This is what my LinearLayout (horizontal) row looks like:

I want the text of the checkbox to be on one line; The buttons don't have to be that wide - they'll still have plenty of space with the checkbox text lengthened a bit. What in my XML:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <CheckBox
        android:id="@+id/ckbxAllow_New_Items"
        android:layout_width="0dip"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:checked="true"
        android:text="@string/checkbox_Allow_New_Items" />

    <Button
        android:id="@+id/btnOK"
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="@string/button_OK" />

    <Button
        android:id="@+id/btnCancel"
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="@string/button_Cancel" />

</LinearLayout>

...needs to change in order to force my checkbox text not to wrap?

UPDATE

Following Der Golem's suggestion by adding this:

android:lines="1"

...and also changing layout_weight for the checkbox from 1 to 2 (set to 1 for the buttons) gave me what I wanted:
