Fragment中的MapFragment,替代方案?

标签: android fragment google-maps-android-api-2 mapfragment

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:

  • 的onCreate(束)
  • 的onResume()
  • 的onPause()
  • 的onDestroy()
  • 的onSaveInstanceState(束)
  • onLowMemory()

here所述。

顺便说一下。你不应该使用MapFragment,只能使用SupportMapFragment和support library

修改

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

As described here

在片段内显示MapFragment(NestedFragment): 此时我相信你已经

  1. 在清单上添加了必要的权限
  2. 将谷歌播放服务添加为lib项目
  3. 清单文件中的
  4. api密钥。 4。
  5. 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:gravity="center"
                android:orientation="vertical" >
             <FrameLayout
               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
             }
            });
          }
         }
        }

    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。

    这也将修复:

}

我的Xml文件如下所示: -

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

结果如下: -

最值得注意的是,DO Not Mix app.Fragment与v4.Fragments else app会严重崩溃。

如您所见,我已使用app.Fragment附加和删除我的MapView片段

希望它会帮助某人

在您的布局文件

<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
        mapFragment.getMapAsync(this)

您可以尝试在FragmentContainerView androidx包的Fragment内添加MapFragment:

答案 7 :(得分:0)

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


View root= inflater.inflate(R.layout.fragment_a_t_m_locations, container, false);
    SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.location_map);
    mapFragment.getMapAsync(googleMap -> {
        mMap=googleMap;
        if(mMap!=null){
            mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        }
    });
