this question relates to this one: android.R.simple_spinner_item
Since I can't comment because of low reputation, I have an additional question:
If I copy&paste the android.R.simple_spinner_item layout, I get an error on
android:layout_height="?android:attr/dropdownListPreferredItemHeight" saying "error: Error: Attribute is not public. (at 'layout_height' with value '?android:attr/dropdownListPreferredItemHeight')."
I just added android:gravity="right" to get the spinner_item alignment to the right side.
How can I solve this error?

Spinners provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one.
For adding item in Spinner, you can do one thing, try to create an adapter and then add/remove items into the adapter, then you can easily bind that adapter to spinner by using setAdapter() method.
ArrayAdapter is the most commonly used adapter in android. When you have a list of single type items which are stored in an array you can use ArrayAdapter. Likewise, if you have a list of phone numbers, names, or cities. ArrayAdapter has a layout with a single TextView.
ImageView class is used to display any kind of image resource in the android application either it can be android. graphics. Bitmap or android. graphics. drawable.
Seems to work for me if you don't prefix it with android, like so:
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/text1" style="?android:attr/spinnerDropDownItemStyle" android:singleLine="true" android:layout_width="match_parent" android:layout_height="?attr/dropdownListPreferredItemHeight" android:ellipsize="marquee"/> If you love us?
