谢谢
Is there any correction in java code? please help me to solve this problem.

推荐答案
以下变量添加到您的片段类：
Add the following variable to your Fragment class:
private static View view;
然后在同一片段类尝试更换onCreateView方法：
Then in that same fragment class try replacing the onCreateView Method:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if(view != null)
{
ViewGroup parent = (ViewGroup) view.getParent();
if(parent != null)
{
parent.removeView(view);
}
}
try
{
view = inflater.inflate(R.layout.fragment_places, container, false);
}
catch(InflateException e){
// map is already there, just return view as it is
}
return view;
}
