mproduct.remove(position) or notifyDataSetChange() does not work inside getView method

I have checked most of the places but i could not get the precise answer for this question.
problem in function : getView
What is the problem : When if condition gets true,
mproduct.remove((position));
notifyDataSetChanged();
both statement suppose to work.
// here mproduct is object of ArrayList;
If i write Log.e(); It displays promt message.
Thanks in advance.

Get checked items id from custom listview and pass them to new activity android

I'm developing an android app which has a custom listview with a checkbox. I want to pass all the checked items from one activity to another. how should I pass them? and where should I manage the checkbox (to get all the checked items) in the custom adapter or the activity?
Note: I retrieve all the data from my server using json response.
Here's my Model :
public class Groups {
public String name;
public boolean selected= false;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public boolean isSelected() {
return selected;
}
public void setSelected(boolean selected) {
this.selected = selected;
}
public Groups() {
}
}
My Adapter:
public class AdapterMainActivity extends BaseAdapter{
Activity activity;
private LayoutInflater inflater;
List<Groups> groupsList;
public AdapterMainActivity(Activity activity, List<Groups> groupses) {
this.activity = activity;
this.groupsList = groupses;
}
#Override
public int getCount() {
return groupsList.size();
}
#Override
public Object getItem(int position) {
return groupsList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final 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.custom_list, null);
TextView name = (TextView) convertView.findViewById(R.id.textViewName);
final CheckBox checkBox = (CheckBox) convertView.findViewById(R.id.checkBox);
final Groups groups = groupsList.get(position);
name.setText(groupsList.get(position).getName());
checkBox.setChecked(groups.selected);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
groups.selected = isChecked;
MainActivity.getInstance().updateArrayList(groupsList);
}
});
}
return convertView;
}
}
MainActivity:
public class MainActivity extends AppCompatActivity {
ListView listViewGroups;
Button buttonSentToActivity;
List<Groups> groupsList;
List<Groups> resultGroupList;
ArrayList<Boolean> areChecked;
List<String> finalArray;
private AdapterMainActivity adapterMainActivity;
static MainActivity yourActivity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
yourActivity = this;
groupsList= new ArrayList<Groups>();
resultGroupList= new ArrayList<Groups>();
ReadGroup(37);
adapterMainActivity = new AdapterMainActivity(this, groupsList);
listViewGroups = (ListView) findViewById(R.id.listViewGroups);
listViewGroups.setAdapter(adapterMainActivity);
buttonSentToActivity = (Button) findViewById(R.id.buttonSendTo2Activity);
buttonSentToActivity.setOnClickListener(buttonSentToActivityListener);
Log.e("Group list size ", String.valueOf(groupsList.size()));
finalArray = new ArrayList<>();
for (int i = 0; i < resultGroupList.size(); i++) {
if (resultGroupList.get(i).selected) {
finalArray.add(resultGroupList.get(i).getName());
Log.e("final array size", String.valueOf(finalArray.size()));
}
}
}
public void ReadGroup(long cid) {
Response.Listener<String> responseListener = new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response.toString());
JSONArray readArray = jsonObject.getJSONArray("groups");
for (int i = 0; i < readArray.length(); i++) {
Log.e("i is: ", String.valueOf(i));
JSONObject jssonRow = readArray.getJSONObject(i);
String groupName = jssonRow.getString("name");
Groups groups = new Groups();
groups.setName(groupName);
Log.e("NAME is: ", groupName);
groupsList.add(groups);
}
} catch (JSONException e) {
e.printStackTrace();
}
adapterMainActivity.notifyDataSetChanged();
}
};
Log.e("Client id is: ", String.valueOf(cid));
ReadGroupRequesr readGroupRequest = new ReadGroupRequesr(cid, responseListener);
RequestQueue queue = Volley.newRequestQueue(MainActivity.this);
queue.add(readGroupRequest);
Log.e("out of the loop", "");
}
public static MainActivity getInstance() {
return yourActivity;
}
public void updateArrayList(List<Groups> arrayList) {
this.resultGroupList = arrayList;
}
View.OnClickListener buttonSentToActivityListener = new View.OnClickListener() {
#Override
public void onClick(View view) {
//Bundle b= new Bundle();
//b.putStringArrayList("arrayList", (ArrayList<String>) finalArray);
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
intent.putStringArrayListExtra("arrayList", (ArrayList<String>) finalArray);
//intent.putExtras(b);
Log.e("final array size", String.valueOf(finalArray.size()));
startActivity(intent);
}
};
}

