对于标题和消息，您可以使用：

    <style name="MaterialAlertDialog__Center" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
        <item name="materialAlertDialogTitlePanelStyle">@style/Title.Panel.Center</item>
        <item name="materialAlertDialogBodyTextStyle">@style/Message.Center</item>
    </style>

    <style name="Title.Panel.Center" parent="MaterialAlertDialog.MaterialComponents.Title.Panel">
        <item name="android:gravity">center_horizontal</item>
    </style>

    <style name="Message.Center" parent="MaterialAlertDialog.MaterialComponents.Body.Text">
        <item name="android:gravity">center_horizontal</item>
    </style>

和：

MaterialAlertDialogBuilder(this, R.style.MaterialAlertDialog_Center)
                .setTitle("Message")
                ..
                .show()
