TextView textView;
int interval = 2;
#Override

getDate(interval);
}
}
public void getDate(int interval) {
try {
Calendar c = GregorianCalendar.getInstance();
c.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
c.add(Calendar.DAY_OF_WEEK, interval - 2);
DateFormat df = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());
String startDate = "", endDate = "";
startDate = df.format(c.getTime());
c.add(Calendar.DATE, 6);
endDate = df.format(c.getTime());
textView.setText(startDate + " to " + endDate);
Date date = new Date();
String modifiedDate = new SimpleDateFormat("yyyy-MM-dd").format(date);
if ( endDate.compareTo(modifiedDate) > 0) {
Log.d("data", "" + "");
}
Log.d("data", "" + "");
} catch (Exception e) {

Using this code, i am displaying Monday to Sunday like
2017-7-3 to 2017-7-9 ,2017-7-10 to 2017-7-16 ,2017-7-17 to 2017-7-23
,2017-7-24 to 2017-7-30 ,2017-7-31 to 2017-8-5 ...
Receptively but what I want, if current week is
2017-7-24 to 2017-7-30
then when we click on next week it should display it should display only previous week please suggest me in this scenario I will compare date.


if (c.getTime().after(new Date())){
next.setVisibility(View.GONE);
}else {
next.setVisibility(View.VISIBLE);
}
apply this Condition and enjoy !!

Good implementation, proper updated answer:
LocalDate date1 = LocalDate.of(2021, Month.JANUARY, 1);
LocalDate date2 = date1.withYear(2010);
LocalDate date3 = date2.withMonth(Month.DECEMBER.getValue());
LocalDate date4 = date3.withDayOfMonth(15);
LocalDate date5 = date4.with(ChronoField.DAY_OF_YEAR, 100);
Stolen from https://kodejava.org/how-do-i-manipulate-the-value-of-localdate-object/
Bad outdated implementation, bad answer (just here for protocol)
Simple pure Java implementation:
Use Calendar. Create a new instance; you probably want Gregorian Calendar: Calendar.getInstance();
Set the calendar value to the date: cal.setTime(pDate);
adjust single fields: cal.add(pField, pValue); or cal.set(pField, pValue);
retrieve Date object: cal.getTime();
You could also use the new java.time package, with classes like LocalDateTime etc.
And then there's a myriad of Java Date Time libraries out there.
Choose the way that works best for you.

button that take the date of datepicker(year,month,day) in android studio

i want to take the date that looks like that ("Year-mm-DD") from date picker in android studio and compare if it with the current date when i press a button.
public class UserMenu extends ActionBarActivity {
DatePicker date;
ImageButton next;
Date currentDate;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_menu);
date = (DatePicker) findViewById(R.id.datePicker);
next = (ImageButton) findViewById(R.id.nxt);
currentDate = new Date();
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd");
String dateFormat = dateformat.format(new Date(date.getYear(), date.getMonth(), date.getDayOfMonth()));
String nowDate = new SimpleDateFormat("yyyy-MM-dd").format(currentDate);
if (dateFormat.compareTo(nowDate) < 0) {
Toast.makeText(getApplicationContext(), "The date is too old", Toast.LENGTH_LONG);
} else {
Intent i = new Intent(UserMenu.this, UserMenuTime.class);
i.putExtra("date", dateFormat);
startActivity(i);
}
}
});
}
}

Use before and after methods to compare dates:
Date pickerDate = new Date(date.getYear(), date.getMonth(), date.getDayOfMonth());
if (pickerDate.before(currentDate)) {
Toast.makeText(getApplicationContext(), "The date is too old", Toast.LENGTH_LONG);
} else {
Intent i = new Intent(UserMenu.this, UserMenuTime.class);
i.putExtra("date", dateFormat);
startActivity(i);
}

