問題描述

我正在創建一個注冊布局。 因為要放在一個布局中的信息太多，所以我需要使用兩個

當用戶選擇REGISTER按鈕時，我想顯示布局 1，將數據保存到 firebase，然后當他們選擇肯定按鈕時，它會關閉布局 1 並顯示布局 2。

我怎樣才能做到這一點？

我有兩個對話框：

顯示車輛詳情

AlertDialog.Builder alert_dialog = new AlertDialog.Builder(this);
    alert_dialog.setTitle("VEHICLE DETAILS");
    alert_dialog.setMessage("Please, fill in the following:");
    LayoutInflater inflate = LayoutInflater.from(this);
    View vehicle_details = inflate.inflate(R.layout.layout_vehicle_details, null);

    final MaterialEditText edtYear = vehicle_details.findViewById(R.id.year);
    final MaterialEditText edtCMNM = vehicle_details.findViewById(R.id.cmnm);
    final MaterialEditText edtPlate = vehicle_details.findViewById(R.id.plate);

    alert_dialog.setView(vehicle_details);

    alert_dialog.setPositiveButton("SUBMIT", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();

            // check validation
            if (TextUtils.isEmpty(edtYear.getText().toString())) {
                Snackbar.make(rootLayout, "Please enter year of your vehicle", Snackbar
                        .LENGTH_SHORT).show();

                return;
            }

            if (TextUtils.isEmpty(edtCMNM.getText().toString())) {
                Snackbar.make(rootLayout, "Please enter the Color, Make and Model of your vehicle",
                        Snackbar.LENGTH_SHORT).show();

                return;
            }

            if (TextUtils.isEmpty(edtPlate.getText().toString())) {
                Snackbar.make(rootLayout, "Please enter your license plate number", Snackbar
                        .LENGTH_SHORT).show();

                return;
            }

            // save to firebase/ Users/Drivers ...

            details = users;
            details.addValueEventListener(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot snapshot) {
                    // get drivers id
                    for (DataSnapshot ss : snapshot.getChildren()) {
                        String id = ss.getKey();

                        String year = edtYear.getText().toString();
                        String cmnm = edtCMNM.getText().toString();
                        String plate = edtPlate.getText().toString();

                        Log.e(TAG, "year: " + year + ", cmnm: " + cmnm + ", plate: " + plate);

                        // data sent
                        details.child(id).child("year").setValue(year);
                        details.child(id).child("cmnm").setValue(cmnm);
                        details.child(id).child("plate").setValue(plate);
                    }
                }

                @Override
                public void onCancelled(DatabaseError databaseError) {

                }
            });
        }
    });

    AlertDialog dialog = alert_dialog.create();
    dialog.show();
}

顯示注冊對話框

final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("REGISTER");
    builder.setMessage("Please use email to register");
    LayoutInflater inflater = LayoutInflater.from(this);
    View register_layout = inflater.inflate(R.layout.layout_register, null);

    final MaterialEditText edtEmail = register_layout.findViewById(R.id.email);
    final MaterialEditText edtPassword = register_layout.findViewById(R.id.password);
    final MaterialEditText edtName = register_layout.findViewById(R.id.usersname);
    final MaterialEditText edtPhone = register_layout.findViewById(R.id.cell);

    final MaterialAnimatedSwitch policies_switch = register_layout.findViewById(R.id.policies_switch);

    builder.setView(register_layout);

    builder.setPositiveButton("REGISTER", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(final DialogInterface dialog, int which) {
            dialog.dismiss();

            // check validation
            if (TextUtils.isEmpty(edtEmail.getText().toString())) {
                Snackbar.make(rootLayout, "Please enter email address", Snackbar
                        .LENGTH_SHORT).show();

                return;
            }

            if (TextUtils.isEmpty(edtPhone.getText().toString())) {
                Snackbar.make(rootLayout, "Please enter phone number", Snackbar
                        .LENGTH_SHORT).show();

                return;
            }

            if (TextUtils.isEmpty(edtPassword.getText().toString())) {
                Snackbar.make(rootLayout, "Please enter password", Snackbar
                        .LENGTH_SHORT).show();

                return;
            }

            if (edtPassword.getText().toString().length() < 6) {
                Snackbar.make(rootLayout, "Password too short !!!", Snackbar
                        .LENGTH_SHORT).show();

                return;
            }


            // Register new user
            auth.createUserWithEmailAndPassword(edtEmail.getText().toString(),
                    edtPassword.getText().toString())
                    .addOnSuccessListener(new OnSuccessListener<AuthResult>() {
                        @Override
                        public void onSuccess(AuthResult authResult) {
                            // Save user to db
                            Driver driver = new Driver();
                            driver.setEmail(edtEmail.getText().toString());
                            driver.setUsersname(edtName.getText().toString());
                            driver.setCell(edtPhone.getText().toString());
                            driver.setPassword(edtPassword.getText().toString());
                            driver.setRates("4.5"); // TODO: Default added

