    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=".MainActivity" >

    <Button

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="100dp"
        android:text="Button" />

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button button= (Button)findViewById(R.id.button);
        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                initiatePopupWindow();
            }
        });

    }


    private void initiatePopupWindow() 
    {
        try 
        {

            //We need to get the instance of the LayoutInflater, use the context of this activity
            LayoutInflater inflater = (LayoutInflater) MainActivity.this
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            //Inflate the view from a predefined XML layout
            View layout = inflater.inflate(R.layout.popupstellodetailpage,
                    (ViewGroup) findViewById(R.id.popuplayout));

            // create a 300px width and 470px height PopupWindow
            pw = new PopupWindow(layout, 300, 470, true);

            // display the popup in the center
            pw.showAtLocation(layout, Gravity.CENTER, 0, 0);

这可能帮助您检查这里点击这里所有你需要的可能性显示地图是完全填充或者不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"/>

Answer 2:

因为我发现他们是仅有的两个傻问题..你只需要改变这个片段

                <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" />

这个..

                <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" />

和改变线在方法[initiatePopupWindow]

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

这个..

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