I have strange issue while using Two SupportMapFragment in two different Fragment in one Activity.
Actually my problem is let say In OneFragment i have SupprtMapFragment added and i add 10 Marker in that map view and now i go to detail page by adding another Fragment and in that it have also SupprtMapFragment now in this Fragment i want to clear it and want to show Only one pin but it Still Showing 11 Marker over map .
Here is my Source code:
public class MapActivity extends FragmentActivity {
private FragmentManager mFragmrg;
public static String TAG_FRAGMENT_HOME="HomeFragment";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
initView();
}
private void initView(){
mFragmrg=getSupportFragmentManager();
MapHomeFragment mMapHomeFragment=new MapHomeFragment();
FragmentTransaction mFt=mFragmrg.beginTransaction();
mFt.replace(R.id.frame_holder, mMapHomeFragment, TAG_FRAGMENT_HOME).addToBackStack(TAG_FRAGMENT_HOME).commit();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.map, menu);
return true;
}
}
XMl Layout of Activity:
<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MapActivity" >
<FrameLayout
android:id="@+id/frame_holder"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</RelativeLayout>
THis Fragment have my First SupportMapFragment where i want to show more then 11 Marker over map and it work well.

OUTPUT Screen Shot:
Now when you click that DetailMap button it will take user to Detail Screen where i want to show only One Marker in that SupportMapFragment but i don't known why it still Showing previous all Marker which i have added in my First Fragment.
My Second Fragment Code:

if(mSupportMapDetail!=null){

Here is my Second screen output:
As you can see in my second screen show it still showing Marker on map Why this happen ?
Can any one give proper solution so when i go back in previous screen it have all Marker remain as same as i have added them .
Replace
mSupportMapDetail=(SupportMapFragment) mFragMrg.findFragmentByTag("map_home_detail");
with
mSupportMapDetail=(SupportMapFragment) mFragMrg.findFragmentById("map_home_fragment_detail");
Also try replacing findFragmentByTag to findFragmentById everywhere..
Replace this code to your second fragment:
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
setUpMap();
}
}
}
private void setUpMap() {
// Hide the zoom controls as the button panel will cover it.
mMap.getUiSettings().setZoomControlsEnabled(false);
// if there were any markers remove them just in case
mMap.clear();
// Add your marker to the map
addMarkersToMap();
// Setting an info window adapter allows us to change the both the contents and look of the
// info window.
mMap.setInfoWindowAdapter(new CustomInfoWindowAdapter());
// Set listeners for marker events. See the bottom of this class for their behavior.
mMap.setOnMarkerClickListener(this);
mMap.setOnInfoWindowClickListener(this);
mMap.setOnMarkerDragListener(this);
}
and in your map_detail_screen.xml add:
<fragment
android:id="@+id/map_home_fragment_detail"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>
// try this way,hope this will help you..
Note : you can not add one fragment inside another fragment.
