GridLayout. Wie setzen Leerzeichen zwischen den Spalten?

Android Studio 3.1, Java 1.8, Gradle 4.1

Ich verwende GridLayout.
Alle gut funktionieren.
Aber ich brauche, um Speicherplatz (z.B. 10dp) zwischen den Spalten und den Raum zwischen den Zeilen.
Wie kann ich das machen?

main.xml:

            <GridLayout
                android:id="@+id/categoriesContainer"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:verticalSpacing="10dp"
                app:layout_constraintEnd_toEndOf="@+id/birthDateContainer"
                app:layout_constraintStart_toStartOf="@+id/birthDateContainer"
                app:layout_constraintTop_toBottomOf="@+id/birthDateContainer">


            </GridLayout>

profile_category_active.xml

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <android.support.constraint.ConstraintLayout
        android:id="@+id/profileCategoryContainer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">       


        <TextView
            android:id="@+id/categoryNameTextView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="5dp"
            android:layout_marginEnd="30dp"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="30dp"
            android:layout_marginStart="5dp"
            android:layout_marginTop="5dp"
            android:ellipsize="end"
            android:maxLines="1"
            android:text="TextView"                />
    </android.support.constraint.ConstraintLayout>
</layout>

Aktivität: ich Sie Zeile hinzufügen programmatisch:

 GridLayout gridLayout = findViewById(R.id.categoriesContainer);
    gridLayout.setColumnCount(columnCount);
    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    for (int index = 0; index < 10; index++) {
     View profileCategoryActive = inflater.inflate(R.layout.profile_category_active, null, false);
            categoriesGridContainer.addView(profileCategoryActive);
            ConstraintLayout profileCategoryContainer = profileCategoryActive.findViewById(R.id.profileCategoryContainer);
            ViewGroup.LayoutParams profileCategoryContaineParams = profileCategoryContainer.getLayoutParams();
            profileCategoryContaineParams.width = (int) AndroidUtil.dpToPx(this, categoryItemWidth);
            profileCategoryContainer.setLayoutParams(profileCategoryContaineParams);
            TextView categoryNameTextView = profileCategoryActive.findViewById(R.id.categoryNameTextView);
            categoryNameTextView.setText("Ind " + profileCategoryContaineParams.width);
}
