Android: Setting time in time picker with the time shown in text view

You should use a SimpleDateFormat to get a Date object from your String. Then just call

picker.setCurrentHour(date.getHours())

and

picker.setCurrentMinute(date.getMinutes())

Since the Date object is deprecated, you should use a Calendar instead of it. You can instantiate a Calendar this way:

Calendar c = Calendar.getInstance();
c.setTime(date);
picker.setCurrentHour(c.get(Calendar.HOUR_OF_DAY));
picker.setCurrentMinute(c.get(Calendat.MINUTE));

Edit: the complete code:

import java.util.Date;
import java.text.SimpleDateFormat; //Don't use "android.icu.text.SimpleDateFormat"
import java.text.ParseException; //Don't use "android.net.ParseException"

SimpleDateFormat sdf = new SimpleDateFormat("hh:mm");
Date date = null;
try {
    date = sdf.parse("07:00");
} catch (ParseException e) {
}
Calendar c = Calendar.getInstance();
c.setTime(date);

TimePicker picker = new TimePicker(getApplicationContext());
picker.setCurrentHour(c.get(Calendar.HOUR_OF_DAY));
picker.setCurrentMinute(c.get(Calendar.MINUTE));

If anybody using the following format that is without using timepicker widget use this one..

mStartTime.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            new TimePickerDialog(AddAppointmentActivity.this, onStartTimeListener, calendar
                    .get(Calendar.HOUR), calendar.get(Calendar.MINUTE), false).show();

        }
    });

TimePickerDialog.OnTimeSetListener onStartTimeListener = new OnTimeSetListener() {

    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        String AM_PM;
        int am_pm;

        mStartTime.setText(hourOfDay + " : " + minute + "  " + AM_PM);
        calendar.set(Calendar.HOUR, hourOfDay);
        calendar.set(Calendar.MINUTE, minute);

    }
};
