I want to update State list according to the country type in autocompletetextview. I have used the below code .It is working fine for the first time .I write country but once i edit the country name .It is not updating the state list(used notifyDataSetChanged but its not working).Please check the code .Thanks!
AutoCompleteTextView country_edit,state_edit;
for (int i = 1; i < global.getExcel().length; i++) {
String[] separated = global.getExcel()[i].split(",");
code = separated[0]; // this will contain "Fruit"
country = separated[1];
Log.e("length", code + "==" + country);
Log.e("sep", separated + "====" + global.getExcel()[i]);
countrylist.add(country);
codelist.add(code);
Log.e("countrylist", countrylist + "==");
}
//==============================================ArrayAdapter Country & state
final ArrayAdapter<String> country_adapter = new ArrayAdapter<String>
(this, R.layout.custom_autolistview_list, R.id.text1, countrylist);
country_edit.setThreshold(1);
country_edit.setAdapter(country_adapter);
final ArrayAdapter<String> state_adapter = new ArrayAdapter<String>
(this, R.layout.custom_autolistview_list, R.id.text1, State_array);
state_edit.setThreshold(1);
state_edit.setAdapter(state_adapter);
state_edit.setDropDownHeight(WRAP_CONTENT);
state_adapter.notifyDataSetChanged();
country_edit.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// Log.e("country", country_edit.getText().toString());
country_str = country_edit.getText().toString();
// Log.e("country", country_str);
int index = countrylist.indexOf(country_str);
Log.e("index", index + "");
String code_index = codelist.get(index);
Log.e("code", code_index);
State_list.clear();
State_array.clear();
for (int i = 0; i < global.getState().length; i++) {
if (global.getState()[i].contains("," + code_index + ",")) {
String statelist = global.getState()[i];
Log.e("statelist", statelist);
State_list.add(statelist);
Log.e("State", State_list + "");
state_name = "";
for (int j = 0; j < State_list.size(); j++) {
String[] statelist_array = State_list.get(j).split(",");
state_name = statelist_array[0];
String state_code = statelist_array[1];
Log.e("state_code", state_code);

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));
i have made ListView with three columns 'item','qty','rate' i get this entries from the user and i have made the listview work perfectly but i want to get all the values of the 'rate' column and add them for the net amount.
Here is my android code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
populateList();
adapter = new listviewAdapter(List.this, list);
lview.setAdapter(adapter);
}
private void populateList() {
HashMap temp = new HashMap();
list = new ArrayList<HashMap>();
item = etItem.getText().toString();
qty = etQty.getText().toString();
rate = etRate.getText().toString();
temp.put(FIRST_COLUMN, "1");
temp.put(SECOND_COLUMN, item);
temp.put(THIRD_COLUMN, qty);
temp.put(FOURTH_COLUMN, rate);
list.add(temp);
}
I tried out this method below but it only toast the first value.But i want to get all the values under the rate column and add them up for the net-amount.
public void get() {
StringBuilder sb = new StringBuilder();
for(int i=0; i<adapter.getCount(); i++) {
String a = ((TextView) findViewById(R.id.FourthText)).getText().toString();
adapter.getItem(i).toString();
sb.append(a);
sb.append("\n");
}
text = sb.toString();
Toast.makeText(getApplicationContext(), text, Toast.LENGTH_LONG).show();
}
I think this might help you.
private int GrandTotal(ListView list) {
int sum=0;
for (int i = 0; i < list.getCount(); i++) {
View v = list.getChildAt(i);
TextView rate = (TextView) v.findViewById(R.id.rate);
sum = sum + Integer.parseInt(rate.getText().toString() )
}
return sum;
}
:)
public void getTotalRate() {
int totalRate = 0;
for (int i = 0; i < list.size(); i++) {
HashMap temp = list.get(i);
/// here fourth column is rate
int rate = (int) temp.get(FOURTH_COLUMN);
totalRate = totalRate + rate;
}
Toast.makeText(getApplicationContext(), "total rate=" + totalRate, Toast.LENGTH_LONG).show();
}
I got ListView with simpleAdapter. If I click on some item in my List view it show me 2 diferent variables.
