android - Google Maps v2 Implementation into Existing Fragment -
i wondering if shed light on issue i'm facing.
i have app has main activity 4 buttons , fragment, whenever press button fragment changes, far good.
i stumped adding google maps v2 1 of fragments, *eg when press button 2 want load map within fragment present (fragment_place), cannot seem find way , every other question on here solutions don't seem work me.*
any appreciated, i'm not amazing programmer in first place android seems difficult myself.
i have adjusted manifest file have no idea how use existing fragment 'holder' map
main activity
package com.grim.fragments; import android.os.bundle; import android.app.activity; import android.app.fragment; import android.app.fragmentmanager; import android.app.fragmenttransaction; import android.view.view; public class mainactivity extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); } public void selectfrag(view view) { fragment fr = null; if (view == findviewbyid(r.id.button1)) { fr = new fragmentone(); } else if (view == findviewbyid(r.id.button2)) { fr = new fragmentmap(); } else if (view == findviewbyid(r.id.button3)) { fr = new fragmentthree(); } else if (view == findviewbyid(r.id.button4)) { fr = new fragmentfour(); } fragmentmanager fm = getfragmentmanager(); fragmenttransaction fragmenttransaction = fm.begintransaction(); fragmenttransaction.replace(r.id.fragment_place, fr); fragmenttransaction.commit(); } }
activity main

package com.grim.fragments; import android.app.fragment; import android.os.bundle; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; public class fragmenttwo extends fragment { @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { // todo auto-generated method stub return inflater.inflate(r.layout.fragment_two, container, false); } } <?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/relativelayout1" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > </relativelayout> again appreciated driving me mad in don't know start, have semblance of idea of needs doing next.
edit - forgot add i've attempted

i figured out way map running within existing fragment
public class mapfragment extends fragment { mapview map; @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { // inflat , return layout view v = inflater.inflate(r.layout.map_fragment, container, false); map = (mapview) v.findviewbyid(r.id.mapview); map.oncreate(savedinstancestate); return v; } @override public void onresume() { super.onresume(); map.onresume(); } @override public void onpause() { super.onpause(); map.onpause(); } @override public void ondestroy() { super.ondestroy(); map.ondestroy(); } @override public void onlowmemory() { super.onlowmemory(); map.onlowmemory(); } } mapview.xml
<?xml version="1.0" encoding="utf-8"?> <com.google.android.gms.maps.mapview xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/mapview" />
