I call the method below to update my listview
ListView list = (ListView) listView.findViewById(R.id.plan_list);
itemsList = sortAndAddSections(getItems_search(name));
ListAdapter adapter = new ListAdapter(getActivity(), itemsList);
list.setAdapter(adapter);
but that code is associated with a value that changes and also this is the other code
private ArrayList<plan_model> getItems_search(String param_cusname) {
Cursor data = myDb.get_search_plan(pattern_email, param_name);
int i = 0;
while (data.moveToNext()) {
String date = data.getString(3);
String remarks = data.getString(4);
items.add(new plan_model(cusname, remarks);
}
return items;
}
and this is my sorter
private ArrayList sortAndAddSections(ArrayList<plan_model> itemList) {
Collections.sort(itemList);
plan_model sectionCell;
tempList.clear();
tmpHeaderPositions.clear();
String header = "";
int addedRow = 0;
int bgColor = R.color.alt_gray;
for (int i = 0; i < itemList.size(); i++) {
String remarks = itemList.get(i).getRemarks();
String date = itemList.get(i).getDate();
if (!(header.equals(itemList.get(i).getDate()))) {
sectionCell = new plan_model(remarks, date);
sectionCell.setToSectionHeader();
tmpHeaderPositions.add(i + addedRow);
addedRow++;
tempList.add(sectionCell);
header = itemList.get(i).getDate();
bgColor = R.color.alt_gray;
}
sectionCell = itemList.get(i);
sectionCell.setBgColor(bgColor);
tempList.add(sectionCell);
if (bgColor == R.color.alt_gray) bgColor = R.color.alt_white;
else bgColor = R.color.alt_gray;
}
tmpHeaderPositions.add(tempList.size());
for (int i = 0; i < tmpHeaderPositions.size() - 1; i++) {
sectionCell = tempList.get(tmpHeaderPositions.get(i));
sectionCell.setDate(sectionCell.getDate() + " (" +
(tmpHeaderPositions.get(i + 1) - tmpHeaderPositions.get(i) - 1) + ")");
}
return tempList;
}
my question is the value name changes but my listview is not how can I update my listview? because i need to update it based on search parameter
If your itemList is being updated properly, you don't need to create another instance of the adapter, just use notifyDataSetChanged():
private void createList() {
ListView list = (ListView) listView.findViewById(R.id.plan_list);
itemsList = sortAndAddSections(getItems_search(name));
adapter = new ListAdapter(getActivity(), itemsList);
list.setAdapter(adapter);
}
private void updateList() {
sortAndAddSections(getItems_search(name)); // Update itemList without re-assign its value, otherwise the adapter will loose reference
adapter.notifyDataSetChanged()
}
In getItems_search() add this line at the beginning:
items.clear();
Every time the value of name changes you have to do the following:
itemsList.clear();
itemsList = sortAndAddSections(getItems_search(name));
list.setAdapter(new ListAdapter(getActivity(), itemsList));
how to implement expandalbelistview with not any child
I am new in android I want to implement and expandalbelistview in which some groups have children and some have none.
Try This
It works for me
mExpandableListView = (ExpandableListView) findViewById(R.id.grouplist);
groupCollection = new LinkedHashMap<>();
List<String> newsCategories = new ArrayList<>();
List<String> nullcats = new ArrayList<>();
nullcats.add(null);
ArrayList<Categories> categories1 = new ArrayList<>();
//dataSource is my DBOpen helper class
categories1 = dataSource.findAllCategories();
if (categories1 != null) {
for (int i = 0; i < categories1.size(); i++) {
newsCategories.add(categories1.get(i).getCatagory_name_en());
}
} else {
newsCategories.add(null);
}
groupCollection.put(groupList.get(0), nullcats);
groupCollection.put(groupList.get(1), newsCategories);
expandableListAdapter = new ExpandableListAdapter(this, groupList, groupCollection);
mExpandableListView.setAdapter(expandableListAdapter);
I have the listview from the exel:
try {
Workbook wb = WorkbookFactory.create(getAssets().open("bos.xls"));
Sheet sheet = wb.getSheetAt(0);
for(int i = 0; i < sheet.getPhysicalNumberOfRows(); i++) {
Row row = sheet.getRow(i);
Cell form1 = row.getCell(0);
Cell form2 = row.getCell(1);
Cell form3 = row.getCell(2);
IrrList = new ArrayList<HashMap<String, Object>>();
HashMap<String, Object> hm;
hm = new HashMap<String, Object>();
hm.put(Form1, form1.getStringCellValue());
hm.put(Form2, form2.getStringCellValue());
hm.put(Form3, form3.getStringCellValue());
IrrList.add(hm);
SimpleAdapter adapter = new SimpleAdapter(this, IrrList,
R.layout.list_item, new String[] { Form1, Form2, Form3 },
new int[] { R.id.text1, R.id.text2, R.id.text3 });
listView.setAdapter(adapter);
listView.setTextFilterEnabled(true);
}
} catch(Exception ex) {
return;
}
When I use it I have the one value in my listview.
How can i correct it?
I tried to add this before "HashMap hm;":
for(int i1 = 0, l = IrrList.size(); i1 < l; i1++){
"I dont know what write here"
}
Try this..
Initilize the ArrayList before the for loop and set the listview adapter after the for loop
IrrList = new ArrayList<HashMap<String, Object>>();
for(int i = 0; i < sheet.getPhysicalNumberOfRows(); i++) {
Row row = sheet.getRow(i);
Cell form1 = row.getCell(0);
Cell form2 = row.getCell(1);
Cell form3 = row.getCell(2);
HashMap<String, Object> hm;
hm = new HashMap<String, Object>();
hm.put(Form1, form1.getStringCellValue());
hm.put(Form2, form2.getStringCellValue());
hm.put(Form3, form3.getStringCellValue());
IrrList.add(hm);
}
SimpleAdapter adapter = new SimpleAdapter(this, IrrList,
R.layout.list_item, new String[] { Form1, Form2, Form3 },
new int[] { R.id.text1, R.id.text2, R.id.text3 });
listView.setAdapter(adapter);
listView.setTextFilterEnabled(true);
The aim of the application is to have spinners left (home team) and on the right (Away team). I can successfully populate the home team spinners but when i try to populate the away team spinners i get the error:
06-25 18:02:36.052: W/System.err(17916): org.json.JSONException: Value at 0 is null.

According to json.org (http://www.json.org/javadoc/org/json/JSONArray.html#getJSONObject(int)):
getJSONObject throws JSONException if there is no value for the index
or if the value is not a JSONObject.
How your ateam array is being populated? Seems that you are adding null values inside it. Make sure that your ateam array is populated only with initialized JSONObject, maybe the JSONObject is null when you add it to ateam array so you must check if is null before adding it to ateam.
Below is Simple declaration in this a child and parent is being build with dynamic list value.With relevant code as createGroupList() and createChildList(). I am able to manipulate with TextView but one of field is my dynamic image from getting to JSON not is being load in WebView.
