SetWidth () Android Button

I created a button placed in a RelativeLayout and I would like to set its size. But I can only set it to a larger size than the original one, for example I can resize it to 200dp but not 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

thank

This is because it Button

has a minimum width by default 64dip

. Set before setting the width 0

.



b.setMinimumWidth(0);
+6

you can set the width of the button by specifying values ​​in the properties window of the xml.on design panel on the right side of the UI design. You can use a small button instead of a button to make it 20dpi.
