无法访问AlertDialog中的视图

LayoutInflater inflater = getLayoutInflater();
View dialogView = inflater.inflate(R.layout.custom_dialog_layout, null);

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialogView);

// 获取自定义布局中的视图组件
TextView textView = dialogView.findViewById(R.id.text_view);
Button button = dialogView.findViewById(R.id.button);

// 对视图组件进行操作或设置监听器
textView.setText("Hello World");
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // 处理按钮点击事件
    }
});

AlertDialog alertDialog = builder.create();
alertDialog.show();

public interface AlertDialogListener {
    void onPositiveButtonClick(String inputText);
}

public class MainActivity extends AppCompatActivity implements AlertDialogListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 创建AlertDialog
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Input Dialog");
        builder.setMessage("Please enter your name:");

        // 添加输入框
        final EditText inputEditText = new EditText(this);
        builder.setView(inputEditText);

        // 设置PositiveButton的点击事件
        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                String inputText = inputEditText.getText().toString();
                onPositiveButtonClick(inputText);
            }
        });

        AlertDialog alertDialog = builder.create();
        alertDialog.show();
    }

    @Override
    public void onPositiveButtonClick(String inputText) {
        // 处理PositiveButton点击事件，获取输入框中的文本
        Toast.makeText(this, "Input Text: " + inputText, Toast.LENGTH_SHORT).show();
    }
}
