How to validate date in dd/mm/yyyy format in editext in android?

Question

I have two edittexts. I want to validate date entered in first edittext when I switch to next edittext... Is it possible? I want to validate in dd/mm/yyyy format strictly.. please help me.. i searched and tried also but not get such a solution..

what effort you put for this? tell more about your date format — Sree, Mar 26 '14 at 11:43
Better to use [DatepickerDialog](http://stackoverflow.com/questions/18267091/open-a-datepickerdialog-on-click-of-edittext-and-set-the-date-value-android) instead of Edittext for date inputs..' — Chirag Ghori, Mar 26 '14 at 11:43

Step 1

       youredittextname.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence s, int start, int before,
                    int count) {
                // TODO Auto-generated method stub
            }
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
                // TODO Auto-generated method stub
            }
            @Override
            public void afterTextChanged(Editable s) {
                // TODO Auto-generated method stub
                Is_Valid_date(name); // pass your EditText Obj here.
            }
        });

Step 2

Write a function.

       public void Is_Valid_date(EditText edt) throws NumberFormatException {
        if (edt.getText().toString().length() <= 0) {
            edt.setError("Accept number Only.");
            valid_name = null;
        } else if (check your date format using simpledate format) {
            edt.setError("Accept Alphabets Only.");
            valid_name = null;
        } else {
            valid_name = edt.getText().toString();
        }

    }

Use interface TextWatcher in Android. You have to override its methods:

In onTextChanged() limit the length of text
In afterTextChanged() use some good regular expression for date validation. It will be available from Google.
