How to change one adapter value from another adapter?

I have a little bit problem.In my activity there is two Adapter one is for color selection and another is for size selection. While i clicked one of the item of color then recently the available size adapter should be change but i got problem in size adapter. it changes only when i click the size item. I research and try to solve problem but it doesnt works for me.
Here is my code.
AddToCartActivity.java
public class AddToCartActivity extends BaseActivity{

At first both adapter will set data and after click color item the size adapter must be change but it only changes when i click any of the item. adapter.notifyDataSetChanged() doesnt work here for me.
Both Adapter set
When i click color item but doesnt change size adapter
when i click size item only change size adapter

Use Interface to bridge with two adapter and communicate with each other.

Your arrayList seems Null.
Update CustomBaseAdapter constructor as below:
public CustomBaseAdapter(Context context, List<RowItem> items) {
this.context = context;
this.rowItems = items;
arrayList = new ArrayList<String>();
for(int i = 0; i < rowItems.size(); i++)
{
RowItem rowItem = (RowItem) getItem(position);
arrayList.add(rowItem.getTitle());
}
}
In performFiltering do this:
...........
.......................
if (mOriginalValues == null) {
mOriginalValues.addAll(arrayList); // saves the original data in mOriginalValues
}
............

List View loses values on scroll,and get worg position on item click

I have the below ListView with a custom adapter. I received an ArrayAdapter from service, but something wrong is happening on scroll and the values are lost.
public class AccountStatementArrayAdapter extends ArrayAdapter<ListaExtratos> {
public AccountStatementArrayAdapter(Context context, int textViewResourceId, List<ListaExtratos> listaExtratos) {
super(context, textViewResourceId, listaExtratos);
this.listaExtratos = listaExtratos;
}
#Override
public int getItemViewType(int position) {
return listaExtratos.get(position).getData() == null ? SECTION : ACCOUNT_STATEMENT_ITEM;
}
#Override
public int getViewTypeCount() {
return 2;
}
#Override
public int getCount() {
return listaExtratos.size();
}
#Override
public ListaExtratos getItem(int position) {
return listaExtratos.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.list_item_account_statement, parent, false);
}
ListaExtratos p = getItem(position);
if (p != null && position != 0) {
TextView simpleDescriptionTextView = (TextView) v.findViewById(R.id.list_item_account_statement_simple_description_field);
TextView txtDataExtrato = (TextView) v.findViewById(R.id.txtDataExtrato);
TextView simpleValueTextView = (TextView) v.findViewById(R.id.list_item_account_statement_simple_value_field);
TextView completeDescriptionTextView = (TextView) v.findViewById(R.id.list_item_account_statement_complete_description_field);
TextView completeDateTextView = (TextView) v.findViewById(R.id.list_item_account_statement_complete_date_field);
TextView completeValueTextView = (TextView) v.findViewById(R.id.list_item_account_statement_complete_value_field);
TextView completeDocumentTextView = (TextView) v.findViewById(R.id.list_item_account_statement_complete_document_field);
TextView completeBalanceTextView = (TextView) v.findViewById(R.id.list_item_account_statement_complete_balance_field);
if(p.getHistorico() != null){
simpleDescriptionTextView.setText(p.getHistorico());
}
if(p.getValor() != null){
if ((p.getValor() != null) && (Double.parseDouble(p.getValor()) < 0)) {
simpleValueTextView.setTextColor(Color.RED);
completeValueTextView.setTextColor(Color.RED);
completeValueTextView.setText(StringUtil.getStringValueFromBigDecimal(new BigDecimal(p.getValor())));
simpleValueTextView.setText(StringUtil.getStringValueFromBigDecimal(new BigDecimal(p.getValor())));
} else {
simpleValueTextView.setTextColor(Color.BLACK);
completeValueTextView.setTextColor(Color.BLACK);
completeValueTextView.setText(StringUtil.getStringValueFromBigDecimal(new BigDecimal(p.getValor())));
simpleValueTextView.setText(StringUtil.getStringValueFromBigDecimal(new BigDecimal(p.getValor())));
}
}
if(p.getHistorico() != null)
completeDescriptionTextView.setText(p.getHistorico());
if(p.getData() != null)
completeDateTextView.setText(p.getData());
if(p.getDocto() != null)
completeDocumentTextView.setText(p.getDocto());
completeBalanceTextView.setVisibility(View.GONE);
if (!datas.contains(p.getData())) {
txtDataExtrato.setVisibility(View.VISIBLE);
txtDataExtrato.setText(DateUtil.getDataPorExtenso(DateUtil.dateFromString(p.getData(), "dd/MM/yyyy")));
datas += p.getData() + ";";
} else {
txtDataExtrato.setVisibility(View.GONE);
}
}
return v;
}
}

There are some bugs in your adapter code.
Remove check for position != 0
Add a else check as well where you set a empty text for each view.
For eg. :
Change this
if(p.getHistorico() != null){
simpleDescriptionTextView.setText(p.getHistorico());
}
to
if(p.getHistorico() != null){
simpleDescriptionTextView.setText(p.getHistorico());
}
else {
simpleDescriptionTextView.setText("");
}
These changes should solve your issue.

