Your activity is probably already available in your View via getContext().
If not, adjust your custom View's constructor to take an Activity as the
first parameter, and hold onto that Activity in your View:
public class MyCustomView extends View {
private Activity momma;
MyCustomView(Activity momma) { // and possibly other parameters
super(momma); // View requires a Context; Activity is a Context
this.momma=momma;
// other stuff here
}
}
