Android 应用程序被终止或状态保存时MapFragment被阻止或昏迷

Android 应用程序被终止或状态保存时MapFragment被阻止或昏迷,android,android-fragments,android-mapview,actionbarsherlock,android-maps-v2,Android,Android Fragments,Android Mapview,Actionbarsherlock,Android Maps V2,我在活动中使用MapFragment+ListFragment时遇到问题, 当我使用show()和hide()方法时,一切都正常,但当我将应用程序放在后台并返回时,我会使GoogleMap目瞪口呆或被阻止,我不知道如何解决这个问题。我唯一可以很好地工作的解决方案是使用替换事务,但我不喜欢这种方式,因为在每个事务中,我们都应该启动所有map place引出序号,并且它不会保留您的最后一个摄影机位置,所以。。。我不知道该怎么办 注:我使用SherlockActionBar 提前感谢: 这是我的密码:

在新的地图api(maps V2 android)中,我也面临同样的问题。 但我通过在容器活动中重写onSaveInstance和onRestoreInstance方法解决了这个问题。。 并且不调用super.onSaveInstance()。和super.onRestoreInstance()


这只是一次临时的黑客攻击。。但我想你会启动并运行你漂亮的应用程序。

OMG。。。我花了好几个小时。。。你在哪里找到这个解决方案的??非常感谢…@SandeepDhull您是否在这两个方法中编写了任何代码,
public-void-onSaveInstanceState(Bundle-iCicle)
public-void-onRestoreInstanceState(Bundle-iCicle)
?这就是你所说的方法,对吗?谢谢。是的,代码将一些数据保存在捆绑包中。。相反
