public class MapsActivity extends FragmentActivity implements  OnMapReadyCallback {

private GoogleMap mMap;

final Button button1 = (Button) findViewById(R.id.buttonMaps);
final Button button2 = (Button)findViewById(R.id.buttonMaps2);
final Button button3 = (Button)findViewById(R.id.buttonMaps3);

@Override
 protected void onCreate(Bundle savedinstancestate) {
 super.onCreate(savedinstancestate);
setContentView(R.layout.activity_maps);

button1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        mMap.clear();
        if (button1.isShown()) {

            mMap.addMarker(new MarkerOptions().position(new LatLng(, )).title("").snippet("My Location").icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_launcher)));

 {
      @Override
 public void onClick(View v) {

                    mMap.clear();
                    if (button2.isShown()) {

                        mMap.addMarker(new MarkerOptions().position(new LatLng()).title("").icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_launcher_hospital)));
                                                              mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(), ));

                        button3.setOnClickListener(new   View.OnClickListener() {
                            @Override
                            public void onClick(View v) {

                                mMap.clear();
                                if (button3.isShown()) {

                                    mMap.addMarker(new     MarkerOptions().position(new LatLng(`enter code here`)).title("     ").icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_launcher_busstop))   );
                                                          mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(), ));

                                }

                            }

                        });
                    }
                }
            });
        }
    }
});
 }
 // 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);

/**
 * Manipulates the map once available.
  * This callback is triggered when the map is ready to be used.
 * This is where we can add markers or lines, add listeners or move the     camera. In this case,
  * we just add a marker near Sydney, Australia.
 * If Google Play services is not installed on the device, the user will be prompted to install
 * it inside the SupportMapFragment. This method will only be triggered once the user has
 * installed Google Play services and returned to the app.

@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng (               ),));
}
}

Here is my activity_maps.xml

解决问题的最佳方法是使用浮动操作按钮（FAB）。因此，FAB将保持在顶层的地图上。当用户点击FAB时，它将打开更多选项。很少有图书馆这样做。请看下面的选项。
