The answer stated there is: You will have to set the Click listener on the underlying view (normally a TextView with id: android.R

But I can't find this option when defining my layout in XML. Did I just miss it, or is this not possible in XML? 回答1: No, according to the reference found here this is not possible. There is no corresponding XML attribute listed. Like other things as setting 24h mode for a timepicker, which is not possible in XML. 回答2:

I would like to set the initial value of the spinner via the 2-way databinding on android:selectedItemPosition . The spinner entries are initialised by the ViewModel and are populated correctly, hence databinding appears to be working correctly. The problem is with the 2-way binding of selectedItemPosition . The variable is initialised to 5 by the ViewModel but the spinner's selected item remains at 0 (the first item). When

I have a Spinner with an ArrayAdapter that feeds Values into it. The layout for this views looks something like this: <TextView android:text="Household Income: " android:layout_width="wrap_content" android:layout_height="fill_parent" android:gravity="center_vertical" /> <Spinner android:id="@+id/incomespinner" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="2dip" /> The Problem is that the text is to long for the view and the result is a very very ugly spinner. As can be seen in the screenshot: (source: janusz at janusz.de ) I tried to pass the Id of my

The user of our app should be able to adjust a floating point number. At the moment, I filled an ArrayAdapter with all possible values and attached it to a spinner. This solution doesn't really meet our expectations, since the spinner dropdown box is way too tall. Is there a better way? I was looking at Numberpicker - but this seems to work only with Integer values. Any ideas? Thanks! Zombie NumberPicker is not just for integers.. Even you can use Floats String etc. see this and read about it. for tutorials : http://gafurbabu.wordpress.com/2012/03/29/android-number-picker-dialog/ And I had

I have a spinner widget in my activity which lets users pick a list name. Normally, the function of the spinner is to switch between lists but for a couple of instances, I swap out the selection change listener to perform a different function with the same list of options. Once the selection has been made, the old listener is restored and life goes on. This is a bad and buggy arrangement. Instead, I would like to have a function that just takes a selection listener and some other parameters and shows a popup list that's populated by the same cursor (or and identical cursor) as the spinner,
