Listview not behaving well with Folding Cell Library

I have a problem using folding cell library from the RAMOTION
I have implemented everything but I am facing a problem with the list view
I have a list of planets and when user tap on let's say Jupiter the view gets unfolded and more information is visible to the user and when user tap on the same view which is seeing then the view gets folded
Problem
if the user scrolls down the list and then scroll back up and come back up to Jupiter the view remains unfolded and it is happening to all the view.
I appreciate if anyone helps me out

How avoid refresh checkbox while expand list in android

I'm making NLevel expandable list using listview. I've added checkbox only last level data in list view. I have stuck in below scenario.
If I check checkbox then when I expand listview means checkbox gets automatically unchecked.I don't want it to be like that. If I checked checkbox it should stay checked until I uncheck manually.
Please anyone help me!! It's been two days I stuck here.
Here goes my code:

Thanks in advance!!

i think you need to store the checkbox state in a boolean (is checked), and reflect that on the view, when getView() is called.
1- Add boolean checked to NLevelItem :
private boolean checked = false;
//add setter: setChecked(boolean)
//add getter isChecked()
2- Use that boolean in getView() (last one where checkbox is added)
#Override
public View getView(final NLevelItem item) {
// .......
final CheckBox checkBox = (CheckBox)view.findViewById(R.id.check);
checkBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//store checkbox state, note that NLevelItem item might need to be defined with 'final'
item.setChecked(checkBox.isChecked());
if(checkBox.isChecked()){
tempList.add((String) ((SomeObject)childs.getWrappedObject()).getName()+"+"+name);
}
else {
tempList.remove((String) ((SomeObject)childs.getWrappedObject()).getName()+"+"+name);
}
}//onClick()
}//setOnClickListener()
//update checkbox state from the corresponding NLevelItem
checkBox.setChecked(item.isChecked());
//.......
}//getView()
-EDIT:
to select 1 item, you need to iterate all items, set checked = false, but 1
i am not sure if you have to do it on:
List<NLevelItem> list;
or
List<NLevelListItem> filtered;
in the adapter class
private void selectOnly(int position){
for(int a=0;a<list.size();a++){
if(a == position){
list.get(a).setChecked(true);
continue;
}
list.get(a).setChecked(false);
}//for loop
notifyDataSetChanged(); // to update views (checkbox state)
}
Usage: selectOnly(15);

Use ViewHolder class to set and get Tag like this:
public class ListAdapter extends BaseAdapter {
private Context con;
private List<String> dataLt;
private static LayoutInflater inflater = null;
public ListAdapter(Context context, List<String> dataList){
con = context;
dataLt = dataList;
inflater = (LayoutInflater)con.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return dataLt.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
ViewHolder holder;
if(convertView==null){
/****** Inflate tabitem.xml file for each row ( Defined below ) *******/
vi = inflater.inflate(R.layout.list_item_search, null);
/****** View Holder Object to contain tabitem.xml file elements ******/
holder = new ViewHolder();
holder.textView = (TextView) vi.findViewById(R.id.textView);
/************ Set holder with LayoutInflater ************/
vi.setTag( holder );
}
else
holder=(ViewHolder)vi.getTag();
return vi;
}
public static class ViewHolder{
TextView textView;
}
}
Hope this may help.

Dynamic Spinners - if an item is selected from one spinner, hide it from other spinners - Android

How to hide an item from other spinners that is currently selected in one spinner?
I've tried removing the items via ArrayList of strings and ArrayAdapters, but I've noticed as soon as it's removed from the list, the selection is no longer referenced to the list item (because it does not exist anymore).
Now suppose, I have 4 spinner that are created dynamically and they all have the same ArrayList as their resource and now i would like to use this adapter to fetch the position of the selected item from 1 spinner and then hide it from 3 other spinners.
for (int i = 0; i < numberOfStops; i++) {
AddStopView stopView = new AddStopView(getActivity());
stopView.setCallback(BaseBookingFragment.this);
stopView.setPassengerNames(extraPassengerNames);
stopViews.add(stopView);
parent.addView(stopView, viewPosition);
}
In above code i am creating Stop Views dynamically and each Stop View having Passenger Name spinner. And these all spinners have the same ArrayList as their resource.
piece of code from AddStopView.java
public AddStopView(Context context) {
super(context);
initialize();
}
public void setCallback(StopViewCallback callback) {
this.callback = callback;
}
public void setPassengerNames(List<String> passengerNames) {
this.passengerNames = passengerNames;
passengerAdapter.setNames(passengerNames);
}
private void initialize() {
inflate(getContext(), R.layout.view_stop, this);
passengerAdapter = new ExtraPassengerAdapter(getContext());
passengerAdapter.setNames(passengerNames);
nameSpinner.setAdapter(passengerAdapter);
nameSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (view == null) {
return;
}
passengerName = (String) view.getTag();
if (position != 0)
callback.updatePassengerList(AddStopView.this, (position - 1));
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
code of call back of nameSpinner.setOnItemSelectedListener
#Override
public void updatePassengerList(AddStopView addStopView, int position) {
for (String passName : extraPassengerNames) {
if (addStopView.getPassengerName().equals(passName)) {
extraPassengerNames.remove(passName);
break;
}
}
for (AddStopView stopView : stopViews) {
if (!stopView.equals(addStopView))
stopView.setPassengerNames(extraPassengerNames);
}
}
code from ExtraPassengerAdapter.java
public class ExtraPassengerAdapter extends BaseAdapter {
private List<String> names = new ArrayList<>();
private Context context;
public ExtraPassengerAdapter(Context context) {
this.context = context;
names.add(get0Position());
}
public void setNames(List<String> names) {
this.names.clear();
this.names.add(get0Position());
this.names.addAll(names);
notifyDataSetChanged();
}
#Override
public int getCount() {
return names.size();
}
#Override
public String getItem(int position) {
return names.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView textView = (TextView) LayoutInflater.from(parent.getContext()).inflate(R.layout.adapter_stop, parent, false);
String name = getItem(position);
textView.setText(name);
textView.setTag(name);
return textView;
}
private String get0Position() {
return context.getString(R.string.passenger_name);
}
}

