How can I add a value (setText) to a Material Design TextInputLayout?

How do I setText to a Material Design TextInputLayout (Material Design) in Android Studio?

 //setValue
   BarCode.setText(MainPage.ResultCode.getText());

    TextInputLayout BarCode;

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

        BarCode = findViewById(R.id.barcodeAdd);
        BarCode.setText(MainPage.ResultCode.getText()

The above code did not work for me.

My XML code:

<com.google.android.material.textfield.TextInputLayout
     android:id="@+id/barcodeAdd"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"

     style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox">

      <com.google.android.material.textfield.TextInputEditText
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:hint="Bar Code"/>

</com.google.android.material.textfield.TextInputLayout>

This is the syntax... use it as appropriate in your code:

mTextInputLayout.getEditText().setText("your text");

and

mTextInputLayout.getEditText().getText()
