpMonth,
int jumpYear, int year_c, int month_c, int day_c) {
this();
this.context = context;
sc = new SpecialCalendar();
lc = new LunarCalendar();
this.res = rs;
int stepYear = year_c + jumpYear;
int stepMonth = month_c + jumpMonth;
if (stepMonth > 0) {
// 往下一个月滑动
if (stepMonth % 12 == 0) {
stepYear = year_c + stepMonth / 12 - 1;
stepMonth = 12;
} else {
stepYear = year_c + stepMonth / 12;
stepMonth = stepMonth % 12;
}
} else {
// 往上一个月滑动
stepYear = year_c - 1 + stepMonth / 12;
stepMonth = stepMonth % 12 + 12;
if (stepMonth % 12 == 0) {
}
}
currentYear = String.valueOf(stepYear); // 得到当前的年份
currentMonth = String.valueOf(stepMonth); // 得到本月
// （jumpMonth为滑动的次数，每滑动一次就增加一月或减一月）
currentDay = String.valueOf(day_c); // 得到当前日期是哪天
getCalendar(Integer.parseInt(currentYear),
Integer.parseInt(currentMonth));
}
</span>通过stepMonth+系统显示的月，就可以知道要使显示yyyy年mm月了。
<span style="font-family:SimSun;font-size:18px;">private void getweek(int year, int month) {
int j = 1;
String lunarDay = "";
// 得到当前月的所有日程日期(这些日期需要标记)
for (int i = 0; i < dayNumber.length; i++) {
if (i < dayOfWeek) { // 前一个月
int temp = lastDaysOfMonth - dayOfWeek + 1;
lunarDay = lc.getLunarDate(year, month - 1, temp + i, false);
dayNumber[i] = (temp + i) + "." + lunarDay;
} else if (i < daysOfMonth + dayOfWeek) { // 本月
String day = String.valueOf(i - dayOfWeek + 1); // 得到的日期
lunarDay = lc.getLunarDate(year, month, i - dayOfWeek + 1,
false);
dayNumber[i] = i - dayOfWeek + 1 + "." + lunarDay;
// 对于当前月才去标记当前日期
if (sys_year.equals(String.valueOf(year))
&& sys_month.equals(String.valueOf(month))
&& sys_day.equals(day)) {
// 标记当前日期
colorDataPosition = i;
}
setShowYear(String.valueOf(year));
setShowMonth(String.valueOf(month));
setAnimalsYear(lc.animalsYear(year));
setLeapMonth(lc.leapMonth == 0 ? "" : String
.valueOf(lc.leapMonth));
setCyclical(lc.cyclical(year));
} else { // 下一个月
lunarDay = lc.getLunarDate(year, month + 1, j, false);
dayNumber[i] = j + "." + lunarDay;
j++;
}
}
String abc = "";
for (int i = 0; i < dayNumber.length; i++) {
abc = abc + dayNumber[i] + ":";
}
Log.d("DAYNUMBER", abc);
}</span>通过SpecialCalendar中的getWeekdayOfMonth获取当月第一天为星期几(dayOfWeek)，
显示位置:position<dayOfWeek表示前一个月的日期
dayOfWeek<=position<daysOfMonth + dayOfWeek 表示当前要显示月日期
position>=daysOfMonth + dayOfWeek 表示显示下一个月日期
<span style="font-family:SimSun;font-size:18px;">public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(context).inflate(
R.layout.calen_calendar_item, null);
}
TextView textView = (TextView) convertView.findViewById(R.id.tvtext);
String d = dayNumber[position].split("\\.")[0];
String dv = dayNumber[position].split("\\.")[1];
SpannableString sp = new SpannableString(d + "\n" + dv);
sp.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), 0,
d.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
sp.setSpan(new RelativeSizeSpan(1.2f), 0, d.length(),
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
if (dv != null || dv != "") {
sp.setSpan(new RelativeSizeSpan(0.75f), d.length() + 1,
dayNumber[position].length(),
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
textView.setText(sp);
textView.setTextColor(Color.GRAY);
if (position < daysOfMonth + dayOfWeek && position >= dayOfWeek) {
// 当前月信息显示
textView.setTextColor(Color.BLACK);// 当月字体设黑
// drawable = new ColorDrawable(Color.rgb(23, 126, 214));
if (position % 7 == 0 || position % 7 == 6) {
// 当前月信息显示
textView.setTextColor(Color.rgb(23, 126, 214));// 当月字体设黑
}
}
if (colorDataPosition == position) {
// 设置当天的背景
textView.setTextColor(Color.WHITE);
textView.setBackgroundResource(R.drawable.bg_circle);
} else {
textView.setBackgroundColor(res
.getColor(android.R.color.transparent));
}
return convertView;
}</span>有一个点击日期的标记，改变点击日期的背景颜色，但是有一个条件，只可以点击当月的日期，默认是系统的日期。
<span style="font-family:SimSun;font-size:18px;">public void setColorDataPosition(int position) {
if (position >= dayOfWeek && position < daysOfMonth + dayOfWeek) {
colorDataPosition = position;
notifyDataSetChanged();
}
}</span>使用步骤:
activity_main.xml
<span style="font-family:SimSun;font-size:18px;"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.example.clander.view.CalendarView
android:id="@+id/calendarview"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</com.example.clander.view.CalendarView>
</LinearLayout></span>
<span style="font-family:SimSun;font-size:18px;">public class CalendarActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CalendarView calendarview = (CalendarView) findViewById(R.id.calendarview);
//设置点击日期的事件监听
calendarview.setClickDataListener(new ClickDataListener() {
@Override
public void clickData(String year, String month, String day) {
Toast.makeText(getApplicationContext(),
year + "-" + month + "-" + day, 0).show();
}
});
}
}</span>
