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

Source: Internet

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.

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 );

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.
