我正在尝试应用drawernavigation（我的第一个片段是地图＆amp;其他只是一些具有简单布局的片段）。因此它运行良好＆amp;我可以在我的片段之间导航但是当我返回到第一个片段时，我发生了崩溃

这是我对fragmentActivity的主要布局：

我认为问题出在onResume＆amp; onCreateView方法!! 希望你能帮助我 感谢。
答案 0 :(得分：44)
使用此
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
/>
并覆盖方法onDestroyView()，并将此代码放入onDestroyView()
public void onDestroyView()
{
super.onDestroyView();
Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));
FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
ft.remove(fragment);
ft.commit();
}

尝试重复使用/回收您的布局。 我正在进入＆＃34;复制id＆＃34;使用地图片段时 所以在 onCreateView 而不是
final View rootView = inflater.inflate(R.layout.fragment_profile, container, false);
我正在使用
public class YourFragment extends Fragment {
public YourFragment(){}
...
private static View rootView;
...
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//View rootView = inflater.inflate(R.layout.fragment_layout, container, false);
if (rootView != null) {
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null)
parent.removeView(rootView);
}
try {
rootView = inflater.inflate(R.layout.fragment_layout, container, false);
} catch (InflateException e) {
/* map is already there, just return view as it is */
}
答案 2 :(得分：0)
我认为你必须尝试检索旧的Fragments实例，而不是每次选择抽屉项时重新创建它。在LoginScreen Activity的displayView方法中，您必须在交换机中执行类似的操作：
Fragment fragment = null;
String title = getResources().getString(SOME_FRAGMENT_TITLE);
switch (position) {
case 1:
fragment = (YourFragment) fm.findFragmentByTag(title);
if (fragment == null) fragment = new YourFragment();
break;
}
