what is equivalent of stretchableImageWithLeftCapWidth (iOS) for Android?

Question

is there any method, property or xml tag for Android to stretch image like iOS?

for example:

UIImage *stretchableBackButton = [[UIImage imageNamed:@"back.png"] stretchableImageWithLeftCapWidth:6 topCapHeight:6];
[button setBackgroundImage:stretchableBackButton forState:UIControlStateNormal];

it stretches the image from 6 px to whole width/height.

thanks...

ok, i found it. it is Nine patch. there is no method or any xml tag. image file must be redrawn by draw9patch tool.

You can do this code in xml imageView

android:scaleType="fitCenter" android:adjustViewBounds="true"

or you can use through program like this

imageview.setAdjustViewBounds(true);
imageview.setScaleType(ScaleType.FIT_XY);
