Question

Right now i am consuming one web service in android.That web service is having two input values
namely 01/01/2012 and 07/07/2012 respectively.

After clicking the invoke button and after providing these as input values,my project will show some bar-charts.Well its working fine.Here i am using two edit-text boxes for getting those input values.

But i would like to use Date-picker widget instead of using edit-text boxes.So i have dragged the date-picker widget and i did some code.

But now the problem is, the input values are fully off numeric and backslash right?
But in the date-picker widget it showing the input values in the combination of characters and numeric,but i need to use only the date-picker widget.

The date-picker widget is in this format dd-mm-yyyy eg:- 01-jan-1990

but i need to convert the above format in to 01/01/1990. How to do this?

please find my sources for references

Any idea?

Thanks for your precious time!..

How about this:

You keep the text fields and when the textfeild is selected a DateTime Picker dialog appears, and the textfield retains the datetime format.

final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
updateDisplay();

and in the update display method:

private void updateDisplay() {
    checkdate.setText(
            new StringBuilder()
            // Month is 0 based so add 1
            .append(mMonth + 1).append("-")
            .append(mDay).append("-")
            .append(mYear).append(" "));
}

Also add to the Activity

@Override
protected Dialog onCreateDialog(int id) {
    // TODO Auto-generated method stub
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this,
                mDateSetListener,
                mYear, mMonth, mDay);
 }
}
@Override
protected void onPrepareDialog(int id, Dialog dialog) {
    // TODO Auto-generated method stub
    switch (id) {
    case DATE_DIALOG_ID:
        ((DatePickerDialog) dialog).updateDate(mYear, mMonth, mDay);
        break;
    }
}
private DatePickerDialog.OnDateSetListener mDateSetListener =
    new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {
        // TODO Auto-generated method stub
        mYear = year;
        mMonth = monthOfYear;
        mDay = dayOfMonth;
        updateDisplay();
    }
};

And add the Focus listener to the textfield

textfield1.setOnFocusChangeListener(new OnFocusChangeListener(){
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            // TODO Auto-generated method stub
            if(hasFocus){
                showDialog(DATE_DIALOG_ID);
            }
        }
    });

Hope its what you need.
