android-spinner

问题 Working in fragments, I'm trying to return a value determined from selecting an item in a spinner and I can't make it work. The Toast notification inside the method isn't even working, it seems like the problem is within the method. How can I fix this? public Spinner districtSpinner, countySpinner; public int selectedDistrict; are the variables used. Here's my parent spinner method, districtSpinner() public void districtSpinner() { ArrayAdapter<String> Dadapter = new ArrayAdapter<String>

问题 After using Actionbar i thought that what if same widget could be available for native android platform. I dont know if we can grab the styles and apply it to native widgets from actionbar apis(compatibility library v4) or not. What i am asking is spinner widget like below which is mostly used in actionbar. Check for dropdown widget. Is it possible to use the same in native like in Listview ? Many thanks. 回答1: adapter = new ArrayAdapter<CharSequence>(this,android.R.layout.simple_spinner_item,

问题 Currently I'm developing an Android application and we are using the action bar with a spinner navigation for a specific view. The main problem is: The user should be able to reselect an action bar spinner item, after he already selected this item. Android seems to prevent a second selection of an action bar spinner item. Is there a way to be able to select an item more than once or is there a completely other way to achieve this behavior? 回答1: Ok, now after many attempts I found a working

问题 I need to animate an icon of an arrow when opening and closing a spinner in Android. I can rotate the arrow when opening the spinner: I just put a setOnTouchListener on the Spinner . The problem comes, when the dropdown is closed, or hidden, because I don't know how to set a listener or something like that on that action. Anybody has an idea about how to do this, if possible? Thanks a lot in advance. 回答1: I do not know why Google can not do it for so long, but you can solve the problem this

问题 I'm kind of new to android, so sorry in advance if this is a silly question. I wanted to get some guesses on how gmail (or other apps) accomplish their custom spinner title, as shown in the picture: I am mainly interested in the "Recent" text. How do they achieve this kind of customization? Thanks in advance. 回答1: you just need to implement popup window http://developer.android.com/reference/android/widget/PopupWindow.html example with source code http://www.androidhub4you.com/2012/07/how-to

问题 I've implemeted spinner like here . And now I want to place spinner in ActionBar (setting spinner as CustomView to actionBar) but it doesn't appear there :( Spinner spinner = (Spinner) findViewById(R.id.planets_spinner); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.planets_array, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); actionBar.setCustomView

问题 I use a custom array adapter for a spinner. However, when selecting an item in the dropdown list, the dropdown list stays there, and the spinner doesn't get updated, which is misbehaviour (compared to using a generic array adapter with string). This is the custom class. Am I missing anything? thanks. public class CalendarNameAdapter extends ArrayAdapter<AgendaLogic.ExternalCalendarInfo> { Context mContext ; ArrayList<AgendaLogic.ExternalCalendarInfo> mCalendarLayers; public

问题 I got a custom spinner, and I'm trying to replace the 9-patch background / the triangle in the DropDownSelector. I just can't get it to work right though. I end up with (the white box is a test asset): the new 9 patch gets shown, but it messes up the padding, and it looks like a Spinner inside a Spinner. Here's what it looks like without the 9 patch added: This is what I want it to look like, but then with the new 9patch instead of the old one, not the Spinner in Spinner effect. Here's my

问题 I have a spinner on my actionbar. It is a menuitem (not a navigation mode). It gives me back a nullpointerexception on the lines where i call a method from spinnerNumber. I think i'm doing something wrong with the xml or maybe i shouldn't initialize it on OnCreateOptionMenu (but i think that calling it on OnCreate, when the menu xml isn't still inflated, is not correct either). act_main.xml: <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id
