我有一个FragmentActivity，我想在其中使用一个地图片段。我有一个问题，让支持片段管理器访问它。
if (googleMap == null) {
googleMap = ((SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map1)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
// create marker
MarkerOptions marker = new MarkerOptions().position(
new LatLng(latitude, longitude)).title("Hello Maps ");
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(latitude, longitude)).zoom(15).build();
googleMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
// adding marker
googleMap.addMarker(marker);
