Change Datepicker Calendar Size In Android Programmatically

I'm doing an Android application and I have to show a DatePickerDialog. The fact is that the application will be on a device with a smart screen and the calendar doesn't fit in it.

Solution 1:

you can change width and height DatePickerDialog programmatically, you just use WindowManager.LayoutParams params = dateForm.getWindow().getAttributes(); see this example:

        final Calendar c = Calendar.getInstance();

        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        DatePickerDialog dateForm = new DatePickerDialog(this, R.style.AppTheme, new DatePickerDialog.OnDateSetListener() {
            @Override
            publicvoidonDateSet(DatePicker datePicker, int year, int monthOfYear, int dayOfMonth) {

            }
        }, year, month, day);

        DatePicker dp = dateForm.getDatePicker();

        WindowManager.LayoutParams params = dateForm.getWindow().getAttributes();

        params.gravity = Gravity.TOP;
//        params.x = 0; // locationByX;//        params.y = 0; // locationByY;params.width = 600; // dialogWidth;//        params.height = 1000; // dialogHeight;

        dateForm.getWindow().setAttributes(params);

        dateForm.show();

//        dp.setScaleY(Float.parseFloat("0.7"));//        dp.setScaleX(Float.parseFloat("0.7"));

Solution 2:

Try this

dateForm.getWindow().setLayout(width,height)

width & height specific as device resolution size maintain dimension file or use SDP Library for that.

or for that specific resolution use AlertDialog.THEME_HOLO_LIGHT as below :

DatePickerDialogdateForm=newDatePickerDialog(ViewForm.this, AlertDialog.THEME_HOLO_LIGHT, newDatePickerDialog.OnDateSetListener() {}

Solution 3:

Following code can be used:

if(datePickerDialog.getWindow()!=null) {
        datePickerDialog.getWindow().setLayout(WindowManager.LayoutParams.WRAP_CONTENT, 
        WindowManager.LayoutParams.WRAP_CONTENT);datePickerDialog.getWindow().setGravity(Gravity.CENTER);
  }

Instead of LayoutParams.WRAP_CONTENT, You can set custom width and height as well.
