[Difficult for Android] The problem of dynamic change of the Padding after the Background is invalid

Preface

After the background and padding are specified in Layout, the dynamic modification of the background in the program will render the padding invalid. It seems to be a BUG. Here I found an English article to share it with you.

I. Compromise

1.1 method 1

Int bottom = theView. getPaddingBottom ();
Int top = theView. getPaddingTop ();
Int right = theView. getPaddingRight ();
Int left = theView. getPaddingLeft ();
TheView. setBackgroundResource (R. drawable. entry_bg_with_image );
TheView. setPadding (left, top, right, bottom );

1.2 method 2

Int pad = resources. getDimensionPixelSize (R. dimen. linear_layout_padding );
TheView. setBackgroundResource (R. drawable. entry_bg_with_image );
TheView. setPadding (pad, pad );

Code Description:

In fact, it is to reset the padding after setBackgroundResource.

3. Search for keywords

GOOGLE: "android setbackgroundresource changes padding"

Search engines can basically solve 99% of my problems. Chinese keywords cannot be changed to English keywords, or you can directly search for code. Beginners should regard search as their most important learning tool as soon as possible, I will try my best to add search keywords to similar articles in the future.
