Android Listview does not refresh/redraw

Problem - I have list of in app purchases loaded from app store in a Listview.
When user purchases (taps on a button in listview) the item is purchased and the button should be now hidden and the list item purchased should show an image of tick.
What I have tried -
Refresh the listview after item is purchased by calling notifyDataSetChanged
Set the visibility of the button and image using View.GONE and View.VISIBLE
None of the above seems to work.
I am using this in app billing library
public class ListViewAdapter extends ArrayAdapter<Product> {
private ArrayList<Product> iapProducts= new ArrayList<>();

holder = new ViewHolder();
holder.name = (TextView) vi.findViewById(R.id.languageName);

holder.purchaseButton = (Button) vi.findViewById(R.id.iapProductPurchaseBtn);

} else {

}

}
//add all the products to adapter
adapter.addAll(productsToPurchase);
}
}

this.imageTick = (ImageView) imageTick;
this.buttonPurchase = (Button) button;
bp.purchase(this,productId);
}
#Override
public void onProductPurchased(String productId, TransactionDetails details) {
//hide button show image
this.imageTick.setVisibility(View.VISIBLE);
this.buttonPurchase.setVisibility(View.GONE);
adapter.setIapProducts(new ArrayList<>(productsToPurchase));
adapter.notifyDataSetChanged();
}
}

(Moved comment into a post)
After a user purchases something, is that Product within productsToPurchase updated? The adapter looks okie so maybe the list you're using isn't being updated after a purchase.
I'm assuming you need to flip the isPurchased flag of the Product in onProductPurchased() using the provided productId.

How to wire up a delete button to delete one item on a listview?

I know there are lots of threads with more or less same topic but none of them covers my situation:
I am trying to get my delete button to delete one row on the list view and the delete button appear in each row I got this part to work but I can't get it to work in my Main Activity. The code keeps breaking every time I put this part in my code:
ImageButton removeButton = (ImageButton) findViewById(R.id.btnDel);
removeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
onRemoveButtonClick();
}
private void onRemoveButtonClick() {
ToDoItem item = (ToDoItem) v.getTag();
notifyDataSetChanged();
}
my MainActivity works fine without this bit of code. I don't know if it is the code or if it is where I am placing it in my MainActivity if someone would please tell that would much appreciated.

1.) Add a button to your to_do_item_layout first
2.) Now add this code to add a button to each item
Button btn = (Button) convertView.findViewById(R.id.my_btn);
3.) Add a listener to it
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
items.remove(items.get(position));
}
});

i have tried all thing to send all the data of list view to another activty please suggest me how can i do it ??

Make the list static and u can then access it in any activity. Make sure u initialise the list

milk class extends serializable firstly
then u do
make object of milk class in mainactivity class
Milk milk=new Milk(this);
Intent i=new Intent(getApplicationContext(),Update.class);
i.putExtra("emnumber",(Serializable)milk);
startActivity(i);
then u can pick the value in update class
if(getIntent().getSerializableExtra("emnumber")!=null) {
con = (ArrayList<Contact>) getIntent().getSerializableExtra("emnumber");
email_mobile = contactList.get(0).nsme;
pass__word = contactList.get(0).amount;

you can implement as:
public class Milk implements Parcelable{
......
}
Send arraylist as:
intent.putExtra("files", "your arraylist");
obtain arraylist as:
Intent inIntent = getIntent();
list=inIntent.getParcelableArrayListExtra("files");

Try this. May be it help.
Send arraylist to activity through extras.
intent.putStringArrayListExtra("ARRAY_LIST", arrayList);
Retrieve arraylist in activity.
arrayList= i.getStringArrayListExtra("ARRAY_LIST");
If u have to send arraylist other than string then.
intent.putParcelableArrayListExtra("ARRAY_LIST", (ArrayList<Milk>) milkArrayList);
Milk class must be parcellable

How to set Text in Textview when Click on selected item in Listview?

I am using Listview with ViewHolder, and setText in Textview then display error. How to setText in Textview in Listview? Whenever I click on Like Button then I get the total count for Like but I am not able to setText on TextView for every item. whenever click on selected item then Its TextView Increment by 1 Its Successfully. get strCount is Successfully but how to setText for Selected TextView when Click on Selected Image and My code is,
My Screenshot is which is Listview and set Multiple Items in Listview Like,

Thanks in advance.

In onClick() function you have to get instance of textview and pass it to AsyncTask
// if text and img have same parent the you can find textview like this is
TextView tv =(TextView)v.getParent().findViewById(R.id.txt);
// if not then apply call getParent() function multiple time as per your layout
new sendData(tv).execute();
//Create constructor in sendData
public class sendData extends AsyncTask {
private TextView tv;
public sendData(TextView v){
tv=v;
}
...
protected void onPostExecute(Void result) {
super.onPostExecute(result);
urlCount = "http://example.com/getalldata.php?id="
+ strId;
new getCountData(tv).execute();
};
}
private class getCountData extends AsyncTask {
private TextView v;
public sendData(TextView v){
tv=v;
}
....
// in onPostExecute use
tv.setText(String.valueOf(strCount));
}
Edit: you can get correct position by tag position to view and get it inside onClick
// add this line before return
viewHolder.img.setTag(position);
// get position inside onClick()
int position =(Integer)v.getTag();

