    }


    private void initiatePopupWindow()

这可能会帮助您Check Here 在此检查所有您需要显示地图是否完全填充的可能性IN AndroidManifest.xml

<permission
        android:name="your.Activity.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />
    <uses-permission android:name="your.Activity.permission.MAPS_RECEIVE" />

<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_CORSE_LOCATION" />

<meta-data    
   android:name="com.google.android.maps.v2.API_KEY"    
   android:value="your_api_key"/>

他们只是我发现的两个愚蠢的问题..你只是改变了这个片段

                <fragment
                android:id="@+id/popupmapview"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_margin="10dp"
                class="com.google.android.gms.maps.SupportMapFragment" />

到此..

                <fragment
                android:id="@+id/popupmapview"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_margin="10dp"
                class="com.google.android.gms.maps.MapFragment" />

并更改方法[initiatePopupWindow]

中的一行

map= ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.popupmapview)).getMap(); 

到此..

map = ((MapFragment) getFragmentManager().findFragmentById(R.id.popupmapview)).getMap();
