+     42dp | STRING TO SHOW                                             MIC |
+          +................................................................+
+
+     The microphone icon is supposed to be 24dp x 24dp.  To allow a bigger
+     touch target, we make it 42dp by adding 9dp of padding to each side.
+     Because there is supposed to be a 12dp in between the microphone and
+     the box, we use a total of 12dp for the end padding.
