How to call every object in adapter?

How to call every object in adapter? - android

I have a list of array adapters that have the following layout which contains checkbox, textview increase, textview count, and textview decrease :
layout product adapter.
what the problem is how to call or implement clicklistener from ProdukActivity.java on each object that appears on the adapter. I just want to know how does it work with object in adapter so i can count the product price in every checkbox is checked.
Here is my adapter code :
public class ProductAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<ProductModel> productItems;
public ProductAdapter(Activity activity, List<ProductModel> productItems) {
this.activity = activity;
this.productItems = productItems;
}
#Override
public int getCount() {
return productItems.size();
}
#Override
public Object getItem(int location) {
return productItems.get(location);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_produk, null);
CheckBox namaProduk = (CheckBox) convertView.findViewById(R.id.checkBox_productName);
TextView kurangProduk = (TextView) convertView.findViewById(R.id.decrease_product);
TextView hitungProduk = (TextView) convertView.findViewById(R.id.count_product);
TextView tambahProduk = (TextView) convertView.findViewById(R.id.increase_product);
TextView hargaProduk = (TextView) convertView.findViewById(R.id.product_price);
ProductModel produk = productItems.get(position);
namaProduk.setText(produk.getProduct_name());
hargaProduk.setText(produk.getProduct_price());
return convertView;
}
}
and here is my ProdukActivity.java :
public class ProdukLaundry extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener {
ActionBar actionBar;
ListView listProduk;

List<ProductModel> productList = new ArrayList<ProductModel>();
ProductAdapter productAdapter;

Add listener for every object like below, inside getView of adapter. And inside the listener, do your handling
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_produk, null);
final CheckBox namaProduk = (CheckBox) convertView.findViewById(R.id.checkBox_productName);
TextView kurangProduk = (TextView) convertView.findViewById(R.id.decrease_product);
TextView hitungProduk = (TextView) convertView.findViewById(R.id.count_product);
TextView tambahProduk = (TextView) convertView.findViewById(R.id.increase_product);
TextView hargaProduk = (TextView) convertView.findViewById(R.id.product_price);
ProductModel produk = productItems.get(position);
namaProduk.setText(produk.getProduct_name());
hargaProduk.setText(produk.getProduct_price());
namaProduk.setOnCheckedChangeListener(
new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
//check here
}
}
}
);
kurangProduk.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
//do your task here
}
}
);
hitungProduk.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
//do your task here
}
}
);
tambahProduk.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
//do your task here
}
}
);
hargaProduk.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
//do your task here
}
}
);
return convertView;

Android - Delete an item from Custom Listview and update it when long clicked

In my App, I'm using Custom Listview, where I need to delete an item from Listview as well as corresponding row from CSV file simultaneously when Listview is long clicked.
My CSV file looks like this
2020/11/22,10:30PM,96.3°F,Normal,Body
2020/11/22,10:30PM,98.2°F,Normal,Body
2020/11/22,10:31PM,96.7°F,Normal,Body
2020/11/22,10:40PM,95.0°F,Normal,Body
For instance, if second item from Listview is removed when long clicked, the corresponding data row from CSV file above which is second row on CSV file should also be removed when Listview is long clicked.
Here's my Code:

You are only removing item from the loaded data set, therefore only list item is removing. You need to update your csv file on removal of list item
lvproducts.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
int which_item = position;
new AlertDialog.Builder(LogViewActivity.this)
.setTitle(getResources().getString(R.string.delete_log_file_title))
.setMessage(getResources().getString(R.string.delete_log_file_text) + "\n"
+ getResources().getString(R.string.file_name))
.setPositiveButton(android.R.string.ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
list.remove(which_item);
adapter.notifyDataSetChanged();
updateCSVFile();
}
})
.setNegativeButton(android.R.string.cancel, null)
.show();
return true;
}
});
public void updateCSVFile() {
// Write your logic her to update CSV file after item removal.

How to update the value of the textview inside the fragment on the click of the button present in the adapter class in android?

I have two buttons: + and -. I want that when I click on the button +, the value of the textview present in the fragment class (outside the listview) is changed. How can I do this ?

switch (view.getId()) {
case R.id.tv_checkout:
/* Fragment fragment = new LogIn();

// toolbar.setTitle("Checkout");
}
}
public void displayTotalAmount() {
int total = dbh.getTotalOfAmount();
mTvTotalPrice.setText(String.valueOf(total));
}
}
I want to change the value of the mTvTotalPric (Textview) on click of the button + and -, which is present at the listview. And the textview which the value I want to change is outside the listview.

