我沒有在Android模擬器中看到谷歌地圖

Question

我已經編譯了Google地圖，以便在Android模擬器中查看。但是，我無法除了以外的任何東西放大和縮小網格。

這是我的清單代碼：

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

    <uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="16" /> 

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

    <uses-permission android:name="android.permission.INTERNET" /> 
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 

    <application 
     android:allowBackup="true" 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <uses-library android:name="com.google.android.maps" /> 

     <activity 
      android:name="com.example.ggl_maps.MainActivity" 
      android:label="@string/app_name" 
      android:theme="@android:style/Theme.NoTitleBar" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
     <activity android:name="HelloItemizedOverlay" > 
     </activity> 
    </application> 

</manifest> 

Java代碼：

import java.util.List;

import com.google.android.maps.MapActivity; 
import com.google.android.maps.MapController; 
import com.google.android.maps.MapView;

    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    try { 
     setContentView(R.layout.activity_main); 
     mapView = (MapView) findViewById(R.id.mapView); 
     mapView.setBuiltInZoomControls(true); 
     mapView.setBuiltInZoomControls(true); 

     List<Overlay> mapOverlays = mapView.getOverlays(); 
     Drawable drawable = this.getResources().getDrawable(R.drawable.ic_launcher); 
     HelloItemizedOverlay itemizedoverlay = new HelloItemizedOverlay(drawable, this); 

     GeoPoint point2 = new GeoPoint(17385812, 78480667); 
     OverlayItem overlayitem = new OverlayItem(point2, "Namashkaar!", 
      "I'm in Hyderabad, India!"); 

     itemizedoverlay.addOverlay(overlayitem); 
     mapOverlays.add(itemizedoverlay); 

     List<Overlay> mapOverlay = mapView.getOverlays(); 
    } catch (Exception e) { 
     // TODO Auto-generated catch block 
     Toast.makeText(getApplicationContext(), e.toString(), 5000).show(); 
    } 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
    } 

    @Override 
    protected boolean isRouteDisplayed() { 
    // TODO Auto-generated method stub 
    return false; 
    } 
} 

overlay.java

import java.util.ArrayList; 

import android.app.AlertDialog; 
import android.content.Context; 
import android.graphics.drawable.Drawable; 

import com.google.android.maps.ItemizedOverlay; 
import com.google.android.maps.OverlayItem; 

public class HelloItemizedOverlay extends ItemizedOverlay { 

    private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); 
    private Context mContext; 

    public HelloItemizedOverlay(Drawable defaultMarker) { 
     super(boundCenterBottom(defaultMarker)); 
    } 

    public void addOverlay(OverlayItem overlay) { 
     mOverlays.add(overlay); 
     populate(); 
    } 

    @Override 
    protected OverlayItem createItem(int arg0) { 
     // TODO Auto-generated method stub 
     return mOverlays.get(arg0); 
    } 

    @Override 
    public int size() { 
     // TODO Auto-generated method stub 
     return mOverlays.size(); 
    } 
    public HelloItemizedOverlay(Drawable defaultMarker, Context context) { 
     super(boundCenterBottom(defaultMarker)); 
     mContext = context; 
    } 

    @Override 
    protected boolean onTap(int index) { 
     OverlayItem item = mOverlays.get(index); 
     AlertDialog.Builder dialog = new AlertDialog.Builder(mContext); 
     dialog.setTitle(item.getTitle()); 
     dialog.setMessage(item.getSnippet()); 
     dialog.show(); 
     return true; 
    } 
} 

我的日誌貓一直在用相同的警告不斷奔跑。

這裏是我的XML文件：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/main" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 

<com.google.android.maps.MapView 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/mapView" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:clickable="true" 
    android:apiKey="AIzaSyB3XULMdQSsa**************************" 
/> 
</LinearLayout> 

這是半對數貓的細節。同樣的運行幾分鐘。
