问题
I have long text that I want to put in a few, but not all, items in a spinner. Tried using the answer here but was not able to get it to work. I created and saved multiline_spinner_dropdown_item.xml in res/layout directory but still get an error "multiline_spinner_dropdown_item cannot be resolved" in Eclipse.

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="?android:attr/spinnerItemStyle"
android:singleLine="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:textColor="#ffffff"/>
Use this textview in your spinner adapter in place of the android default textview you are using in .setAdapter method of the Spinner. see below R.layout.spinner_textview textview is this textview i have posted above.
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getApplicationContext(),
R.array.Array,
R.layout.spinner_textview);
adapter.setDropDownViewResource (android.R.layout.simple_spinner_dropdown_item);
