Ich versuche, eine ListView mit 2 TextView zu erstellen. Ich bin nicht sehr gut in Java, deshalb folge ich normalerweise vielen Tutorials und kombiniere sie, um das zu erschaffen, was ich brauche.Mehrere TextView auf einer Listview
Aber ich habe versucht, ohne viel Erfolg 2 Führer zusammen zu kombinieren ...
Hier ist das Tutorial ich die zweite TextView zu folgen bin versucht, hinzuzufügen: https://www.youtube.com/watch?annotation_id=annotation_3104328239&feature=iv&src_vid=8K-6gdTlGEA&v=E6vE8fqQPTE
Aber das doesn‘ t mir wirklich helfen, da ich Schwierigkeiten habe zu verstehen, wie ich umsetzen kann, was er tut.
Bisher, was ich verstanden habe ist, dass ich so meine Artikel hinzufügen müssen:
countryList.add(new EntryItem("Électron","1/6"));
Dazu werde ich EntryItem und meine Klasse zu ändern, die BaseAdapter
Aber ich erstreckt war damit nicht erfolgreich.
Was ist der beste Weg, um meine zweite TextView hinzuzufügen?
