如何在编程中使TextView居中与ImageView居中对齐？

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/your_image" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Your Text" />
</LinearLayout>

<androidx.constraintlayout.widget.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">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/your_image"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Your Text"
        app:layout_constraintTop_toTopOf="@id/imageView"
        app:layout_constraintBottom_toBottomOf="@id/imageView"
        app:layout_constraintStart_toStartOf="@id/imageView"
        app:layout_constraintEnd_toEndOf="@id/imageView" />
</androidx.constraintlayout.widget.ConstraintLayout>

LinearLayout linearLayout = findViewById(R.id.linearLayout);
linearLayout.setGravity(Gravity.CENTER);

ImageView imageView = findViewById(R.id.imageView);
TextView textView = findViewById(R.id.textView);

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
    LinearLayout.LayoutParams.WRAP_CONTENT,
    LinearLayout.LayoutParams.WRAP_CONTENT
);
layoutParams.gravity = Gravity.CENTER;
imageView.setLayoutParams(layoutParams);
textView.setLayoutParams(layoutParams);
