DialogFragment IllegalStateException: Can not perform this action after onSaveIn

一、问题

DialogFragment 偶现IllegalStateException: Can not perform this action after onSaveInstanceState。一般的解决方法，使用commitAllowingStateLoss 替代 commit，但DialogFragment的show方法默认使用的commit，无法修改

二、解决方案

public class AllowStateLossDialogFragment extends DialogFragment {
    @Override
    public void show(@NonNull FragmentManager manager, @Nullable String tag) {
        try {
            FragmentManager temp = null;
            // super 里有变量需要赋值
            super.show(temp, tag);
        } catch (Exception e) {
        }

        FragmentTransaction ft = manager.beginTransaction();
        ft.add(this, tag);
        ft.commitAllowingStateLoss();
    }
}

重写父类show方法，传入空的FragmentManager，目的是触发父类show方法里需要赋值的变量被赋值，然后在try-catch之后手动调用commitAllowingStateLoss
