上一篇文档中谈到了在日历图标上显示当前日期，
现在我添加了几行代码，可以在日历图标上显示对应的星期；
修改源码是在Utilities.java中
函数createCalendarIconBitmap
添加几行代码：
int dayOfWeek = Calendar.getInstance().get(Calendar.DAY_OF_WEEK);
String weekStrings[] = {"周日","周一","周二","周三","周四","周五","周六"};
String weekString = weekStrings[dayOfWeek];
Paint mWeekPaint = new Paint();
mWeekPaint.setTypeface(Typeface.DEFAULT_BOLD);
mWeekPaint.setTextSize((int)10F * mDensity);
mWeekPaint.setColor(0xff000000);
mWeekPaint.setAntiAlias(true);
Rect rect1 = new Rect();
mWeekPaint.getTextBounds(weekString,0,weekString.length(),rect1);
int hoffset0 = 2;
int width10 = rect1.right - rect1.left;
int height10 = rect1.bottom - rect1.top + hoffset0;
int width20 = calendarIcon.getWidth();
int height20 = calendarIcon.getHeight() ;//+ hoffset0;
canvas.drawText(weekString,(width20 - width10)/2 - rect1.left,height10,mWeekPaint);
修改后的函数为：
static Bitmap createCalendarIconBitmap(Drawable icon, Context context){
Bitmap calendarIcon = createIconBitmap(icon,context);
String dayString = String.valueOf(Calendar.getInstance().get(Calendar.DAY_OF_MONTH));
int dayOfWeek = Calendar.getInstance().get(Calendar.DAY_OF_WEEK);
String weekStrings[] = {"周日","周一","周二","周三","周四","周五","周六"};
String weekString = weekStrings[dayOfWeek];
Log.d("tanfusheng","weekString"+weekString);
synchronized (sCanvas) {
final Canvas canvas = sCanvas;
canvas.setBitmap(calendarIcon);
final float mDensity = context.getResources().getDisplayMetrics().density;
Paint mWeekPaint = new Paint();
mWeekPaint.setTypeface(Typeface.DEFAULT_BOLD);
mWeekPaint.setTextSize((int)10F * mDensity);
mWeekPaint.setColor(0xff000000);
mWeekPaint.setAntiAlias(true);
Rect rect1 = new Rect();
mWeekPaint.getTextBounds(weekString,0,weekString.length(),rect1);
int hoffset0 = 2;
int width10 = rect1.right - rect1.left;
int height10 = rect1.bottom - rect1.top + hoffset0;
int width20 = calendarIcon.getWidth();
int height20 = calendarIcon.getHeight() ;//+ hoffset0;
canvas.drawText(weekString,(width20 - width10)/2 - rect1.left,height10,mWeekPaint);
Paint mDatePaint = new Paint();
mDatePaint.setTypeface(Typeface.DEFAULT_BOLD);
mDatePaint.setTextSize((int)30F * mDensity);
mDatePaint.setColor(0xff000000);
mDatePaint.setAntiAlias(true);
Rect rect = new Rect();
mDatePaint.getTextBounds(dayString,0,dayString.length(),rect);
int hoffset = 20;
int width1 = rect.right - rect.left;
int height1 = rect.bottom - rect.top;
int width2 = calendarIcon.getWidth();
int height2 = calendarIcon.getHeight() + hoffset;
canvas.drawText(dayString,(width2 - width1)/2 - rect.left,(height2 - height1)/2 - rect.top,mDatePaint);
canvas.setBitmap(null);
return calendarIcon;
}
}
