How to call every object in adapter?

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;
SwipeRefreshLayout swipeProduct;
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;
}

ListView lost focus

I am working on an app in android studio.
My app has a listview, whiche has Edittext , textview and checkbox in its row.
my proplem is when I have more than five items in my listvew, the listview lost focus, for example: when I press on checkbox on the 6th item , the textview shows me the name from the first item.
I wish I could explain my proplem very well.
This is my adapter:
public AdapterListView(Context context, int resource, ArrayList<ObjectPeople> arraypeople) {
super(context, resource);
this.mContext = context;
this.arrayPeople = arraypeople;
this.inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(final int position, View convertView, ViewGroup parent)

holder.mission_image= (ImageView) convertView.findViewById(R.id.mission_image);
holder.cbm = (CheckBox) convertView.findViewById(R.id.checkbo);
convertView.setTag(holder);
holder.cbm.setOnClickListener(new View.OnClickListener() {
public void onClick(View v ) {
CheckBox cb = (CheckBox) v ;
final ObjectPeople person = arrayPeople.get(position);
if(cb.isChecked()) {
arrayPeople.get(position).checkbox= true;
int mis_tm=0;
try{ mis_tm= Integer.parseInt( holder.edit_time.getText().toString());}

#Override

missoins_time_calc= missoins_time_calc + arrPeople.get(i).time;}
}
if (hours2 == missoins_time_calc){
Gson gson = new Gson();
String jsonText = gson.toJson(selected_missions);
SharedPreferences.Editor editor = settings.edit();
editor.putString("selected_array", jsonText);
editor.commit();
Intent intent = new Intent(select.this, yourprogram.class);
startActivity(intent);
overridePendingTransition(R.anim.fade_in,R.anim.fade_out);
}
else if (hours2 > missoins_time_calc){
Toast.makeText(select.this, "بقي"+(-missoins_time_calc+ hours2)+" دقيقة ", Toast.LENGTH_SHORT).show();}
else if (hours2< missoins_time_calc){
Toast.makeText(select.this,"يوجد "+ (-hours2+missoins_time_calc)+" دقيقة زيادة على الوقت المخصص", Toast.LENGTH_SHORT).show();
}
/* ArrayList<missions> missionsList = dataAdapter.missionsList;
for(int i = 0; i< missionsList.size(); i++){
missions missions = missionsList.get(i);
if(missions.isSelected()){}}*/
}
});
}
}

I think the error is the way your arrayPeople List is being populated, if you say the sixth item gets you the first you can try reversing the order with
Collections.reverse(arrayPeople);
you can place this line of code below your holder.cbm.setOnClickListener on your adapter
Hope it helps.

Deleting listview item from database

I am deleting the title 2 list item item
But the last title gets deleted that is the title 8 gets deleted
When I then go back to the previous screen and reopen the list. The correct that is the 2nd item title 2 had been deleted.
Here is the DataAdapter

As I could not find any perfect solution i tried it in a different manner alough its a bit diffenrt from what i wanted i.e on click i used my displayListView() funtion and got the work done
ischeckboxVisible = true;
Runnable run = new Runnable() {
#Override
public void run() {
displayListView();
}
};
getActivity().runOnUiThread(run);
and coming to getView i have used:
if (!ischeckboxVisible)
{
holder.name.setVisibility(View.GONE);
}
if (ischeckboxVisible)
{
holder.name.setVisibility(View.VISIBLE);
}
so every time i do the click it changes the ischeckboxVisible to either true or false and initializes the displatListview() and it works.
I have had help from here Android hide and show checkboxes in custome listview on button click
Hope this might come in handy for some one out there.

Please check below code if it helps you,
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Database_Contact contact = (Database_Contact) contactlist.get(position);
contact.setSelected(!contact.isSelected());
if(contact.isSelected())
{
((CheckBox) view.findViewById(R.id.checkbox_all)).setVisibility(View.VISIBLE);
}
else
{
((CheckBox) view.findViewById(R.id.checkbox_all)).setVisibility(View.GONE);
}
}
});

Android getting unchecked checkbox in checklist after search in edittext

I have checklist with search functionality(used edittext). When I use it to search it shows filtered items so that I can make the selection that I want, it works properly. However, the checked items become unchecked when the search functionality reloads the list. I want the items selected before the search to remain selected. How can I fix this?
Here is my code:
public class Lab extends Fragment {
Button mViewBtn,msaveBtn;

ListView recycles the views every time its associated edit text's value is changed. That's why the Check-boxes does not retain their states.
To accomplish your task:
Store the checked items in an array.
When you click any checkbox in the listview, change the value of that particular item in the array.
Inside your getView method, check or uncheck the Check-boxes by reading the values from the array.
That way your checkboxes will retain their states. I hope this is clear.
