Set layout_column and layout_row in GridLayout programmatically

I have a GridLayout (not GridView) where I want to add some views with a special row and column inex. In XML I can set the View with:

<TextView
    android:id="@+id/textView1"
    android:layout_column="2"
    android:layout_row="4"
    android:text="Large Text" />

But how can I set the attributes layout_column and layout_row programmatically? I want something like this:

GridLayout grid = new GridLayout(getActivity());

grid.setColumn(2);
grid.setRow(4);

grid.addView(new Button(getActivity());
