MainActivity.java:
e6.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm");
Calendar mcurrentTime = Calendar.getInstance();
int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
int minute = mcurrentTime.get(Calendar.MINUTE);
TimePickerDialog mTimePicker;
mTimePicker = new TimePickerDialog(AddFlight.this, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
e6.setText(selectedHour + ":" + selectedMinute);
}
}, hour, minute, true);//Yes 24 hour time
mTimePicker.setTitle("Select Time");
mTimePicker.show();
}
});
它运行良好并显示时间选择器.但我的问题是,当我选择时间戳中的04:15时,它显示4:15.它之前不包括0.我需要在hh中显示时间选择器:mm格式.
任何人都可以帮助我.谢谢.
