I have a TextView set to ellipsize but when I put the text in it doesn\'t do so. Any ideas?
android:layout_width="wrap_content"
will allow the TextView to expand as long as it needs to (including running off the screen). To make it ellipsize, you're going to have to set a width as citizen conn recommended, preferably with android:layout_width="fill_parent" instead of an absolute value.
Additional hints: You'll also want to set the maxLines of the TextView (probably to 1), and to get the actual ellipsis ("...") to appear, you'll probably also have to set
android:scrollHorizontally="true"
