重复ID，标签空，或父ID与com.google.android.gms.maps.MapFragment的另一个片段

我有一个带有三个选项卡的应用程序。

每个选项卡都有自己的布局.xml文件。xml有自己的映射片段。它是应用程序第一次启动时显示的那个。

一切都很好，除了当我在制表符之间改变。如果我尝试切换回地图片段选项卡，我会得到这个错误。在其他选项卡之间切换就可以了。

这里会出什么问题呢?

这是我的主类和main.xml，以及我使用的相关类(您还将在底部找到错误日志)

对于那些仍然遇到这个问题的人来说，确保您不会在Tab中的Map中得到这个错误的最好方法是使Fragment扩展SupportMapFragment，而不是在用于Tab的Fragment中嵌套SupportMapFragment。

我刚刚得到这个工作使用一个ViewPager与FragmentPagerAdapter，与SupportMapFragment在第三个选项卡。

这里是一般的结构，注意没有必要重写onCreateView()方法，也没有必要膨胀任何布局xml:

public class MapTabFragment extends SupportMapFragment 
                                    implements OnMapReadyCallback {

    private GoogleMap mMap;
    private Marker marker;


    public MapTabFragment() {
    }

    @Override
    public void onResume() {
        super.onResume();

        setUpMapIfNeeded();
    }

    private void setUpMapIfNeeded() {

        if (mMap == null) {

            getMapAsync(this);
        }
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {

        mMap = googleMap;
        setUpMap();
    }

    private void setUpMap() {

        mMap.setMyLocationEnabled(true);
        mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        mMap.getUiSettings().setMapToolbarEnabled(false);


        mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {

            @Override
            public void onMapClick(LatLng point) {

                //remove previously placed Marker
                if (marker != null) {
                    marker.remove();
                }

                //place marker where user just clicked
                marker = mMap.addMarker(new MarkerOptions().position(point).title("Marker")
                        .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA)));

            }
        });

    }


}

嵌套片段目前不受支持。试试Support Package，修订版11。

任何人来这里现在得到这种类型的错误时打开一个对话框或其他片段与谷歌的地方AutocompleteSupportFragment，尝试这一行(我不知道这是多么安全，但它为我工作):

.beginTransaction autocompleteFragment.getFragmentManager () () .remove (autocompleteFragment) .commit ();

在你解散/销毁你的碎片之前。

全局声明SupportMapFragment对象

    private SupportMapFragment mapFragment;

在onCreateView()方法中将代码放在下面

mapFragment = (SupportMapFragment) getChildFragmentManager()
            .findFragmentById(R.id.map);
 mapFragment.getMapAsync(this);

在onDestroyView()中放入下面的代码

@Override
public void onDestroyView() {
   super.onDestroyView();

    if (mapFragment != null)
        getFragmentManager().beginTransaction().remove(mapFragment).commit();
}

在你的xml文件中放入下面的代码

 <fragment
    android:id="@+id/map"
    android:name="com.abc.Driver.fragment.FragmentHome"
    class="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

上面的代码解决了我的问题，它的工作很好

我今天已经浪费了几个小时来寻找原因，幸运的是这个问题不是因为MapFragment实现，幸运的是，这并不奏效，因为嵌套片段只通过rev 11的支持库支持。

我的实现有一个带有actionbar(在选项卡模式下)的活动，有两个选项卡(没有viewpager)，一个有地图，另一个有条目列表。当然，我很天真地在我的标签片段中使用MapFragment，等我每次切换回地图标签时，应用程序就崩溃了。

(同样的问题，我也会有情况下，我的制表符片段将膨胀任何布局包含任何其他片段)。

一种选择是使用MapView(而不是MapFragment)，尽管有一些开销(请参阅layout.xml中的MapView Docs作为dropin替代品，另一种选择是使用从rev. 11开始的支持库，但随后采用编程方法，因为布局不支持嵌套片段。或者只是通过显式地破坏片段以编程方式工作(就像Matt / Vidar的答案一样)，顺便说一句:使用MapView(选项1)也能达到同样的效果。

但实际上，我不想每次我tab离开的时候都丢失地图，也就是说，我想把它保存在内存中，只有在活动关闭时才清理，所以我决定在tab时简单地隐藏/显示地图，参见FragmentTransaction / hide

重复ID，标签空，或父ID与com.google.android.gms.maps.MapFragment的另一个片段