Cannot see listview in fragment

I am currently modifying an android app that I need to add a listview to an existing fragment. As I am new to android, I am just imitating the code from the apps. I created a new arrayadapter, a new class of data and made some modifies to the existing fragment class. The problem is I cannot see my list in the app. Below are my codes.
Adapter
public class RecordArrayAdapter extends ArrayAdapter<CheckInRecord.CheckInRec> {
private int resourceId;
private Context context;
private List<CheckInRecord.CheckInRec> checkInRec;
public RecordArrayAdapter(Context context, int resourceId, List<CheckInRecord.CheckInRec> checkInRec)
{
super(context, resourceId, checkInRec);
this.resourceId = resourceId;
this.context = context;
this.checkInRec = checkInRec;
}
public View getView(int position, View convertView, ViewGroup parent)
{
if (convertView == null){
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
convertView = inflater.inflate(resourceId, parent, false);
}
TextView textViewName = (TextView) convertView.findViewById(R.id.tv_name);
TextView textViewCheckInDate = (TextView) convertView.findViewById(R.id.tv_checkindate);
TextView textViewPoints = (TextView) convertView.findViewById(R.id.tv_points);
ImageView imageViewIcon = (ImageView) convertView.findViewById(R.id.iv_icon);
CheckInRecord.CheckInRec checkInrec = checkInRec.get(position);
textViewName.setText(checkInrec.providerName);
textViewCheckInDate.setText(checkInrec.checkInDate);
textViewPoints.setText(checkInrec.providerPoints);
ImageLoader.getInstance().displayImage(checkInrec.providerIcon, imageViewIcon, Utility.displayImageOptions);
return convertView;
}
public int getIsPrize(int position) {return (this.checkInRec.get(position).isPrize);}
}
Data type
public class CheckInRecord {
public int userPoints;
public String userName;
public String gender;
public String birthDate;
public String location;
public String userIcon;
public List<CheckInRec> checkInRecList = new ArrayList<CheckInRec>();
public void addCheckInRec(String providerName, String providerLocation, String providerIcon,
String checkInDate, int providerPoints, int isPrize){
CheckInRec checkInRec = new CheckInRec();
checkInRec.providerName = providerName;
checkInRec.providerLocation = providerLocation;
checkInRec.providerIcon = providerIcon;
checkInRec.checkInDate = checkInDate;
checkInRec.providerPoints = providerPoints;
checkInRec.isPrize = isPrize;
checkInRecList.add(checkInRec);
}
public List<String> recImages(){
List<String> resultList = new ArrayList<String>();
if (this.checkInRecList == null){
return resultList;
}
for (CheckInRec rec : this.checkInRecList){
resultList.add(rec.providerIcon);
}
return resultList;
}
public class CheckInRec{
public String providerName;
public String providerLocation;
public String providerIcon;
public String checkInDate;
public int providerPoints;
public int isPrize;
}
}
Fragment
public class MeFragment extends Fragment implements ApiRequestDelegate {
private TextView textViewName;
private TextView textViewPoints;
private ProgressDialog progressDialog;
private RecordArrayAdapter recordArrayAdapter;
private List<CheckInRecord.CheckInRec> checkInRec = new ArrayList<CheckInRecord.CheckInRec>();
public MeFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AppDataManager.getInstance().setAllowCheckIn(true);
progressDialog = ProgressDialog.show(getActivity(), "", "");
ApiManager.getInstance().checkInHistories(AppDataManager.getInstance().getUserToken(), AppDataManager.getInstance().getUserPhone(),
Utility.getPictureSize(), this);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_me, container, false);
textViewName = (TextView) view.findViewById(R.id.tv_name);
textViewPoints = (TextView) view.findViewById(R.id.tv_points);
ListView listViewCheckInRec = (ListView) view.findViewById(R.id.lv_histories);
recordArrayAdapter = new RecordArrayAdapter(this.getActivity().getApplicationContext(), R.layout.row_record, checkInRec);
listViewCheckInRec.setAdapter(recordArrayAdapter);
return view;
}
#Override
public void setMenuVisibility(boolean menuVisible) {
super.setMenuVisibility(menuVisible);
if (menuVisible) {
refreshName();
}
}
public void refreshName() {
progressDialog = ProgressDialog.show(getActivity(), "", "");
AppDataManager dataManager = AppDataManager.getInstance();
ApiManager.getInstance().checkInHistories(dataManager.getUserToken(), dataManager.getUserPhone(), Utility.getPictureSize(), this);
}
#Override
public void apiCompleted(ApiResult apiResult, HttpRequest httpRequest) {
if (progressDialog!=null){
progressDialog.dismiss();
}
if (!apiResult.success){
ApiManager.handleMessageForReason(apiResult.failReason, getActivity());
return;
}
CheckInRecord checkInRecord = (CheckInRecord) apiResult.valueObject;
if (checkInRecord != null){
textViewName.setText(checkInRecord.userName);
textViewPoints.setText(String.format("积分%d分", checkInRecord.userPoints));
// this.checkInRec.clear();
// this.checkInRec.addAll(checkInRecord.checkInRecList);
//
// recordArrayAdapter.notifyDataSetChanged();
}
}
}

The problem is I cannot see my list in the app.
That is because checkInRec does now have any elements inside of it.
I can really tell that it is empty because you commented this out:
// this.checkInRec.clear(); //clear the old data from the list
// this.checkInRec.addAll(checkInRecord.checkInRecList); //add all the data inside the checkInRecord.checkInRecList
//
// recordArrayAdapter.notifyDataSetChanged(); //refreshing the ListView to display the new data
now what are those doing is that clearing the old list array and adding the new set of data from checkInRecord.checkInRecList and refreshing the ListView so those new data are implemented/shown in your ListView.
