问题 In spinner xml, I'm using: android:entries="@array/cars" where cars is list of numeric items. The spinner automatically align values to left, and I can't find in xml/code how to change it. 回答1: You have to use a custom view here to give alignment to the Spinner values. Create a CustomView like this answer has created and add android:gravity to the TextView as right . UPDATE: Set the CustomView to your adapter using adapter.setDropDownViewResource(android.R.layout.your_custom_created_view);