At the very first, manage your checkboxes :
In your activity class add a boolean array or arraylist having size same as your list array size and initialize it with all value as false initially :
String[] titlesArray;
ArrayList<Boolean> arrChecked;
// initialize arrChecked boolean array and add checkbox value as false initially for each item of listview
arrChecked = new ArrayList<Boolean>();
for (int i = 0; i < titles.size(); i++) {
arrChecked.add(false);
}
Now replace your adapter class with this :
class VivzAdapter extends ArrayAdapter<String> implements OnCheckedChangeListener {
Context context;
int[] images;
String[] titlesArray, descrptionArray;
List<Integer> positions = new ArrayList<Integer>();
ArrayList<Boolean> arrChecked;
VivzAdapter(Context context, String[] titles, int[] images, String[] description, ArrayList<Boolean> arrChecked) {
super(context, R.layout.single_row, R.id.textView1, titles);
this.context = context;
this.images = images;
this.titlesArray = titles;
this.descrptionArray = description;
this.arrChecked = arrChecked;
}
class MyViewHolder {
ImageView myImage;
TextView myTitle;
TextView myDescription;
CheckBox box;
MyViewHolder(View v) {
myImage = (ImageView) v.findViewById(R.id.imageView1);
myTitle = (TextView) v.findViewById(R.id.textView1);
myDescription = (TextView) v.findViewById(R.id.textView2);
box = (CheckBox) v.findViewById(R.id.checkBox1);
}
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
MyViewHolder holder = null;
if (row == null) {
// 1.ºtime
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//row contem RelativeLayout(root) em single_row.xml
row = inflater.inflate(R.layout.single_row, parent, false);
holder = new MyViewHolder(row);
row.setTag(holder);
//Log.d("VIVZ", "Creating a new Row");
} else {
//reciclamos aqui, qeremos usar antigo objecto holder
holder = (MyViewHolder) row.getTag();
//Log.d("VIVZ", "Recycling stuff");
}
holder.myImage.setImageResource(images[position]);
holder.myTitle.setText(titlesArray[position]);
holder.myDescription.setText(descrptionArray[position]);
//set position as id
holder.box.setId(position);
//set onClickListener of checkbox rather than onCheckedChangeListener
holder.box.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
int id = v.getId();
if (arrChecked.get(id)) {
//if checked, make it unchecked
arrChecked.set(id, false);
} else {
//if unchecked, make it checked
arrChecked.set(id, true);
}
}
});
//set the value of each checkbox from arrChecked boolean array
holder.box.setChecked(arrChecked.get(position));
return row;
}
}
After that, implement click listener of send button say btnSend button (I am considering that you are sending your data from one activity to another activity on click of send button) :
btnSend.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<String> arrTempList = new ArrayList();
for(int i=0; i<titles.size(); i++){
if(arrChecked.get(i) == true){
arrTempList.add(titles[i]);
}
}
// here you can send your arrTempList which is having checked items only
}
});

