radio-button

问题 I would like to ask if there are examples out there on how to implement radio-button options on an iPhone app. I find the Picker View quite big for a simple selection feature. I'm not sure if Apple excluded radio buttons on purpose, and whether if it is better to simply use a Picker View from a usability / user experience point-of-view. 回答1: I have some thoughts on how the best radio button implementation should look like. It can be based on UIButton class and use it's 'selected' state to

问题 I have tried this code..It will display three radio buttons in a single row when the emulator starts. But I need a button event for this. i.e; if I click the button, it should ask for number of radio buttons. then If I give the count, it must display the radio buttons based on the count given. For example, If I give the count as 3, it must display the three radio buttons in a single row. Your help is highly appreciated. Thanks in advance. public class MyActivity extends Activity { /** *

问题 I am developing an application in which I need to implement radio buttons in list view. I want to implement a list view having one radio button and two text view in each row. And one button "Ok" below listview. What I have done is I created a list view and a custom adapter. The code of listview is as: <ListView android:id="@+id/listview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:cacheColorHint="#00000000" android:overScrollMode="never" tools:ignore=

问题 I've got code similar to the following... <p><label>Do you have buffet facilities?</label> <asp:RadioButtonList ID="blnBuffetMealFacilities:chk" runat="server"> <asp:ListItem Text="Yes" Value="1"></asp:ListItem> <asp:ListItem Text="No" Value="0"></asp:ListItem> </asp:RadioButtonList></p> <div id="HasBuffet"> <p><label>What is the capacity for the buffet?</label> <asp:RadioButtonList ID="radBuffetCapacity" runat="server"> <asp:ListItem Text="Suitable for upto 30 guests" value="0 to 30"></asp

问题 Is it possible to add a little bit of space between a RadioButton and the label while still using Android's built-in components? By default the text looks a little scrunched. <RadioButton android:id="@+id/rb1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="My Text"/> I've tried a couple of things: Specifying margin and padding seem to add space around the entire element (button and text, together). That makes sense, but doesn't do what I need. Creating a

问题 I'm following this answer on how to databind enums (ints in my case) to RadioButtons, but if I've got several TabItems each with 10x10 grids of RadioButtons, is there any way to get rid of some of that boilerplate? As is, each RadioButton has to have all this info with it: <RadioButton IsChecked="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=FavoriteColor, Converter={StaticResource IntToBoolConverter}, Mode=TwoWay, ConverterParameter=5}" Content=

问题 I know that WebForms has a RadioButtonList control, but I can't find one for WinForms . What I need is to have 3 RadioButtons grouped together, so that only 1 can be selected at a time. I'm finding that I have to do this through code, which is a pain. Am I just not seeing RadioButtonList somewhere, or does it really not exist in WinForms ? 回答1: Apparently not. You can group three RadioButtons together using a GroupBox or a Panel as is done here. 回答2: If you just want to group radio buttons,

问题 About a month ago Mitt’s question went unanswered. Sadly, I’m running into the same situation now. http://api.jquery.com/change/#comment-133939395 Here’s the situation: I’m using jQuery to capture the changes in a radio button. When the radio button is selected I enable an edit box. When the radio button is de-selected, I would like the edit box to be disabled. The enabling works.
