How do I use variables of some class in a different class ( ConsumerDescAndEdit.java ) through onItemClickListener?

I need to display name, phoneNumber and accountNumber in EditText in the class ConsumerdescAndEdit, so how do pass these values when OnItemClickListener is executed?
ShowAll.java:
I have the ListView that inflated from CustomAdapter.
Intent intent = new Intent(ShowAll.this,ConsumerDescAndEdit.class);
startActivity(intent);
CustomAdapter.java:
public class CustomAdapter extends BaseAdapter {
Context mContext;
TextView nameView;
TextView phoneNumberView;
TextView accountView;
String name;
String phoneNumber;
String accountNumber;
ArrayList<Consumer> objects;
public CustomAdapter(Context context, int resource, ArrayList<Consumer> objects){
this.objects = objects;
this.mContext = context;
}
public CustomAdapter(){
}
#Override
public int getCount() {
return objects.size();
}
#Override
public Object getItem(int position) {
return objects.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Consumer consumer = (Consumer) getItem(position);
// Values to be displayed.
name = consumer.getName();
phoneNumber = consumer.getPhoneNumber();
accountNumber = consumer.getAccountNumber();
LayoutInflater inflater = LayoutInflater.from(mContext); // generate an inflater using context.
convertView = inflater.inflate(R.layout.details_layout,null); // inflate details_layout and store it in convertView.
nameView = convertView.findViewById(R.id.nameView);
phoneNumberView = convertView.findViewById(R.id.phoneNumberView);
accountView = convertView.findViewById(R.id.accountView);
nameView.setText(name);
phoneNumberView.setText(phoneNumber);
accountView.setText(accountNumber);
return convertView;
}
}
ConsumerDescAndEdit.java (where do I need to use variables):
public class ConsumerDescAndEdit extends AppCompatActivity {
Button updateButton;
EditText nameEditTextVar;
EditText phoneEditTextVar;
EditText accountEditTextVar;
// Variables to store user inputted data.
String nameEdit;
String phoneEdit;
String accountEdit;
DatabaseHelper dbHelper;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_consumer_desc_and_edit);
dbHelper = new DatabaseHelper(this);
updateButton = findViewById(R.id.updateButton);
nameEditTextVar = findViewById(R.id.nameEditScreen);
phoneEditTextVar = findViewById(R.id.phoneNumberEditScreen);
accountEditTextVar = findViewById(R.id.accountNumberEditScreen);
String s_intent = getIntent().getStringExtra("EXTRA_SESSION_ID");
nameEditTextVar.setText(s_intent);
updateButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
nameEdit = nameEditTextVar.getText().toString();
phoneEdit = phoneEditTextVar.getText().toString();
accountEdit = accountEditTextVar.getText().toString();
if (nameEdit.isEmpty() || phoneEdit.isEmpty() || accountEdit.isEmpty()) {
Toast.makeText(ConsumerDescAndEdit.this, "Data Insufficient", Toast.LENGTH_SHORT).show();
} else {
boolean b = dbHelper.updateData(nameEdit, phoneEdit, accountEdit);
if (b)
Toast.makeText(ConsumerDescAndEdit.this, "Data updated", Toast.LENGTH_SHORT).show();
else
Toast.makeText(ConsumerDescAndEdit.this, "Could not update data", Toast.LENGTH_SHORT).show();
}
}
});
}
}

When you create the Intent for the edit Activity, add the data from the selected item as "extras" to the Intent, like this:
Intent intent = new Intent(ShowAll.this,ConsumerDescAndEdit.class);
intent.putExtra("name", name);
intent.putExtra("phone", phone);
intent.putExtra("account", account);
startActivity(intent);
In the edit Activity, extract the data from the Intent like this:
String name = intent.getStringExtra("name");
String phone = intent.getStringExtra("phone");
String account = intent.getStringExtra("account");

Try below code
public class CustomAdapter extends BaseAdapter {
Context mContext;
TextView nameView;
TextView phoneNumberView;
TextView accountView;
String name;
String phoneNumber;
String accountNumber;
ArrayList<Consumer> objects;
private ItemClickListener itemClickListener;
public interface ItemClickListener {
void onItemClick(Consumer consumer);
}
public CustomAdapter(Context context, int resource, ArrayList<Consumer> objects, ItemClickListener itemClickListener) {
this.objects = objects;
this.mContext = context;
this.itemClickListener = itemClickListener;
}
public CustomAdapter() {
}
#Override
public int getCount() {
return objects.size();
}
#Override
public Object getItem(int position) {
return objects.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final Consumer consumer = (Consumer) getItem(position);
// Values to be displayed.
name = consumer.getName();
phoneNumber = consumer.getPhoneNumber();
accountNumber = consumer.getAccountNumber();
LayoutInflater inflater = LayoutInflater.from(mContext); // generate an inflater using context.
convertView = inflater.inflate(R.layout.details_layout, null); // inflate details_layout and store it in convertView.
nameView = convertView.findViewById(R.id.nameView);
phoneNumberView = convertView.findViewById(R.id.phoneNumberView);
accountView = convertView.findViewById(R.id.accountView);
nameView.setText(name);
phoneNumberView.setText(phoneNumber);
accountView.setText(accountNumber);
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (itemClickListener != null) {
itemClickListener.onItemClick(consumer);
}
}
});
return convertView;
}
}
In Activity do following
public class ConsumerActivity extends AppCompatActivity implements CustomAdapter.ItemClickListener {
CustomAdapter adapter;
ArrayList<Consumer> objects;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_consumer);
adapter = new CustomAdapter(this, objects, this);
}
#Override
public void onItemClick(Consumer consumer) {
Intent intent = new Intent(this, CustomerEdit.class);
intent.putExtra("Consumer", consumer);
startActivity(intent);
}
}

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 ?

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.

checkbox in listview to select and delete

This is my code I have one list view in the fragment which read sms using cursor I have set check box in adapter and I have 3 buttons outside the list view in main layout I need the followings
1.When I click one button it display checkbox in the list
2.when I select and scroll the list selected items wont disappears
3.select all button to select all in the list 4.delete button to delete the selected item remaining messages instantly updated.

Why a fragment is not executing?

I am trying to call a new fragment in android and when I am clicking the button Search it is working but after to execute the code:
Activity ac = (Activity) v.getContext();
AllFragment to = new AllFragment(null, false);
FragmentTransaction fragTransaction = ac.getFragmentManager().beginTransaction();
fragTransaction.replace(R.id.frame_container, to);
fragTransaction.addToBackStack(null);
fragTransaction.commit();
after it I see in the emulator the next screen:
then what I expected is a Listview of Products. The code I have in the fragment it is working perfect.
my fragment code is:
#SuppressLint("UseValueOf")
public class AllFragment extends ListFragment {

boolean esOferta = false;
public AllFragment(String codigo, boolean esOferta) {

this.codigo = codigo;
}

Why my fragment is not executing?

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.
