“Error inflating class com.google.android.maps.MapView”的确切原因和解决方法是什么

Question

这是我的 map.xml 文件中的内容：

<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="0p8EoZESYekrClENQbOlN5EN16DgXv7Rx0CPTMg"            
            />

Answer 1

您的日志（使用 logcat）或堆栈跟踪中没有更多内容？

Answer 2

您是否将主类扩展为 MapActivity？

public class a extends MapActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

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