I am making an Android Application with four Tabs. One of the Tabs is a 'Find Us' tab which should show Google maps with two locations, The User's current position and a Marker.
I already have my main activity which uses a tabhost to generate four tabs, one of which is find us:
import android.app.TabActivity;
import android.content.Intent;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
import android.support.v4.app.FragmentActivity;
public class AndroidTabLayoutActivity extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabHost tabHost = getTabHost();
// Tab for About
TabSpec photospec = tabHost.newTabSpec("About");
// setting Title and Icon for the Tab
photospec.setIndicator("About", getResources().getDrawable(R.drawable.icon_about_tab));
Intent photosIntent = new Intent(this, AboutActivity.class);
photospec.setContent(photosIntent);
// Tab for Facebook
TabSpec songspec = tabHost.newTabSpec("Facebook");
songspec.setIndicator("Facebook", getResources().getDrawable(R.drawable.icon_facebook_tab));
Intent songsIntent = new Intent(this, FacebookActivity.class);
songspec.setContent(songsIntent);
// Tab for Videos
TabSpec videospec = tabHost.newTabSpec("Notices");
videospec.setIndicator("Notices", getResources().getDrawable(R.drawable.icon_youtube_tab));
Intent videosIntent = new Intent(this, YoutubeActivity.class);
videospec.setContent(videosIntent);
// Tab for Map
TabSpec mapspec = tabHost.newTabSpec("Find Us");
mapspec.setIndicator("Find Us", getResources().getDrawable(R.drawable.icon_map_tab));
Intent mapIntent = new Intent(this, MapsActivity.class);
mapspec.setContent(mapIntent);
// Adding all TabSpec to TabHost
tabHost.addTab(photospec); // Adding about tab
tabHost.addTab(songspec); // Adding facebook tab
tabHost.addTab(videospec); // Adding videos tab
tabHost.addTab(mapspec); // Adding map tab
}
//making the tab view:
private View makeTabIndicator(Drawable drawable){
ImageView Tabimage = new ImageView(this);
Tabimage.setImageDrawable(drawable);
Tabimage.setBackgroundResource(R.drawable.icon_about_tab);
return Tabimage;
}}
I have followed the guidance at developers.google.com/maps/documentation/android/map therefore the map class looks like this:
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
public class MapsActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map);}}
And my map.xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
At the moment, that works fine and displays a map, however, to display makers on it, you need to add an overlay. For that, instead of public class MapsActivity extends Activity { it should say public class MapsActivity extends FragmentActivity { Because it is not a FragmentActivity, code like below won't work:
private GoogleMap mMap;
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
mMap.addMarker(new MarkerOptions()
.position(new LatLng(0, 0))
.title("Hello world"));
When I do change it to FragmentActivity the application crashes, logcat below:

I have also added all necessary information into the Manifest.xml (Permissions, API Key etc)
Any help is gratefully appreciated. :)
