Get context directly in PagerAdapter?

Question

I need to use PackageManager pm = context.getPackageManager(); inside a PagerAdapter but I don't know how to get a context.

public class MyPagerAdapter extends PagerAdapter {
     ...
     }

How can context inside PagerAdapter?

Answer 1

The answer of @DeeV means you must provide a context to your PageAdapter by yourself, either via the constructor or via a setter. Then store it inside the PageAdapter as a field and retrieve it whenever you need it.

Answer 2

private ViewGroup _container;

public override Java.Lang.Object InstantiateItem(ViewGroup container, int position)
{
   _container = container;
}

private Context GetContext()
{
   return (Activity)_container.Context;
}

Answer 3

It's not recommended provide Context, this may cause memory leaks, if you need the context to access resources, you can provide the resources through the constructor.

MyPagerAdapter(val resources: Resources){

}
....

val adapter = MyPagerAdapter(context.resources)
