Many of the tools are missing

Question

When I'm designing Android app using Android studio I can not see most of the tools in palette like analog,digital clocks,date picker and time picker. Etc.. how do I get them.

Answer 1

these are the codes for date and time picker dialogs DatePickerDialog StartTime = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() { public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { Calendar newDate = Calendar.getInstance(); newDate.set(year, monthOfYear, dayOfMonth); activitydate.setText(dateFormatter.format(newDate.getTime())); }

      }, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH),    newCalendar.get(Calendar.DAY_OF_MONTH));

 btn_checkin.setOnClickListener(new View.OnClickListener() {
                                       @Override
                                       public void onClick(View v) {
 StartTime .show():

 });
