我有一個視圖與TextViews,ImageViews,但我想包括使用ExpandableList一些數據。我不知道如何將這個ExpandableList與其他數據一起包含在我的View中。如何在視圖中包含ExpandableListActivity

我objetive:

MyView

我已經除了ExpandableList在一個視圖中的所有組件,我有其他活動:

OfferDetailsActivity(這是活動昭示着查看並從這裏我想打電話到ExpandableList)

public class OfferDetailsActivity extends Activity{ 

final public static String OFERTA = "oferta"; 
private Oferta oferta = null; 

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState);  
    setContentView(R.layout.offer_details);    

    oferta = (Oferta)getIntent().getExtras().getParcelable(OFERTA); 

    View view = new View(this.getBaseContext()); 

    LayoutInflater linflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    view = linflater.inflate(R.layout.offer_details, null); 

    // poblamos la lista de elementos   
    TextView precio = (TextView)view.findViewById(R.id.precio_offer_details); 
    precio.setText(oferta.getPrecio()); 

    ImageView imagen = (ImageView) view.findViewById(R.id.imagen_offer_details); 
    imagen.setImageBitmap(new GetImages().downloadFile(oferta.getImagen())); 

    TextView cabecera = (TextView)view.findViewById(R.id.cabecera_offer_details); 
    cabecera.setText(oferta.getCabecera()); 

    TextView descripcion = (TextView)view.findViewById(R.id.descripcion_offer_details); 
    descripcion.setText(oferta.getDescripcion());             

    setContentView(view); 

}           

}

ExpandableList

public class ExpandableList extends ExpandableListActivity { 

@SuppressWarnings("unchecked") 
public void onCreate(Bundle savedInstanceState) { 
    try{ 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.offer_details); 

    SimpleExpandableListAdapter expListAdapter = 
     new SimpleExpandableListAdapter(
       this, 
       createGroupList(),    // Creating group List. 
       R.layout.group_row,    // Group item layout XML.   
       new String[] { "Group Item" }, // the key of group item. 
       new int[] { R.id.row_name }, // ID of each group item.-Data under the key goes into this TextView.     
       createChildList(),    // childData describes second-level entries. 
       R.layout.child_row,    // Layout for sub-level entries(second level). 
       new String[] {"Sub Item"},  // Keys in childData maps to display. 
       new int[] { R.id.grp_child}  // Data under the keys above go into these TextViews. 
      ); 
     setListAdapter(expListAdapter);  // setting the adapter in the list. 

    }catch(Exception e){ 
     System.out.println("Errrr +++ " + e.getMessage()); 
    } 
} 

/* Creating the Hashmap for the row */ 
@SuppressWarnings("unchecked") 
private List createGroupList() { 
     ArrayList result = new ArrayList(); 
     for(int i = 0 ; i < 15 ; ++i) { // 15 groups........ 
     HashMap m = new HashMap(); 
     m.put("Group Item","Group Item " + i); // the key and it's value. 
     result.add(m); 
     } 
     return (List)result; 
} 

/* creatin the HashMap for the children */ 
@SuppressWarnings("unchecked") 
private List createChildList() { 

    ArrayList result = new ArrayList(); 
    for(int i = 0 ; i < 15 ; ++i) { // this -15 is the number of groups(Here it's fifteen) 
     /* each group need each HashMap-Here for each group we have 3 subgroups */ 
     ArrayList secList = new ArrayList(); 
     for(int n = 0 ; n < 3 ; n++) { 
     HashMap child = new HashMap(); 
     child.put("Sub Item", "Sub Item " + n);   
     secList.add(child); 
     } 
    result.add(secList); 
    }   
    return result; 
} 
public void onContentChanged () { 
    System.out.println("onContentChanged"); 
    super.onContentChanged();   
} 
/* This function is called on each child click */ 
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition,int childPosition,long id) { 
    System.out.println("Inside onChildClick at groupPosition = " + groupPosition +" Child clicked at position " + childPosition); 
    return true; 
} 

/* This function is called on expansion of the group */ 
public void onGroupExpand (int groupPosition) { 
    try{ 
     System.out.println("Group exapanding Listener => groupPosition = " + groupPosition); 
    }catch(Exception e){ 
     System.out.println(" groupPosition Errrr +++ " + e.getMessage()); 
    } 
} 

}

移動從擴展列表活動代碼到其他qctivity並把必要位的其他活動XML文件中,你應該罰款...有你有一些問題阻止你這樣做?

也許繼承問題...活動的一個活動擴展和ExpandableListActivity的其他擴展。我會盡力去做你說的。 – JoseAntonio1984

您可能需要做的唯一更改是查找可展開列表視圖(findViewById),因爲Activity不會假定該標識。你調用的設置適配器的方法是不同的(如果我正確記得,setAdapter vs setListAdapter)。 – Barak

如果將代碼從ExpandableList.class移動到OfferDetailsActivity.class出現編譯錯誤,例如,如果您從ExpandableListActivity擴展,則只有「createGroupList()」和「createChildList()」方法可用。爲了解決這個問題,我決定保留2個類並在OfferDetailsActivity.class中寫這行以在setContentView(view)之前調用其他類。不能正常工作:ExpandableListView oExpandableListView = new ExpandableListView(this.getBaseContext()); \t \t \t oExpandableListView.setAdapter(new ExpandableList()。getExpandableListAdapter()); – JoseAntonio1984
