如何解决如何通过 Intent 移动到下一个活动？

我正在尝试制作一个银行应用程序并且我正在尝试制作一个成功活动，当我尝试从 MainActivity.java 移动到 successActivity.java 时，我得到了一个空白页面。

这是我的 MainActivity.java：

package com.example.bankapp.ui;


import androID.content.Intent;
import androID.os.bundle;
import androID.vIEw.VIEw;
import androID.Widget.EditText;
import androID.Widget.RadioGroup;
import androID.Widget.Toast;

import androIDx.Annotation.Nullable;
import androIDx.appcompat.app.AppCompatActivity;

import com.example.bankapp.R;
import com.example.bankapp.data.AccountRepository;
import com.example.bankapp.databinding.ActivitymainBinding;
import com.example.bankapp.domain.bankAccount;
import com.example.bankapp.domain.successpayment;

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;
import java.util.UUID;

public class MainActivity extends AppCompatActivity {

    private ActivitymainBinding binding;
    private BankAccount bankAccount;

    @OverrIDe
    protected voID onCreate(@Nullable Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        bankAccount = new AccountRepository().getAccount();
        binding = ActivitymainBinding.inflate(getLayoutInflater());
        setContentVIEw(binding.getRoot());
        bindBankDataToRadiobuttons(bankAccount);
        bindBankDataToVIEws(bankAccount);
        binding.rbGroup.setoncheckedchangelistener(new RadioGroup.oncheckedchangelistener() {
            @OverrIDe
            public voID oncheckedChanged(RadioGroup group,int checkedID) {
                binding.bnpagar.setEnabled(true);
                if (checkedID == R.ID.rbotraCantIDad) {
                    binding.etnuevaCantIDad.setVisibility(VIEw.VISIBLE);
                    binding.ingreseCantIDad.setVisibility(VIEw.VISIBLE);
                } else {
                    binding.etnuevaCantIDad.setVisibility(VIEw.GONE);
                    binding.ingreseCantIDad.setVisibility(VIEw.GONE);
                }
            }
        });

        binding.bnpagar.setonClickListener(new VIEw.onClickListener() {
            @OverrIDe
            public voID onClick(VIEw v) {
                double amounttopay = getamounttopay();
                if (amounttopay == -1.0) {
                    showToastmessage(getString(R.String.err_cantIDadIncorrecta));
                } else if (amounttopay <= bankAccount.getAccountBalance()) {
                    successpayment successpayment = makePayment(amounttopay,bankAccount);
                    Intent intent = new Intent(getApplicationContext(),successActivity.class);
                    intent.putExtra("succesS_EXTRA",successpayment);
                    startActivity(intent);
                    finish();

                } else {
                    showToastmessage(getString(R.String.err_saldoInsuficIEntE));
                }
            }
        });
    }




    private double getamounttopay() {
        double amount;
        switch (binding.rbGroup.getcheckedRadiobuttonID()) {
            case R.ID.rbdeudaActual:
                amount = bankAccount.getCurrentDebt();
                break;
            case R.ID.rbsinInteres:
                amount = bankAccount.getMinimumPaymentDue();
                break;
            case R.ID.rbpagoMinimo:

            default:
                amount = getamountFromEditText(binding.etnuevaCantIDad);
        }
        return amount;
    }

    private double getamountFromEditText(EditText editText) {
        try {
            String text = editText.getText().toString();
            return Double.parseDouble(text);
        } catch (numberFormatException E) {
            return -1.0;
        }
    }

    private voID bindBankDataToRadiobuttons(BankAccount bankAccount) {
        binding.rbdeudaActual.setText(
                getString(R.String.label_deudaActual,bankAccount.getCurrentDebt())
        );
        binding.rbsinInteres.setText(
                getString(R.String.label_sinInteres,bankAccount.getMinimumPaymentDue())
        );
        binding.rbpagoMinimo.setText(
                getString(R.String.label_pagoMinimo,bankAccount.getPaymentDue())
        );
    }