Here's the solution for this Question:
My adapter:
public class ChooseContactsAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
public ArrayList<Contacts> contactsList;
public CheckBox checkBoxAdapter;
public ChooseContactsAdapter(Activity activity, ArrayList<Contacts> group) {
this.activity = activity;
this.contactsList = group;
}
#Override
public int getCount() {
return contactsList.size();
}
#Override
public Object getItem(int position) {
return contactsList.get(position);
}
#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.custom_choose_contacts_sms,
null);
final TextView fNAme = (TextView) convertView.findViewById(R.id.textViewCustomSMSSelectContactFName);
TextView LName = (TextView) convertView.findViewById(R.id.textViewCustomSMSSelectContactLName);
checkBoxAdapter = (CheckBox) convertView.findViewById(R.id.checkBoxSelectContact);
checkBoxAdapter.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
CheckBox cb = (CheckBox) view;
Contacts contacts = (Contacts) cb.getTag();
contacts.setSelected(cb.isChecked());
Toast.makeText(activity.getApplicationContext(),
"Clicked on Checkbox: " + cb.getText() +
" is " + cb.isChecked(),
Toast.LENGTH_LONG).show();
}
});
final Contacts contacts = contactsList.get(position);
fNAme.setText(contacts.getContactFName());
LName.setText(contacts.getContactLName());
checkBoxAdapter.setChecked(contacts.isSelected());
checkBoxAdapter.setTag(contacts);
}
return convertView;
}
}
In my activity I have button to go from 1 activity to the 2 activity:
private View.OnClickListener buttonSubmitGroupListener =new View.OnClickListener() {
#Override
public void onClick(View view) {
List <Integer> contactsIDArray= new ArrayList<Integer>();
List<Contacts> arrayOfContacts= chooseContactsAdapter.contactsList;
for(int i=0; i< arrayOfContacts.size(); i++){
Contacts contacts= arrayOfContacts.get(i);
if(contacts.isSelected()==true){
contactsIDArray.add(contacts.getContactID());
}
}
for (int i = 0; i < contactsIDArray.size(); i++) {
Log.e("Id Array size ", String.valueOf(contactsIDArray.size()));
Log.e("Selected id ", String.valueOf(contactsIDArray.get(i)));
}
intent = new Intent(getApplicationContext(), SendSMSActivity.class);
Bundle b = new Bundle();
b.putIntegerArrayList("checkedContacts", (ArrayList<Integer>) contactsIDArray);
intent.putExtras(b);
startActivity(intent);
}
};
Second Activity add this code:
Bundle b = getIntent().getExtras();
List<Integer> result = new ArrayList<Integer>();
result = b.getIntegerArrayList("checkedContacts");

