適配器未獲得 boolean 值來設置微調器選擇

Question

我正在使用 firebase 回收器選項從 firebase 數據庫中檢索所需的數據，在本例中為 3 boolean 值。 在適配器中，我發現檢索到的所有 boolean 值都是假的。 但是，當我啟動活動和 select 微調器時，微調器在 firebase 數據庫中正確設置了 boolean 值。 此外，微調器上的選擇未根據數據正確設置，因為它檢索數據庫中的所有錯誤。

我附加了我的助手 class、適配器 onbindviewholder 和 onitemselected。

BookingModal.class

public class BookingModal {

    private String DATE;
    private String TIME;
    private String UID;
    private boolean approved;
    private boolean pending;
    private boolean rejected;

    public BookingModal(String DATE, String TIME, String UID, boolean approved, boolean pending, boolean rejected) {
        this.DATE = DATE;
        this.TIME = TIME;
        this.UID = UID;
        this.approved = approved;
        this.pending = pending;
        this.rejected = rejected;
    }
    public BookingModal(){}

    public String getDATE() {
        return DATE;
    }

    public void setDATE(String DATE) {
        this.DATE = DATE;
    }

    public String getTIME() {
        return TIME;
    }

    public void setTIME(String TIME) {
        this.TIME = TIME;
    }

    public String getUID() {
        return UID;
    }

    public void setUID(String UID) {
        this.UID = UID;
    }


    public boolean Approved() {
        return approved;
    }

    public void setApproved(boolean approved) {
        this.approved = approved;
    }

    public boolean Pending() {
        return pending;
    }

    public void setPending(boolean pending) {
        this.pending = pending;
    }

    public boolean Rejected() {
        return rejected;
    }

    public void setRejected(boolean rejected) {
        this.rejected = rejected;
    }
}

適配器 onbindviewholder class。

  @Override
    protected void onBindViewHolder(@NonNull BookingVH holder, int position, @NonNull BookingModal model) {

        holder.date.setText(model.getDATE());

        UserModal userModalDetail = findbyProperty(userModalList, model.getUID());
        if (userModalDetail != null) {
            holder.name.setText(userModalDetail.getName());
            holder.matric.setText(userModalDetail.getMatricnumber());
            onStatusSelected.onSelected(holder.status, userModalDetail.getUID(), model);
        }

        Log.d("booleanvalue", model.Pending() + " - "+model.Approved()+" - "+model.Rejected());



    }

onitemsselected 微調器

 @Override
    public void onSelected(Spinner v, String uid, BookingModal modal) {
        Log.d("modalboolean", String.valueOf(modal.Approved()));
        v.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                checker.clear();
                if (i == 0){
                    mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).child("isPending").setValue(true);
                    mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).child("isApproved").setValue(false);
                    mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).child("isRejected").setValue(false);

                } else if (i == 1){
                    mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).child("isApproved").setValue(true);
                    mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).child("isPending").setValue(false);
                    mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).child("isRejected").setValue(false);


                } else if (i == 2){
                    mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).child("isRejected").setValue(true);
                    mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).child("isApproved").setValue(false);
                    mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).child("isPending").setValue(false);

                }
                v.setSelection(i, true);

                Log.d("CheckerMap", checker.toString());
//                mDatabase.child("Bookings").child("Kompleks Sukan A").child("Pending").child(uid).updateChildren(checker);
            }

            @Override
            public void onNothingSelected(AdapterView<?> adapterView) {

            }
        });
    }

非常感謝您的幫助。 先感謝您 ！

Answer 1

在您的POJO類中，您已聲明

private boolean approved;
private boolean pending;
private boolean rejected;

在生成構建時，android 更改boolean類型的變量名稱。

為防止這種變化，您可以將 model 類保留在Proguard Rules中，如下所示：

-keep class com.example.myapplication.models.**

將所有類保留在models package 下。現在它不會更改變量的名稱。

Answer 2

我最終使用單個字符串作為狀態檢查。 改變它更容易與微調器一起使用。
