attr

问题 So jQuery 1.6 has the new function prop(). $(selector).click(function(){ //instead of: this.getAttribute('style'); //do i use: $(this).prop('style'); //or: $(this).attr('style'); }) or in this case do they do the same thing?

问题 I just want to set contentScrim programmatically. So I tried int color = ContextCompat.getColor(getActivity(), R.attr.colorPrimary); collapsingToolbarLayout.setContentScrimColor(color); Then I tried collapsingToolbarLayout.setContentScrimColor( getResources().getColor(R.attr.colorPrimary)); But I keep getting complaints about R.attr.colorPrimary . Any help with this? Someone seems to have ask this question Android - Should pass resolved color instead of resource id here: `getResources()
