Question

朋友您好我想在我的Android设备上显示地图，所以我的代码如下

main.xml中

 <fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="400dp"
    android:layout_height="400dp"
    />

的Manifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.pakagename.example"
android:versionCode="1"
android:versionName="1.0" >

<!-- android:versionCode="2" -->
<!-- android:versionName="1.1" > -->

<uses-feature
    android:glEsVersion="0x00020000"
     android:required="true"/>

<permission

    android:protectionLevel="signature" />

<uses-permission android:name="com.pakagename.example.permission.MAPS_RECEIVE" />

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>


    <activity
        android:name="pkg.android.rootways.restaurantapp.ReviewActivity"
        android:screenOrientation="landscape"
        android:windowSoftInputMode="adjustPan" />


    </application>

 </manifest>

ReviewActivity.java

 public class ReviewActivity extends FragmentActivity implements LocationListener
 {
           @Override
 protected void onCreate(Bundle savedInstanceState) {
    GoogleMap myMap;
    super.onCreate(savedInstanceState);
    setContentView(R.layout.res_review);

    initMap();
         }

public void initMap() {

    FragmentManager myFragmentManager = getSupportFragmentManager();
    SupportMapFragment mySupportMapFragment = (SupportMapFragment) myFragmentManager
    .findFragmentById(R.id.map);
    myMap = mySupportMapFragment.getMap();

    if (myMap != null)
    {
        System.out.println("MAp");
        myMap.setMyLocationEnabled(true);
        myMap.getUiSettings().setZoomControlsEnabled(true);
        myMap.getUiSettings().setCompassEnabled(true);
        myMap.getUiSettings().setMyLocationButtonEnabled(true);         
        myMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);

    }

    else 
    {
        System.out.println("Null Value");
    }

   }

   }

当我运行ablove代码时，它给了我像

在清单文件中添加：

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

同时检查：Google Maps V2
