How to add items to a spinner in Android?
(11 answers)
Closed 2 years ago.
I have a spinner where the contents are from an Array in Strings.xml. However I would like to be able to let the user add items to the array. Can anyone help and let me know if there is a way to do this?
Many thanks
ArrayAdapter has a method add(object) as seen here: ArrayAdapter | Android Developer
For example:
fun addItem(item: T) {
arrayAdapter.add(item)
// Refreshes the view to reflect the changes applied to arrayAdapter
arrayAdapter.notifyDataSetChanged()
}

Determine whether an array contains a value [duplicate]
(18 answers)
Closed 7 years ago.
I have array of name:
$scope.myArray with some values.
Now I want to check an Item is present in array or not,
If it is not present then I want to push that item into array and If that item is already in array then I don't want to push it.
Please tell me how to do this ?
if($scope.myArray.indexOf(item) === -1) {
$scope.myArray.push(item)
}
You can read about indexOf for more details. Also, checkout underscore js for some readily available functions.

I want to do this with a shorter operation. How can i do it? Thank you
data = [Test1;Test2;Test3;Test4;Test5;Test6;Test7;---- until-----;Test36];
You can solve this using eval, however the use of this function is usually not recommended:
eval(['data=[', sprintf('Test%d;',(1:36)),'];'])
Rather follow Dan's comment and don't create seperate matrices.
You can use the eval command to do this:
Test1=magic(5);
Test2=magic(5);
data=cell.empty(2,0);
for ii=1:2
data{ii} = eval(sprintf('Test%d', ii));
end

How to Segue Randomly to ViewControllers in Swift? [closed]
(1 answer)
Closed 7 years ago.
I'm trying to make an array in swift of segues so that I can switch to a random view controller via pressing a button.
You can more reasonably maintain an array of strings that could represent the segue.identifier.

AuthComponent: Difference between allowedActions and allow()?
What is the difference between using the method
$this->Auth->allow()
and setting the variable
$this->Auth->allowedActions ?
I can't find any information about setting the allowedActions array where I expected to find it (http://book.cakephp.org/view/1251/Setting-Auth-Component-Variables) - but it exists in the API at http://api13.cakephp.org/class/auth-component.
Can someone please explain which different circumstances I should use them?
