Null pointer exception error occure at map.setMapType(GoogleMap.MAP_TYPE_SATELLITE).

You need to add MapFragment Dynamically when you want to inflate a MapFragment inside a Fragment.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.main_map, container, false);
SupportMapFragmentmf = SupportMapFragment.newInstance();
FragmentManager fm = getChildFragmentManager();
fm.beginTransaction().replace(R.id.mapView, mf, "normal_map").commit();
mf.getMapAsync(new OnMapReadyCallback() {
#Override
public void onMapReady(GoogleMap arg0) {
map = arg0;
map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
}
});
return view;
}
where your main_map should be like below
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mapView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
I hope that helps. Please let me know if you have any doubts.
you should use
getMapAsync(OnMapReadyCallback callback)
then in the callback you can set the map to satellite view

Trying to add Fragment to my Activity, but it isn't showing up.
public class MainActivity extends AppCompatActivity {
private static final String TAG = MainActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WeatherFragment mainFragment = new WeatherFragment();
getFragmentManager()
.beginTransaction()
.add(R.id.main_weather_container, mainFragment)
.commit();
}
}
And there is my fragment:
public class WeatherFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
boolean isAttachedToParent = false;
View inflatedView = inflater.inflate(R.layout.main_weather_fragment, container, isAttachedToParent);
return inflatedView;
}
}
R.id.main_weather_container - FrameLayout in my MainActivity.
R.layout.main_weather_fragment - Fragment's layout
What am i doing wrong?
I've tried to use FragmentActivity + v4 support fragment and fragmentSupportManager, but it didn't make any difference.
MainActivity xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout
android:id="#+id/main_weather_container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:padding="#dimen/padding_16_dp" />
<android.support.v7.widget.RecyclerView
android:id="#+id/words_recycler_view"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="3" />
</LinearLayout>
UPDATED: The problem wasn't in fragment transaction or whatever, i've used tools: namespace that's why fragment wasn't displayed. Sorry about that :(
try this way .in your activity call fragment
Fragment fragment = Video_fragment.newInstance();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.framecontainer, fragment).commit();
in fragment class.
public class Video_fragment extends Fragment{
View view;
public static Fragment newInstance() {
Video_fragment fragment = new Video_fragment();
return fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
view= inflater.inflate(R.layout.video_frag, container, false);
return view;
}
}
Create a instance of Fragment in WeatherFragment:
public static WeatherFragment newInstance() {
Bundle args = new Bundle();
WeatherFragment weatherFragment = new WeatherFragment();
weatherFragment.setArguments(args);
return weatherFragment;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_layout, container, false);
}
Inside your Activity in MainActivity :
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WeatherFragment weatherFragment = WeatherFragment.newInstance();
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.flContainerId, weatherFragment)
.commit();
}
Your layout file will be:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/flContainerId"/>
public class WeatherFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View inflatedView = inflater.inflate(R.layout.main_weather_fragment, null, false);
return inflatedView;
}
}
As I can see, you are using AppCompatActivity but using getFragmentManager.
With AppCompatActivity you will need to use getSupportFragmentManager() rather than getFragmentManager()
public class MainActivity extends AppCompatActivity {
private static final String TAG = MainActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WeatherFragment mainFragment = new WeatherFragment();
getSupportFragmentManager()
.beginTransaction()
.add(R.id.main_weather_container, mainFragment)
.commit();
}
}
Your WeatherFragment should be extend android.support.v4.app.Fragment;
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="4"
android:orientation="vertical">
<FrameLayout
android:id="#+id/main_weather_container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:padding="#dimen/padding_16_dp" />
<android.support.v7.widget.RecyclerView
android:id="#+id/words_recycler_view"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="3" />
</LinearLayout>
Added WeightSum in the parent Layout.
Excuse me for any grammatical errors.
I followed a tutorial to view the google map in a fragment, but something has gone wrong.
this is my file .java that is hooked with the fragment:
public class MapFragment extends Fragment implements OnMapReadyCallback{
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_map, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
MapFragment fragment = (MapFragment)getChildFragmentManager().findFragmentById(R.id.map);
fragment.getMapAsync(this); //Here i get the error
}
#Override
public void onMapReady(GoogleMap googleMap) {
}
}
This is the layout fragment:
<fragment
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment"></fragment>
What did I do wrong?
Thank you!
You have to use SupportMapFragment rather than MapFragment
in XML
<fragment
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"></fragment>
in Fragment
SupportMapFragment fragment = (SupportMapFragment)getChildFragmentManager().findFragmentById(R.id.map);
fragment.getMapAsync(this);
i Have a Fragment that should show a Specific place on Google Map
public class ContactFragment extends Fragment implements OnMapReadyCallback {
public ContactFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
FragmentManager fragment = getActivity().getSupportFragmentManager();
final SupportMapFragment myMAPF = (SupportMapFragment) fragment.findFragmentById(R.id.map);
return inflater.inflate(R.layout.fragment_contact, container, false);
}
#Override
public void onMapReady(GoogleMap googleMap) {
LatLng marker = new LatLng(34.877737,-1.326545);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(marker,13));
googleMap.addMarker(new MarkerOptions().position(marker));
}
}
and in the XML file of the Fragment i have this :
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/map"
android:layout_below="#+id/contact_domiciliation"
class="com.google.android.gms.maps.MapFragment"
></fragment>
Yet when i launch click on the button that opens this fragment i get a map of the entire globe .
Add this line of code to the fragment:
myMAPF.getMapAsync(this);
I have a class to create a fragment containing a map, but the following error is occurring:
Error inflating class fragment
My LayoutMap.axml file:
`<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
class="com.google.android.gms.maps.MapFragment" />`
My Activity_TabMap:
public override void OnActivityCreated(Bundle saveInstanceState)
{
base.OnActivityCreated (saveInstanceState);
_mapaFragment = SupportMapFragment.NewInstance ();
GoogleMap googleMap = ((SupportMapFragment)(FragmentManager.FindFragmentById (Resource.Id.map))).Map;
googleMap.MapType = GoogleMap.MapTypeNormal;
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
return inflater.Inflate (Resource.Layout.LayoutMap, container, false);
}
Good night,
I have an application with a map in a swipe tab, but I want that map select a point and start at that point.
Thank you in advance.
Enclose JAVA:
public class Mapa extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View android = inflater.inflate(R.layout.mapa_3, container, false);
return android;
}
#Override
public void onDestroyView() {
super.onDestroyView();
Fragment f = getFragmentManager().findFragmentById(R.id.mapFragment);
if (f != null)
getFragmentManager().beginTransaction().remove(f).commit();
}
}
the layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/map_container"
tools:context=".Mapa" >
<fragment
android:id="#+id/mapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
</RelativeLayout>
I guess you want to add a marker to a map and set camera to look at it. Here is how you can achieve it(more info here and here):
GoogleMap map;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View android = inflater.inflate(R.layout.mapa_3, container, false);
final LatLng position = new LatLng(MARKER_LATITUDE, MARKER_LONGITUDE);
// marker
map = ((MapFragment) getSupportFragmentManager().findFragmentById(R.id.mapFragment)).getMap();
map.addMarker(new MarkerOptions()
.position(position)
.title("Hello world"));
// camera position
map.setOnCameraChangeListener(new OnCameraChangeListener()
{
#Override
public void onCameraChange(CameraPosition arg0)
{
CameraUpdate cu = CameraUpdateFactory.newLatLngZoom(position, 14);
map.animateCamera(cu);
map.setOnCameraChangeListener(null);
}
});
return android;
}
