how do i solve integrating google map in fragment in android

I have a problem integrating google map in fragment in android. I know how to do it in activity but fragment reference on this site are very old and not working in 2018. I don't have any error.below is fragment file. Any help will be highly appreciated. I have added API key and proper manifest file.
package com.example.narmail.truck30mint.Api.Fragments;

}
});

return rootView;
}
}
and below is my layout file
<?xml version="1.0" encoding="utf-8"?>

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:id="#+id/view_trucks_map"
android:layout_width="match_parent"
android:layout_height="match_parent">
</com.google.android.gms.maps.MapView>
</LinearLayout>
</FrameLayout>

Please follow below step to finish your task. Just need to create 3 files
(1) Create XML layout for map inside your fragment layout fragment_map.xml
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
(2) Create Fragment to load MAP MapFragment.Java
public class MapFragment extends Fragment implements OnMapReadyCallback {
private GoogleMap mMap;
public MapFragment() {
// Required empty public constructor
}
#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 onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
if(getActivity()!=null) {
SupportMapFragment mapFragment = (SupportMapFragment) getActivity().getSupportFragmentManager()
.findFragmentById(R.id.map);
if (mapFragment != null) {
mapFragment.getMapAsync(this);
}
}
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
//Do your stuff here
}
}
(3) Create Activity to load MAP fragment MapsActivity.java
public class MapsActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.content,new MapFragment());
fragmentTransaction.commit();
}
}
For MAP key you need to follow same step you have done in your project. Hope this step will help you.
Inside Gradle please use below gradle
implementation 'com.google.android.gms:play-services-maps:15.0.1'
AndroidManifest.xml define below things.
<uses-permission android:name="android.permission.INTERNET"/>
Inside Application Tag.
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="YOUR MAP KEY" />

Create a menu to switch between different types of map (Google Map API on Android)

I am developing a map app with Google Map V2 on Android Studio 2.3 and I would like to create a menu that allows to switch between different types of map. Below is my MapActivity.java code. Please help.
package net.dada.thm;
import android.database.sqlite.SQLiteOutOfMemoryException;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
import com.google.firebase.appindexing.Action;
import com.google.firebase.appindexing.FirebaseUserActions;
import com.google.firebase.appindexing.builders.Actions;
import static net.dada.thm.R.id.map;
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
public GoogleMap mMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(map);
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
// Add a marker in LOME
LatLng LOME = new LatLng(6.131944, 1.222778);
mMap.addMarker(new MarkerOptions().position(LOME).title("LOME"));
}

You could try this approach:
Create one activity with:
MAPTYPE_ONE tab
MAPTYPE_TWO tab
Example
mMap.setBuildingsEnabled(true);
final float mCameraZoom = 10.00f;
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); //this part;
mMap.setTrafficEnabled(true);
mMap.setIndoorEnabled(true);
so then when you select the first tab, you can see the first type of the map and the second one, you set the map type accordingly;
You really don't need a menu; just a small ViewPager with two items on it!
I hope it helps!

I was able to create Buttons inside LinearLayout with onClick attributes to change map types. However, I lost my app initial state in the layout. I don't know where to insert the following paramters:
map:cameraTargetLat="8.6253268"
map:cameraTargetLng="-1.4193078"
map:cameraTilt="00"
map:cameraZoom="6.5"
map:cameraBearing="00"
map:mapType="normal"
map:uiCompass="true"
map:uiRotateGestures="false"
map:uiScrollGestures="true"
map:uiTiltGestures="false"
map:uiZoomControls="true"
map:uiZoomGestures="true"
Or do I have some scripts in the MapsActiviti.java file that is incompatible to what I want to add to the Activity_maps.xml file? Please help.

How can I pop a listView on top of my map activity?

I've got my new application based on Google Maps activity. I set my onMapLongClickListener to add as many new marker as the user want to. But there is my question: I want to set a ListView on the top of my map in order to allow the user to chose between different marker types. How can I set a ListView that appears when I hold a point on the map and then disappear after the selection of one of its items?
Here is my app code, if it can help you on giving me some solutions!

