我想问一下如何更改分钟间隔。我要在 15 分钟内完成。现在我使用日期和时间选择器，但我不想选择所有的分钟，而只能选择 0、15、30、45 单击editText ed_hours 时，日期和时间选择器开始。
int day,month,year,hour,minute;
int dayfinal,monthfinal,yearfinal,hourfinal,minutefinal;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_search);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
back = findViewById(R.id.btn_saveHours);

// ed2 =(EditText) findViewById(R.id.textthemess);

ed4 = (EditText) findViewById(R.id.txt_numbre);
// String name = ed_hours.getText().toString();
ed_hours.setInputType(InputType.TYPE_NULL);
ed_hours.setOnClickListener(new View.OnClickListener() {

switch (item.getItemId()) {

}
private void showDateTimeDialog(final EditText date_time_in) {
final Calendar calendar=Calendar.getInstance();
DatePickerDialog.OnDateSetListener dateSetListener=new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
calendar.set(Calendar.YEAR,year);
calendar.set(Calendar.MONTH,month);

date_time_in.setText(simpleDateFormat.format(calendar.getTime()));
}
};
new TimePickerDialog(UserActivitySearch.this,timeSetListener,calendar.get(Calendar.HOUR_OF_DAY),calendar.get(Calendar.MINUTE),true).show();
}
};
new DatePickerDialog(UserActivitySearch.this,dateSetListener,calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_MONTH)).show();

我希望同时选择日期和时间选择器
