How to find whether if user clicked spinner in Android?

Question

In my application I am creating spinner dynamically in code.I want to force user to click on Spinner and change its value/content. Otherwise user should not be able to go to next screen by clicking Next button.

How to do that in Android? Anybody has any idea?

Thanks in Advance.

Answer 1

Let the Spinner's first value be something like "-please select-".

when the user clicks on the next button perform validation and check whether the value of the selectedItem in the spinner is "-please select-" and if yes, then display a toast and ask the the user to select something from the spinner.

you need code, let me know.

Answer 2

you can use this:

 if (spin.getSelectedItemPosition() < 0) {//Do something}

this means user hasn't selected anything.

Answer 3

Use this code for checking the spinner item is selected or not.

both flags take at class level (Globally).

Boolean temp = false;
Boolean check = false;


spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub
            if(temp){
                check = true;
            }
            temp = true;
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
            check = false;
        }
});

button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            if(check){

                //perform when user select spinner item             
            }else{

                //put Dialog for alert please select spinner item 

            }
        }
}
