Android - Insert Date in Editext
Question
I have a screen with calendar view, if clicked in any date will go for a new screen with edittext for date input and others data.I wanted that the date clicked will appearing in the EditText(id = txtDate).After call the screen,I tried to use the example of Toast for date input in Edittext :
Toast.makeText(getApplicationContext(),
day + "/" + month + "/" + year, Toast.LENGTH_LONG)
.show();
I changed by :
txtDate.setText(day + "/" + month + "/" + year);
It did not work. What should be done?
Code :
public class ScreenCalendar extends Activity {
EditText txtDate;
CalendarView calendar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.screen_calendar);
txtDate = (EditText) findViewById(R.id.txtDate);
// initializes the calendarview
initializeCalendar();
}
@SuppressLint("NewApi")
public void initializeCalendar() {
calendar = (CalendarView) findViewById(R.id.calendar);
// sets whether to show the week number.
calendar.setShowWeekNumber(false);
// sets the first day of week according to Calendar.
// here we set Monday as the first day of the Calendar
calendar.setFirstDayOfWeek(2);
// The background color for the selected week.
calendar.setSelectedWeekBackgroundColor(getResources().getColor(
R.color.green));
// sets the color for the dates of an unfocused month.
calendar.setUnfocusedMonthDateColor(getResources().getColor(
R.color.transparent));
// sets the color for the separator line between weeks.
calendar.setWeekSeparatorLineColor(getResources().getColor(
R.color.transparent));
// sets the color for the vertical bar shown at the beginning and at the
// end of the selected date.
calendar.setSelectedDateVerticalBar(R.color.darkgreen);
// sets the listener to be notified upon selected date change.
calendar.setOnDateChangeListener(new OnDateChangeListener() {
// show the selected date as a toast
@Override
public void onSelectedDayChange(CalendarView view, int year,
int month, int day) {
startActivity(new Intent(getBaseContext(), Event.class));
/*Toast.makeText(getApplicationContext(),
day + "/" + month + "/" + year, Toast.LENGTH_LONG)
.show();*/
txtDate.setText(day + "/" + month + "/" + year);
}
});
Code:
public class Event extends Activity implements OnClickListener {
EditText txtDate, txtTime;
// Variable for storing current date and time
private int mYear, mMonth, mDay, mHour, mMinute;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.event);
txtDate = (EditText) findViewById(R.id.txtDate);
txtTime = (EditText) findViewById(R.id.txtTime);
txtDate.setOnClickListener(this);
txtTime.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if (v == txtDate) {
// Process to get Current Date
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
// Launch Date Picker Dialog
DatePickerDialog dpd = new DatePickerDialog(this,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
txtDate.setText(dayOfMonth + "-"
+ (monthOfYear + 1) + "-" + year);
}
}, mYear, mMonth, mDay);
dpd.show();
}
if (v == txtTime) {
// Process to get Current Time
final Calendar c = Calendar.getInstance();
mHour = c.get(Calendar.HOUR_OF_DAY);
mMinute = c.get(Calendar.MINUTE);
// Launch Time Picker Dialog
TimePickerDialog tpd = new TimePickerDialog(this,
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
// Display Selected time in textbox
txtTime.setText(hourOfDay + ":" + minute);
}
}, mHour, mMinute, false);
tpd.show();
}
}
}

The setText() method of an EditText can be seen here .
public void setText (CharSequence text, TextView.BufferType type)
Try this:
txtDate.setText(day + "/" + month + "/" + year, TextView.BufferType.EDITABLE);
Edit:
Your logcat shows that txtDate is null when you try to call setText() on it.
