ViewPostIme pointer 1/0

Question

I have the following code with no compilation errors, just resulting in an infinite loop... I don't get where the problem is.

When I click the Button, I want to create an object using the values entered in the edittexts and pass them to another activity. But instead, I get a loop.

Each spinner is populated using a string-array from resources/strings. I had some difficulties getting the values here, because at the spinner spTipUtilizator when "Profesor" is selected, I want spGrupa to be disabled, and when "Student" is selected, I want spdept to be disabled, but also this doesn't work. And based on that option will be chosen the next activity which will be opened after clicking the button.

Also, why doesn't it work to set the default date in my calendar? I tried multiple things found here, but none of them worked for me. My Android Studio doesn't show DatePicker, which I would prefer, only that Calendar.

Answer 1

You shouldn't create the OnItemSelectedListener inside the OnClickListener for your sign in button, instead you have to create it outside and save the selected option in a variable.

Then when the user clicks your sign in button, you check witch option was selected and start the correct Activity.

Looking at your code, you could simply save the intent to the next activity, and when the user clicks the button just start the Activity on that intent.

I've put a check for nullity before trying to start that intent, and you could show the user some dialog or Toast if no valid option was selected.
