java - Drawing drawable in canvas doesn't work -


i want draw drawable on canvas code doesn't work , don't know why

getresources().getdrawable(r.drawable.allergist).draw(canvas);

i set custom views heigh , width match parent whole screen white , there no drawable on screen

you need load image bitmap:

 resources res = getresources();  bitmap bitmap = bitmapfactory.decoderesource(res, r.drawable.allergist);

then make bitmap mutable , create canvas on it:

canvas canvas = new canvas(bitmap.copy(bitmap.config.argb_8888, true));

after can draw on canvas.

edit 1

set bounds drawable.

drawable d = getresources().getdrawable(r.drawable.allergist); d.setbounds(left, top, right, bottom); d.draw(canvas);

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
