I write a code for BottomDialogFragment But the issue is when someone chooses 10₹ the program run like a loop and subtract money from his wallet continously untill it will be 0.
Main issue that was when user clicks on join that was executed continously but I never used the Loop for the code please resolve this issue I'm not able to figure out the issue
Here is My BottomRedFragment.java
public class BottomRedFragment extends BottomSheetDialogFragment {
FragmentBottomRedBinding binding;
ProgressDialog progressDialog;
// FirebaseDatabase firebaseDatabase;
// DatabaseReference databaseReference;
// DatabaseReference price;
int quantity = 1;
String coin;
int icoin = 0;
String mobile;
int ivalue;
int tcmoney;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
binding = FragmentBottomRedBinding.inflate(inflater, container, false);
View view = binding.getRoot();
String qty = String.valueOf(quantity);
binding.quantityRed.setText(qty);
mobile = getActivity().getIntent().getStringExtra("mobile");
progressDialog = new ProgressDialog(getActivity());
progressDialog.setTitle("Joining Red");
progressDialog.setMessage("Please Wait");
MaterialButtonToggleGroup toggleGroup = binding.toggleButton;
int buttonId = toggleGroup.getCheckedButtonId();
MaterialButton button = toggleGroup.findViewById(buttonId);
toggleGroup.addOnButtonCheckedListener(new MaterialButtonToggleGroup.OnButtonCheckedListener() {
@Override
public void onButtonChecked(MaterialButtonToggleGroup group, int checkedId, boolean isChecked) {
if (group.getCheckedButtonId() == R.id.btn1) {
icoin = 10;
int ten = icoin * quantity;
coin = String.valueOf(ten);
binding.totalPriceMoney.setText(coin);
} else if (group.getCheckedButtonId() == R.id.btn2) {
icoin = 50;
int fifty = icoin * quantity;
coin = String.valueOf(fifty);
binding.totalPriceMoney.setText(coin);
} else if (group.getCheckedButtonId() == R.id.btn3) {
icoin = 100;
int hundred = icoin * quantity;
coin = String.valueOf(hundred);
binding.totalPriceMoney.setText(coin);
} else {
Toast.makeText(getActivity(), "Please Choose a valid amount", Toast.LENGTH_SHORT).show();
}
}
});
binding.subtractRed.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
decrement();
}
});
binding.addRed.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
increment();
}
});
binding.joinRed.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
tcmoney = Integer.parseInt(binding.totalPriceMoney.getText().toString());
if (tcmoney == 0 || icoin == 0) {
Toast.makeText(getActivity(), "Please choose Correct Values", Toast.LENGTH_SHORT).show();
} else {
progressDialog.show();
progressDialog.setCanceledOnTouchOutside(false);
joinVerify();
}
}
});
return view;
}
private void joinVerify() {
Toast.makeText(getContext(), mobile, Toast.LENGTH_SHORT).show();
DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference("Users").child(mobile).child("wallet");
databaseReference.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot snapshot) {
String value = snapshot.getValue(String.class);
ivalue = Integer.parseInt(value);
if (tcmoney > ivalue) {
progressDialog.dismiss();
Toast.makeText(getContext(), "Insufficient Funds", Toast.LENGTH_LONG).show();
} else {
int ijoin = ivalue - tcmoney;
String join = String.valueOf(ijoin);
databaseReference.setValue(join);
Toast.makeText(getActivity(), "Joined Successfully", Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
}
}
@Override
public void onCancelled(@NonNull DatabaseError error) {
}
});
}
private void increment() {
quantity++;
String s = String.valueOf(quantity);
binding.quantityRed.setText(s);
int calc = icoin * quantity;
coin = String.valueOf(calc);
binding.totalPriceMoney.setText(coin);
}
private void decrement() {
quantity = quantity > 1 ? --quantity : 1;
String s = String.valueOf(quantity);
binding.quantityRed.setText(s);
int calc = icoin * quantity;
coin = String.valueOf(calc);
binding.totalPriceMoney.setText(coin);
}
}
