用 FragmentManager 替换时使用 GoogleMaps 崩溃 app
我要用下面的代码来加载的片段的项已被选定在 NavigationDrawer，然而 MapFragment 包含它里面的谷歌地图片段和它崩溃后试图打开它第二次。
这里是我使用的代码：
@Override public void onNavigationDrawerItemSelected(int position) { // update the main content by replacing fragments FragmentManager fragmentManager = getSupportFragmentManager(); if (position == 0) { fragmentManager.beginTransaction() .replace(R.id.container, MapFragment.newInstance("a", "b")) .commit(); } else { fragmentManager.beginTransaction() .replace(R.id.container, PlaceholderFragment.newInstance(position + 1)) .commit(); } }在这里是的日志：

更新
fragment_map.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.br.remotepark.fragments.MapFragment"> <com.sothree.slidinguppanel.SlidingUpPanelLayout android:id="@+id/sliding_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="bottom"> <fragment android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" android:name="com.google.android.gms.maps.MapFragment" /> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:background="#eee" android:orientation="vertical" android:clickable="true" android:focusable="false"> <LinearLayout android:layout_width="match_parent" android:layout_height="68dp" android:orientation="horizontal"> <TextView android:id="@+id/name" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:textSize="14sp" android:gravity="center_vertical" android:paddingLeft="10dp" /> <Button android:id="@+id/follow" android:layout_width="wrap_content" android:layout_height="match_parent" android:textSize="14sp" android:gravity="center_vertical|right" android:paddingRight="10dp" android:paddingLeft="10dp" /> </LinearLayout> </LinearLayout> </com.sothree.slidinguppanel.SlidingUpPanelLayout></RelativeLayout>解决方法 1:
重复的 ID 问题被有关使用嵌套的片段不正确方式。
来自： http://developer.android.com/about/versions/android-4.2.html#NestedFragments
注：你不能膨胀布局到一个片段当该布局包含
<fragment>。动态地添加到一个片段时只支持嵌套的片段。
所以您 fragment_map.xml 不能直接包含 com.google.android.gms.maps.MapFragment 。替换它的 FrameLayout id 为 map_container 和尝试像这样：
public class MyFragmentWithMap extends Fragment { private MapFragment fragment; private GoogleMap map; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_map, container, false); } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); FragmentManager fm = getChildFragmentManager(); fragment = (MapFragment) fm.findFragmentById(R.id.map_container); if (fragment == null) { fragment = MapFragment.newInstance(); fm.beginTransaction().replace(R.id.map_container, fragment).commit(); } } @Override public void onResume() { super.onResume(); setUpMapIfNeeded(); } // ...}请注意，使用 getChildFragmentManager 。
