setWidth() Button Android

Question

I've created a Button placed in a RelativeLayout and I'd like to set its size. But I can only set a larger size that the original one, for example I can resize it to 200dp but no to 20dp.

Is there a solution ?

Here is my code

Button b = new Button(getApplicationContext());
myLayout.addView(b);
b.setWidth(200); // Work
b.setWidth(20); // Don't work

Thanks

That is because the Button has a minimum width of 64dip by default. Set it to 0 before setting the width.

b.setMinimumWidth(0);
