There is no such thing as a negative margin. Use android:gravity="top" if your textview is higher than your textsize and you want the text to appear on the top. Otherwise use android:layout_height="wrap_content". Your view will exactly fit this way.

If you want 3dp space between the top border of the textview and the actual text, use android:paddingTop="3dp". Generally, margin is the free space outside the view, padding is the inside spacing between the border and the content.