                            // use uid to key
                            users.child(FirebaseAuth.getInstance().getCurrentUser().getUid())
                                    .setValue(driver)
                                    .addOnSuccessListener(new OnSuccessListener<Void>() {
                                        @Override
                                        public void onSuccess(Void aVoid) {
                                            Snackbar.make(rootLayout, "Registration successful !!!",
                                                    Snackbar.LENGTH_SHORT).show();
                                        }
                                    })

                                    .addOnFailureListener(new OnFailureListener() {
                                        @Override
                                        public void onFailure(@NonNull Exception e) {
                                            Snackbar.make(rootLayout, "Failed" + e.getMessage(),
                                                    Snackbar.LENGTH_SHORT).show();
                                        }
                                    });
                        }
                    })

                    .addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            Snackbar.make(rootLayout, "Failed" + e.getMessage(),
                                    Snackbar.LENGTH_SHORT).show();
                        }
                    });
        }
    });

    builder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });

    final AlertDialog dialog = builder.create();

    /* If switch is on, enable REGISTER button */
    policies_switch.setOnCheckedChangeListener(new MaterialAnimatedSwitch.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(boolean isChecked) {
            if (isChecked) {
                dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(true); // if checked, enable
            }
        }
    });

    dialog.show();

    dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false); // set disabled by default

}

現在，當我單擊“ Register按鈕時，它會顯示第二個布局 showRegisterDialog。

我希望它首先顯示showVehicleDetails ，當我選擇肯定按鈕SUBMIT它應該顯示showRegisterDetails

當我運行代碼時，在onCreate ：

btnRegister.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            showVehicleDetails();
            showRegisterDialog();
        }
    });

編輯

這就是當我按下注冊按鈕時發生的情況，它堅持這個而不是關閉

好吧，我不推薦它像這樣，我更喜歡它像@Tamir 在他的回答中表達的那樣更干凈，但是這是您需要做的，以便您以后可以重構更干凈、更簡單的代碼，以幫助您拆分和調試容易地。

正如我在此處的評論中所解釋的，您將更改關於 showVehicleDetails 的修改：

AlertDialog.Builder alert_dialog = new AlertDialog.Builder(this);
alert_dialog.setTitle("VEHICLE DETAILS");
alert_dialog.setMessage("Please, fill in the following:");
LayoutInflater inflate = LayoutInflater.from(this);
View vehicle_details = inflate.inflate(R.layout.layout_vehicle_details, null);

final MaterialEditText edtYear = vehicle_details.findViewById(R.id.year);
final MaterialEditText edtCMNM = vehicle_details.findViewById(R.id.cmnm);
final MaterialEditText edtPlate = vehicle_details.findViewById(R.id.plate);

alert_dialog.setView(vehicle_details);

alert_dialog.setPositiveButton("SUBMIT", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(final DialogInterface dialog, int which) {


        // check validation
        if (TextUtils.isEmpty(edtYear.getText().toString())) {
            Snackbar.make(rootLayout, "Please enter year of your vehicle", Snackbar
                    .LENGTH_SHORT).show();

            return;
        }

        if (TextUtils.isEmpty(edtCMNM.getText().toString())) {
            Snackbar.make(rootLayout, "Please enter the Color, Make and Model of your vehicle",
                    Snackbar.LENGTH_SHORT).show();

            return;
        }

        if (TextUtils.isEmpty(edtPlate.getText().toString())) {
            Snackbar.make(rootLayout, "Please enter your license plate number", Snackbar
                    .LENGTH_SHORT).show();

            return;
        }

        // save to firebase/ Users/Drivers ...

        details = users;
        details.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot snapshot) {
                // get drivers id
                for (DataSnapshot ss : snapshot.getChildren()) {
                    String id = ss.getKey();

                    String year = edtYear.getText().toString();
                    String cmnm = edtCMNM.getText().toString();
                    String plate = edtPlate.getText().toString();

                    Log.e(TAG, "year: " + year + ", cmnm: " + cmnm + ", plate: " + plate);

                    // data sent
                    details.child(id).child("year").setValue(year);
                    details.child(id).child("cmnm").setValue(cmnm);
                    details.child(id).child("plate").setValue(plate);
                }
                 showRegisterDialog();
                 dialog.dismiss();

            }

            @Override
            public void onCancelled(DatabaseError databaseError) {

            }
        });
    }
});
AlertDialog dialog = alert_dialog.create();
dialog.show();}

以下是您將更改的關於 showRegisterDialogue 的修正：

final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("REGISTER");
builder.setMessage("Please use email to register");
LayoutInflater inflater = LayoutInflater.from(this);
View register_layout = inflater.inflate(R.layout.layout_register, null);

final MaterialEditText edtPassword = register_layout.findViewById(R.id.password);
final MaterialEditText edtName = register_layout.findViewById(R.id.usersname);
final MaterialEditText edtPhone = register_layout.findViewById(R.id.cell);

final MaterialAnimatedSwitch policies_switch = register_layout.findViewById(R.id.policies_switch);

builder.setView(register_layout);

builder.setPositiveButton("REGISTER", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(final DialogInterface dialog, int which) {

