android - Double values for Longitude and Latitude not passing to googlemap Marker -

i have dataobject contains longs latitude , longitude. passing these method in fragment, calls parent activity method show googlemap.

the problem is, longitude , latitude keep resulting (0,0). have checked object setting , getting correct figures.

the figures correct in fragment , in call showmap, marker keeps showing default 0,0.

i have map in activity xml, within framelayout, change visibility. (i think problem, it's blank map)

i have spent hours on this, , have come here, cap in hand.

this relevant parts of code:

my fragment code:

/**  * latitude , longitude dataobject , pass  * showmap method of activity.  */ public void showmap() {      double lat = dataobject.getlatitude();      double long_ = dataobject.getlongitude();      string name = dataobject.getname();      ((myactivity) getactivity()).showmap(lat, long_, name); } 

my activity code:

public void showmap(double lat, double _long, string _title) {     googlemap googlemap = ((mapfragment) getfragmentmanager().                 findfragmentbyid(r.id.map)).getmap();     googlemap.setmaptype(googlemap.map_type_hybrid);     marker marker = googlemap.addmarker(new markeroptions()                 .position(new latlng(lat, _long)).title(_title));     googlemap.movecamera(cameraupdatefactory.zoomto(5f)); } 

my activity xml:

<relativelayout style="@style/rlayout1" xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/my">   ....  <framelayout     android:visibility="gone"     ...     <fragment         android:id="@+id/map"         android:layout_height="match_parent"         android:layout_width="match_parent"         android:name="com.google.android.gms.maps.mapfragment"/> 

i figure i'm missing essential, can't figure out is.

adding logs:

googlemap googlemap = ((mapfragment) getfragmentmanager().                 findfragmentbyid(r.id.map)).getmap(); //log. log.d("1. act lat="+string.valueof(lat),"act long="+string                 .valueof(_long) ); googlemap.setmaptype(googlemap.map_type_hybrid); //log. log.d("2. act lat=" + string.valueof(lat),                 "act long=" + string.valueof(_long)); marker marker = googlemap.addmarker(new markeroptions()                 .position(new latlng(lat, _long)).title(_title)); //log. log.d("3. act lat="+string.valueof(lat),"act long="+string                 .valueof(_long) ); googlemap.movecamera(cameraupdatefactory.zoomto(5f)); //log. log.d("4. act lat="+string.valueof(lat),"act long="+string                 .valueof(_long) ); framelayout framelayout =                 (framelayout) findviewbyid(r.id.third); log.d("5. act lat="+string.valueof(lat),"act " +                 "long="+string                 .valueof(_long) ); framelayout.setvisibility(view.visible); log.d("6. act lat=" + string.valueof(lat),                 "act long=" + string.valueof(_long));

after confirming markers getting placed correctly, looks issue getting current view lined correctly.

this should it:

        latlng latlng = new latlng(lat, _long);          marker marker = googlemap.addmarker(new markeroptions()                 .position(latlng).title(_title));          cameraposition cameraposition = new cameraposition.builder()                 .target(latlng).zoom(5).build();          googlemap.animatecamera(cameraupdatefactory                 .newcameraposition(cameraposition)); 

you might need add these imports:

import com.google.android.gms.maps.cameraupdatefactory; import com.google.android.gms.maps.model.cameraposition;
