Answer 1

Check whether you called the id correctly or not? When I was working when improper id was called this exception used to arise. For eg In TextView, findViewById(R.id.textView1) but in xml file we may have set it to textView2.

Answer 2

Try this :

if (spinner1.getSelectedItem().toString().equals("Dollars") && spinner2.getSelectedItem().toString().equals("Euros")
...

getSelectedItem() returns an Object . info . So you have to get the corresponding string first. Then java compares strings using equals().

Answer 3

if (spinner1.getSelectedItem()=="Dollars" && spinner2.getSelectedItem()=="Euros") {

You can't compare Strings like that. You have to use the equals() method to compare them. Use this:

if (spinner1.getSelectedItem().toString().equals("Dollars") && spinner2.getSelectedItem().toString().equals("Euros")) {}
