Interface for AppCompatActivity

Question

I want to extend both AppCompatActivity, Fragment activity because I use this code

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

My Java file wants to extend AppCompatActivity but I'm using map in that Activity so it already extends FragmentActivity

Since Java does not not support multiple inheritance, are there any interfaces instead of AppCompatActivity or FragmentActivity I can use?

Answer 1

AppCompatActivity is a subclass of FragmentActivity. So you can use AppCompatActivity in place of FragmentActivity.

If you do not want to use AppCompatActivity, use setActionBar(toolbar) instead of setSupportActionBar(toolbar)