ListView with customAdapter not updated when notifyDataSetChanged is called?

I have a Listview with two adapters. They receive an Array with some data and when scrolled to bottom of the listview more data is loaded into the Array and here the listview should add the new data.
Question:
How can I make the listview reflect the new data and why isn't it updated when I call adAdapter.notifyDataSetChanged(); ?
Fragments inner class where I download data & update UI in onPostExecute:
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
numberofpagesshown = numberofpagesshown + 1;
if(numberofpagesshown == 1 ) {
list = (ListView) getActivity().findViewById(R.id.search_listview_movie);
adapter = new SearchListViewAdapter(getActivity(), mylist);
adAdapter = new BannerAdListView2(getActivity(), adapter);
// list.setAdapter(adapter); this works when adapter.notifyDataSetChanged(); also is in the else statement but here I don't use the BannerAdListView2 adapter which i want to?
list.setAdapter(adAdapter);
bar.setVisibility(View.GONE);
}
else {
// adapter.notifyDataSetChanged(); // Here the listview should get refresh with the new data
adAdapter.notifyDataSetChanged();
bar.setVisibility(View.GONE);
}
// Attach the listener to the AdapterView onCreate
list.setOnScrollListener(new EndlessScrollListener() {
#Override
public void onLoadMore(int page, int totalItemsCount) {
// Triggered only when new data needs to be appended to the list
// Append new items to AdapterView
if(pageNumberInt < totalPagesInt){
++incre;
new DownloadJSON().execute();
}
}
});
}
Here is my SearchListViewAdapter:
public class SearchListViewAdapter extends BaseAdapter{
Context context;
ArrayList<HashMap<String, String>> data;
HashMap<String, String> mylist = new HashMap<>();
static String url;
static String title;
public SearchListViewAdapter(Context a, ArrayList<HashMap<String, String>> d) {
context = a;
data = d;
}
public int getCount() {
return data.size();
}
public HashMap<String, String> getItem(int position) {
return data.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
// Avoid unneccessary calls to findViewById() on each row
final ViewHolder holder;
/*
* If convertView is not null, reuse it directly, no inflation
* Only inflate a new View when the convertView is null.
*/
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.search_list_item, parent, false);
holder = new ViewHolder();
holder.poster = (ImageView) convertView.findViewById(R.id.list_image);
holder.textForTitle = (TextView) convertView.findViewById(R.id.search_title);
holder.textForTitle.setTag(position);
convertView.setTag(holder);
}
else{
// Get the ViewHolder back to get fast access to the TextView
// and the ImageView.
holder = (ViewHolder) convertView.getTag();
holder.textForTitle.setTag(data.get(position));
}
mylist = data.get(position);
final String mediaType = mylist.get("media_type");
if (mediaType.equals("movie")) {
String posterPath = mylist.get("poster_path");
url = "http://image.tmdb.org/t/p/w185" + posterPath;
title = mylist.get("title");
} else if (mediaType.equals("tv")) {
String posterPath = mylist.get("poster_path");
url = "http://image.tmdb.org/t/p/w185" + posterPath;
title = mylist.get("original_name");
} else {
String posterPath = mylist.get("profile_path");
url = "http://image.tmdb.org/t/p/w185" + posterPath;
title = mylist.get("name");
}
// set image url correctly
// sizes for image 45, 92, 154, 185, 300, 500
// load image url into poster
Picasso.with(context).load(url).into(holder.poster);
// set title to textview
holder.textForTitle.setText(title);
return convertView;
}
class ViewHolder {
ImageView poster;
TextView textForTitle;
}
}
And my BannerAdListView2 adapter:
public class BannerAdListView2 extends BaseAdapter
{
Activity activity;
Context context;
BaseAdapter delegate;
int k = 7;
int baseItems;
int noAds;
// Constructor takes in a BaseAdapter
public BannerAdListView2(Activity activity, BaseAdapter delegate ) {
this.activity = activity;
this.delegate = delegate;
baseItems = delegate.getCount();
noAds = baseItems / k;
LayoutInflater mLayoutInflater = (LayoutInflater) this.activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
// Total count includes list items and ads.
return baseItems + noAds;
}
#Override
public Object getItem(int position) {
// Return null if an item is an ad. Otherwise return the delegate item.
if (isItemAnAd(position)) {
return null;
}
return delegate.getItem(getOffsetPosition(position));
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public int getViewTypeCount() {
return delegate.getViewTypeCount() + noAds;
}
#Override
public int getItemViewType(int position) {
if (isItemAnAd(position)) {
return delegate.getViewTypeCount();
} else {
return delegate.getItemViewType(getOffsetPosition(position));
}
}
#Override
public boolean areAllItemsEnabled() {
return false;
}
#Override
public boolean isEnabled(int position) {
return (!isItemAnAd(position)) && delegate.isEnabled(getOffsetPosition(position));
}
private boolean isItemAnAd(int position) {
if (position < k) return false;
// Calculate current offset caused by ads already embedded
if (position==k){
return true;
}
else {
return isItemAnAd(position-k);
}
}
// Get the position that is offset by the insertion of the ads
private int getOffsetPosition(int position) {
int currentNoAds = position / k;
return position - currentNoAds;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Display every n list items
if (isItemAnAd(position)) {
if (convertView instanceof AdView) {
// Don’t instantiate new AdView, reuse old one
return convertView;
} else {
// Create a new AdView
AdView adView = new AdView(activity);
adView.setAdSize(AdSize.BANNER);
String bannerId = "My unit id";
adView.setAdUnitId(bannerId);
// Disable focus for sub-views of the AdView to avoid problems with
// trackpad navigation of the list.
for (int i = 0; i < adView.getChildCount(); i++)
{
adView.getChildAt(i).setFocusable(false);
}
adView.setFocusable(false);
// Convert the default layout parameters so that they play nice with
// ListView.
float density = activity.getResources().getDisplayMetrics().density;
int height = Math.round(AdSize.BANNER.getHeight() * density);
AbsListView.LayoutParams params = new AbsListView.LayoutParams(
AbsListView.LayoutParams.MATCH_PARENT,
height);
adView.setLayoutParams(params);
AdRequest bannerIntermediateReq = new AdRequest.Builder()
.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
.addTestDevice("d9e108ab") //means that a test ad is shown on my phone
.build();
adView.loadAd(bannerIntermediateReq);
return adView;
}
} else {
// Offload displaying other items to the delegate
return delegate.getView(getOffsetPosition(position) ,
convertView, parent);
}
}
}
Edit:
Changed the constructor of BannerAdListView2
// Constructor takes in a BaseAdapter
public BannerAdListView2(Activity activity, final BaseAdapter delegate ) {
this.activity = activity;
this.delegate = delegate;
delegate.registerDataSetObserver(new DataSetObserver() {
public void onChanged() {
baseItems = delegate.getCount();
noAds = baseItems / k;
}
public void onInvalidated() {
notifyDataSetInvalidated();
}
});
baseItems = delegate.getCount();
noAds = baseItems / k;
LayoutInflater mLayoutInflater = (LayoutInflater) this.activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
And in fragment
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
numberofpagesshown = numberofpagesshown + 1;
if(numberofpagesshown == 1 ) {
list = (ListView) getActivity().findViewById(R.id.search_listview_movie);
adapter = new SearchListViewAdapter(getActivity(), mylist);
adAdapter = new BannerAdListView2(getActivity(), adapter);
list.setAdapter(adAdapter);
bar.setVisibility(View.GONE);
}
else {
adapter.notifyDataSetChanged();
bar.setVisibility(View.GONE);
}
}

