在很多时候都会遇到这样的问题

我在调用百度地图时就遇到了这样的问题

main.xml

<com.baidu.mapapi.map.mapView
        android:id="@+id/bmapsView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true" >
    </com.baidu.mapapi.map.mapView>

出现了以上错误

更改为：

mail.xml

 <com.baidu.mapapi.map.MapView
        android:id="@+id/bmapsView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true" >
    </com.baidu.mapapi.map.MapView>

就可以运行了，这里有两种可能一是没事填写前面正确的包名，例如 <MapView></MapView>

                            另外一种就是本例类名写错了，总之，出现这个错误的原因就是没有找到对应的类

运行效果：
