In einer Listenansicht, in jeder Zeile, habe ich 10 Tasten. Wenn eine dieser Tasten gedrückt wird, sollte die Farbe der Tasten geändert werden (es entspricht dem Füllen der Leiste, je nachdem, wo Sie gedrückt haben). Hier ist, was ich bisher gemacht habe: Ich habe Referenzen von jeder Schaltfläche zu einer ArrayList namens Schaltflächen hinzugefügt. Ich habe auch eine ArrayList, die Farben Strings hat. Dies ist der Klick-Listener, der jeder Schaltfläche zugewiesen ist.Android: Ändern der Farbe aller Schaltflächen in der Listenansicht, wenn eine Taste gedrückt
Dies ist ein vollständiger Code-Formular meiner Adapter-Klasse der Listview.

Es sieht wie folgt aus: 
Also, wenn ich 3 drücken Sie die Taste, um alle Farben über 3, weiß werden müssen. Oder wenn ich Knopf 9 drücke, müssen alle Knöpfe davor seine Farben haben, und Knöpfe davor müssen weiß sein. Aber das passiert nicht, und es gibt keinen Fehler. Vielen Dank für Ihre Hilfe.
Können Sie es mit 10 einfachen Knopf innerhalb der horizontalen scrollview tun. Wenn deine Ansicht nur –
in deinem Code behoben ist, was ist das Problem? – sushildlh
ist da irgendein Fehler ?? – sushildlh
