25 /**
26  * Ultra-simple subclass of EditTextPreference that allows the "title" to wrap
27  * onto multiple lines.
28  *
29  * (By default, the title of an EditTextPreference is singleLine="true"; see
30  * preference_holo.xml under frameworks/base.  But in the "Respond via SMS"
31  * settings UI we want titles to be multi-line, since the customized messages
32  * might be fairly long, and should be able to wrap.)
33  *
34  * TODO: This is pretty cumbersome; it would be nicer for the framework to
35  * either allow modifying the title's attributes in XML, or at least provide
36  * some way from Java (given an EditTextPreference) to reach inside and get a
37  * handle to the "title" TextView.
38  *
39  * TODO: Also, it would reduce clutter if this could be an inner class in
40  * RespondViaSmsManager.java, but then there would be no way to reference the
41  * class from XML.  That's because
42  *    <com.android.server.telecom.MultiLineTitleEditTextPreference ... />
43  * isn't valid XML syntax due to the "$" character.  And Preference
44  * elements don't have a "class" attribute, so you can't do something like
45  * <view class="com.android.server.telecom.Foo$Bar"> as you can with regular views.
