blocks|key|238236|text|首先，使用SimpleDateFormat将日期字符串转换为日期。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|238237|然后从该日期创建一个Calendar实例。|238238|最后，使用get(Calendar.DAY_OF_WEEK)从Calendar中检索星期几。这将给出一个介于1到7之间的整数，表示一周中的第几天。您可以简单地将其映射到一个字符串数组来获取日期。|238239|entityMap^0|5|G|0|A|8|0|5|P|V|8|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|R|8|@$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|K|$]]

First convert the date string to a Date using <code>SimpleDateFormat</code>.

Then make a <code>Calendar</code> instance from that date. 

Finally, retrieve the day of week from the <code>Calendar</code> using the <code>get(Calendar.DAY_OF_WEEK)</code>. This will give you an integer between 1 to 7 representing the day of the week. You can simple map this to an array of Strings to get the days.

blocks|key|2905380|text|在@vivek的回答中，在calendar.get(Calendar.DAY_OF_WEEK)添加"-1"，因为它返回从1到7的数字，但字符串数组的索引是从0到6。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|BOLD|entityRanges|data|2905381|calendar.setTime(date_your_want_to_know);

On @vivek's answer add "-1" at <code>calendar.get(Calendar.DAY_OF_WEEK)</code>, since it returns numbers from 1 to 7 but the String array is indexed from 0 to 6.

<pre><code>calendar.setTime(date_your_want_to_know);

String[] days = new String[] { "SUNDAY", "MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY" }

String day = days[calendar.get(Calendar.DAY_OF_WEEK)-1];

Try this code. Hope it will work.
This is worked for me.

<pre><code>public String daysNameOfWeek(String inputDate){

 DateFormat df = DateFormat.getDateInstance(DateFormat.MEDIUM, Locale.UK);
 try {

 Date date = df.parse(inputDate.trim());
 SimpleDateFormat outFormat = new SimpleDateFormat("EEEE");

 } catch (ParseException e) {
 e.printStackTrace();

 return daysName;

Below method will return the day by passing the date in String format.
null is returned if exception occurs.

<pre><code>private String getDay(String date_in_string_format){ 
 DateFormat df = DateFormat.getDateInstance();
 Date date;
 try {
 date = df.parse(date_in_string_format);
 } catch (Exception e) {
 Log.e("Error:","Exception " + e);
 return null;
 }
 return new SimpleDateFormat("EEEE").format(date);
 }
</code></pre>

Hope it helps.
