android - No padding-effect in custom ImageView -

i've got issue assigning padding-values custom imageview. please note, i'm not extending imageview view:

public class customimageview extends view 

the image loaded assets folder via path. source- , target-rect calculated in onlayout(...) , bitmap assigned in ondraw(...).

good news: image displayed ;-)

bad news: assigning padding-values setpadding(...) has no effect on image (problem solve!). tested "normal" imageview-object , worked desired. unfortunately task extend custom class view, not imageview. if knows how solve - , i'm not first 1 problem ;-) - let me know!

here's ondraw-method, no magic:

@override protected void ondraw(canvas canvas) {     super.ondraw(canvas);      if (bitmap != null)         canvas.drawbitmap(bitmap, sourcerect, targetrect, paint); } 

when setting paddings view, should considered during drawing. can achieve this, creating bitmapdrawable variable in custom view, , initialize , draw according padding, example.

private bitmapdrawable mdrawable;  public void setbitmap(bitmap bitmap) {     mdrawable = new bitmapdrawable(getresources(), bitmap);     invalidate(); }  @override protected void ondraw(canvas canvas) {     super.ondraw(canvas);      if (mdrawable != null) {         int paddingleft = getpaddingleft();         int paddingtop = getpaddingtop();         int paddingright = getpaddingright();         int paddingbottom = getpaddingbottom();          int contentwidth = getwidth() - paddingleft - paddingright;         int contentheight = getheight() - paddingtop - paddingbottom;          mdrawable.setbounds(paddingleft, paddingtop,                 paddingleft + contentwidth, paddingtop + contentheight);         mdrawable.draw(canvas);     } }