I think the right way to solve you problem is to create one list with all possible options and 4 lists with 4 adapters for each spinner. When something selected you update each list according to logic you described and call adapter.notifyDataSetChanged() for each adapter.

How to update listview in tab?

I have two tabs in my app and there are listviews in this tabs.
I set List data to each listvew.
I want to delete form list, and from listview when I click [x] image.
Item deleted from list In my code , but I dont know how to update listview,I use notifyDataSetChanged() in my customadapter, but not update.
Activity for first tab:
public static List<Product> mCartList;
mCartList = AllProducts.getCartList();
listViewCatalog = (ListView) findViewById(R.id.my_order_list);
mProductAdapter = new CustomListAdapter(MyOrders.this, mCartList, "", true);
listViewCatalog.setAdapter(mProductAdapter);
my Custom List Adapter:
public class CustomListAdapter extends BaseAdapter {
private LayoutInflater layoutInflater;
private Context mContext;
private List<Product> mProductList;
private String mType;
private boolean mShowQuantity;
public CustomListAdapter(Context context, List<Product> list, String type, boolean showQuantity) {
layoutInflater = LayoutInflater.from(context);
mContext = context;
mProductList = list;
mShowQuantity = showQuantity;
mType = type;
}
#Override
public int getCount() {
return mProductList.size();
}
#Override
public Object getItem(int position) {
return mProductList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder item;
final int finalMPosition = position;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.list_row, null);
item = new ViewHolder();
item.imageView = (ImageView) convertView.findViewById(R.id.product_image);
item.name = (TextView) convertView.findViewById(R.id.name);
item.pid = (TextView) convertView.findViewById(R.id.pid);
item.price = (TextView) convertView.findViewById(R.id.price);
item.description = (TextView) convertView.findViewById(R.id.description);
item.removeProduct = (ImageView) convertView.findViewById(R.id.removeProduct);
item.addToCart = (TextView) convertView.findViewById(R.id.addtocard);
item.productQuantity = (TextView) convertView.findViewById(R.id.textViewQuantity);
convertView.setTag(item);
} else {
item = (ViewHolder) convertView.getTag();
}
final Product curProduct = mProductList.get(position);
item.imageView.setImageDrawable(curProduct.imageView);
item.name.setText(curProduct.name);
item.pid.setText(curProduct.pid);
int length = curProduct.description.length();
int start = 0, end = length;
if (length >= 40) {
start = 0;
end = 40;
}
String s = curProduct.description.substring(start, end);
item.description.setText(s + "...");
item.price.setText(curProduct.price + mContext.getString(R.string.currency));
if (mShowQuantity) {
item.addToCart.setVisibility(View.GONE);
// item.productQuantity.setText("Quantity: " + AllProducts.getProductQuantity(curProduct));
item.productQuantity.setVisibility(View.GONE);
} else {
item.productQuantity.setVisibility(View.GONE);
item.removeProduct.setVisibility(View.GONE);
}
item.removeProduct.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
AlertDialog.Builder ab = new AlertDialog.Builder(mContext);
ab.setTitle("Delete ");
ab.setMessage("This product will be deleted from list.").setPositiveButton("Delete", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
curProduct.selected = false;
AllProducts.removeProduct(curProduct);
notifyDataSetChanged();
notifyDataSetInvalidated();
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
ab.create().show();
}
});
item.addToCart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent productDetailsIntent = new Intent(mContext, ProductDetail.class);
productDetailsIntent.putExtra(AllProducts.PRODUCT_INDEX, finalMPosition);
productDetailsIntent.putExtra("type", mType);
mContext.startActivity(productDetailsIntent);
}
});
return convertView;
}
public class ViewHolder {
TextView pid;
TextView addToCart;
TextView name;
TextView price;
TextView description;
ImageView imageView;
ImageView removeProduct;
TextView productQuantity;
}
}

