/**

 * Ultra-simple subclass of EditTextPreference that allows the "title" to wrap

 * onto multiple lines.

 *

 * (By default, the title of an EditTextPreference is singleLine="true"; see

 * preference_holo.xml under frameworks/base.  But in the "Respond via SMS"

 * settings UI we want titles to be multi-line, since the customized messages

 * might be fairly long, and should be able to wrap.)

 *

 * TODO: This is pretty cumbersome; it would be nicer for the framework to

 * either allow modifying the title's attributes in XML, or at least provide

 * some way from Java (given an EditTextPreference) to reach inside and get a

 * handle to the "title" TextView.

 *

 * TODO: Also, it would reduce clutter if this could be an inner class in

 * RespondViaSmsManager.java, but then there would be no way to reference the

 * class from XML.  That's because

 *    <com.android.server.telecom.MultiLineTitleEditTextPreference ... />

 * isn't valid XML syntax due to the "$" character.  And Preference

 * elements don't have a "class" attribute, so you can't do something like

 * <view class="com.android.server.telecom.Foo$Bar"> as you can with regular views.