});
LatLng home = new LatLng(44.42913, 8.84072);
map.addMarker(new MarkerOptions().position(home).title("Home, bitches!"));
map.moveCamera(CameraUpdateFactory.newLatLng(home));
CameraUpdate center = CameraUpdateFactory.newLatLng(home);
map.moveCamera(center);
CameraUpdate zoom = CameraUpdateFactory.zoomTo(17);
map.animateCamera(zoom);
}

// Here I'm supposed to implements thee code of the ListView on the top of the map
}
}

Thanks for you support!!

push a dialog to get the list of markers like
#Override
public void onMapLongClick(LatLng location) {
AlertDialog.Builder builderSingle = new AlertDialog.Builder(context);
builderSingle.setIcon(R.drawable.title_icon_resource);
builderSingle.setTitle("Select One Name:-");
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>();//create adapter with your markers list
builderSingle.setNegativeButton();//to exit directly if you want
builderSingle.setAdapter(arrayAdapter,new DialogInterface.OnClickListener());//set your adapter and listener
builderSingle.show();
}
hope this will helps you

Indoor maps are not appearing in a mapView in a Fragment

I have a google map app that is using a mapview in a fragment to display maps. This is working perfectly except that it doesn't display indoor maps.
I decided to create a stripped down version of my code to find the problem. It still exists :-(
In the documentation for indoor maps it says the following
SetIndoorEnabled
Sets whether indoor maps should be enabled. Currently, indoor maps can
only be shown on one map at a time and by default, this is the first map
added to your application. To enable indoor maps on another map, you
must first disable indoor maps on the original map. If you try to enable
indoor maps when it is enabled on another map, nothing will happen and
this will return false. When Indoor is not enabled for a map, all
methods related to indoor will return null, or false.
I can't see that I've enabled multiple maps but I'm wondering if somehow the use of a fragment confuses it.
Any help/advice would be greatly appeciated.
My MainActivity.java
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity {
Fragment map_fragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_2);
showTheMap();
}
public void showTheMap() {
map_fragment = new MapFragment();
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.map, map_fragment);
ft.commit();
}
}

final FrameLayout parent = (FrameLayout) inflater.inflate(R.layout.fragment_map, container, false);
mapView = (MapView) parent.findViewById(R.id.mapfragment);
mapView.getMapAsync(new OnMapReadyCallback() {
#Override
public void onMapReady(GoogleMap googleMap) {
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(-35.0176402, 138.5459909), 17);
googleMap.animateCamera(cameraUpdate);
}
}
);
mapView.onCreate(savedInstanceState);
return parent;
}

super.onCreate(savedInstanceState);

If you move the code to MainActivity it works perfectly. See code below
MainActivity.Java
public class MainActivity extends AppCompatActivity {
MapView mapView = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_1);
mapView = (MapView) findViewById(R.id.map);
mapView.getMapAsync(new OnMapReadyCallback() {
#Override
public void onMapReady(GoogleMap googleMap) {
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(-35.0176402, 138.5459909), 17);
googleMap.animateCamera(cameraUpdate);
}
}
);
mapView.onCreate(savedInstanceState);
}
#Override
protected void onStart() {
super.onStart();
}
#Override
public void onResume() {
super.onResume();
mapView.onResume();
}
#Override
public void onPause() {
super.onPause();
mapView.onPause();
}
#Override
public void onDestroy() {
super.onDestroy();
mapView.onDestroy();
}
#Override
public void onLowMemory() {
super.onLowMemory();
mapView.onLowMemory();
}
#Override
protected void onStop() {
super.onStop();
}
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mapView.onSaveInstanceState(outState);
}
}
The activity_main_1 xml for this is ....
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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:fitsSystemWindows="true"
tools:context="com.example.program.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
</android.support.design.widget.AppBarLayout>
<com.google.android.gms.maps.MapView
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center" />
</android.support.design.widget.CoordinatorLayout>

The following is a solution for my problem.
Declare myGoogleMap in the MainActivity
public static GoogleMap myGoogleMap = null;
In onMapReady add these lines as the first action to do
if (MainActivity.myGoogleMap != null) {
MainActivity.myGoogleMap.setIndoorEnabled(false);
googleMap.setIndoorEnabled(true);
MainActivity.myGoogleMap = googleMap;
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(-35.0176402, 138.5459909), 17);
MainActivity.myGoogleMap.animateCamera(cameraUpdate);
}
It seems as though getMapAsync is called twice and therefore 2 google maps are created, the second one is being displayed.
As indoor maps only appear on the first map you have to setIndoorEnabled to false for the first map and then setIndoorEnabled to true for the second one.
This seems dodgy to me.
Not sure if its a bug or my lack of understanding.
