Can you tell me how?

Answer 1

Try this:

public class SettingsActivity extends AppCompatPreferenceActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        LinearLayout root = (LinearLayout) findViewById(android.R.id.list).getParent().getParent().getParent();
        Toolbar toolbar = (Toolbar) LayoutInflater.from(this).inflate(R.layout.toolbar_settings, root, false);
        root.addView(toolbar, 0);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }
}

EDIT

AppCompatPreferenceActivity is this demo class for supprt v7:
