    LatLng cenpt=new LatLng(lat,lon);
    MapStatus mMapStatus=new MapStatus.Builder().target(cenpt)
            .zoom(17)
            .build();
    // Definition MapStatusUpdate object , To describe the changes that will take place in the map state 
    MapStatusUpdate mMapStatusUpdate = MapStatusUpdateFactory.newMapStatus(mMapStatus);
    // Change the map state 
    mBaiduMap.setMapStatus(mMapStatusUpdate);
    BitmapDescriptor bitmap= BitmapDescriptorFactory.fromResource(R.mipmap.ic_location);
    OverlayOptions option = new MarkerOptions()
            .position(cenpt)
            .icon(bitmap);
    mBaiduMap.addOverlay(option);
}
