using findviewbyid in a class that does NOT extend Activity in android

Question

I have a class that is currently extending Activity and I have methods like findViewById, ArrayAdapter etc. I want to turn it into an independent class but all the above met

Answer 1

if you want to call any function that belongs to Activity then only thing you need to have is context of the Activity.

eg.

class A extends Activity {
    Context ctx;

    void onCreate(Bundle b)
        ctx = this;
        B bob = new B(ctx);
    }
}

Here is class B.

class B {

    B (Activity a) {
        a.anyFunctionOfActivity();
    }
}
