所以，我在一个片段（tab）中显示一个Map（使用MapView）并且它工作得非常好，但是我在选项卡的xml中添加了SupportMapFragment，在我尝试重新选择选项卡后它崩溃了。以下是崩溃的完整日志：

我是第一次打开应用程序，它运行正常，直到我尝试重新加载选项卡。 Here is the first tab opened - it is ok和 It crashes after this.
片段在协调器布局中，第一次打开时第一次就可以正常工作。

以下是tab.java中与片段有关的全部代码：
SupportPlaceAutocompleteFragment autocompleteFragment = (SupportPlaceAutocompleteFragment)
getChildFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);
autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
// TODO: Get info about the selected place.
googleMap.clear();
CameraPosition cameraPosition = new CameraPosition.Builder().target(place.getLatLng()).zoom(11).build();
googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
googleMap.addMarker(new MarkerOptions().position(place.getLatLng()).title(place.getName().toString()));
Toast.makeText(getContext(), place.getClass().getName().toString(), Toast.LENGTH_SHORT).show();
}
@Override
public void onError(Status status) {
// TODO: Handle the error.
Log.i("LOGINCAZDEEROARE:", "Error happened: " + status);
Toast.makeText(getContext(), "IT DID NOT WORK", Toast.LENGTH_SHORT).show();
}
});
答案 0 :(得分：1)
我解决了这个问题，希望这对某人有所帮助！ 有人和我有类似的问题，但有一个地图片段。 This answer为我工作。
答案如下
如果n是标签数量，那么：
mViewPager.setOffscreenPageLimit（N）;
查看寻呼机实现队列 所以，你不必让它删除那个片段。 onCreateView是 只召唤一次。
注意：当布局包含a时，您无法将布局扩展为片段。仅在动态添加到片段时才支持嵌套片段
