嫌疑犯是：

m = (MapView)findViewById(R.id.mapView);

哪里m是：

private MapView m;

我不明白我哪里错了。请指导。

在您的布局中，MapView 是否设置为com.google.android.maps.MapView？

（另外，如果您还没有，请在https://developers.google.com/maps/documentation/android/上查看新的 Google Maps API，而不是您正在使用的 API V1）

检查您是否在应用程序清单中为地图声明了 uses-library 标记。

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >

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

我认为您没有从MapActivity扩展。您应该从 MapActivity 而不是 Activity 扩展您的类。您可以从本教程中获得更多帮助：
