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'

Solution 1

Use

getActivity().getApplicationContext()

instead of

this

Solution 2

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)

Solution 3

Use :

actionBar.setBackgroundColor(ContextCompat.getColor(getApplicationContext(), 

R.color.action_bar));

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.

A Fragment is not a Context

No than Android studio say : cannot resolve symbol: 'getActivity()'

[Yannick - theSpy_007]

Same like above. Android Studio say: Cannot resolve symbol: 'getContext()'

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 stackoverflow.com/questions/8215308/using-context-in-a-fragm‌​ent
