Argument this doesn´t work. [required: 'android.content.context'

Question

I use this:

actionBar.setBackgroundColor(ContextCompat.getColor(this, R.color.action_bar));

To use colors from the color.xml .

It works great, but in some Codes it says:

Wrong 1st argument type. Found: 'org.telegram.ui.ActionBar.BaseFragment', required: 'android.content.Context'

But I import android.content.Context:

import android.content.Context;

I tried to use instead of 'this':

actionBar.setBackgroundColor(ContextCompat.getColor(context, R.color.action_bar));

But than Android Studio say :

Cannot resolve symbol 'context'

When you're in a fragment you cannot pass `this` for it's a Fragment, not an Activity and thus not a subtype of `Context`. Use `getContext()` instead. — m02ph3u5, Mar 05 '16 at 16:27

instead of

this

Fragment is not a subtype of Context.

When inside of a fragment use this:

ContextCompat.getColor(getContext(), R.color.action_bar)

When inside an activity you can use:

ContextCompat.getColor(this, R.color.action_bar)

Same like above. Android Studio say: Cannot resolve symbol: 'getContext()' – Yannick - theSpy_007 Mar 05 '16 at 16:37
What's `org.telegram.ui.ActionBar.BaseFragment`? If it's a subclass of androids `Fragment` and you haven't messed with `getContext()` or `getActivity()` either should work. Also see http://stackoverflow.com/questions/8215308/using-context-in-a-fragment – m02ph3u5 Mar 06 '16 at 14:59

R.color.action_bar));
