There are many kinds of Android controls, one of which is a spinner control, which is actually a drop-down display list. The spinner is located under the Android.widget package, displaying only the elements selected by the user each time, and when the user clicks again, the selection list is ejected for the user to select, and the elements from the selection list are also from the adapter.

There is a question about how to customize the menu popped out. Of course, I didn't tell you in the book. They didn't know exactly what the two layout associations related to arrayadapter are. Just put a code in the column. I was dizzy, so I wrote code and verified my speculation. After a long time, I "oh" and solved my doubts. Th

If you apply Simple_spinner_item or Simple_spinner_dropdown_item, then directly in spinnerandroid:gravity= "Center"It is impossible to center the text in the spinner.This is because the text in the spinner is actually set in the TextView (refer to: HTTP://WWW.DOUBAN.COM/NOTE/483280526/?TYPE=LIKE#SEP).At first I thought of one way:Nesting a linearlayout outside the spinner, setting the android:gravity= "cent

From the previous lessons, we can see that listview is used to display a long list and occupy the entire screen (listactivity ). However, sometimes you may need other similar views, so that you do not have to fill the entire screen. In this case, you should use the spinner control. The spinner displays a piece of information in the list at a time and allows you to select. The following describes how to us

The spinner style that comes with the Android system is far from satisfying the spinner UI style requirements in our actual development process, so we definitely need to modify our spinner style to suit the style of the application.