TextView timer seconds digits jumping

I have this code which simply displays a countdown clock to an event. I am having an issue with it with regards to the last seconds place jumping digits unlike a normal clock. Here is the code I am working with. Could someone please offer some guidance to where this issue may be. Kind regards.
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new Timer().schedule(new TimerTask() {
File sdcard = Environment.getExternalStorageDirectory();
File cfgFile = new File(sdcard, "TimeTillParis/config.txt");
#Override
public void run() {
runOnUiThread(new Runnable() {
public void run() {
try {
InputStream is = new FileInputStream(cfgFile);
Properties prop = new Properties();
prop.load(is);
int mmY = Integer.parseInt(prop.getProperty("YEAR"));
int mmM = Integer.parseInt(prop.getProperty("MONTH"));
int mmD = Integer.parseInt(prop.getProperty("DAY"));
int mmH = Integer.parseInt(prop.getProperty("HOUR"));
int mmC = Integer.parseInt(prop.getProperty("MINUTE"));
int mmS = Integer.parseInt(prop.getProperty("SECOND"));
Calendar cal = Calendar.getInstance();
Date today = new Date(System.currentTimeMillis());
cal.set(Calendar.YEAR, mmY);
cal.set(Calendar.MONTH, mmM);
cal.set(Calendar.DAY_OF_MONTH, mmD);
cal.set(Calendar.HOUR_OF_DAY, mmH);
cal.set(Calendar.MINUTE, mmC);
cal.set(Calendar.SECOND, mmS);
long milliseconds = (cal.getTimeInMillis() - today.getTime());
String mD="", mH="", mM="", mS="", boxText="";
mD += (milliseconds / (1000*60*60*24));
mH += (milliseconds / (1000*60*60) % 24);
mM += (milliseconds / (1000*60) % 60);
mS += (milliseconds / 1000 % 60);
boxText += "Next visit to Paris in \n\n" +
mD + "d " +
mH + "h " +
mM + "m " +
mS + "s";
TextView textView = (TextView) findViewById(R.id.textView_date_display);
textView.setText(boxText);
} catch (FileNotFoundException e) {
String cfgNotFound="";
cfgNotFound += "config.txt not found!";
TextView textView = (TextView) findViewById(R.id.textView_date_display);
textView.setText(cfgNotFound);
//e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
}, 0, 100);
}
}

I prepared complete solution, let me know if you have some questions:
public class MainActivity extends Activity {
private static final int COUNTDOWN_INTERVAL = 1000;
MyTimer timer;
Calendar eventTime;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
File sdcard = Environment.getExternalStorageDirectory();
File cfgFile = new File(sdcard, "TimeTillParis/config.txt");
try {
InputStream is = new FileInputStream(cfgFile);
Properties prop = new Properties();
prop.load(is);
int mmY = Integer.parseInt(prop.getProperty("YEAR"));
int mmM = Integer.parseInt(prop.getProperty("MONTH"));
int mmD = Integer.parseInt(prop.getProperty("DAY"));
int mmH = Integer.parseInt(prop.getProperty("HOUR"));
int mmC = Integer.parseInt(prop.getProperty("MINUTE"));
int mmS = Integer.parseInt(prop.getProperty("SECOND"));
Calendar cal = Calendar.getInstance();
cal.set(Calendar.YEAR, mmY);
cal.set(Calendar.MONTH, mmM);
cal.set(Calendar.DAY_OF_MONTH, mmD);
cal.set(Calendar.HOUR_OF_DAY, mmH);
cal.set(Calendar.MINUTE, mmC);
cal.set(Calendar.SECOND, mmS);
eventTime = cal;
} catch (FileNotFoundException e) {
String cfgNotFound="";
cfgNotFound += "config.txt not found!";
TextView textView = (TextView) findViewById(R.id.textView_date_display);
textView.setText(cfgNotFound);
//e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
protected void onResume() {
super.onResume();
if(eventTime != null) {
long millisInFuture = (eventTime.getTimeInMillis() - System.currentTimeMillis());
timer = new MyTimer(this, millisInFuture, COUNTDOWN_INTERVAL);
timer.start();
}
}
#Override
protected void onPause() {
super.onPause();
if(timer != null) {
timer.cancel();
}
}
private static class MyTimer extends CountDownTimer {
TextView textView;
public MyTimer(Activity actitivy, long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
// findViewById is very expansive, so fined it only once
textView = (TextView) actitivy.findViewById(R.id.textView_date_display);
}
#Override
public void onFinish() {
}
#Override
public void onTick(long millisUntilFinished) {
SimpleDateFormat sdf = new SimpleDateFormat("'Next visit to Paris in \n\n'd'd 'h'h 'm'm 's's'");
String boxText = sdf.format(new Date(millisUntilFinished));
textView.setText(boxText);
}
}
}
