如何让在日历本周天周天、日历
2023-09-13 23:59:42
作者：/
我用这个例子code HTTP： //www.androidhub4you.com/2012/10/custom-calendar-in-android.html 的我要显示在GridView中只有currrent每月的天数。我describle我下面的问题。请帮帮我。我只是瓦纳显示当前工作日。
假设今天的日期是7月21日和周三网格显示单行这个值
周日周一周二周三周四周五周六
18 19 20（21）22 23 24
但我的code将只显示该值
周日周一周二周三周四周五周六
1 2 3 4 5 6 7
我改变这个code形式例如code
//当月天
的for（int i = 1; I＆LT; = daysInMonth;我++）{
Log.d（currentMonthName，将String.valueOf（ⅰ）+
+ getMonthAsString（currentMonth）++ YY）;
如果（ⅰ== getCurrentDayOfMonth（））{
list.add（将String.valueOf（ⅰ）+蓝+ -
+ getMonthAsString（currentMonth）+ - + YY）;
} 其他 {
list.add（将String.valueOf（ⅰ）+-WHITE+ -
+ getMonthAsString（currentMonth）+ - + YY）;
}
本code
//当月天
的for（int i = 1; I＆LT; = currentWeekDay;我++）{
Log.d（currentMonthName，将String.valueOf（ⅰ）+
+ getMonthAsString（currentMonth）++
YY）;
如果（ⅰ== getCurrentDayOfMonth（））{
list.add（将String.valueOf（ⅰ）+蓝+ -
+ getMonthAsString（currentMonth）+
- + YY）;
} 其他 {
list.add（将String.valueOf（ⅰ）+-WHITE+ -
+ getMonthAsString（currentMonth）+
- + YY）;
}

解决方案
我希望这是你想要的。
重命名你的printMonth（）来printMonth_old（） 复制和粘贴如下的printMonth code 在一个行修改getView（）方法。 创建活动中的3个变量和修改的onCreate初始化它们 尝试它有你需要做的，对于eaxmple一些变化时，单击下一步按钮提前一个星期，在当点击preV。按钮回去一个星期。
1）复制并粘贴此code，重命名后您的实际printMonth
私人无效printMonth（INT毫米，INT日）
{
Log.d（标签，==＆GT; printMonth：MM：+毫米++YY：+ YY）;
INT trailingSpaces = 0;
INT daysIn prevMonth = 0;
INT currentMonth =毫米 - 1;
字符串currentMonthName = getMonthAsString（currentMonth）;
daysInMonth = getNumberOfDaysOfMonth（currentMonth）;
Log.d（标签，当前月份：++ currentMonthName +具有+ daysInMonth +天）;
GregorianCalendar的CAL =新的GregorianCalendar（YY，currentMonth，getCurrentDayOfMonth（））;
Log.d（标签，公历：=+ cal.getTime（）的toString（））;
INT currentWeekDay = cal.get（Calendar.DAY_OF_WEEK） - 1;
trailingSpaces = currentWeekDay;
Log.d（标签，周日：+ currentWeekDay +就是+ getWeekDayAsString（currentWeekDay））;
Log.d（标签，号尾部的空格添加+ trailingSpaces）;
Log.d（标签，天在previous月号：+ daysIn prevMonth）;
如果（cal.isLeapYear（cal.get（Calendar.YEAR）））
如果（毫米== 2）++ daysInMonth;
否则，如果（毫米== 3）
++ daysIn prevMonth;
//将在本周末的乞讨
INT I = getCurrentDayOfMonth（）;
INT J = currentWeekDay;
而（ⅰ→1＆安培;＆安培; J＆0）
{
一世 - ;
j--;
}
//打印一周，开始在星期日
为（J = 0; I＆LT; = daysInMonth和放大器;＆放大器; J＆LT; 7，我++，J ++）
{
Log.d（currentMonthName，将String.valueOf（我）++ getMonthAsString（currentMonth）++ YY）;
//如果是当前日期，印刷BLUE（橙色）
如果（我== actualDay＆功放;＆安培;毫米== actualMonth和放大器;＆安培; YY == actualYear）
{
list.add（将String.valueOf（ⅰ）+蓝+ - + getMonthAsString（currentMonth）+ - +日）;
}
其他
{
list.add（将String.valueOf（ⅰ）+-WHITE+ - + getMonthAsString（currentMonth）+ - +日）;
}
}
}
2）更改getView方法，只添加一行：
如果（day_color [1] .equals（蓝色））
{
//只添加以下行
gridcell.setText（（+ theday +））;
gridcell.setTextColor（getResources（）的getColor（R.color.orrange））;
}
3）在活动中加入这一行：
公共类MyCalendarActivity扩展活动实现OnClickListener
{
....
私人诠释月，年;
//添加此线下方
私人诠释actualYear，actualMonth，actualDay;
和上的onCreate（）中加入这一行，以及：
公共无效的onCreate（包savedInstanceState）
{
....
