我已经完成了所有配置。android hellomap示例例外

这里是我的清单文件：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
     package="com.example" 
     android:versionCode="1" 
     android:versionName="1.0"> 
     <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
    <uses-permission android:name="android.permission.INTERNET" /> 

    <uses-sdk android:minSdkVersion="3" /> 
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> 
    <application android:icon="@drawable/icon" android:label="@string/app_name"> 
    <uses-library android:name="com.google.android.maps" /> 
     <activity android:name="com.example.HelloMap" 
        android:label="@string/app_name"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
    </application> 
</manifest> 

and my layout file main.xml is 
<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/mainlayout" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

    <com.google.android.maps.MapView 
     android:id="@+id/mapview" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:enabled="true" 
     android:clickable="true" 
     android:apiKey="*************" 
    /> 
</RelativeLayout>

而且我Hellomap.java

public class HelloMap extends Activity { 
    LinearLayout linearLayout; 
    MapView mapView; 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.mapview); 
     mapView = (MapView) findViewById(R.id.mapview); 
     mapView.setBuiltInZoomControls(true); 

    } 



    protected boolean isRouteDisplayed() { 
     return false; 
    } 
}

我丢失的东西我想，也许这个问题是谷歌2.1 API？

你有设定为外部库中的谷歌的API项目中使用，而非普通的Android的图书馆吗？ – JRL 2010-06-14 19:47:26

是的，我使用谷歌API 2.1 – avin 2010-06-15 03:38:21

和我有map.jar和android.jar – avin 2010-06-15 03:40:42

我得到了我的answere自己

只看到异常日志

最后几行

MapViews can only be created inside instances of MapActivity. 06-14 22:13:34.031: ERROR/AndroidRuntime(331): at com.google.android.maps.MapView.(MapView.java:281) 06-14 22:13:34.031:

这意味着你需要与MapActivity拓展业务，不活动我想大多数人都知道，但我现在知道了 :)

我有这个问题，并通过以下2个步骤解决它：

1）在AndroidManifest.xml文件的应用程序（重要）元素中放置以下行。

<uses-library android:name="com.google.android.maps" />

2）扩展MapActivity而不是Activity。

享受！

这里我将Activity更改为MapActivity。

所以不是

public class HelloMap extends Activity {

将其更改为

public class HelloMap extends MapActivity {

如果您在使用谷歌地图都是新的，你已经设置了XML和活动，你有这种类型的错误，那么它意味着你没有从MapsActivity扩展你的课程，所以从地图活动中扩展你的课程，它将开始工作！

//活动的错误使用

public class A extends Actvitiy 
{ 
} 
//correct usage 

public class A extedns MapsActivity { 
//your all program... 
}
