ana hata

initialize veriler:: çizgide

ListViewRecent = (ListView) v.findViewById(R.id.ListView_Recent); 

     ListViewAdapter adapter = new ListViewAdapter(getActivity(),generateData()); 
ListViewRecent.setAdapter(adapter); 


private ArrayList<Model> generateData(){

Resources$NotFoundException: Resource ID #0xffffffff

modelsArrayList.get(position).getIcon() döndürülür -1 için altıgen ve Yapıcınızda ayarlanan değerdir O.

senin Fragment itibaren

, bu

models.add(new Model("Recent Updates"));

diyoruz Ve bu

// Are these meant to be one value?? 
private boolean isGroupHeader = false; 
private boolean groupHeader = false; 

public Model(String title) { 
    this(-1,title,null); // this line 
    isGroupHeader = true; 
} 
public Model(int icon, String title, String counter) { 
    super(); 
    this.icon = icon; // this gets a -1 
    this.title = title; 
    this.counter = counter; 
} 
public int getIcon() { 
    return icon; // this is causing the error 
} 
public boolean isGroupHeader() { 
    return groupHeader; // this is always false... 
}

girer Yani senin sorunun o boolean değeri her zaman false ve -1 çünkü ifadesi her zaman girilirse bu olmasıdır kaynak. Hatanız emilyPic tarihinde değil.

if(!modelsArrayList.get(position).isGroupHeader()){ 
    rowView = inflater.inflate(R.layout.row_listview, parent, false); 
    ImageView imgView = (ImageView) rowView.findViewById(R.id.iconlistview);

Yalnızca groupHeader boolean değerlerden birini kullanarak düzeltebilirim.

ama modele değişik resim eklemek istermiysem, bir çizim özelliğidir, çekilebilir değil. – Rost

Bunu tamir ettim. "R.drawable" olmalı ve her model için farklı bir simge göstereceğim, sadece yeni model yap (R.drawable.some_other_icon, ...) ' –

Bu gibi bir modeli başlatıyorum ArrayList models = new ArrayList (); models.add (yeni Model (R.drawable.emilypic, "Menü Öğesi 1", "1")); – Rost
