Format strings in xml data in android

Question

I'm reading data from a xml file. It works well. This is the date value. I want to cut(Delete) the time value inside date. 2014-07-03 10:05:12 It should look like this. 2014-07-03

This is my code. Could you please help me with this. Thanks in advance.

        tvResponse = (TextView) findViewById(R.id.tvResponse); 
        new PostAsync().execute(); 
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

METHOD 1: If it's simply a string, you could get away with parsing a substring. There are many methods you can use to do this, such as:

String datetime = "2014-07-03 10:05:12";
String[] date = datetime.split(" ");

Then date[0] will be equal to "2014-07-03".

METHOD 2: Since your date will always be the same length, you can use substring.

String date = datetime.substring(0,10);

METHOD 3: You can also parse dates using SimpleDateFormat.

SimpleDateFormat fromDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
SimpleDateFormat toDateFormat = new SimpleDateFormat("yyyy-MM-dd");
try { 
    String date = toDateFormat.format(fromDateFormat.parse(datetime));
} catch (ParseException e1) {
    e1.printStackTrace();
}

You have to create SimpleDateFormat to parse date in required format.

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
        formatter.format(formatter.parse(post.getDate()));

This will parse Date- 2014-07-03 10:05:12 to 2014-07-03.

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); 
String dateString = formatter.format(new Date(post.getDate()));