    private voID bindBankDataToVIEws(BankAccount bankAccount) {
        binding.cardlayout.tvAccountname.setText(bankAccount.getAccountname());
        //El String label_peso_sign pIDe un número,por eso el método getString recibe
        //un segundo parámetro,que en este caso es el accountBalance.
        binding.cardlayout.tvAccountBalance.setText(getString(R.String.label_peso_sign,bankAccount.getAccountBalance()));
        binding.cardlayout.tvAccountnumber.setText(bankAccount.getAccountnumber());
        binding.cardlayout.tvCardname.setText(bankAccount.getCardname());
        binding.cardlayout.tvCardnumber.setText(bankAccount.getCardnumber());
        binding.cardlayout.tvCurrentDebtamount.setText(getString(R.String.label_peso_sign,bankAccount.getCurrentDebt()));
        binding.cardlayout.tvClosingDateBalanceamount.setText(getString(R.String.label_peso_sign,bankAccount.getClosingDateBalance()));
        binding.cardlayout.tvPaymentDate.setText(bankAccount.getPaymentDueDate());
    }


    private voID showToastmessage(String messagE) {
        Toast.makeText(this,message,Toast.LENGTH_SHORT).show();
    }

    private successpayment makePayment(double amount,BankAccount bankAccount) {
        String date = new SimpleDateFormat(
                "dd 'de' MMMM 'de' yyyy",new Locale("es","MX")
        ).format(new Date(Calendar.geTinstance().getTimeInMillis()));
        String referencenumber = UUID.randomUUID().toString().subString(0,10);
        // amount -> double
        // date -> String
        // referencenumber -> String
        // bankAccount -> BankAccount
        return new successpayment(
                amount,date,referencenumber,bankAccount
        );
    }


}

这是我的 Activity_main.xml：

</linearLayout>

这是我的成功Activity.java：

package com.example.bankapp.ui;

import androID.os.bundle;
import androIDx.Annotation.Nullable;
import androIDx.appcompat.app.AppCompatActivity;

import com.example.bankapp.R;
import com.example.bankapp.databinding.ActivitysuccessBinding;
import com.example.bankapp.domain.successpayment;


public class successActivity extends AppCompatActivity {

    private ActivitysuccessBinding binding;



    @OverrIDe
    protected voID onCreate(@Nullable Bundle savedInstanceStatE) {
        binding = ActivitysuccessBinding.inflate(getLayoutInflater());
        setContentVIEw(binding.getRoot());
        super.onCreate(savedInstanceStatE);
        setContentVIEw(R.layout.activity_success);
        successpayment payment = geTintent().getParcelableExtra("succesS_EXTRA");
    }
}

这是我的 Activitysuccess.xml :

<?xml version="1.0" enCoding="utf-8"?>
<linearLayout xmlns:androID="http://scheR_786_11845@as.androID.com/apk/res/androID"
    xmlns:app="http://scheR_786_11845@as.androID.com/apk/res-auto"

    androID:layout_wIDth="match_parent"
    androID:layout_height="match_parent"
    androID:orIEntation="vertical">

        androID:ID="@+ID/imageVIEw2"
        androID:layout_wIDth="match_parent"
        androID:layout_height="match_parent"
        androID:contentDescription="@String/label_current_debt"
        tools:srcCompat="@tools:sample/avatars" />
</linearLayout>

这是我的 AndroID 清单：

<?xml version="1.0" enCoding="utf-8"?>
<manifest xmlns:androID="http://scheR_786_11845@as.androID.com/apk/res/androID"
    package="com.example.bankapp">

    <application
        androID:allowBACkup="true"
        androID:icon="@mipmap/ic_launcher"
        androID:label="@String/app_name"
        androID:rounDicon="@mipmap/ic_launcher_round"
        androID:supportsRtl="true"
        androID:theme="@style/theme.bankApp">

        <activity androID:name=".ui.MainActivity">
            <intent-filter>
                <action androID:name="androID.intent.action.MAIN" />
                <category androID:name="androID.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity androID:name=".ui.successActivity" > </activity>




</application>

</manifest>

解决方法

@Override
protected void onCreate(@Nullable Bundle savedInstanceStatE) {
     super.onCreate(savedInstanceStatE);        

    binding = ActivitysuccessBinding.inflate(getLayoutInflater());
    setContentView(binding.getRoot());
    setContentView(R.layout.activity_success);
    successPayment payment = geTintent().getParcelableExtra("succesS_EXTRA");
}
