android 日历动态图标 android 日历图标显示星期

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;

}

}
