Android随时显示当前时间

//直接在方法中打
Calendar c = Calendar.getInstance();
// 获取当前年份
String mYear = String.valueOf(c.get(Calendar.YEAR));
// 获取当前月份
String mMonth = String.valueOf(c.get(Calendar.MONTH) + 1);
// 获取当前月份的日期号码
String mDay = String.valueOf(c.get(Calendar.DAY_OF_MONTH));
// 获取当前星期 他获得的是数字1 2 3 4 5 6所以根据数字换一下
String mWay = String.valueOf(c.get(Calendar.DAY_OF_WEEK));
if ("1".equals(mWay)) {
mWay = "天";
} else if ("2".equals(mWay)) {
mWay = "一";
} else if ("3".equals(mWay)) {
mWay = "二";
} else if ("4".equals(mWay)) {
mWay = "三";
} else if ("5".equals(mWay)) {
mWay = "四";
} else if ("6".equals(mWay)) {
mWay = "五";
} else if ("7".equals(mWay)) {
mWay = "六";
}
//textview赋值
date.setText(mYear + "." + mMonth + "." + mDay + " 星期"
+ mWay+" "+"今天");
