wie machen gesamte Zeile der Listen-Ansicht anklickbar?

Ich versuche, mehrere Kontakt-picker für meine Anwendung. Ich bin mit einem benutzerdefinierten layout-mit checkbox zum auswählen mehrerer Kontaktieren. Das problem, das ich konfrontiert ist, dass, um zum auswählen eines bestimmten Kontakt, den ich klicken muss genau auf die checkbox, wenn ich auf den anderen Teil der Zeile die checkbox nicht angekreuzt. Wie kann ich sicherstellen, dass dort, wo der Benutzer klickt in die gesamte Reihe (das Kontrollkästchen wird mit einem Häkchen gekennzeichnet.
