How to get the current context?

I want to use it in my array adapter. When I put this in a sub-activity to create an adapter it does not work.

Answer 1

getApplicationContext() can get the context value

This returns application context, not the current context, both are different. – Canaan

Answer 2

You can get context a few ways:

By the Activity, using Your_Activity_Name.this

By the application, using getApplicationContext()

By the View, using Your_View.getContext()

The only one I would not recommend is using getBaseContext(). If you need something universal, have a public static variable in your main activity and assign the application context to it when your app starts. This way you can always call Your_Activity.your_context_variable

Answer 3

You can use getBaseContext() but this is not a local context.

Answer 4

Besides the correct previous answers, you may want to think about refactoring your code if you've come to the point where you need to access "your" context from a sub activity. When you create a sub activity (ie: startActivityForResult) you are truly waiting for a result, not for an action in the caller activity. Then, when the sub activity has finished (and you have the result of its calculations), you can access your context in a proper way. It just doesn't seem fine that the subactivity is aware of its creator, not to mention interact with it.
