Alert dialog buttons are too close

Question

I see this thing with Alert dialog's buttons touching (there is no space between them).

This happens regardless of the theme being used.. Code:

builder.setTitle(R.string.sign_in_title);
builder.setCancelable(false)
        .setPositiveButton(R.string.sign_in, (dialog, id) -> {
            //Todo
        })
        .setNegativeButton(R.string.cancel, (dialog, id) -> dialog.cancel());
builder.create().show();

App theme inherits:

 <style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">

I tried to build a minimum project setup just with Alert.Dialog and I see the same thing..

Any ideas what is going on or how to fix it?

Edit: I'm aware that I can change Alert's theme to yield different results but that also implies that I won't have uniform buttons across my app (i.e. green filled with white text)

Answer 1

Just change imported class for AlertDialog from Supported Library:

import androidx.appcompat.app.AlertDialog;

instead of

import android.app.AlertDialog;

Thank you.
