父列表适配器：

其中父列表负载

儿童适配器：

public View getView(int position, View convertView, ViewGroup parent) { 

    ViewHolder holder; 
    String item = null, qty = null; 
    if (convertView == null) { 
     holder = new ViewHolder(); 
     convertView = inflator.inflate(R.layout.itembumpingadapter, null); 
     holder.qty = (TextView) convertView.findViewById(R.id.qty); 
     holder.name = (TextView) convertView.findViewById(R.id.item); 
     holder.childText = (TextView) convertView 
       .findViewById(R.id.childitem); 
     holder.qtyChild = (TextView) convertView 
       .findViewById(R.id.qtychild); 
     holder.checkbox = (CheckBox) convertView.findViewById(R.id.chckbox1); 
     convertView.setTag(holder); 


    } else { 

     holder = (ViewHolder) convertView.getTag(); 
    } 
    parentobjid = newListitems.get(position).getParentobjectid(); 
    if (!parentobjid.isEmpty()) { 
     holder.name.setText(" " + newListitems.get(position).getItemnNameDisplay()); 
     holder.name.setTextColor(Color.parseColor("#CC0000")); 
     holder.qty.setText("  " + String.valueOf(newListitems.get(position) 
       .getQuantityDisplay())); 
     holder.qty.setTextColor(Color.parseColor("#CC0000")); 
    } else { 

     holder.name.setText(newListitems.get(position).getItemnNameDisplay()); 
     holder.qty.setText(String.valueOf(newListitems.get(position) 
       .getQuantityDisplay())); 
     holder.name.setTextColor(Color.parseColor("#FFFFFF")); 
     holder.qty.setTextColor(Color.parseColor("#FFFFFF")); 
     holder.checkbox.setChecked(false); 

     holder.checkbox.setTag(position); 

     holder.checkbox.setOnClickListener(new OnClickListener() { 


      @Override 
      public void onClick(View v) { 

       int pos = (Integer) v.getTag(); 
       newListitems.get(pos).setChecked(!newListitems.get(pos).isChecked()); 

      } 

     }); 
     if (newListitems.get(position).isChecked()) { 
      holder.name.setEnabled(true); 
      holder.name.setBackgroundColor(Color.parseColor("#DCDBDB")); 


     } else { 
      holder.name.setEnabled(false); 
     } 


    } 
    return convertView; 
}

您应该使用ExpandableListView，如果你有一个孩子列表父列表。如果您不熟悉它，请检查this link以了解更多信息。

点击时有由ExpandableListView它提供了一个OnChildClickListener提供给你，孩子的地位和家长的位置：

// Listview on child click listener 
expListView.setOnChildClickListener(new OnChildClickListener() { 

     @Override 
     public boolean onChildClick(ExpandableListView parent, View v, 
       int groupPosition, int childPosition, long id) { 
      // TODO Auto-generated method stub 
      Toast.makeText(
        getApplicationContext(), 
        listDataHeader.get(groupPosition) 
          + " : " 
          + listDataChild.get(
            listDataHeader.get(groupPosition)).get(
            childPosition), Toast.LENGTH_SHORT) 
        .show(); 
      return false; 
     } 
    }); 

希望这有助于！
