你可以使用 SimpleDateFormat

只需查看此链接，您就可以获得想法的样例。

例如：

  String dateStr =04/05/2010; 

 SimpleDateFormat curFormater = new SimpleDateFormat（dd / MM / yyyy）; 
日期dateObj = curFormater.parse（dateStr）; 
 SimpleDateFormat postFormater = new SimpleDateFormat（MMMM dd，yyyy）; 

 String newDateStr = postFormater.format（dateObj）; 
 

更新：

详细示例是 here 和这里，我建议您通过这个例子，了解SimpleDateFormat类的概念。

最终解决方案：

 日历c = Calendar.getInstance（） ; 
 System.out.println（当前时间=>+ c.getTime（））; 

 SimpleDateFormat df = new SimpleDateFormat（dd-MMM-yyyy）; 
 String formattedDate = df.format（c.getTime（））; 
 

I wrote the following code

Date d = new Date();
CharSequence s  = DateFormat.format("MMMM d, yyyy ", d.getTime());

But is asking me parameter, I want current date in string format,

like

28-Dec-2011

so that I can set over TextView,

explain a bit, if you think something is necessary, I am new to Android Development.

You can use the SimpleDateFormat class for formatting date in your desired format.

Just check this link where you get idea for your example.

For example:

String dateStr = "04/05/2010"; 

SimpleDateFormat curFormater = new SimpleDateFormat("dd/MM/yyyy"); 
Date dateObj = curFormater.parse(dateStr); 
SimpleDateFormat postFormater = new SimpleDateFormat("MMMM dd, yyyy"); 

String newDateStr = postFormater.format(dateObj); 

Update:

Detailed example is here and here, I would suggest you to go through this example and understand the concept of SimpleDateFormat class.

Final Solution:

Calendar c = Calendar.getInstance();
System.out.println("Current time => " + c.getTime());

SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
String formattedDate = df.format(c.getTime());
