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()

问题 When using an AppBarLayout with the standard ScrollingViewBehavior , the AppBarLayout's sibling will by default be the height of the CoordinatorLayout and the sibling's bottom will be offscreen by the height of the AppBarLayout. In my use case, the NestedScrollView is merely a vehicle to allow for the collapsing of the toolbar, while displaying another scrollable view (fragment in this case) beneath the collapsible toolbar. The fragment is the one who contains the bottom-pinned view (FAB in

问题 I do not know how to explain in words but let the attached picture do the talking ya? Basically, the setError icon is blocking the password toggle icon. Initially I thought it to be a simple layout issue where I had played around with the colors & background, etc. However, so many trial & error yet I can't seem to find the solution to the problem. I'll post my XML here for your reference: <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res

问题 Is there a way to override a color that is already set in your color.xml file? For example - I set the background color on the layout to backgroundColor = "@color/background" The value of background = #000000 Can I override the actual color of background in Java and set the @color/background to say - #FFFFFF? 回答1: It's possible, but rather costly. @color/background is equivalent to R.color.background, where R is your generated class. At runtime, you could use reflection to make the fields
