I want to display my "double CO2Data" in my textView in my info window. I am not sure where and how I write that code. Does anyone have any tips or ideas on how to do that?
My MapsActivity:
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback,
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener,
LocationListener {
private GoogleMap mMap;
GoogleApiClient mGoogleApiClient;
Location mLastLocation;
Marker mCurrLocationMarker;
LocationRequest mLocationRequest;
private boolean initiateApp;
double CO2data = 1.02;
double N2data = 0.002;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
checkLocationPermission();
}
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
initiateApp = true;
}
/**
* Manipulates the map once available.
* This callback is triggered when the map is ready to be used.
* This is where we can add markers or lines, add listeners or move the camera. In this case,
* we just add a marker near Sydney, Australia.
* If Google Play services is not installed on the device, the user will be prompted to install
* it inside the SupportMapFragment. This method will only be triggered once the user has
* installed Google Play services and returned to the app.

@Override

My custom infowindow xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="110dp"
android:layout_height="110dp"
android:orientation="vertical"
android:gravity="center"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/infoText"
android:textColor="#000000"
android:padding="10dp"
android:layout_centerInParent="true"
android:background="#ffffff"
/>
</RelativeLayout>
</LinearLayout>
The code that I used to for the info window
mMap.setInfoWindowAdapter(new InfoWindowAdapter() {
public View getInfoWindow(Marker arg0) {
View v = getLayoutInflater().inflate(R.layout.custom_infowindow, null);
return v;
}
public View getInfoContents(Marker arg0) {
//View v = getLayoutInflater().inflate(R.layout.custom_infowindow, null);
return null;
}
});