You can introduce notifyDataSetChanged() in the list view or you can reset the setAdapter() which the new list values , but later one will be costly

You have 2 different List, try doing this:
Create a constructor without passing a List i mean:
CustomListAdapter(MyOrders.this, "", true);
Then in the CustomListAdapter create an List Local variable and instatiate it in the constructor:
private List<Product> mProductList;
public CustomListAdapter(Context context, String type, boolean showQuantity) {
layoutInflater = LayoutInflater.from(context);
mContext = context;
mProductList = new ArrayList<Product>();
mShowQuantity = showQuantity;
mType = type;
}
then create an Add or Delete method in the CustomListAdapter:
public void AddItem(Product product){
if(null != product){
mProductList.add(product);
}
}
Then an updateMethod too:
public void update(){
mProductList.notifyDataSetChanged();
}

if notifyDatasetChanged is not working try to use this
yourlist.invalidateviews();

You need to remove that particular item from arraylist by calling
AllProducts.remove(position);
notifyDatasetChanged();

write this methode in your adapter and use it to remove perticular Item from adapter.
public void remove(int position){
mProductList.remove(position);
notifyDatasetChanged();
}

I resolved my problem.
public static void setTab(int i){
if(i==0){
mTabHost.setCurrentTab(i+1);
mTabHost.setCurrentTab(i);
}
else{
mTabHost.setCurrentTab(i-1);
mTabHost.setCurrentTab(i);
}
}
and
#Override
public void onClick(DialogInterface dialog, int which) {
curProduct.selected = false;
AllProducts.removeProduct(curProduct);
MyTabActivity.setTab(0);
}
and for second listview:
MyTabActivity.setTab(1);

The only reason it is not working for you now, is because you have two different lists. You are removing from wrong list.
So first of all, do not delete from your list. Write a method in your adapter where you remove it from list you have stored in that Adapter, and then call notifyDatasetChanged in that method.

Working with tabs in android 2.x, I found a bug in the emulator: The tabs are not correctly refreshed or removed. Alternatives is to use support library v7 which as support for action bar tabs.

Use following code to update ListView.
In order to update ListView you must have to call notifyDataSetChanged(); menthod on Adapter. See Below code.
What you did.
notifyDataSetChanged();
notifyDataSetInvalidated();
What you have to do is,
yourAdapter.notifyDataSetChanged();
Or you may use following code to refresh your list.
private List<Object> mCarlistitem= new ArrayList<Object>();
public void refreshlist()
{
mCarlistitem.clear();
for(int i=0; i< mCartList.size(); i++)
{
Object object = new Object();
mCarlistitem.add(object);
}
mProductAdapter = new CustomListAdapter(MyOrders.this, mCartList, "",true);
listViewCatalog.setAdapter(mProductAdapter);
}

update listview from an Array adapter

I'm trying to refresh the list view when I click on a single item of the list view.
For example I'm trying to do something like this:
public class RssItemsAdapter extends ArrayAdapter<Item> {
private TextView txtTitle;
private ImageView imgFavourite;
private int resourceId;
private Context context;
private List<Item> items = new ArrayList<Item>();
public RssItemsAdapter(Context context, int resourceId, List<Item> items)
{
super(context, resourceId, items);
this.context = context;
this.items = items;
this.resourceId = resourceId;
}
#Override
public int getCount() {
return items.size();
}
#Override
public Item getItem(int index) {
return items.get(index);
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
Item item = getItem(position);
if (row == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(resourceId, parent, false);
}
txtTitle = (TextView) row.findViewById(R.id.title);
txtTitle.setText(item.getTitle());
imgFavourite = (ImageView) row.findViewById(R.id.favourite);
imgFavourite.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (item.isFavourite() == true) {
imgFavourite.setBackgroundResource(android.R.drawable.btn_star_big_off);
}
else {
imgFavourite.setBackgroundResource(android.R.drawable.btn_star_big_on);
}
}
});
// add a "star" icon on favourite items
if (item.isFavourite() == true)
imgFavourite.setBackgroundResource(android.R.drawable.btn_star_big_on);
else
imgFavourite.setBackgroundResource(android.R.drawable.btn_star_big_off);
return row;
}
Every time I click on the imgFavourite icon it should change. Where is the problem?

It doesn't look like you are ever changing the value of item.isFavourite(). Assuming you want to toggle when that item is clicked...
imgFavourite.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Toggle the current state
item.setIsFavourite(!item.isFavourite());
if (item.isFavourite() == true) {
imgFavourite.setBackgroundResource(android.R.drawable.btn_star_big_off);
}
else {
imgFavourite.setBackgroundResource(android.R.drawable.btn_star_big_on);
}
}
});
Also, you should be doing this kind of work in the ListView's onItemClickListsner. As is, this will create a new onClickListener each time a new row is brought into view. Beyond that, check into the "view holder pattern".
