Is it possible to show a map view inside a dialog fragment?

Is it possible to show a map view inside a dialog fragment? - android

I have a dialog fragment where i want to show my map and mark the lat and log which i have with with me.
But i am getting my getMap() as NULL. This is what i did
public class EventDetailsDialogFragment extends DialogFragment{
TextView title, desc, sdate, edate, room, loctn;
FeedObjModel selectedFeedObject;
Date netDate;
SimpleDateFormat sdf;
GoogleMap theMap;
MarkerOptions markerOptions;
FragmentActivity myContext;
#Override
public void onAttach(Activity activity) {
// TODO Auto-generated method stub
super.onAttach(activity);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.event_details_dialog_layout, container);
title = (TextView) view.findViewById(R.id.title_event_details_TV);
desc = (TextView) view.findViewById(R.id.description_event_details_TV);
sdate = (TextView) view.findViewById(R.id.start_date_event_details_TV);
edate = (TextView) view.findViewById(R.id.end_date_event_details_TV);
loctn = (TextView) view.findViewById(R.id.locEdTV);
long timestamp1 = Long.parseLong(selectedFeedObject.eventstartDate);
long timestamp2 = Long.parseLong(selectedFeedObject.eventendDate);
try{
sdf = new SimpleDateFormat("MMM dd, yyyy");
netDate = (new Date(timestamp1*1000));
sdate.setText(sdf.format(netDate));
netDate = (new Date(timestamp2*1000));
edate.setText(sdf.format(netDate));
} catch(Exception ex){
}
getDialog().setTitle(""+selectedFeedObject.subject);
title.setText(selectedFeedObject.subject);
desc.setText(selectedFeedObject.eventDescription);
loctn.setText(selectedFeedObject.eventLocation);
/* theMap = ((SupportMapFragment) getActivity().getSupportFragmentManager()
.findFragmentById(R.id.mapED))
.getMap();*/
SupportMapFragment fragment = new SupportMapFragment();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.mapED, fragment).commit();
theMap = fragment.getMap();
Log.v("theMap1", ""+theMap);
Double lng = Double.parseDouble(selectedFeedObject.eventlongitude);
Double lat = Double.parseDouble(selectedFeedObject.eventlatitude);
LatLng latLng = new LatLng(lng, lat);
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title(selectedFeedObject.eventLocation);
Log.v("markerOptions", ""+markerOptions);
theMap.addMarker(markerOptions);
theMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
CameraUpdate center = CameraUpdateFactory
.newLatLng(new LatLng(lat, lng));
CameraUpdate zoom = CameraUpdateFactory.zoomTo(15);
theMap.moveCamera(center);
theMap.animateCamera(zoom);
return view;
}
public void setEventDetails(FeedObjModel _selectedFeedObject) {
// TODO Auto-generated method stub
selectedFeedObject = _selectedFeedObject;
}
}
i am getting 'themap' as NULL

I wrote the following code in onResume() now this is working...i don't know is this the right way.
#Override
public void onResume() {
// TODO Auto-generated method stub
super.onResume();
theMap = mapView.getMap();
Log.v("theMap1", ""+theMap);
Log.v("lng", ""+lng);
Log.v("lat", ""+lat);
latLng = new LatLng(lng, lat);
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title(locString);
Log.v("markerOptions", ""+markerOptions);
theMap.addMarker(markerOptions);
theMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
CameraUpdate center=
CameraUpdateFactory.newLatLngZoom(new LatLng(lat,
lng),16);
CameraUpdate zoom = CameraUpdateFactory.zoomTo(15);
theMap.moveCamera(center);
theMap.animateCamera(zoom);
}
in oncreateview
mapView = CustomMapFragmentForEventDetails.newInstance();
FragmentTransaction fragmentTransaction = getChildFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.mapED, mapView);
fragmentTransaction.commit();
lng = Double.parseDouble(selectedFeedObject.eventlongitude);
lat = Double.parseDouble(selectedFeedObject.eventlatitude);
and in CustomMapFragmentForEventDetails
public class CustomMapFragmentForEventDetails extends SupportMapFragment {
SupportMapFragment mSupportMapFragment;
GoogleMap googleMap;
OnMapReadyListener mOnMapReadyListener;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
super.onCreateView(inflater, container, savedInstanceState);
Log.v("Inside CustomMapFrag", "Success");
View root = inflater.inflate(R.layout.event_details_dialog_layout, null, false);
initilizeMap();
return root;
}
#Override
public void onAttach(Activity activity) {
// TODO Auto-generated method stub
super.onAttach(activity);
mOnMapReadyListener = (OnMapReadyListener) activity;
}
private void initilizeMap()
{
mSupportMapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.mapED);
if (mSupportMapFragment == null) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
mSupportMapFragment = SupportMapFragment.newInstance();
fragmentTransaction.replace(R.id.mapED, mSupportMapFragment).commit();
}
if (mSupportMapFragment != null)
{
googleMap = mSupportMapFragment.getMap();
if (googleMap != null)
{
Log.v("MAP GOOGLE in CustomMApfragment", ":: "+googleMap);
mOnMapReadyListener.onMapReady(googleMap);
}
}
}
public static interface OnMapReadyListener {
void onMapReady(GoogleMap googleMap);
}
}

