Utilizzare un'immagine nella ExpandableList

[Carontes]

Risolto un problema se ne presenta un altro Ho una ExpandableList e vorrei inserire un'immagine diversa per ogni child solo che non ci riesco. Forse perchè devo impostare un file xml specifico per il child e uno per il group?

<?xml version="1.0" encoding="utf-8"?><br /> <LinearLayout xmlns:android="http://schemas.android.com/<span class="forTooltip">apk</span>/res/android"<br /> android:orientation="vertical"<br /> android:layout_width="fill_parent"<br /> android:layout_height="fill_parent"<br /> android:background="@drawable/secondapagina" <br /> android:scrollbars="none"><br /> <ExpandableListView android:id="@+id/expandableListView1"<br /> android:layout_width="fill_parent"<br /> android:background="@drawable/secondapagina" <br /> android:layout_height="fill_parent" <br /> android:divider="@drawable/separatore" <br /> android:paddingLeft="25dip" <br /> android:paddingRight="4dip" <br /> android:scrollbars="none"/><br /> </LinearLayout>

Un'ultima cosa, io vorrei far scrollare l'immagine di background solo che questa sta ferma sullo sfondo mentre scrolla solo la ExpandableList, è possibile farlo oppure devo usare qualche altra cosa? Grazie.

[Jordano]

puoi, basta fare un layout con l'immagine per il child della ExpandableListView e poi mappare il tutto in modo corretto.



per lo sfondo potresti provare a impostare l'immagine come background del LinearLayout che contiene la ExpandableListView, e impostare il background della ExpandableListView come semitrasparente o trasparente.

[Carontes]

Le ExpandableList non vengono molto menzionate, sia nei libri cartacei per Android sia nelle guide che si trovano su internet, non ne so molto su questo argomento. Leggendo quel poco avevo intuito che dovevo fare un layout per il child e quindi di conseguenza tutto quel codice java non serve a nulla, andrebbe riscritto vero?

[Jordano]

qua puoi trovare forse parzialmente ispirazione per come fare a mettere nei child un layout con un immagine che presumo rappresenti il cocktail e il nome del cocktail.

[android-developers] Re: Customize layout of ExpandableListView

non ho letto nel dettaglio perchè ora non ho tempo, ma ho visto che estende l'adapter e ho visto che nel layout del child c'è una ImageView, quindi sicuramente qualche spunto puoi prenderlo.

Questo è il file di logcat. Mi da errore appena avvio l'app: Spiacenti, interruzione imprevista dell'applicazione sed (processoit.gogle.com).Riprova.

[Jordano]

leggi bene, hai un errore che esci dagli indice del vettore

[Carontes]

Si alla fine ho trovato l'errore, era solo un numero sbagliato. Adesso però non riesco a mettere un'immagine diversa per ogni child. Con il codice che ho posso solo settare la stessa immagine per tutti i child oppure dirgli di mettere una certa immagine per tutti i child presenti nella posizione x di un gruppo ed il resto avranno un'altra immagine. Ti ringrazio infinitamente se riesci a risolvermi questo problema altrimenti ti ringrazio lo stesso per l'aiuto che mi hai dato finora
