TextViews、ImageViews、... を含むビューがありますが、ExpandableList を使用していくつかのデータを含めたいと考えています。この ExpandableList をビューに他のデータと共に含める方法がわかりません。
私の目的：
他のアクティビティにある ExpandableList を除くすべてのコンポーネントを 1 つのビューに持っています。
OfferDetailsActivity (これはビューを表示するアクティビティで、ここから ExpandableList を呼び出したい)
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;
