Simpledateformat is not giving proper date

I want today's date in my application to store it in a database as a string but when i used simpledatefromat and calender.getInstance(), it's not giving me proper date. The code is as below.
I tried simpledateformat's another constructor which takes locale as parameter but still not showing proper date
Date date = Calendar.getInstance().getTime();
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-mm-yyyy");
String dateF = dateFormat.format(date);
expected date should be 21-04-2019
actual result 21-26-2019

To get the month like the way that you want, you need to change "dd-mm-yyyy" to "dd-MM-yyyy"
Date date = Calendar.getInstance().getTime();
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy", Locale.US);
String dateF = dateFormat.format(date);

Android - How to add days to date

I have retrieved a Date from a SQLiteDatabase and have formatted it to how I want via the following;
String steepingDate = (c.getString(3));
SimpleDateFormat formatter = new SimpleDateFormat("dd/MMM/yyyy");
Date steepingdate = formatter.parse(steepingDate);
I now want to give the user the option to increase whatever date is in steepingdate by a certain amount of days that the user can input
I know you can use;
Date today = calendar.getTime();
calendar.add(Calendar.DAY_OF_YEAR, 10);
For example to add 10 days onto todays date
But how do you do it so that it uses steepingdate instead of todays date
Thanks
UPDATE;
The calendar is working as I want, but I now want to save the new data to the database, the full code is as following;
String steepingDate = (c.getString(3));
SimpleDateFormat formatter = new SimpleDateFormat("dd/MMM/yyyy");
Date steepingdate = formatter.parse(steepingDate);
Integer amountDays = Integer.parseInt(TSExtend.getText().toString());
Calendar ca = Calendar.getInstance();
ca.setTime(steepingdate);
ca.add(Calendar.DAY_OF_YEAR, amountDays);
DateFormat dateFormat = new SimpleDateFormat("dd/MMM/yyyy");
String newDate = dateFormat.format(ca);
I'm getting the error;
Bad class: class
java.util.GregorianCalendar
Any ideas?

To add 10 days to steepingdate, you can use:
Calendar calendar = Calendar.getInstance();
calendar.setTime(steepingdate);
calendar.add(Calendar.DAY_OF_YEAR, 10);
it the number is provided, through the user interface, you can use the View.OnClickListener and when onClick is fired, read the value from an EditText, and use this value instead of 10

Set the time of the calendar to your date, then add the days
Calendar cal = Calendar.getInstance();
cal.setTime(steepingdate);
cal.add(Calendar.DATE, 10);
UPDATE:
You can't directly format a Calendar, first get the Date from the Calendar, then format it.
String newDate = dateFormat.format(ca.getTime());

Getting the current time and date in the device's defined format

How can I get the current time and date according to phone device format?
my code is
Date date = new Date(System.currentTimeMillis());
SimpleDateFormat dateFormat = new SimpleDateFormat("hh:mm aa",
Locale.ENGLISH);
String var = dateFormat.format(date));
It displays like 2PM instead of 14PM.

You can the device format data and time using
Date date = new Date();
DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());
Log.d(TAG,dateFormat.format(date)+");

Use calendar object instead of Date because it is deprecated now and by using caledar object you can get hour in 12 hours formate as
int hour = calendarObject.get(Calendar.HOUR);
for 24 formate as:
int hour = calendarObject.get(Calendar.HOUR_OF_DAY);
for further detail you can visit this

Just change "hh:mm aa" to "HH:mm aa"

Android Today's date

Hello I want to display current date. I trying do it like this:
calendar c = Calendar.getInstance();
System.out.println("Current time => "+c.getTime());
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String formattedDate = df.format(c.getTime());
TextView txtView = (TextView)findViewById(R.id.tvDate);
txtView.setText("Current Date and Time : "+formattedDate);
But it don't display the date in my textView.
Is there a better way to display the same date? I want like this: Monday, April 22

You should look at the documentation for SimpleDateFormat.
SimpleDateFormat
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
should be
SimpleDateFormat df = new SimpleDateFormat("EEEE, MMMMM dddd");

Date now = new Date();
String str = DateUtils.getRelativeDateTimeString(
this, // Suppose you are in an activity or other Context subclass
now.getTime(), // The time to display
MINUTE_IN_MILLIS, // The resolution. This will display only minutes
// (no "3 seconds ago"
WEEK_IN_MILLIS, // The maximum resolution at which the time will switch
// to default date instead of spans. This will not
// display "3 weeks ago" but a full date instead
0); // Eventual flags
Other values for MINUTE_IN_MILLIS and YEAR_IN_MILLIS include:
SECOND_IN_MILLIS
MINUTE_IN_MILLIS
HOUR_IN_MILLIS
DAY_IN_MILLIS
WEEK_IN_MILLIS
YEAR_IN_MILLIS
Any custom value in milliseconds
Then set text as
txtView.setText("Current Date and Time : "+now);

displaying date in edit text android

In my application i have edit text that will show the current date and time initially . If i change the date to some other date and when i tried to use gettext() i am still getting the current date. can anyone help. This is my code to set initial value in edit text
TaskTime = (EditText) findViewById(R.id.txtTaskTime);
Date date = new Date();
java.text.DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());
TaskDate.setText(dateFormat.format(date));

Most of the use of date object is obsolete in Android, you should use Calendar : http://developer.android.com/reference/java/util/Calendar.html

Yes, you can get the current date because , Date date = new Date(); this function always returns the current date .
So you need to use the Calendar object to get the current date and time .
Example
Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);
String strDate = sdf.format(cal.getTime());
Here in dateFormat you have to declare your date format . dateFormat = "dd/MM/yyyy" like .