List view showing on another fragment

I'm using a view pager with a sliding panel inside, so when my panel is expanded it creates a request of users and instantiates viewholders to show them in the list view, the problem is that they get instantiated on wherever they want, how I can tell in what fragment it should be instantiated.
Here is my code:
#Override
public void onPanelAnchored(View panel) {
final View cView = panel;
EndpointInterface Service = ServiceAuthGenerator.createService(EndpointInterface.class);
currentID = sharedpreferences.getInt("CURRENTID", 0);
Call<List<Ride>> call = Service.getPassengers(currentRide);
call.enqueue(new Callback<List<Ride>>() {
#Override
public void onResponse(Response<List<Ride>> response, Retrofit retrofit) {
if (response.isSuccess() && !response.body().isEmpty()) {
dialogx.dismiss();
ArrayList<String> myUsersName = new ArrayList<>();
ArrayList<String> myUsersLastName = new ArrayList<>();
ArrayList<String> myUsersMapDirection = new ArrayList<>();
ArrayList<Integer> myUsersID = new ArrayList<>();
ArrayList<Boolean> myUsersRole = new ArrayList<>();
for (int i = 0; i < response.body().size(); i++) {
myUsersRole.add(response.body().get(i).getRole());
myUsersName.add(response.body().get(i).getUser().getFirst_name());
myUsersLastName.add(response.body().get(i).getUser().getLast_name());
myUsersMapDirection.add(getAdress(new LatLng(response.body().get(i).getOrigin_lat(), response.body().get(i).getOrigin_lng())));
myUsersID.add(response.body().get(i).getId());
currentName = myUsersName.get(i) + " " + myUsersLastName.get(i);
mMap.addMarker(new MarkerOptions().snippet(getAdress(new LatLng(response.body().get(Integer.valueOf(i)).getOrigin_lat(), response.body().get(Integer.valueOf(i)).getOrigin_lng()))).position(new LatLng(response.body().get(Integer.valueOf(i)).getOrigin_lat(), response.body().get(Integer.valueOf(i)).getOrigin_lng())).title(response.body().get(Integer.valueOf(i)).getUser().getFirst_name()).icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA)));
}
ListAdapter userAdapter = new CustomAdapterRequest(MainMenu.this, myUsersName, myUsersLastName, myUsersMapDirection, myUsersID, myUsersRole, currentRide);
ListView userListView = (ListView) cView.findViewById(R.id.listViewUserRequest);
userListView.setAdapter(userAdapter);
}
}
#Override
public void onFailure(Throwable t) {
Toast.makeText(getApplicationContext(), "no", Toast.LENGTH_SHORT).show();
}
});
}
Also, here is my adapter code:
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View row = convertView;
myViewHolder holder = null;
if (row == null) {
LayoutInflater customInflater = (LayoutInflater) contexto.getSystemService(contexto.LAYOUT_INFLATER_SERVICE);
row = customInflater.inflate(R.layout.custom_row_request, parent, false);
holder = new myViewHolder(row);
row.setTag(holder);
} else {
holder = (myViewHolder) row.getTag();
}
String singleNameItem = itemName.get(position);
String singleLastNameItem = itemLastName.get(position);
String singleDir = itemDirection.get(position);
Integer singleID = itemIDs.get(position);
Boolean singleRole = itemRoles.get(position);
holder.tv_name.setText(singleNameItem + " " + singleLastNameItem);
holder.tv_Direction.setText(singleDir);
holder.im_profilepic.setImageResource(R.mipmap.profile_photo3);
return row;
}
And my holder class.
class myViewHolder {
TextView tv_name;
TextView tv_Direction;
ImageView im_profilepic;
myViewHolder(View v) {
tv_name = (TextView) v.findViewById(R.id.nameText);
tv_Direction = (TextView) v.findViewById(R.id.originText);
im_profilepic = (ImageView) v.findViewById(R.id.ivImage);
}
}
This is the Fragment class
public class fragment1 extends Fragment {
public fragment1() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (container == null) {
return null;
}
return (CardView) inflater.inflate(R.layout.layout1, container, false);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
public void setTextDestination(String origin, String Destination, Long Date, String estimatedTime, boolean singleRole) {
TextView tv_Destination = (TextView) getView().findViewById(R.id.TextDestination);
TextView tv_origin = (TextView) getView().findViewById(R.id.TextOrigin);
TextView tv_Date = (TextView) getView().findViewById(R.id.textDatePager);
TextView tv_EstimatedTiem = (TextView) getView().findViewById(R.id.estimatedTimeRoute);
ImageView iv_roleType = (ImageView) getView().findViewById(R.id.ImgView_roleTypeLayout1);
tv_Destination.setText(Destination);
tv_origin.setText(origin);
iv_roleType.setImageResource(singleRole ? R.mipmap.steerorange3 : R.mipmap.handorange3);
tv_EstimatedTiem.setText(estimatedTime);
java.util.Date date = new Date(Date * 1000L);
DateFormat format = new SimpleDateFormat("dd-MM-yyyy hh:mm a");
format.setTimeZone(TimeZone.getDefault());
String formatted = format.format(date);
tv_Date.setText(formatted);
}
}
I created a list of fragment1 which is mu fragment class and added it to a list, then depending on how many items on the list I have is the number of instances I get, my set text function works correctly but I don't know how to do that with the list view!
Thanks! :D

moved the method that added the list view to the fragment that was instantiated.

how to listen on click of a button in array adapter

Android dynamic Multicolumn Listview