Some code:
// Listview Data
ArrayList<Map<String, Object>> data = new ArrayList<Map<String, Object>>(Invoice_numberArr.length);
Map<String, Object> m;
for(int i = 0; i<Invoice_numberArr.length; i++){
int str = Integer.parseInt(Invoice_numberArr[i]);
int str2 = Integer.parseInt(InvoiceNumberForDetails);
if(str == str2){
m = new HashMap<String, Object>();
m.put(ATT_INU, Invoice_numberArr[i]);
m.put(ATT_ANU, Article_numberArr[i]);
m.put(ATT_AMO, AmountArr[i]);
m.put(ATT_PRE, PriceArr[i]);
m.put(ATT_TPR, Total_priceArr[i]);
m.put(ATT_SDE, Sale_designationArr[i]);
data.add(m);
}
}
String[] from = {ATT_INU, ATT_ANU, ATT_AMO, ATT_PRE, ATT_TPR, ATT_SDE};
int[] till = {R.id.txtInvoice_number, R.id.txtArticle_number, R.id.txtAmount, R.id.txtPrice, R.id.txtTotalPrice, R.id.txtSale_designation};
//activities elements
invoices_list_details_view = (ListView)findViewById(R.id.invoices_list_details_view);
invoicesDetailsSAdapter = new SimpleAdapter(InvoicesDetails.this, data, R.layout.invoices_list_item_details_view, from , till);
invoices_list_details_view.setAdapter(invoicesDetailsSAdapter);
Utility Utility = new Utility();
Utility.setListViewHeightBasedOnChildren(invoices_list_details_view);
//if item clicked
invoices_list_details_view.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String positions = parent.getAdapter().getItem(position).toString();
//int positions = parent.getAdapter().;
parent.getAdapter();
int indexPos = -1; // if doesnt exist
for (int i = 0; i < Invoice_numberArr.length; i++) {
if (positions.contains("article_numbers="+Article_numberArr[i]+", "+"sale_designations="+Sale_designationArr[i]+", "+"amounts="+AmountArr[i]+", "+"invoice_numbers=" + Invoice_numberArr[i]+", "+"prices="+PriceArr[i]+", "+"total_prices="+Total_priceArr[i])) {
indexPos = i;
break;
} else if (positions.contains("prices="+PriceArr[i]+", "+"article_numbers="+Article_numberArr[i]+", "+"amounts="+AmountArr[i]+", "+"sale_designations="+Sale_designationArr[i]+", "+"invoice_numbers=" + Invoice_numberArr[i]+", "+"total_prices="+Total_priceArr[i])){
indexPos = i;
break;
}
}
//some int to transfer it to position class
int integerr = indexPos;
Intent invoices_details_position = new Intent(InvoicesDetails.this, InvoicesDetailsPosition.class);
invoices_details_position.putExtra("saleDesignationForPosition", Sale_designationArr[indexPos]);
invoices_details_position.putExtra("articleNumberForPosition", Article_numberArr[indexPos]);
invoices_details_position.putExtra("sequenceNumberForPosition", Sequence_numberArr[indexPos]);
invoices_details_position.putExtra("amountForPosition", AmountArr[indexPos]);
invoices_details_position.putExtra("warehouseForPosition", WarehouseArr[indexPos]);
invoices_details_position.putExtra("containerDescriptionForPosition", Container_descriptionArr[indexPos]);
invoices_details_position.putExtra("priceForPosition", PriceArr[indexPos]);
invoices_details_position.putExtra("discountForPosition", DiscountArr[indexPos]);
invoices_details_position.putExtra("totalPriceForPosition", Total_priceArr[indexPos]);
startActivity(invoices_details_position);
}
});
So if clicked on my item from ListView under android 4.3 till 5.0 varible
String positions = parent.getAdapter().getItem(position).toString();
shows me
string " {prices=10.8, article_numbers=0736, amounts=1, sale_designations=Pfirsichlikör, invoice_numbers=1, total_prices=10.8} "
And if I clicked under Android version 5.1 its shows me
string " {article_numbers=0736, sale_designations=Pfirsichlikör, amounts=1, invoice_numbers=1, prices=10.8, total_prices=10.8} "
Because that I need to check it twice with that
for (int i = 0; i < Invoice_numberArr.length; i++) {
if (positions.contains("article_numbers="+Article_numberArr[i]+", "+"sale_designations="+Sale_designationArr[i]+", "+"amounts="+AmountArr[i]+", "+"invoice_numbers=" + Invoice_numberArr[i]+", "+"prices="+PriceArr[i]+", "+"total_prices="+Total_priceArr[i])) {
indexPos = i;
break;
} else if (positions.contains("prices="+PriceArr[i]+", "+"article_numbers="+Article_numberArr[i]+", "+"amounts="+AmountArr[i]+", "+"sale_designations="+Sale_designationArr[i]+", "+"invoice_numbers=" + Invoice_numberArr[i]+", "+"total_prices="+Total_priceArr[i])){
indexPos = i;
break;
}
}
So my question now why does it changes depending on Android version ?
Thx for help.