I guess this is because even thought the Transaction of the map fragment is committed it does not execute immediately. You have to use : FragmentManager.executePendingTransactions() this way :
SupportMapFragment fragment = new SupportMapFragment();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.mapED, fragment).commit();
getFragmentManager().executePendingTransactions();
theMap = fragment.getMap();

How can I set the map view to full screen with bottom navigation bar

I want to set the mapview to full screen, I had done every necessary things like setting both the framelayout and the mapview to matchparent but still when i run the app on my phone only a portion(maybe 60dp is the height but the width is fullscreen) of map was visible.
Here are some of my layout xml file.

Use FrameLayout Instead of Scrollview for "fragment_container"

Add Marker to Google Map in SupportFragment

I did a tabbed-activity with for tabs. In the fourth tab I did a map, and I added a marker but the marker is not visible and I do not undertand why. I tried many solutions for my problem, but for now I have come to this situation.
This is my Java code:
public class tab_mappa extends SupportMapFragment implements OnMapReadyCallback {
private GoogleMap googleMap;
SupportMapFragment mSupportMapFragment;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
super.onCreateView(inflater, container, savedInstanceState);
View root = inflater.inflate(R.layout.tabmappa, null, false);
mSupportMapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.map);
if (mSupportMapFragment == null) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
mSupportMapFragment = SupportMapFragment.newInstance();
fragmentTransaction.replace(R.id.map, mSupportMapFragment).commit();
}
return root;
}
#Override
public void onMapReady(final GoogleMap googleMap) {
this.googleMap = googleMap;
this.googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
this.googleMap.getUiSettings().setZoomControlsEnabled(true);
this.googleMap.getUiSettings().setCompassEnabled(true);
this.googleMap.getUiSettings().setMyLocationButtonEnabled(true);
this.googleMap.getUiSettings().setZoomGesturesEnabled(true);
this.googleMap.getUiSettings().setRotateGesturesEnabled(true);
LatLng pos1 = new LatLng(44.783878,10.879663);
final LatLngBounds.Builder builder = new LatLngBounds.Builder();
builder.include(pos1);
this.googleMap.addMarker(new MarkerOptions().position(pos1));
this.googleMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
#Override
public void onMapLoaded() {
googleMap.moveCamera(CameraUpdateFactory.newLatLngBounds(builder.build(), 100));
}
});
}
#Override
public void onPause() {
super.onPause();
}
#Override
public void onResume() {
super.onResume();
setUpMapIfNeeded();
}
private void setUpMapIfNeeded() {
if (googleMap == null) {
getMapAsync(this);
}
}
}
This is my xml code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tools="http://schemas.android.com/tools"
android:gravity="center"
android:orientation="vertical"
tools:context="esame.progetto.xhondar.github.com.info.tab_mappa">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1.03"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map" />
</LinearLayout>
And this is my final result:
Do you have any ideas?

I solved the problem, this is the solution for those who need it:
Java code:
import android.support.v4.app.Fragment;
public class tab_mappa extends Fragment implements OnMapReadyCallback {
GoogleMap map;
SupportMapFragment mapFragment;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.tabmappa, container, false);
SupportMapFragment mapFragment = (SupportMapFragment) this.getChildFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
return v;
}
#Override
public void onMapReady(GoogleMap googleMap){
map = googleMap;
this.map = googleMap;
this.map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
this.map.getUiSettings().setZoomControlsEnabled(true);
this.map.getUiSettings().setCompassEnabled(true);
this.map.getUiSettings().setMyLocationButtonEnabled(true);
this.map.getUiSettings().setZoomGesturesEnabled(true);
this.map.getUiSettings().setRotateGesturesEnabled(true);
LatLng pp = new LatLng(44.783878,10.879663);
map.addMarker(new MarkerOptions().position(pp).title("Carpi"));
map.animateCamera(CameraUpdateFactory.newLatLngZoom(pp, 8));
}
}
Xml code:
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="esame.progetto.xhondar.github.com.info.tab"/>
The error was located in xml code: is Fragment and not FrameLayout, this thing brought conflict within the code.

