android - How to change home as up resource programmatically? -

i know how change homeasupindicator in styles xml file. the question how change programmatically.

the reason want because in views support side navigation (sliding menu) - pressing up/back title button, shows side menu.

in other views support natural up/back botton.

thus different indicator icons indicate 2 different logics - side navigation vs. up/back.

please, lets not argue on motivation of doing this. that's given state. thanks.

int upid = resources.getsystem().getidentifier("up", "id", "android"); if (upid > 0) {     imageview = (imageview) findviewbyid(upid);     up.setimageresource(r.drawable.ic_drawer_indicator); }