        // check validation
        if (TextUtils.isEmpty(edtEmail.getText().toString())) {
            Snackbar.make(rootLayout, "Please enter email address", Snackbar
                    .LENGTH_SHORT).show();

            return;
        }

        if (TextUtils.isEmpty(edtPhone.getText().toString())) {
            Snackbar.make(rootLayout, "Please enter phone number", Snackbar
                    .LENGTH_SHORT).show();

            return;
        }

        if (TextUtils.isEmpty(edtPassword.getText().toString())) {
            Snackbar.make(rootLayout, "Please enter password", Snackbar
                    .LENGTH_SHORT).show();

            return;
        }

        if (edtPassword.getText().toString().length() < 6) {
            Snackbar.make(rootLayout, "Password too short !!!", Snackbar
                    .LENGTH_SHORT).show();

            return;
        }


        // Register new user
        auth.createUserWithEmailAndPassword(edtEmail.getText().toString(),
                edtPassword.getText().toString())
                .addOnSuccessListener(new OnSuccessListener<AuthResult>() {
                    @Override
                    public void onSuccess(AuthResult authResult) {
                        // Save user to db
                        Driver driver = new Driver();
                        driver.setEmail(edtEmail.getText().toString());
                        driver.setUsersname(edtName.getText().toString());
                        driver.setCell(edtPhone.getText().toString());
                        driver.setPassword(edtPassword.getText().toString());
                        driver.setRates("4.5"); // TODO: Default added

                        // use uid to key
                        users.child(FirebaseAuth.getInstance().getCurrentUser().getUid())
                                .setValue(driver)

                                        dialog.dismiss();
                                    }
                                })

                                .addOnFailureListener(new OnFailureListener() {
                                    @Override
                                    public void onFailure(@NonNull Exception e) {
                                        Snackbar.make(rootLayout, "Failed" + e.getMessage(),
                                                Snackbar.LENGTH_SHORT).show();
                                        dialog.dismiss();
                                    }
                                });
                    }
                })

                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Snackbar.make(rootLayout, "Failed" + e.getMessage(),
                                Snackbar.LENGTH_SHORT).show();
                                        dialog.dismiss();
                    }
                });
    }
});

builder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        dialog.dismiss();
    }
});

final AlertDialog dialog = builder.create();

/* If switch is on, enable REGISTER button */
policies_switch.setOnCheckedChangeListener(new MaterialAnimatedSwitch.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(boolean isChecked) {
        if (isChecked) {
            dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(true); // if checked, enable
        }
    }
});

dialog.show();

dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false); // set disabled by default

 }

對於 ClickListener，您只需刪除 showRegisterDialogue 就可以了，就像這樣

btnRegister.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        showVehicleDetails();
    }
});

為此，我將使用 2 個自定義對話框類。

每個對話框都有他的類和布局，現在我們需要這樣做：

  • 顯示對話框 A

  • 將一些數據發送到 firebase 並等待良好的回調

  • 在我們從對話框 A 獲得回調后，關閉它並顯示第二個對話框。

聽起來不錯？ 讓我們看看我們如何寫這個：

以下是通用自定義對話框的示例：

這將是你的對話類（或類似的東西，這只是一個例子）：

public class FullSizeImageDialog extends Dialog {
private ImageView imageView;
private ProgressBar fullImageProgreesBar;
private Context dialogContext;

public FullSizeImageDialog(@NonNull Context context) {
    super(context);
    setContentView(R.layout.full_size_image_dialog);
    dialogContext = context;
    imageView = findViewById(R.id.full_size_image);
    fullImageProgreesBar = findViewById(R.id.fullImageProgreesBar);
    }
}

這是你的對話框布局（在我的例子中是R.id.full_size_image ）：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent">


 <!--Place your views here-->


 </android.support.constraint.ConstraintLayout>

當你想顯示你的對話框時，它非常簡單：

FullSizeImageDialog dialog = new FullSizeImageDialog ();
dialog.show();

當第一個對話框從 firebase 獲得回調時，為對話框 A 調用調用dismiss()和為對話框B 調用show() 。

為什么我建議使用這個而不是AlertDialog.Builder ：

  • 您可以使用自定義對話框以更快的方式構建布局。

  • 當您可以擁有自定義布局時，無需編寫大量代碼來添加視圖。

  • 你更容易（或者我相信）看到myCoolDialog.show(); 而不是單個方法中的 50 行或更多代碼。

  • 您需要更改有關對話框外觀和代碼的任何內容嗎？ 好的，轉到您單獨的課程並對其進行更改，而不是在您的活動中再添加 20 行代碼。
