<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    style="?android:attr/spinnerItemStyle"
    android:layout_width="fill_parent"
    android:layout_height="60dp"
    android:textSize="20dp"
    android:gravity="center"
    android:text="Testing" />
    
//not sure if TextView can be encompassed in Relative/Linear Layout or not

- Implement AdapterView.OnItemSelectedListener -> generates two methods

Spinner optionsSpinner;
String[] options = { "Option 1", "Option 2"};

//to modify dropdown settings, create a custom simple_spinner_item
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, options);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

optionsSpinner.setAdapter(adapter);
optionsSpinner.setOnItemSelectedListener(this);

@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {

    //changes color of selected item only
    TextView text = (TextView)view;
    text.setTextColor(Color.BLUE);

    if (i == 0)
        //perform action 1
        
    if (i == 1)
        //perform action 2
}
