我想打开弹出窗口，我使用地图 v2 在弹出窗口中显示地图 v2，但这里没有显示我把我的 xml 布局和活动类

在此处输入图像描述

主要的.xml

<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=".MainActivity" >

    <Button
        android:id="@+id/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" />

</RelativeLayout>

popupstellodetailpage.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/popuplayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/black"
    android:orientation="vertical" >

        <Button

            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Cancel"
            android:layout_gravity="right"
             />

          <fragment
                    android:id="@+id/popupmapview"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"

                    class="com.google.android.gms.maps.SupportMapFragment" />



</LinearLayout>

MapActivity.java

public class MainActivity extends  FragmentActivity {


     PopupWindow pw;
     GoogleMap map;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        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);


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


            Button buttoncancel=(Button)layout.findViewById(R.id.buttoncancel);
            buttoncancel.setOnClickListener(new OnClickListener() 
            {   
                @Override

                {
                     pw.dismiss();
                }

            });

        }
        catch (Exception e)

            e.printStackTrace();

这可能会帮助您检查这里检查这里所有您需要显示地图的可能性是否已满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..您只需更改此片段

                <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" />

并在方法 [initiatePopupWindow] 中更改一行

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

到这个..

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