Android ListView mit schnellem Bildlauf und alphabetischem Abschnittsindex

Wie füge ich Testview hinzu, wenn Sie einen Buchstaben im rechten Alphabetfeld wie in Bildern gezeigt berühren? Könnten Sie mir bitte helfen? Unten ist mein Code. 

Im Detail suche ich ein Beispiel genau wie in der Abbildung unten. Momentan habe ich die Daten sortiert. Wenn ich auf das rechte Alphabetfeld klicke, werden die Daten richtig angezeigt. Das Problem ist jedoch, dass beim Berühren eines Buchstabens das richtige Alphabetfeld angezeigt wird, um zu zeigen, welchen Buchstaben er in der in Bild (E) dargestellten großen Größe drückt. Wie kann ich das machen? Könnten Sie mir bitte helfen? Danke im Voraus!