In your Adapter class create one interface
Adapter.class
public class CartBaseAdapter extends BaseAdapter {
private Context mContext;
private ArrayList<PojoCart> mList;
private ViewHolder viewHolder;
private HashMap<String, Integer> mHashMap = new HashMap<String, Integer>();
private Integer total;
private DataBaseHandler dbh;
private int Id = 1;
private String value1, value2;
private int z;
private FragmentTransactionListener fragmentTransactionListener = (FragmentTransactionListener) new Cart();
private SendDataToFragment sendDataToFragment;
public CartBaseAdapter(FragmentCart fragmentCart, Context mContext, ArrayList<PojoCart> mList) {
this.mContext = mContext;
this.mList = mList;
dbh = new DataBaseHandler(mContext);
sendDataToFragment = (SendDataToFragment) fragmentCart;
}
//Interface to send data from adapter to fragment
public interface SendDataToFragment {
void sendData(String Data);
}
#Override
public int getCount() {
return mList.size();
}
#Override
public Object getItem(int position) {
return mList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.cart_item, parent, false);
viewHolder = new ViewHolder();
viewHolder.mImgItem = (ImageView) convertView.findViewById(R.id.cart_image);
viewHolder.mTvItemName = (TextView) convertView.findViewById(R.id.tv_item_name);
viewHolder.mTvItemPrice = (TextView) convertView.findViewById(R.id.tv_item_price);
viewHolder.mTvNumber = (TextView) convertView.findViewById(R.id.tv_number);
viewHolder.mBtnAdd = (Button) convertView.findViewById(R.id.btn_add);
viewHolder.mBtnMinus = (Button) convertView.findViewById(R.id.btn_sub);
viewHolder.mImgDelete = (ImageView) convertView.findViewById(R.id.img_del);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
convertView.setTag(viewHolder);
final PojoCart pojoCart = (PojoCart) getItem(position);
viewHolder.mTvItemName.setText(pojoCart.getmItemName());
viewHolder.mTvItemPrice.setText(pojoCart.getmItemPrice());
viewHolder.mImgItem.setImageBitmap(Utility.StringToBitMap(pojoCart.getmItemImage()));
viewHolder.mBtnAdd.setTag(pojoCart);
viewHolder.mBtnMinus.setTag(pojoCart);
viewHolder.mTvItemPrice.setTag(pojoCart);
viewHolder.mTvNumber.setTag(pojoCart);
viewHolder.mImgDelete.setTag(position);
if (pojoCart.getmQuantity() > 0) {
viewHolder.mTvNumber.setText("" + pojoCart.getmQuantity());
} else {
viewHolder.mTvNumber.setText("" + 0);
}
viewHolder.mBtnAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Send data via interface to your fragment
sendDataToFragment.sendData("Your Data");
//Your existing code
}
});
viewHolder.mBtnMinus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Send data via interface to your fragment
sendDataToFragment.sendData("Your Data");
//Your existing code
}
});
return convertView;
}
private class ViewHolder {
TextView mTvItemName, mTvItemPrice, mTvNumber;
ImageView mImgItem, mImgDelete;
Button mBtnAdd, mBtnMinus;
}
}
Inside your fragment implement that interface so as soon as your button is clicked in your adapter you will get the data inside your fragment.
Fragment.class
public class FragmentCart extends Fragment implements
View.OnClickListener, CartBaseAdapter.SendDataToFragment{
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.your_layout, null);
return rootView;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
CartBaseAdapter adapter = new CartBaseAdapter(FragmentCart.this, getActivity(), yourList);
}
#Override
public void onClick(View v) {
}
#Override
public void sendData(String Data) {
//set this data to your textView
}
}

Create a interface :
public interface MyListener {
// you can define any parameter as per your requirement
public void callback(View view, int value);
}
In your listview adapter use interface like below on click of button + or - like :
MyListener ml;
ml = (MyListener) context;
ml.callback(this, "success");
In activity implements MyListener than callback method override there and than you get performed action from fragment to activity.