一个月= _calendar.get（Calendar.MONTH）+ 1;
年= _calendar.get（Calendar.YEAR）;
//添加这3行
actualYear =年;
actualMonth =月;
actualDay = _calendar.get（Calendar.DAY_OF_MONTH）;
I'm using this examplecode http://www.androidhub4you.com/2012/10/custom-calendar-in-android.html I want to show only currrent month days in gridview. I describle my problem below. Help me please. I just wana show current week days.
Suppose today date is 21 july and Wednesday grid show single row with this values
Sun Mon tues Wed Thurs Fri Sat
18 19 20 (21) 22 23 24
but my code will only display this value
Sun Mon tues Wed Thurs Fri Sat
1 2 3 4 5 6 7
I change this code form example code
// Current Month Days
for (int i = 1; i <= daysInMonth; i++) {
Log.d(currentMonthName, String.valueOf(i) + " "
+ getMonthAsString(currentMonth) + " " + yy);
if (i == getCurrentDayOfMonth()) {
list.add(String.valueOf(i) + "-BLUE" + "-"
+ getMonthAsString(currentMonth) + "-" + yy);
} else {
list.add(String.valueOf(i) + "-WHITE" + "-"
+ getMonthAsString(currentMonth) + "-" + yy);
}
with this code
// Current Month Days
for (int i = 1; i <= currentWeekDay; i++) {
Log.d(currentMonthName, String.valueOf(i) + " "
+ getMonthAsString(currentMonth) + " " +
yy);
if (i == getCurrentDayOfMonth()) {
list.add(String.valueOf(i) + "-BLUE" + "-"
+ getMonthAsString(currentMonth) +
"-" + yy);
} else {
list.add(String.valueOf(i) + "-WHITE" + "-"
+ getMonthAsString(currentMonth) +
"-" + yy);
}

解决方案
I hope this is what you want.
Rename your printMonth() to printMonth_old () Copy and paste the printMonth code below Modify the getView() method with one line. Create the 3 variables in the Activity and modify the onCreate to initialize them Try itThere are some changes you need to do, for eaxmple when click the Next Button advance one week and the when click Prev. Button go back one week.
1) Copy and paste this code, after renaming your actual printMonth
private void printMonth(int mm, int yy)
{
Log.d(tag, "==> printMonth: mm: " + mm + " " + "yy: " + yy);
int trailingSpaces = 0;
int daysInPrevMonth = 0;
int currentMonth = mm - 1;
String currentMonthName = getMonthAsString(currentMonth);
daysInMonth = getNumberOfDaysOfMonth(currentMonth);
Log.d(tag, "Current Month: " + " " + currentMonthName + " having " + daysInMonth + " days.");
GregorianCalendar cal = new GregorianCalendar(yy, currentMonth, getCurrentDayOfMonth());
Log.d(tag, "Gregorian Calendar:= " + cal.getTime().toString());
int currentWeekDay = cal.get(Calendar.DAY_OF_WEEK) - 1;
trailingSpaces = currentWeekDay;
Log.d(tag, "Week Day:" + currentWeekDay + " is " + getWeekDayAsString(currentWeekDay));
Log.d(tag, "No. Trailing space to Add: " + trailingSpaces);
Log.d(tag, "No. of Days in Previous Month: " + daysInPrevMonth);
if (cal.isLeapYear(cal.get(Calendar.YEAR)))
if (mm == 2) ++daysInMonth;
else if (mm == 3)
++daysInPrevMonth;
// move at the begging of the week
int i = getCurrentDayOfMonth();
int j = currentWeekDay;
while (i > 1 && j > 0)
{
i--;
j--;
}
// print the week, starting at Sunday
for (j = 0; i <= daysInMonth && j < 7; i++, j++)
{
Log.d(currentMonthName, String.valueOf(i) + " " + getMonthAsString(currentMonth) + " " + yy);
// If it is the current date, printing in BLUE (Orange)
if (i == actualDay && mm == actualMonth && yy == actualYear)
{
list.add(String.valueOf(i) + "-BLUE" + "-" + getMonthAsString(currentMonth) + "-" + yy);
}
else
{
list.add(String.valueOf(i) + "-WHITE" + "-" + getMonthAsString(currentMonth) + "-" + yy);
}
}
}
2) Change the getView method, only add one line:
if (day_color[1].equals("BLUE"))
{
// Add only the following line
gridcell.setText("(" + theday + ")");
gridcell.setTextColor(getResources().getColor(R.color.orrange));
}
3) On the Activity add this line:
public class MyCalendarActivity extends Activity implements OnClickListener
{
....
private int month, year;
// add this line below
private int actualYear, actualMonth, actualDay;
And on the onCreate() add these lines as well:
public void onCreate(Bundle savedInstanceState)
{
....
month = _calendar.get(Calendar.MONTH) + 1;
year = _calendar.get(Calendar.YEAR);
// Add these 3 lines
actualYear = year;
actualMonth = month;
actualDay = _calendar.get(Calendar.DAY_OF_MONTH);
