Question

我正在尝试使用intent从MapActivity启动Activity。

以下是我定义MapActivity

的方式

public class googlemap extends MapActivity 
{
   /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
       ... //logic code
    }
}

我正在尝试使用以下MapActivity从Activty启动此Intent：

//Viewreport is the Activity name
intent = new Intent(Viewreport.this,googlemap.class);
startActivity(intent);

它在logcat中给出了以下错误：

另外，我在Manifest.xml文件中添加了以下内容：

<activity android:name=".googlemap" android:label="@string/app_name">
   <intent-filter>
      <action android:name="android.intent.action.MAIN" />                
      <category android:name="android.intent.category.DEFAULT" />
   </intent-filter>
</activity>

有人可以告诉我这里缺少什么。

谢谢！
