    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_spinner);

    spinner = (Spinner)findViewById(R.id.spinner);
    ArrayAdapter<String> adapter;
    adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item,sports);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);
}

@Override

Well, obviously

java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.widget.Spinner

Means that you have a LinearLayout instead of Spinner with id "@+id/spinner in activity_spinner

In your SpinnerActivity,LinearLayout can not be cast Spinner.Which means you wirte LinearLayout in activity_spinner.xml but use spinner = (Spinner)findViewById(R.id.spinner); instead .

If you are sure that it is spinner and you have recently made change to your layout file then just clean your project and run again will solve your problem. Sometimes modifying the layout file will not instantly reflect to R file and gives ClassCastException.
