time picker showing time like 4:7 instead of 04:07

Question

I have a time picker function which sets time in an EditText . But the format it shows is not suitable. for example for 04:07pm is shown as 4:7. whenever the digit in time is less than 10 it removes the 0 automatically. please help me out. My code is

        if (v == btnTimePicker1)                {                  // Process to get Current Time                 final Calendar c = Calendar.getInstance();                 mHour = c.get(Calendar.HOUR_OF_DAY);                 mMinute = c.get(Calendar.MINUTE);                  // Launch Time Picker Dialog                 TimePickerDialog tpd = new TimePickerDialog(this,                         new TimePickerDialog.OnTimeSetListener() {                              @Override                             public void onTimeSet(TimePicker view, int hourOfDay,                                     int minute) {                                 // Display Selected time in textbox                                 txtTime1.setText(hourOfDay + ":" + minute);                             }                         }, mHour, mMinute, false);                 tpd.show();                 } 

Answer 1

Just change the line:

txtTime1.setText(hourOfDay + ":" + minute); 

to:

txtTime1.setText(String.format("%02d:%02d", hourOfDay, minute)); 

and all will be well.

If you want a 12-hour clock instead of a 24-hour one, then replace that line with these instead:

int hour = hourOfDay % 12; if (hour == 0)     hour = 12; txtTime1.setText(String.format("%02d:%02d %s", hour, minute,                                 hourOfDay < 12 ? "am" : "pm")); 

or you could do it in just 2 lines with:

int hour = hourOfDay % 12;     txtTime1.setText(String.format("%02d:%02d %s", hour == 0 ? 12 : hour,                                minute, hourOfDay < 12 ? "am" : "pm")); 

Answer 2

The logic is simple, i have just trimmed the answers above

just replace the line where we set time in editText with

txtTime.setText(pad(hourOfDay) + ":" + pad(minute)); 

then add a function for it i.e

       public String pad(int input)           {              String str = "";              if (input > 10) {                  str = Integer.toString(input);             } else {                 str = "0" + Integer.toString(input);              }             return str;         }
