How can i keep the borders on a view while changing dynamically its background color?

Question

I applied borders on a linear layout:

<LinearLayout
        android:id="@+id/lay1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="80"
        android:background="@drawable/linearborder2" />

and in my main activity i want to change dynamically the background color of this one, but i do that the borders fade away. So how can i do to keep these borders and change the color?

Thank you

how to do that ? in my main activity i wrote vi.setBackgroundColor(color) color is the new color chosen — user2137817, Mar 06 '13 at 10:54
You should create another drawable.. Just like "linearborder2" — ngesh, Mar 06 '13 at 10:56
linearborder2 is a xml file, how can i put a dynamic variable (which is the color) in a xml file? — user2137817, Mar 06 '13 at 10:59

Assuming linearborder2 is a shape drawable.You can change the color of a shape drawable dynamically. This should help with that.

i tried this one:GradientDrawable sd = (GradientDrawable) tv2.getBackground().mutate(); sd.setColor(color); sd.invalidateSelf(); & this one i found on the post you gave me ShapeDrawable bgShape = (ShapeDrawable )btn.getBackground(); bgShape.getPaint().setColor(Color); but i got a null exception pointer on both – user2137817 Mar 06 '13 at 11:22
