所以读书，它说，在XML文件行5.这是XML文件：

So reading that it says the XML file line 5. This is the XML file:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <fragment
        android:id="@+id/the_map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <Button
        android:id="@+id/btn_filerView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="10dp"
        android:paddingTop="10dp"
        android:drawableRight="@drawable/magglasswhite"
        android:background="@android:color/transparent"
        android:onClick="filterView" />

</FrameLayout>

这恰好是＆LT;片段所以..错误与片段是吗？我真的不知道怎么回事。任何想法，为什么这会引发错误？

Which happens to be <fragment so.. the error is with the fragment yeah? I dont really know whats going on. Any ideas why this throws an error?

推荐答案

我一直在争取这一整天同样的问题今天。我得到了我先前的工作。这里就是我所做的：当改变片段显示，我首先删除旧mapFragment，然后添加新的整理碎片时做什么，我通常做

I've been fighting with this same issue all day today. I got mine working earlier. Here's what I did: When changing the fragment showing, I first remove the old mapFragment, then do what I normally do when adding new fragments.

Fragment oldMapFrag = getSupportFragmentManager().findFragmentById(R.id.map);
if(oldMapFrag != null) {
    getSupportFragmentManager().beginTransaction().remove(oldMapFrag).commit();
    manager.popBackStack();
    ViewGroup container = (ViewGroup)findViewById(R.id.content);
    if(container != null)
        container.removeAllViews();
}

当我想再次查看mapFragment，我删除了previous片段然后再次膨胀与mapFragment的观点：

When I want to view the mapFragment again, I remove the previous fragment then inflate the view with the mapFragment again:

Fragment currentFrag = getSupportFragmentManager().findFragmentById(R.id.content);
if(currentFrag != null) {
    getSupportFragmentManager().beginTransaction().remove(currentFrag).commit();
    manager.popBackStack();
}
View mapView = inflator.inflate(R.layout.store_finder, container, true);

我不知道为什么 getSupportFragmentManager（）的BeginTransaction（）删除（oldMapFrag）.commit（）; 工作的第一步，因为你不应该能够去除XML定义的片段，但这为我工作。我希望它能帮助。

I don't know why getSupportFragmentManager().beginTransaction().remove(oldMapFrag).commit(); works in the first step because you shouldn't be able to remove fragments defined in XML, but this does work for me. I hope it helps.
