在地图活动 Android 上创建导航栏

问题描述

我有这个地图活动，我想在其中制作一个导航栏/抽屉。 MapsActivity 中有一个错误说“无法解析方法 setSupportActionBar(android.support.v7.widget.Toolbar)”

地图活动.java

public class MapsActivity extends FragmentActivity implements   
 OnMapReadyCallback {

String [] places= {"bais city","basay","bindoy"};
AutoCompleteTextView textview;

private GoogleMap mMap;
private LatLng latLng;
private Marker marker;

private Toolbar category;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready  
      to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) 
      getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

    category = (Toolbar) findViewById(R.id.Navbar);
    setSupportActionBar(category); //i got my error here says cannot resolve  
     method

}
