错误信息: 

Caused by: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

 

信息补充:

使用FragmentActvitiy + Fragment

 

错误原因:

    @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.preference_fragment, container);

 

解决办法: 

View v = inflater.inflate(R.layout.preference_fragment, container, false);

 

补充信息:

导致此错误并不一定就是这个原因,大家也能搜到很多其他的原因,这里备注一下。 

之前使用ActionBar里面的Fragment好像是可以的。
