Android Spinner validation

Question

I need to validate selected item of Spinner in Android.

I tried the following code, but it's not working.

if (Spinner1.getSelectedItem().toString().trim() == "Pick one") {
    Toast.makeText(CallWs.this, "Error", Toast.LENGTH_SHORT).show();
}

What is wrong with the code, and how can i fix it?

Answer 1

Use .equals or .equalsIgnoreCase to compare two strings in java/android instead of ==.

Try this

if (Spinner1.getSelectedItem().toString().trim().equals("Pick one")) {
    Toast.makeText(CallWs.this, "Error", Toast.LENGTH_SHORT).show();
}

Answer 2

Simply use this.

else if (Spinner1.getSelectedItem().toString().trim().equalsIgnoreCase("Pick one")) {
            Toast.makeText(CallWs.this, "Error",
                    Toast.LENGTH_SHORT).show();
