MapFragment的片段,替代方案?(MapFragment in Fragment, alte

2019-07-21 16:58发布

我需要你的帮助......我在这工作,直到3天。 我的应用程序正在与片段。 其中一个片段能够显示从谷歌地图API V2为Android的地图。

目前,我使用的是MapFragment,但毫无疑问,在片段的片段是不是个好主意,但它的工作原理,地图上显示的是,我可以编辑,但是当我切换主片段,并返回就可以了。

java.lang.IllegalArgumentException异常:二进制XML文件行#59:副本ID 0x7f070041,标记为空,或父ID 0x7f070040与com.google.android.gms.maps.MapFragment另一个片段所造成

在android.app.Activity.onCreateView(Activity.java:4252)

在android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:673)

这是因为当我去另一个片段,并返回到其中包含的地图之一。 我在寻找,直到3天,以解决这一问题,但没有很大的成绩。

要恢复你的,我有它调用包含在布局文件MapFragment片段的活动。 如果您需要更多,只问:)

谢谢

编辑:这是改变片段的主要活动代码

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;
}

Answer 1:

使用MapView的,而不是MapFragment在你的碎片的布局。 记得拨打MapView类的生命周期方法:

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

作为描述在这里 。

顺便说一句。 你不应该使用MapFragment,只有SupportMapFragment和支持库 。

编辑:

如果切换到支持库,你可以使用代码注释这里为#1: http://code.google.com/p/gmaps-api-issues/issues/detail?id=5064#c1



Answer 2:

使用SupportMapFragment克服这种错误:

在片段布局

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

在您的片段onCreateView

SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.googleMap);

        if (mapFragment != null) {
            mapFragment.getMapAsync(this);
        }

因为你的布局是在Fragment's布局,因此SupportMapFragment是你的片段的子布局。 因此使用getChildFragmentManager()其是Fragment's FragmentManager

如这里所描述

该片段(NestedFragment)内显示MapFragment:在这一点上,我相信你有

  1. 清单上添加必要的权限
  2. 加入谷歌游戏服务作为一个lib项目
  3. 清单文件API密钥。 4。

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
         }
        });
      }
     }
    }

文档

嵌套片段您现在可以在里面嵌入片段的片段。 这是一个不同的要在其中动态和可重复使用的UI组件放置到这本身就是动态的,可重复使用的UI组件非常有用。 例如,如果您使用ViewPager创建轻扫左,右和消耗了大部分的屏幕空间的片段,你现在可以插入片段到每个片段页。

要嵌套片段,只需在其中要添加一个片段片段调用getChildFragmentManager()。 这将返回一个FragmentManager,您可以使用像你通常从顶层活动做创建片段交易。 例如,这里的一些代码,增加了从现有的片段类中的一个片段:

片段videoFragment =新VideoPlayerFragment(); FragmentTransaction交易= getChildFragmentManager()的BeginTransaction(); transaction.add(R.id.video_fragment,videoFragment).commit(); 从嵌套的片段中,您可以通过调用getParentFragment得到父片段的引用()。

Android的支持库现在还支持嵌套的片段,这样你就可以实现在Android 1.6及更高的分片嵌套设计。

注:不能充气布局成片段时布局包括。 当添加到片段动态嵌套片段仅支持。

        android.app.Fragment fragment = getActivity().getFragmentManager()
                .findFragmentById(R.id.map);
        if (null != fragment) {
            android.app.FragmentTransaction ft = getActivity()
                    .getFragmentManager().beginTransaction();
            ft.remove(fragment);
            ft.commit();
        }
    }


}

我的XML文件是这样的: -

<?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" />

而结果如下: -

需要注意的最重要的一点是,不要混用app.Fragment与v4.Fragments其他应用程序会崩溃得很惨。

正如你可以看到我已经使用app.Fragment安装和取下我的MapView的片段

希望这将帮助别人