Thank #Mike M. LinkedHashMap s instead HashMap s works for all Android
My listview is from a layout where its id is #android:id/list. It is part of the android.R.id.list. I used a SimpleCursorAdapter to setAdapter to listview. The listview contains checkboxes with contact names such as Emily Andrews, Susan John... I wanted to know the names of the contacts which were selected by the user. When using the code below, for some reason, it gives me random contact names in my unchecked list. For instance though I have Emily checked, and Matt Jones unchecked. It has both of them in the unchecked list. Also, no matter what i check and uncheck in the listview, it always gives me the first two contacts in my unchecked list and doesn't print anything for my checked list. Is there any way I can solve this?
public void blockCheckedItems(View view) {
// int cntChoice = lv.getCount();
checked = new ArrayList<String>();
unchecked = new ArrayList<String>();
int itempositions=adapter.getCount();
SparseBooleanArray sparseBooleanArray = lv.getCheckedItemPositions();
int countChoice = lv.getChildCount();
Log.d("" + countChoice, "CountChoice===============================");
Log.d("" + sparseBooleanArray,"sparseBooleanArray -------------------------");
for(int i = 0; i < countChoice; i++)
{
if(sparseBooleanArray.valueAt(i) == true)
{
Cursor cursor = (Cursor) lv.getItemAtPosition(i);
String name = cursor.getString(1);
checked.add(name);
}
else if(sparseBooleanArray.valueAt(i) == false)
{
Cursor cursor = (Cursor) lv.getItemAtPosition(i);
String name = cursor.getString(1);
unchecked.add(name);
}
}
for(int i = 0; i < checked.size(); i++){
Log.d("checked list&&&&&&&&&&&&&&&&&&&", "" + checked.get(i));
}
for(int i = 0; i < unchecked.size(); i++){
Log.d("in unchecked list&&&&&&&&&&&&&&&&&&&", "" + unchecked.get(i));
}
}
try this and let me know if i am wrong
public void blockCheckedItems(View view) {
ArrayList<String> checked = new ArrayList<String>();
ArrayList<String> unchecked = new ArrayList<String>();
SparseBooleanArray sparseBooleanArray = listView.getCheckedItemPositions();
for (int i = 0; i < listView.getCount(); i++) {
Cursor cursor = (Cursor) listView.getItemAtPosition(i);
String name = cursor.getString(1);
if (sparseBooleanArray.get(i)) {
checked.add(name);
} else {
unchecked.add(name);
}
}
for (int i = 0; i < checked.size(); i++) {
Log.d("checked list&&&&&&&&&&&&&&&&&&&", "" + checked.get(i));
}
for (int i = 0; i < unchecked.size(); i++) {
Log.d("in unchecked list&&&&&&&&&&&&&&&&&&&", "" + unchecked.get(i));
}
}
I have one array list, contains list of countries, next i selected particular student that is in string array. so how to find that selected string array of respective array list ids.
Code:
public class MainActivity extends Activity {
ArrayList<String> s = new ArrayList<String>();
private String log_email, log_pass, selectedcon = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
s.add("Nepal");
s.add("Korea");
s.add("Sri Lanka");
s.add("India");
s.add("Pakistan");
s.add("China");
s.add("Australia");
s.add("Bhutan");
String s1 = "Australia, Nepal, India, Korea";
String selectedHobbies[] = s1.split(",");
Log.d("TAG", "ddddd--" + "----"
+ selectedHobbies.length);
if (selectedHobbies.length != 0) {
for (int i = 0; i < s.size(); i++) {
for (int j = 0; i < selectedHobbies.length; j++) {
String t = selectedHobbies[j];
if (Arrays.asList(s.get(i)).contains(t)) {
selectedcon = selectedcon + i + ",";
Log.d("TAG", "Testing--" + i + "----"
+ selectedcon);
}
// int match=false;
}
}
}
Log.d("TAG", "Selected--ddddddddd---" + selectedcon);
}
}
I want of find ids of selected countries of array list.
ArrayList<String> s = new ArrayList<String>();
s.add("Nepal");
s.add("Korea");
s.add("Sri Lanka");
s.add("India");
s.add("Pakistan");
s.add("China");
s.add("Australia");
s.add("Bhutan");
String s1 = "Australia, Nepal, India, Korea";
String selectedHobbies[] = s1.split(",");
for (int i=0;i<s.size();i++) {
for (int j=0;j<selectedHobbies.length;j++) {
if (s.get(i).contains(selectedHobbies[j])) {
Log.d("xxx", "found");
Log.d("xxx", "s index " + i);
Log.d("xxx", "hobbies index " + j);
}
}
}
Corrected.