Problem
First item in the list maps to 5th item. 2nd item to sixth item. I mean if I change radio button at the first item, Same radio button gets selected at the 5th list item also.
Any suggestions?
Is it because of recycling?
How do I resolve it?
I tried saving in Question object and retrieving it. I used pos to retrieve and set. But same problem still exist.

How to set listview row clickable only one time in android?

Explanation:
I have a listview in my fragment. When I click one of the row of the listview it goes to another activity.In listview,I got the data from the adapter.
Inside the adapter view,I set the setOnClick().
Problem is when I click one of the row multiple time it is opening multiple activity.I want to restrict only one time click on the particular row over the listview item.
Here is my fragment where I get the listview and set the adapter-
public class HomeFragment extends Fragment{
public HomeFragment() {
}

This adapter set the listrow item into listview.
In ScheduleAdapter.java i set the onclick() on the convertView in which i called a GetValue class which is only implement a Asynctask to get the data and called and intent then it goes to an activity.
Means HomeFragment->ScheduleAdapter->GetValue->Scorecard
Here,
HomeFragment is fragment which have listview
ScheduleAdpter is an adapter which set data to listview which reside in homefragment
GetValue is class which implement some important task and it passed an intent and goes to an activity(It's work as a background)
ScoreCard is my activity which called after click on the row of the listview which reside in HomeFragment.
Please, help me to solve out this problem.

You can use a flag in Listview click - isListClicked, and set flag value as false in onPostexecute method of Aysnc task class -GetValue
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(!isListClicked){
match_key = arr_matchKey.get(position);
MainActivity activity = (MainActivity) context;
GetValue gv = new GetValue(context);
gv.setFullUrl(match_key);
gv.setAccessToken(activity.getMyData());
gv.execute();
isListClicked = true;
}
}
});

If you want to prevent multiple activities being opened when the user spams with touches, add into your onClick event the removal of that onClickListener so that the listener won't exist after the first press.

Easy way is you can create a model class of your json object with those field you taken in holder class. And add one more boolean field isClickable with by default with true value.Now when user press a row for the first time you can set your model class field isClickable to false. Now second time when user press a row,you will get a position of row and you can check for isClickable. it will return false this time.
Model Class :
public class CountryInfoModel {
//other fields to parse json object
private boolean isClickable; //<- add one more extra field
public boolean isClickable() {
return isClickable;
}
public void setIsClickable(boolean isClickable) {
this.isClickable = isClickable;
}
}
listview click perform :
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//country_list is your list of model class List<CountryInfo>
if(country_list.get(position).isClickable())
{
//Perform your logic
country_list.get(position).setIsClickable(false);
}else{
//Do nothing : 2nd time click
}
}
});

Try creating your custom click listener for your listview and use it. In this way
public abstract class OnListItemClickListener implements OnItemClickListener {
private static final long MIN_CLICK_INTERVAL=600;
private long mLastClickTime;
public abstract void onListItemSingleClick(View parent, View view, int position, long id);
public OnListItemClickListener() {
// TODO Auto-generated constructor stub
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// TODO Auto-generated method stub
long currentClickTime=SystemClock.uptimeMillis();
long elapsedTime=currentClickTime-mLastClickTime;
mLastClickTime=currentClickTime;
if(elapsedTime<=MIN_CLICK_INTERVAL)
return;
onListItemSingleClick(parent, view, position, id);
}
}

