checkbox

问题 I am using ListView with CheckBox . I have selected only one CheckBox but it's automatically selected into Multiple Rows using ScrollView . Sample Code (This Code is working Perfectly) holder.checkbox.setOnClickListener( new OnClickListener() { public void onClick( View v ) { CheckBox cb = ( CheckBox ) v; if ( cb.isChecked() ) { test[position] = true; holder.checkbox.setChecked(test[position]); } else { test[position] = false; holder.checkbox.setChecked(test[position]); } } }); holder

问题 I am trying to customize the checkboxes and radios in Django using bootstrap class. However, it has not worked. I already tried to insert the bootstrap class in forms.py with widgets and attrs : custom-control custom-radio custom-control-inline custom-control-input custom-control-label My code: models.py Y = 1 N = 2 YN = ( (Y, 'yes'), (N, 'no'),) class Prop(models.Model): yesorno = models.IntegerField(choices=YN, default=Y, verbose_name='Label...') forms.py class PropForm(forms.ModelForm):

问题 I am passing multiple form fields which are optional, but which need to be associated with a user. Python's cgi.FormDict and cgi.FieldStorage both eliminate blank entries, so items get shifted "up" and associated with the wrong user.

Simplified form code: <input type="text" name="user" /> <input type="text" name="email" /> <input type="text" name="phone" /> <input type="checkbox" value="MailingList1"

问题 I got some difficulties with one point since 1 week, I have 2 arrays, and I want to auto select checkboxes by retrieving the value inside one of the array. First of all, I have a loop which create some checkboxes based on the first array choices[]. Every time I check one a checkbox, a text field is updated with a separator.

问题 I have a ListView that has 649 entries. Each View in the list has two LinearLayouts, an ImageView, a few TextViews, and a CheckBox. I currently have code to go through all the CheckBoxes and count them, and more code to figure out which ones are checked so I can use them. However, whenever I check one of the CheckBoxes, every seventh CheckBox above and below it magically become checked as well. The method to count the checked boxes returns the number I actually checked, but the method to get

问题 I have the following code which enables a button when the checkbox is checked. http://jsfiddle.net/ERfWz/1/ The following is a snippet from the code I have in my HTML page. It's much the same however for some reason it's not working.