Try this solution ... DecorerAdapter:

private final BaseAdapter mInnerAdapter;
private final int mRepeatAfterEvery;
private int mCount;
public DecorerAdapter(BaseAdapter innerAdapter, int repeatAfterEvery) {
mInnerAdapter = innerAdapter;
mRepeatAfterEvery = repeatAfterEvery;
mInnerAdapter.registerDataSetObserver(new DataSetObserver() {
#Override
public void onChanged() {
notifyDataSetChanged();
}
#Override
public void onInvalidated() {
notifyDataSetInvalidated();
}
});
setupAdapter();
}
#Override
public void notifyDataSetChanged() {
setupAdapter();
super.notifyDataSetChanged();
}
private void setupAdapter(){
mCount = mInnerAdapter.getCount();
mCount += (mCount + mRepeatAfterEvery - 2) / (mRepeatAfterEvery - 1);
DECORER_ITEM_TYPE = mInnerAdapter.getViewTypeCount();
}
#Override
public int getCount() {
return mCount;
}
#Override
public Object getItem(int position) {
if(position % mRepeatAfterEvery == 0)
return null;
return mInnerAdapter.getItem(calculateInnerPosition(position));

It repeats decorer view at every element passed to the constructor ...
all you need to do is implement getDecorerView in the similar way as getView in normal adapter

getview() is not calling on button click?

I am developing a Music Player. All songs are placed in the ListView with a ImageButton. This button is playing and pause the songs. So I am using getview(). But when I am clicking on the ImageButton, the songs are playing and pausing, but the image of play/pause is not changing. My main issue as I think, is that, when I am clicking on the ImageButton it is not calling the getview(). So please help me.
