Android studio Hide and Show buttons from a condition

Question

my android app needs a function that has a button that needs to show and hide based on one TextView. Here is my code and ill explain further.

public class currentCar extends Fragment implements AsyncResponse, AdapterView.OnItemClickListener {
final String TAG = this.getClass().getName();
private ArrayList<AcceptCars> carList;
private ListView lvCurrent;
private FunDapter<AcceptCars> adapter;
SharedPreferences pref;

public currentCar() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View v =  inflater.inflate(R.layout.fragment_current_car, container, false);

    ImageLoader.getInstance().init(UILConfig.config(getActivity()));

    lvCurrent = (ListView) v.findViewById(R.id.lvCurrent);

    pref = getActivity().getSharedPreferences("Login.conf", Context.MODE_PRIVATE);
    Log.d(TAG, pref.getString("username",""));

    PostResponseAsyncTask taskRead = new PostResponseAsyncTask(getActivity(), this);

    taskRead.execute("http://carkila.esy.es/carkila/current.php?acceptCarOwner="+pref.getString("username",""));

    return v;
}

@Override
public void processFinish(String s) {
    carList = new JsonConverter<AcceptCars>().toArrayList(s, AcceptCars.class);

    BindDictionary<AcceptCars> dict = new BindDictionary<AcceptCars>();

    dict.addDynamicImageField(R.id.ivImg1, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return item.acceptImage;
        }
    }, new DynamicImageLoader() {
        @Override
        public void loadImage(String url, ImageView view) {

            ImageLoader.getInstance().displayImage(url, view);
        }
    });
    dict.addStringField(R.id.tvCarModel, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Car Model: " + item.acceptModel;
        }
    });
    dict.addStringField(R.id.tvResDate, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Date: " + item.acceptDate;
        }
    });
    dict.addStringField(R.id.tvResTime, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Time: " + item.acceptTime;
        }
    });
    dict.addStringField(R.id.tvResLocation, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Location: " + item.acceptResLocation;
        }
    });
    dict.addStringField(R.id.tvCarType, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Car Type: " + item.acceptType;
        }
    });
    dict.addStringField(R.id.tvCapacity, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Capacity: " + item.acceptCapacity;
        }
    });
    dict.addStringField(R.id.tvFuelType, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Fuel Type: " + item.acceptFuelType;
        }
    });
    dict.addStringField(R.id.tvPlateNumber, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Plate Number: " + item.acceptPlateNumber;
        }
    });
    dict.addStringField(R.id.tvPoster, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Posted by : " + item.acceptCarOwner;
        }
    });
    dict.addStringField(R.id.tvRenter, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Rented by: "+ item.renters;
        }
    });
    dict.addStringField(R.id.tvDestination, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Destination: " + item.acceptDestination;
        }
    });

    dict.addStringField(R.id.tvResPrice, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Destination: " + item.acceptPrice;
        }
    });
    dict.addStringField(R.id.tvresID, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return ""+ item.acceptedID;
        }
    });
    dict.addStringField(R.id.tvstatus, new StringExtractor<AcceptCars>() {
        @Override
        public String getStringValue(AcceptCars item, int position) {
            return "Status: "+ item.payment;
        }
    });

    adapter = new FunDapter<>(
            getActivity(), carList, R.layout.layout_rented, dict);
    lvCurrent.setAdapter(adapter);
    lvCurrent.setOnItemClickListener(this);
}

@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
    AcceptCars selectedCars = carList.get(i);
        Intent in = new Intent(getActivity(), ownerStatus.class);
        in.putExtra("cars", selectedCars);
        startActivity(in);
}
}

On the start of this listView the item.payment is "unpaid" and it will go to ownerStatus.class

        }
    });
}
}

And on here. When the Cars.payment is unpaid the btnPaid will show and hide the btnDone but when the Cars.payment is paid the btnPaid will hide and the btnDone will now Hide. Hope you understand how i explained and help me with my problem. Thanks sir :)

@brandall - I can hide a button from xml but I can't do it how I expounded on my question sir. — Batz Pogi, Sep 30 '16 at 14:34
@Code-Apprentice - But that's the problem why I'm asking sir. I don't know how. Hahaha! — Batz Pogi, Sep 30 '16 at 14:34
So, you just want this? http://stackoverflow.com/q/4127725/1256219 — brandall, Sep 30 '16 at 14:40
@brandall - I tried that one but when im back from the listview and click an item. I still dont get what I want to achieve. — Batz Pogi, Sep 30 '16 at 14:49
You need to explain further - when you click a listview item, you want to show or hide a button depending on the paid condition? — brandall, Sep 30 '16 at 14:51
@brandall - when `paid = unpaid` btnPaid will show but when the `paid = paid` btnDone will show... — Batz Pogi, Sep 30 '16 at 15:02

From your comments, are you saying you need to check:

if(Cars.payment) {
    btnDone.setVisibility(View.GONE);
    btnPaid.setVisibility(View.VISIBLE);
 } else {
    btnPaid.setVisibility(View.GONE);
    btnDone.setVisibility(View.VISIBLE);
 }

on the class with listview or in the `ownerStatus`? – Batz Pogi Sep 30 '16 at 15:04
@BatzPogi Wherever you are checking the paid status and initially showing the views – brandall Sep 30 '16 at 15:05
@BatzPogi Good! Look at David's answer for a more concise way of writing the code, once you are comfortable with how you are structuring your conditions. – brandall Sep 30 '16 at 15:10

you pass the selected car in the intent and get in the OwnerStatus.class. So where you set the values from selected car there you just check the car.payment and set the visibility of the button behalf of the status.

example:-

you have to declare the button before that code like below:-

 btnPaid = (Button) findViewById(R.id.btnPaid);
 btnDone = (Button) findViewById(R.id.btnDone);


if (Cars != null) {
        tvresID.setText("" + Cars.acceptedID);
        tvCarModel.setText(Cars.acceptModel);
        tvCarType.setText(Cars.acceptType);
        tvCapacity.setText(Cars.acceptCapacity);
        tvFuelType.setText(Cars.acceptFuelType);
        tvPlateNumber.setText(Cars.acceptPlateNumber);
        tvResDate.setText(Cars.acceptDate);
        tvResTime.setText(Cars.acceptTime);
        tvResLocation.setText(Cars.acceptResLocation);
        tvPoster.setText(Cars.acceptCarOwner);
        tvRenter.setText(Cars.renters);
        tvDestination.setText(Cars.acceptDestination);
        tvPrice.setText(Cars.acceptPrice);
        tvPaymentStatus.setText(Cars.payment);
        tvStatus.setText(Cars.payment);

        ImageLoader.getInstance().displayImage(Cars.acceptImage, ivImage);

       //here you just check the status of the car payment

       if(Car.payment.equalsignorecase("unpaid"))
      {
       btnDone.setVisibility(View.Gone);
       btnPaid.setVisibility(View.VISIBLE);
      }
      else
      {
      // what you want to do here
      }


    }