How about use marker without the builder? you wrote the code in onMapReady()
LatLng pos1 = new LatLng(44.783878,10.879663);
final LatLngBounds.Builder builder = new LatLngBounds.Builder();
builder.include(pos1);
this.googleMap.addMarker(new MarkerOptions().position(pos1));
this.googleMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
#Override
public void onMapLoaded() {
googleMap.moveCamera(CameraUpdateFactory.newLatLngBounds(builder.build(), 100));
}
});
it change to
LatLng pos1 = new LatLng(44.783878,10.879663);
googleMap.addMarker(new MarkerOptions().position(pos1));
this.googleMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
#Override
public void onMapLoaded() {
googleMap.moveCamera(CameraUpdateFactory.newLatLngBounds(builder.build(), 100));
}
});
this one. I removed builder and this before googleMap.

How can inflate view personalized addmarker? gmaps

The other day I asked, as fill from a cursor. I got on top of that focus all brands with the maximum zoom.
But now I have a problem and fill in the custom view, where there is title, description, and latitude and longitude.
It takes me head, I'm trying to look as filling sight, but each does so in a way. I am not able.
Here my code

Error inflating class fragment, when a map fragment is added to activity

I am able to open the map fragment for the first time when I click on the Action bar icon, search for a location, add a marker at the location and add the location name to the list view on clicking the marker. But when I click on the action bar icon again to search for another place my app crashes. Please help, I have gone through other similar questions on So but nothing worked. Thanks in advance.

onResume Method in Fragment is not working

In my application I am using navigation drawer to move from one fragment to another.
If I move from about_us fragment to another then if I again comeback to same the activity is not getting resumed, instead the application is getting closed unfortunately.
Can anyone tell me what is the problem in my code, pls tell me the solution to fix this.
public class AboutUsFragment extends Fragment {
public AboutUsFragment(){}
private GoogleMap gmap;
static final double latitude = 33.12615;
static final double longitude = 80.21932;
TextView aboutUs;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_about_us, container, false);
initilizeMap();
return rootView;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
View aboutUs = getActivity().findViewById(R.id.about_us_content_view);
try {
// Loading map
initilizeMap();
//To enable compass
gmap.getUiSettings().setCompassEnabled(true);
//To locate the school - Creating Marker
MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("School Location");
// adding marker
gmap.addMarker(marker);
//We assigned latitude and longitude in Coordinate
LatLng coordinate = new LatLng(latitude, longitude);
CameraUpdate schoolLocation = CameraUpdateFactory.newLatLngZoom(coordinate, 5);
gmap.animateCamera(schoolLocation);
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(coordinate) // Sets the center of the map to Mountain View
.zoom(17) // Sets the zoom
.bearing(90) // Sets the orientation of the camera to east
.tilt(30) // Sets the tilt of the camera to 30 degrees
.build(); // Creates a CameraPosition from the builder
gmap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
} catch (Exception e) {
e.printStackTrace();
}
}
private void initilizeMap()
{
if (gmap == null) {
gmap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
// check if map is created successfully or not
if (gmap == null) {
Toast.makeText(getActivity(), "Sorry! unable to create maps", Toast.LENGTH_SHORT).show();
}
}
}
#Override
public void onResume() {
super.onResume();
initilizeMap();
}
}
And my about_us.xml is

As I am completely new to Fragment. Someone pls tell me a noob way to fix it. Thanks a lot in advance.

add fragment to backstack before committing fragmnetTransaction
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.addToBackStack(null);
ft.replace(R.id.content_frame, fragment).commit();

Fragment with mapFragment in layout crashes when you resume cause for a fragment onCreateView is called every time you visit it every time.
Try to make your rootView static like below,
public static View mRootView;
public static boolean mOnRangeChange= false;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if(mRootView==null){
mRootView = inflater.inflate(R.layout.fragment_map, container, false);
}else{
ViewGroup parent = (ViewGroup) mRootView.getParent();
if (parent != null)
parent.removeView(mRootView);
}
map_layout = (FrameLayout) mRootView.findViewById(R.id.map_layout);
mcategory = (Button) mRootView.findViewById(R.id.contact_categories);
mSharedpreferenceUtility = SharedpreferenceUtility.getInstance(getActivity());
mcategory.setOnClickListener(this);
try {
initializeMap(mRootView);
} catch (Exception e) {
e.printStackTrace();
}
return mRootView;
}
