Format Edittext Android

Validation date in EditText for android while user is clicking
  • EditText has an attribute called android:inputType. Providing android:inputType with value phone can display numbered keyboard when the EditText gets focus. Create an Android Project and replace layout (activitymain.xml) and Kotlin file (MainActivity.kt) with the following code.
  • 2) Now initialize Edit Text in your java file. Here I have used the method DateDialog to open the calendar popup and select the date. Here I have used the method DateDialog to.
EditTextDateValidation.java
//SOURCE: http://stackoverflow.com/questions/16889502/how-to-mask-an-edittext-to-show-the-dd-mm-yyyy-date-format
EditText date;
date = (EditText)findViewById(R.id.whichdate);
date.addTextChangedListener(tw);
TextWatcher tw =newTextWatcher() {
privateString current ='';
privateString ddmmyyyy ='DDMMYYYY';
privateCalendar cal =Calendar.getInstance();
When user changes text of the EditText
@Override
publicvoid onTextChanged(CharSequence s, int start, int before, int count) {
if (!s.toString().equals(current)) {
String clean = s.toString().replaceAll('[^d.]', '');
String cleanC = current.replaceAll('[^d.]', '');
int cl = clean.length();
int sel = cl;
for (int i =2; i <= cl && i <6; i +=2) {
sel++;
}
//Fix for pressing delete next to a forward slash
if (clean.equals(cleanC)) sel--;
if (clean.length() <8){
clean = clean + ddmmyyyy.substring(clean.length());
}else{
//This part makes sure that when we finish entering numbers
//the date is correct, fixing it otherwise
int day =Integer.parseInt(clean.substring(0,2));
int mon =Integer.parseInt(clean.substring(2,4));
int year =Integer.parseInt(clean.substring(4,8));
if(mon >12) mon =12;
cal.set(Calendar.MONTH, mon-1);
year = (year<1900)?1900:(year>2100)?2100:year;
cal.set(Calendar.YEAR, year);
// ^ first set year for the line below to work correctly
//with leap years - otherwise, date e.g. 29/02/2012
//would be automatically corrected to 28/02/2012
day = (day > cal.getActualMaximum(Calendar.DATE))? cal.getActualMaximum(Calendar.DATE):day;
clean =String.format('%02d%02d%02d',day, mon, year);
}
clean =String.format('%s/%s/%s', clean.substring(0, 2),
clean.substring(2, 4),
clean.substring(4, 8));
sel = sel <0?0: sel;
current = clean;
date.setText(current);
date.setSelection(sel < current.length() ? sel : current.length());
}
}
We also implement the other two functions because we have to
@Override
publicvoid beforeTextChanged(CharSequence s, int start, int count, int after) {}
@Override
publicvoid afterTextChanged(Editable s) {}
};

Android Show DatePicker on EditText Click Example. Following is the example of open or popup datepicker dialog when we click on EditText control and get the selected date value on Button click in the android application. Create a new android application using android studio and give names as DatePickerExample. In Android, EditText is a standard entry widget in android apps. It is an overlay over TextView that configures itself to be editable. EditText is a subclass of TextView with text editing operations. We often use EditText in our applications in order to provide an input or text field, especially in forms.
