我需要你的帮助......我一直工作到3天。我的应用正在使用片段。 其中一个片段必须显示Android版Google Maps V2 api中的地图。
目前,我正在使用MapFragment,但毫不奇怪,片段中的片段不是一个好主意,但它有效,地图正在显示,我可以编辑它但是当我切换主片段并返回时它
引起:java.lang.IllegalArgumentException:二进制XML文件行#59:复制id 0x7f070041,标记为null或父ID为0x7f070040,另一个片段为com.google.android.gms.maps.MapFragment
在android.app.Activity.onCreateView(Activity.java:4252)
在android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:673)
当我继续另一个片段并返回包含地图的片段时,这就是原因。 我正在寻找3天来解决这个问题,但没有很好的结果。
为了继续,我有一个Activity调用一个片段,该片段在布局文件中包含一个MapFragment。 如果您需要更多,请问:)
由于
编辑: 以下是在主Activity
中更改Fragment的代码private void swtichFragment(Fragment fragment, Bundle bundle)
{
fragment.setBundle(this, bundle);
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.rightFragmentPlaceHolder, fragment);
fragmentTransaction.commit();
mRightFragment = fragment;
}

使用SupportMapFragment克服此错误:
片段布局
<fragment
android:id="@+id/googleMap"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
在片段onCreateView
SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.googleMap);
if (mapFragment != null) {
mapFragment.getMapAsync(this);
}
由于您的布局位于Fragment's
布局中,因此SupportMapFragment
是您片段的子布局。因此,使用getChildFragmentManager()
Fragment's FragmentManager

在Fragment的布局中使用MapView而不是MapFragment。记得调用MapView的生命周期方法:
如here所述。
顺便说一下。你不应该使用MapFragment,只能使用SupportMapFragment和support library。

如果切换到支持库,可以使用注释#1中的代码: http://code.google.com/p/gmaps-api-issues/issues/detail?id=5064#c1

在片段内显示MapFragment(NestedFragment): 此时我相信你已经
了where.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:orientation="vertical" >

android:layout_height="0dp"
android:layout_weight="1.03"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/mapwhere" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
类:
public class WhereFragment extends SupportMapFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
super.onCreateView(inflater, container, savedInstanceState);
View root = inflater.inflate(R.layout.where, null, false);
initilizeMap();
return root;
}
private void initilizeMap()
{
mSupportMapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.mapwhere);
if (mSupportMapFragment == null) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
mSupportMapFragment = SupportMapFragment.newInstance();
fragmentTransaction.replace(R.id.mapwhere, mSupportMapFragment).commit();
}
if (mSupportMapFragment != null)
{
googleMap = mSupportMapFragment.getMap();
if (googleMap != null)
googleMap.setOnMapClickListener(new OnMapClickListener()
{
@Override
public void onMapClick(LatLng point)
{
//TODO: your onclick stuffs
}
});
}
}
}
文档:
嵌套片段您现在可以在片段中嵌入片段。这是 适用于您想要放置动态的各种情况 和可重用的UI组件到一个本身就是动态的UI组件中 并可重复使用。例如,如果使用ViewPager创建片段 向左和向右滑动并消耗大部分屏幕空间, 您现在可以将片段插入每个片段页面。
要嵌套片段,只需在上面调用getChildFragmentManager() 要添加片段的片段。这会返回一个 像你通常那样使用的FragmentManager 用于创建片段事务的顶级活动。例如, 这里有一些代码可以在现有的Fragment中添加一个片段 类:
Fragment videoFragment = new VideoPlayerFragment(); FragmentTransaction事务= 。getChildFragmentManager()的BeginTransaction(); transaction.add(R.id.video_fragment,videoFragment).commit();从 在嵌套片段中,您可以获得对父级的引用 通过调用getParentFragment()来片段化。
Android支持库现在也支持嵌套片段,所以你 可以在Android 1.6及更高版本上实现嵌套片段设计。
注意:在布局时,您无法将布局扩展为片段 包括一个。仅在添加时支持嵌套片段 一个动态的片段。

在您的布局文件
中<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
在您的片段 onCreate()
中,使用childFragmentManager
引用片段布局文件中的地图片段 >
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
val mapFragment: SupportMapFragment = childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment
// Set callback on the fragment
