本文介绍了Android InflateException使用SupportMapFragment的片段布局出错(重新创建的片段)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
或多或少地起作用.但是，如果重新创建LocationFragment，则应用程序崩溃.
All more or less works.But if the LocationFragment is recreated, the application falls.

UPD: 我有4个片段
UPD:I have 4 fragments
CaptureFragment(1)-TypeFragment(2)-LocationFragment(3)-OverviewFragment(4)
CaptureFragment(1) - TypeFragment(2) - LocationFragment(3) - OverviewFragment(4)
当我快速在以下位置之间移动时:
When I quickly move between:
TypeFragment-LocationFragment
TypeFragment - LocationFragment
或
LocationFragment-OverviewFragment
LocationFragment - OverviewFragment
一切正常.
但是，如果我移动CaptureFragment(1)-> TypeFragment(2)-> LocationFragment(3)
然后
LocationFragment(3)-> TypeFragment(2)-> CaptureFragment(1)
然后
CaptureFragment(1)-> TypeFragment(2)
它坏了.
我知道创建TypeFragment时会创建它，并创建下一个活动CaptureFragment.此时，应用程序退出.
有人知道如何解决吗?
推荐答案
这是我在片段中加载地图布局的方式:
This is how I load my map layout in a fragment:
private View view;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
if (view != null) {
ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null)
parent.removeView(view);
}
try {
view = inflater.inflate(R.layout.map_fragment_location, container, false);
} catch (InflateException e) {
/* map is already there, just return view as it is */
}
ButterKnife.bind(this, view);
SupportMapFragment mapFragment = (SupportMapFragment)getChildFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
return view;
}
这有助于检查布局，如果已经存在，则无需再次创建！
This helps check your layout and if it already exists, you don't have to create again!
请尝试一下，让我知道它的运行方式！
Please try it and let me know how it goes!