Custom adapter and click on item in ListView

I have a problem with click on image in item in ListView. When I click I want to show layout which is gone. This is my code:
public class MyActualOffers extends BaseActivity {
private IResponse iResponse = null;
private ListView actualOffersList;
private ActualOffersListAdapter actualOffersAdapter;
private ArrayList<Offers> actualOffersFromJson;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_actual_offers);
actualOffersFromJson = new ArrayList<Offers>();
actualOffersList = (ListView) findViewById(R.id.actualOffersList);
iResponse = new IResponse() {
#Override
public void onResponse(JSONObject jObject) {
// messageUser = new User();
// messageUser.parseJsonResponse(jObject);
// usersMessages.add(messageUser);
// new DownloadImageTask(profileP)
// .execute("http://"+messageUser.getAvatarURL());
//
// messagesListView.refreshDrawableState();
// adapter.notifyDataSetChanged();
// adapter.notifyDataSetInvalidated();
}
#Override
public void onResponse(JSONArray jArray) {
try {
for (int i = 0; i < 3; i++) {
JSONObject messageJSON = (JSONObject)jArray.get(i);
Offers offer = new Offers();
offer.parseJsonResponse(messageJSON);
actualOffersFromJson.add(offer);
}
}catch (JSONException e) {
e.printStackTrace();
}
actualOffersAdapter = new ActualOffersListAdapter(getApplicationContext(), actualOffersFromJson);
actualOffersList.setAdapter(actualOffersAdapter);
// adapter = new MessagesListAdapter(getApplicationContext(), myMessagesList, usersMessages);
// messagesListView.setAdapter(adapter);
}
#Override
public void onError(JSONObject jObject) {
ErrorObject error = new ErrorObject();
error.parseJsonResponse(jObject);
error.showErrorDialog(MyActualOffers.this);
}
};
getActualMyOffers();
}
private void getActualMyOffers(){
SharedPreferencesData sharedData = new SharedPreferencesData();
String url = ConnectionParams.URL_OFFERS_FETCH_CURRENT_USER_OFFERS.replace("{0}", ""+"get");
String token = "?auth_token="+sharedData.getTokenData(getBaseContext());
connection.get(url + token + "&state=active", iResponse);
}
private class ActualOffersListAdapter extends BaseAdapter {
private Context context;
private ArrayList<Offers> offersList;
private LayoutInflater inflater;
private ViewHolder holder;
boolean isExpand = false;
public ActualOffersListAdapter(Context context, ArrayList<Offers> offersList) {
this.context = context;
this.offersList = offersList;
inflater = (LayoutInflater) getApplicationContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override

holder.cities = (TextViewWithImage) convertView.findViewById(R.id.actualOffersFromCityTXT);
holder.date = (TextView) convertView.findViewById(R.id.actualOffersCalendarTXT);
holder.type = (TextView) convertView.findViewById(R.id.actualOffersTripTypeTXT);
holder.shipment = (TextView) convertView.findViewById(R.id.actualOffersShipmentTypeTXT);

} else {

}
holder.cities.setText(offersList.get(position).getStart() + " [img src=ic_in_text_arrow/] " + offersList.get(position).getDestination());
holder.date.setText(offersList.get(position).getCreatedAt());
if(offersList.get(position).getFrequency().equals("once")){
holder.typeIcon.setImageDrawable(getResources().getDrawable(R.drawable.ic_in_text_once));
}else{
holder.typeIcon.setImageDrawable(getResources().getDrawable(R.drawable.ic_in_text_infinity));
}
holder.type.setText(offersList.get(position).getType());
holder.shipmentIcon.setImageDrawable(ShipmentTypeEnum.setIconForShipmentType(ShipmentTypeEnum.fromString(offersList.get(position).getShipmentType()), getApplicationContext()));

holder.deleteOffer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
holder.editOffer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
holder.addSimilar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
holder.addOpposite.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
holder.expandIcon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(isExpand){
holder.actualOffersExpandLayout.setVisibility(View.INVISIBLE);
isExpand = false;
}else{
holder.actualOffersExpandLayout.setVisibility(View.VISIBLE);
isExpand = true;
}
}
});
holder.infoIcon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
return convertView;
}
}
public static class ViewHolder {
public TextViewWithImage cities;
public TextView date;
public TextView type;
public TextView shipment;
public TextView transport;
public TextView deleteOffer;
public TextView editOffer;
public TextView addSimilar;
public TextView addOpposite;
public ImageView infoIcon;
public ImageView shipmentIcon;
public ImageView transportIcon;
public ImageView typeIcon;
public ImageView expandIcon;
public RelativeLayout actualOffersExpandLayout;
}
}
No when I click on holder.expandIcon in first item, expand layout show in last item of list. How can I create list with my item and properly working click on image in every item?

You are expanding the last item in the list because that was the last view retrieved by getView. The way the code is written now, there is only one isExpand value.
So you need to (a) add isExpand on the ViewHolder, and (b) use the ViewHolder attached to the View that was passed in the event handler. Like this:
holder.expandIcon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ViewHolder vh = (ViewHolder)v.getTag();
if(vh.isExpand){
vh.actualOffersExpandLayout.setVisibility(View.INVISIBLE);
vh.isExpand = false;
}else{
vh.actualOffersExpandLayout.setVisibility(View.VISIBLE);
vh.isExpand = true;
}
}
});
