拡張可能なカスタムアダプターにチェックボックスと子要素を持つカスタムアダプターがあり、親アイテムが選択されている場合-私の場合、注文が選択/チェックされている場合、注文はチェックボックスなしで新しいカスタムアダプターに渡されます。親、つまりオーダーを渡すことはできますが、子要素、つまりオーダーの子であるアイテムを渡すことができません。したがって、選択した注文の子要素を新しいアダプター ビューに渡す必要があります。
私のコード:
try {
System.out.println("READ/PARSING JSON");
serverStatus = jobj.getString("SERVER_STATUS");
System.out.println("serverStatusObj: "+serverStatus);
JSONArray serverResponseArray2=jobj.getJSONArray("SERVER_RESPONSE");
for (int m = 0; m < serverResponseArray2.length(); m++) {
String SERVER_RESPONSE = serverResponseArray2.getString(m);
JSONObject Open_Orders_obj = new JSONObject(SERVER_RESPONSE);
mMAX_ORDERS_TOBEPICKED = Open_Orders_obj.getInt("MAX_ORDERS_TOBEPICKED");
JSONArray ja = Open_Orders_obj.getJSONArray("ORDER_ITEM_DETAILS");
order_Item_Values.clear();
mOpenOrders = new ArrayList<OpenOrders>(ja.length());
for(int i=0; i<ja.length(); i++){
String ORDER_ITEM_DETAILS = ja.getString(i);
jobj1 = new JSONObject(ORDER_ITEM_DETAILS);
String ORDERNAME = jobj1.getString("ORDERNAME");
String ORDERID = jobj1.getString("ORDERID");
final OpenOrders parent = new OpenOrders();
parent.setOrderName(ORDERNAME+ " "+ i);
parent.setOrderID(ORDERID);
parent.setChecked((i % 2) == 0);
OpenOrders openOrderObj= new OpenOrders(ORDERID,ORDERNAME);
JSONArray Order_Items = jobj1.getJSONArray("ITEMS");
itemList =new ArrayList<String>();
parent.setChildren(new ArrayList<Child>());
for(int k=0; k<Order_Items.length(); k++){
String ITEMS = Order_Items.getString(k);
System.out.println(ITEMS);
ItemObj = new JSONObject(ITEMS);
String ITEMNUMBER = ItemObj.getString("ITEMNUMBER");
String ITEMNAME = ItemObj.getString("ITEMNAME");
itemList.add(ITEMNAME);//This adds item name's to the ArrayList named 'itemList'
openOrderObj.setItemID(ITEMNUMBER);
openOrderObj.setItemName(ITEMNAME);
System.out.println("item name"+ITEMNAME);
final Child child = new Child();
child.setName(ITEMNAME + i + "/" + k);
parent.getChildren().add(child);
}
mOpenOrders.add(parent);
}
}

ボタンがクリックされたとき、私がすることは次のとおりです。
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(mAdapter != null) {
int isSelectedOrderNumber=0;//This Variable will check with the parameter passed from server
mOpenOrdersSelected = new ArrayList<OpenOrders>();
StringBuffer sb = new StringBuffer();
Iterator<OpenOrders> it = mOpenOrders.iterator();
while(it.hasNext())
{
OpenOrders objOpenOrders = it.next();
//Do something with objOpenOrders
if (objOpenOrders.isChecked()) {
isSelectedOrderNumber++;
// mOpenOrdersSelected.add(new OpenOrders(objOpenOrders.getOrderID(),objOpenOrders.getOrderName()));
sb.append(objOpenOrders.getOrderID());
sb.append(",");
final OpenOrders parent = new OpenOrders(objOpenOrders.getOrderID(),objOpenOrders.getOrderName());
ArrayList<Child> mOpenOrderItems=objOpenOrders.getChildren();
Iterator<Child> i = mOpenOrderItems.iterator();
mOpenOrdersSelected.add(parent);
}
}
//Below Condition Will Check the selected Items With parameter passed "mMAX_ORDERS_TOBEPICKED"
if(isSelectedOrderNumber<1){
ShowErrorDialog("Please Select atleast One order");
return;
}
if(isSelectedOrderNumber>mMAX_ORDERS_TOBEPICKED){
ShowErrorDialog(" Select Maximum of "+mMAX_ORDERS_TOBEPICKED+ " Orders only to process");
return;
}
//Below code is to Call again the adapter and Displays the Order's which are checked/selected.
expListView = (ExpandableListView) findViewById(R.id.expandable_order_item_list);
ExpandableOrderSelectedListAdapter mOrderSelectedAdapter = new ExpandableOrderSelectedListAdapter(SelectLocationActivity.this,mOpenOrdersSelected);
expListView.setAdapter(mOrderSelectedAdapter);
expListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
//nothing to do , as Null Pointer exception Occurred ,to avoid that I just used this "setOnItemClickListener"
}
});
button.setVisibility(View.GONE);//Hide the Initial Button in the view
fullfilment_btn.setVisibility(View.VISIBLE);//Displays the confirm Button
fullfilment_btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
});
}
}
});
したがって、コードのこの部分では、子要素の反復中にエラーが発生します。
どんな助けでも素晴らしいでしょう
