如何从android自定义对话框中的视图字段获取数据

<!-- res/layout/custom_dialog.xml -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="16dp">

    <EditText
        android:id="@+id/editTextName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Enter your name" />

    <Button
        android:id="@+id/buttonSubmit"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Submit" />
</LinearLayout>

public void showCustomDialog() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    LayoutInflater inflater = getLayoutInflater();
    View dialogView = inflater.inflate(R.layout.custom_dialog, null);
    builder.setView(dialogView);

    final EditText editTextName = dialogView.findViewById(R.id.editTextName);
    Button buttonSubmit = dialogView.findViewById(R.id.buttonSubmit);

    final AlertDialog alertDialog = builder.create();

    buttonSubmit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String name = editTextName.getText().toString();
            // 处理获取到的数据
            Toast.makeText(MainActivity.this, "Name: " + name, Toast.LENGTH_SHORT).show();
            alertDialog.dismiss();
        }
    });

    alertDialog.show();
}
