在我有关健康的应用程序中，有一个片段，医生可以在其中添加或拒绝患者到他/她自己的患者列表中。我使用recyclerView来显示所有患者，在每个项目中都有有关患者的信息，例如姓名，生日，城市，以及checkBox，它显示是否添加了患者。页面顶部还有另一个checkBox用于选择所有患者，还有添加和拒绝textViews。我想使用这些textViews来添加或拒绝从他们自己的checkBoxes中选择的患者。单击添加textView之后，患者将添加到Firebase数据库。我无法执行该功能。该怎么办？这是我的代码：
public class FragmentHastaBasvurulari extends Fragment {
private ArrayList<String> hastaAdi=new ArrayList<>();
private ArrayList<String> hastaOzellikleri=new ArrayList<>();
private ArrayList<String> hastaliklar=new ArrayList<>();
private ArrayList<String> hastaOnayi=new ArrayList<>();
private ArrayList<Users> hastalar=new ArrayList<>();
private FirebaseAuth mAuth;
private FirebaseUser firebaseUser;
private FirebaseDatabase database;
private DatabaseReference myRef;
private RecyclerView rvHastaBasvuru;
private CheckBox checkBoxHepsiniSec;
private TextView tvReddet,tvOnayla;
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
getActivity().setTitle("Hasta Başvuruları");
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_hasta_basvurulari, container, false);
mAuth=FirebaseAuth.getInstance();
firebaseUser=mAuth.getCurrentUser();
database=FirebaseDatabase.getInstance();
myRef=database.getReference();
rvHastaBasvuru=(RecyclerView) view.findViewById(R.id.rvHastaBasvuru);
checkBoxHepsiniSec=(CheckBox) view.findViewById(R.id.checkBoxHepsiniSec);
tvOnayla=(TextView) view.findViewById(R.id.tvOnayla);
tvReddet=(TextView) view.findViewById(R.id.tvReddet);
myRef.child("kullanicilar")
.child(firebaseUser.getUid()).child("hastalar").addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for(DataSnapshot ds: dataSnapshot.getChildren()){
EklenecekHasta eklenecekHasta = ds.getValue(EklenecekHasta.class);
DatabaseReference hastaRef= FirebaseDatabase.getInstance().getReference().child("kullanicilar").child(eklenecekHasta.getUserId());
hastaRef.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
if (dataSnapshot.exists()) {
Users hasta = dataSnapshot.getValue(Users.class);
String sehir, dogumTarihi,hastaliklar1;
if(hasta.getSehir().equals("Seçiniz")){
sehir="---";
} else {
sehir=hasta.getSehir();
}
if(hasta.getDogumtarihi().equals("../../....")){
dogumTarihi="---";
} else {
dogumTarihi=hasta.getDogumtarihi();
}
if(hasta.getHastaliklar().equals("")){
hastaliklar1="---";
} else {
hastaliklar1=hasta.getHastaliklar();
}
hastaAdi.add(hasta.getAd()+" "+hasta.getSoyad());
hastaOzellikleri.add(hasta.getCinsiyet()+" "+sehir+" "+dogumTarihi);
hastaliklar.add(hastaliklar1);
hastaOnayi.add(hasta.getOnay());
hastalar.add(hasta);
}
rvHastaBasvuru.setAdapter(adapter);
rvHastaBasvuru.setLayoutManager(new LinearLayoutManager(getContext()));
adapter.notifyDataSetChanged();
}
@Override
public void onCancelled(DatabaseError error) {
}
});
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
HastaListesiAdapter adapter= new HastaListesiAdapter(getContext(),hastaAdi,hastaOzellikleri,hastaliklar,hastaOnayi,hastalar);
});
tvOnayla.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
tvReddet.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
return view;
}
这是我的适配器类代码：
public class HastaListesiAdapter extends RecyclerView.Adapter<HastaListesiAdapter.ViewHolder>{
private static final String TAG="HekimListesiAdapter";
private ArrayList<String> hastaAdi=new ArrayList<>();
private ArrayList<String> hastaOzellikleri=new ArrayList<>();
private ArrayList<String> hastaliklar=new ArrayList<>();
private ArrayList<String> hastaOnayi=new ArrayList<>();
private ArrayList<Users> hastalar=new ArrayList<>();
private Context myContext;
public HastaListesiAdapter(Context myContext, ArrayList<String> hastaAdi, ArrayList<String> hastaOzellikleri,
ArrayList<String> hastaliklar,ArrayList<String> hastaOnayi,ArrayList<Users> hastalar) {
this.hastaAdi = hastaAdi;
this.hastaOzellikleri = hastaOzellikleri;
this.myContext = myContext;
this.hastaliklar=hastaliklar;
this.hastaOnayi=hastaOnayi;
this.hastalar=hastalar;
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int i) {
View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.hasta_item,parent,false);
ViewHolder holder=new ViewHolder(view);
return holder;
}
@Override
public void onBindViewHolder(@NonNull final ViewHolder holder, final int i) {
holder.itemHastaAd.setText(hastaAdi.get(i));
holder.itemHastaOz.setText(hastaOzellikleri.get(i));
holder.itemHastaliklar.setText(hastaliklar.get(i));
//Hasta hekim tarafından onaylanmış mı onaylanmamış mı
if(hastaOnayi.get(i).equals("evet")){
holder.checkBoxHastaSec.setChecked(true);
} else if(hastaOnayi.get(i).equals("hayır")){
holder.checkBoxHastaSec.setChecked(false);
}
// CheckBox ın tıklanması üzerine yapılacak işlem
holder.checkBoxHastaSec.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
String secilimi;
if(buttonView.isChecked()){
secilimi="evet";
} else {
secilimi="hayır";
}
}
});
}
@Override
public int getItemCount() {
return hastaAdi.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView itemHastaAd,itemHastaOz,itemHastaliklar;
CheckBox checkBoxHastaSec;
public ViewHolder(@NonNull View itemView) {
super(itemView);
itemHastaAd=itemView.findViewById(R.id.itemHastaAd);
itemHastaOz= itemView.findViewById(R.id.itemHastaOz);
itemHastaliklar=itemView.findViewById(R.id.itemHastaliklar);
checkBoxHastaSec=itemView.findViewById(R.id.checkBoxHastaSec);
}
}
答案 0 :(得分：0)
我建议您用自定义模型的一个arrayList替换字符串arrayLists，并且您也可以在复选框中使用一个布尔值表示数据。例如，创建一个这样的模型：
class YourModel()
{
String hastaAdi;
String hastaOzellikleri;
//... another variables
Boolean isAdded;
//... set & get or other methods
}
现在，您应该将ArrayList传递给适配器，并通过此arrayList设置recyclerView小部件的值。然后，您可以使用iwego布尔值初始化或更改checkBox的值。
