java - 当 fragment 处于​​恢复状态时，如果条件为真，它将返回到创建 View

Question

如果满足特定条件，我希望恢复阶段的 fragment 返回到创建 View 阶段，这可能吗？

 public class FragBeamRec extends Fragment {

        public static FragBeamRec newInstance() {
            FragBeamRec fragment = new FragBeamRec();
            return fragment;
               }

        public FragBeamRec() {
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_frag2, container, false);

    globalvar.booIstrue = false;

            return inflater.inflate(R.layout.fragment_frag2, container, false);
        }

    @Override
        public void onResume(){
        super.onResume();

    if (globalvar.booIstrue){
    // what do i write here to make it back to onCreateView
    }
    }
    }

只需将 onCreateView 逻辑移至单独的方法中即可。这就是窍门。干杯:)

public class FragBeamRec extends Fragment {

 public static FragBeamRec newInstance() {
  FragBeamRec fragment = new FragBeamRec();
  return fragment;
 }

 public FragBeamRec() {}

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
  Bundle savedInstanceState) {
  View rootView = inflater.inflate(R.layout.fragment_frag2, container, false);


  doYourMagicHere();

  return inflater.inflate(R.layout.fragment_frag2, container, false);
 }

 @Override
 public void onResume() {
  super.onResume();


  if (globalvar.booIstrue) {
   // what do i write here to make it back to onCreateView
   doYourMagicHere();
  }
 }
 public void doYourMagicHere() {
  globalvar.booIstrue = false;
 }
}
