我必须从警报对话框设置日期和日期。我创建了一个新的XML布局来获取Date Time Picker的值。但是我不知道如何在每个Textview上获得不同的价值。
MainFragment extends Fragment implements
DatePickerDialog.OnDateSetListener, TimePickerDialog.OnTimeSetListener {
int day, month, year, hour, minute;
int dayFinal, monthFinal, yearFinal, hourFinal, minuteFinal;
String dayFinalString, monthFinalString, yearFinalString, hourFinalString, minuteFinalString;
TextView et2;
String dateFrom;
String Dates, time;
@Override
public void onDateSet(DatePicker datePicker, int i, int i1, int i2) {
yearFinal = i;
monthFinal = i1 + 1;
dayFinal = i2;
Calendar c = Calendar.getInstance();
hour = c.get(Calendar.HOUR_OF_DAY);
minute = c.get(Calendar.MINUTE);
Dates = (monthFinal < 10 ? ("0" + monthFinal) : (monthFinal)) + "-" + (dayFinal < 10 ? ("0" + dayFinal) : (dayFinal)) + "-" + yearFinal ;
TimePickerDialog timePickerDialog = new TimePickerDialog(_context, this, hour, minute, DateFormat.is24HourFormat(_context));
timePickerDialog.show();
}
@Override
public void onTimeSet(TimePicker timePicker, int i, int i1) {
hourFinal = i;
minuteFinal = i1;
time = (hourFinal < 10 ? ("0" + hourFinal) : (hourFinal)) + ":" + (minuteFinal < 10 ? ("0" + minuteFinal) : (minuteFinal));
//Here I want to set for example
et2.setText(Dates + " " + time + ":00");
dateFromListFragment = et2.getText().toString();
et3.setText(Dates + " " + time + ":00");
dateFromListFragment = et3.getText().toString();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
....
@Override
public void onClick(View view) {
final Dialog dialog = new Dialog(getContext());
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.date_time);
dialog.setCancelable(false);
ImageView close = (ImageView) dialog.findViewById(R.id.close);
close.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
dialog.dismiss();
}
});
et2 = (TextView) dialog.findViewById(R.id.editText2);
et2.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(_context, SnailTrailTwoHrsFragment.this, year, month, day);
datePickerDialog.show();
}
});
final TextView et3 = (TextView) dialog.findViewById(R.id.editText3);
et3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(_context, SnailTrailTwoHrsFragment.this, year, month, day);
datePickerDialog.show();
}
});
}
这是我的XML

当我按DateTimePicker与Date From TextView相同时，我希望在对话框中设置Date To TextView。
问题：当我按下Date From TextView时，我无法获得Date Time Picker的值，并设置为Date From与Date To相同。
