OnChildClick in ExpandableList funktioniert nicht

Question

Ich habe eine ExpandableListView erstellt, aber der OnClickListener funktioniert nicht. bereits andere Lösungen versucht, und alle folgen dem gleichen Muster von dem, was ich getan habe. Eine solche Lösungen gefunden, das war How to get onChildClick value from expandablelistview in android?

Meine Aktivität:

public class GroupRoutesActivity extends AppCompatActivity { 
public static ExpandableListView expandableListView; 
private static AdapterExpandableListGroups expandableListViewAdapter; 
ArrayList<Group> listProcess; 
Context ctx; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_group_routes); 

    ctx = GroupRoutesActivity.this; 
    expandableListView = (ExpandableListView) findViewById(R.id.expandable_group_routes); 
    expandableListView.setGroupIndicator(null); 
    expandableListView.setChildIndicator(null); 

    listProcess = new ArrayList<Group>(); 

    for(int i = 0; i<=2; i++){ 
     Group obj = new Group(); 
     obj.setId(String.valueOf(i)); 
     obj.setGroup(String.valueOf("Group "+i)); 
     obj.setCod("Cod Group "+String.valueOf(i)); 
     listProcess.add(obj); 
    } 

    HashMap<Group, List<Equipament>> allChildItems = returnGroupedChildItems(); 

    expandableListViewAdapter = 
      new AdapterExpandableListGroups(GroupRoutesActivity.this,listProcess, allChildItems); 


    expandableListView.setAdapter(expandableListViewAdapter); 

    expandableListView.setOnChildClickListener(new OnChildClickListener() { 
     @Override 
     public boolean onChildClick(ExpandableListView parent, View v, 
            int groupPosition, int childPosition, long id) { 
      Equipament e = ((Equipament)expandableListViewAdapter.getChild(groupPosition, childPosition)); 
      Toast.makeText(ctx, e.getCodEquipament(), Toast.LENGTH_LONG).show(); 
      return true; 
     } 
    }); 


} 

private HashMap<Group, List<Equipament>> returnGroupedChildItems() { 

    HashMap<Group, List<Equipament>> childContent = new HashMap<Group, List<Equipament>>(); 

    List<Equipament> equipaments = new ArrayList<Equipament>(); 
    for(int i=0; i<=2; i++){ 
     Equipament e = new Equipament(); 
     e.setId(String.valueOf(i)); 
     e.setType("Equipamemt "+i); 
     e.setCodEquipament("Cod Equip. "+String.valueOf(i)); 
     equipaments.add(e); 
     childContent.put(listProcess.get(i), equipaments); 
    } 
    return childContent; 
} 

AdapterExpandableList:

public class AdapterExpandableListGroups extends BaseExpandableListAdapter{ 
private Context context; 
private ArrayList<Group> list; 
private HashMap<Group, List<Equipament>> childDataSource; 

private static Activity act; 

public static int groupPosition = 0, childPosition = 0; 


public AdapterExpandableListGroups(Context context, ArrayList<Group> list, HashMap<Group, List<Equipament>> child) { 
    this.context = context; 
    this.list = list; 
    this.childDataSource = child; 
} 

@Override 
public int getGroupCount() { 
    return this.list.size(); 
} 

@Override 
public int getChildrenCount(int groupPosition) { 
    return this.childDataSource.get(this.list.get(groupPosition)).size(); 
} 

@Override 
public Object getGroup(int groupPosition) { 
    return list.get(groupPosition); 
} 

@Override 
public Object getChild(int groupPosition, int childPosition) { 
    return this.childDataSource.get(list.get(groupPosition)).get(childPosition); 
} 

@Override 
public long getGroupId(int groupPosition) { 
    return groupPosition; 
} 

@Override 
public long getChildId(int groupPosition, int childPosition) { 
    return childPosition; 
} 

@Override 
public boolean hasStableIds() { 
    return false; 
} 
static class ViewHolderParentGroup { 
    LinearLayout linearBackground; 
    TextView textCod; 
    TextView textDesc; 
} 

@Override 
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) { 
    LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    ViewHolderParentGroup viewHolder = null; 

    if (convertView == null) { 
     convertView = inflater.inflate(R.layout.layout_row_group_expandable, null); 
     viewHolder = new ViewHolderParentGroup(); 
     viewHolder.linearBackground = (LinearLayout) convertView.findViewById(R.id.linear_background_exapandable_group); 
     viewHolder.textCod = (TextView) convertView.findViewById(R.id.text_cod_group); 
     viewHolder.textDesc = (TextView) convertView.findViewById(R.id.text_desc_group); 
     convertView.setTag(viewHolder); 
    } else { 
     viewHolder = (ViewHolderParentGroup) convertView.getTag(); 
    } 

    viewHolder.textCod.setText(list.get(groupPosition).getCod()); 
    viewHolder.textDesc.setText(list.get(groupPosition).getGroup()); 
    return convertView; 
} 

@Override 
public View getChildView(int groupPosition, int childPosition, 
         boolean isLastChild, View convertView, ViewGroup parent) { 
    LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    ViewHolderParentGroup viewHolder = null; 

    if (convertView == null) { 
     convertView = inflater.inflate(R.layout.layout_row_equipament_expandable, null); 
     viewHolder = new ViewHolderParentGroup(); 
     viewHolder.linearBackground = (LinearLayout) convertView.findViewById(R.id.linear_background_exapandable_equipament); 
     viewHolder.textCod = (TextView) convertView.findViewById(R.id.text_cod_equipament); 
     viewHolder.textDesc = (TextView) convertView.findViewById(R.id.text_desc_equipament); 
     convertView.setTag(viewHolder); 
    } else { 
     viewHolder = (ViewHolderParentGroup) convertView.getTag(); 
    } 
    Equipament e = ((Equipament)getChild(groupPosition, childPosition)); 

    viewHolder.textCod.setText(e.getCodEquipament()); 
    viewHolder.textDesc.setText(e.getType()); 

    viewHolder.linearBackground.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      //Equipament e = ((Equipament)getChild(AdapterExpandableListGroups.groupPosition, AdapterExpandableListGroups.childPosition)); 
      //Toast toast = Toast.makeText(context, e.getCodEquipament(),Toast.LENGTH_SHORT); 
      //toast.show(); 
     } 
    }); 

    this.groupPosition = groupPosition; 
    this.childPosition = childPosition; 
    return convertView; 
} 

@Override 
public boolean isChildSelectable(int groupPosition, int childPosition) { 
    return true; 
} 

}

und mein ExpandableList Layout:

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="0dp" 
    android:layout_weight="0.9"> 
    <ExpandableListView 
     android:id="@+id/expandable_group_routes" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:childDivider="#000" 
     android:dividerHeight="0sp" 
     android:divider="#000"/> 
</LinearLayout>

Ihr Kind klickt auf die Listenerüberlappung mit dem ClickListener viewHolder.linearBackground.

Kommentieren Sie den untenstehenden Code, Sie können das Kind klicken.

viewHolder.linearBackground.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       //Equipament e = ((Equipament)getChild(AdapterExpandableListGroups.groupPosition, AdapterExpandableListGroups.childPosition)); 
       //Toast toast = Toast.makeText(context, e.getCodEquipament(),Toast.LENGTH_SHORT); 
       //toast.show(); 
      } 
     });
