TimePicker Dialog from clicking EditText

Question

eReminderTime.setText( "" + selectedHour + ":" + selectedMinute);

Your missing a + between "" and selected hour, setText methods only take a single string, so you need to concatenate all the parts (the first quotes are likely unnecessary).

eReminderTime.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Calendar mcurrentTime = Calendar.getInstance();
            int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
            int minute = mcurrentTime.get(Calendar.MINUTE);
            TimePickerDialog mTimePicker;
            mTimePicker = new TimePickerDialog(AddReminder.this, new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                    eReminderTime.setText( selectedHour + ":" + selectedMinute);
                }
            }, hour, minute, true);//Yes 24 hour time
            mTimePicker.setTitle("Select Time");
            mTimePicker.show();

        }
    });

That should fix your second error, you weren't providing the last parameter. TimePickerDialog Constructors

Why not write in a re-usable way ?

Create SetTime class:

class SetTime implements OnFocusChangeListener, OnTimeSetListener {   

       private EditText editText;
       private Calendar myCalendar;

       public SetTime(EditText editText, Context ctx){
           this.editText = editText;
           this.editText.setOnFocusChangeListener(this);
           this.myCalendar = Calendar.getInstance();

       }

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            // TODO Auto-generated method stub
            if(hasFocus){
                int hour = myCalendar.get(Calendar.HOUR_OF_DAY);
                int minute = myCalendar.get(Calendar.MINUTE);
                new TimePickerDialog(ctx, this, hour, minute, true).show();
            }
        }

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            // TODO Auto-generated method stub
            this.editText.setText( hourOfDay + ":" + minute);
        }

    }

Then call it from onCreate function:

    EditText editTextFromTime = (EditText) findViewById(R.id.editTextFromTime);
    SetTime fromTime = new SetTime(editTextFromTime, this);

You can use the below code in the onclick listener of edittext

  TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this,
    new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay,
                              int minute) {

            tv_time.setText(hourOfDay + ":" + minute);
        }
    }, hour, minute, false);
     timePickerDialog.show();

I extended the nice reusable solution of @Sumoanand to support both focus change and click listeners when changing the time multiple times. Also updating the picker calendar to remember the last selected time + formatting HH:mm

public class TimeSetter implements View.OnFocusChangeListener, TimePickerDialog.OnTimeSetListener, View.OnClickListener {

    private EditText mEditText;
    private Calendar mCalendar;
    private SimpleDateFormat mFormat;

    public TimeSetter(EditText editText){
       this.mEditText = editText;
       mEditText.setOnFocusChangeListener(this);
       mEditText.setOnClickListener(this);
    }

    @Override
    public void onFocusChange(View view, boolean hasFocus) {
        if (hasFocus){
            showPicker(view);
        }
    }

    @Override
    public void onClick(View view) {
        showPicker(view);
    }

    private void showPicker(View view) {
        if (mCalendar == null)
            mCalendar = Calendar.getInstance();

        int hour = mCalendar.get(Calendar.HOUR_OF_DAY);
        int minute = mCalendar.get(Calendar.MINUTE);

        new TimePickerDialog(view.getContext(), this, hour, minute, true).show();
    }

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        mCalendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
        mCalendar.set(Calendar.MINUTE, minute);

        if (mFormat == null)
            mFormat = new SimpleDateFormat("HH:mm", Locale.getDefault());

        this.mEditText.setText(mFormat.format(mCalendar.getTime()));
    }

}

Usage from onCreate:

EditText timeEditText = (EditText) rootView.findViewById(R.id.timeText);
new TimeSetter(timeEditText);

I dont know if this will work for you, it works for me just fine.

Create a method for the Date/Time picker dialog.

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {

    // when dialog box is called, below method will be called.
    // The arguments will be working to get the Day of Week to show it in a special TextView for it.

    public void onDateSet(DatePicker view, int selectedYear,
                          int selectedMonth, int selectedDay) {
        String year1 = String.valueOf(selectedYear);
        String month1 = String.valueOf(selectedMonth + 1);
        String day1 = String.valueOf(selectedDay);
        delivDate.setText(month1 + "/" + day1 + "/" + year1);
        delivDay.setText(DateFormat.format("EEEE", new Date(selectedYear, selectedMonth, selectedDay - 1)).toString());
    }
};

and then, wherever you want you can do it just like this

public void setDateOnClick (View view) {
    Calendar cal = Calendar.getInstance();

    DatePickerDialog datePicker = new DatePickerDialog(this, datePickerListener,
            cal.get(Calendar.YEAR),
            cal.get(Calendar.MONTH),
            cal.get(Calendar.DAY_OF_MONTH));
    //Create a cancel button and set the title of the dialog.
    datePicker.setCancelable(false);
    datePicker.setTitle("Select the date");
    datePicker.show();
}

hope you find this as your solution.
