java - 从 String 在 DatePickerDialog 中设置日期

Question

如何通过字符串在 DatePicker 中设置日期(例如:02/10/19):

代码如下:

  iqp_editDate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new DatePickerDialog(ActivityClass.this, (DatePickerDialog.OnDateSetListener) date1, y, m, d).show();
        }
    });

 DatePickerDialog.OnDateSetListener date1 = new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {      
        y = year;
        m = month;
        d = dayOfMonth;
        dateMonth = month + 1;
        dateYear = year;
    }
};

更新:误解了问题:

Calendar cal = Calendar.getInstance()
cal.set(Calendar.HOUR_OF_DAY,18);
cal.set(Calendar.MINUTE,0);
cal.set(Calendar.DATE,2);
cal.set(Calendar.MONTH,9); //Month -1

//Or to set it from a String:
String string = "02/10/19";
DateFormat format = new SimpleDateFormat("dd/MM/yy", Locale.getDefault());
Date date = format.parse(string);
cal.setTimeInMillis(date.getTime());

new DatePickerDialog(getContext(),date1, cal 
                                    .get(Calendar.YEAR), cal .get(Calendar.MONTH),
                                    cal .get(Calendar.DAY_OF_MONTH)).show();
