调用DialogFragment出现的Can not perform this action after onSaveInstanceState

代码里面用如下的业务场景：进页面并判断是否签到，没有签到就跳转至一个DialogFragment

最开始的做法是如下：

SignInFragment signInFragment = new SignInFragment();

signInFragment.setTargetFragment(LauncherFragment.this,ConstantNewValue.FRAGMENT_RESPONSE_CODE_SIGN);

signInFragment.show(getActivity().getSupportFragmentManager(), "signInFragment");

结果报错

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

检查发现show()方法调用的还是fragment.commit()的方法

    public void show(FragmentManager manager, String tag) {
        mDismissed = false;
        mShownByMe = true;
        FragmentTransaction ft = manager.beginTransaction();
        ft.add(this, tag);
        ft.commit();
    }

所以针对DialogFragment修改如下

SignInFragment signInFragment = new SignInFragment();                                  

signInFragment.setTargetFragment(LauncherFragment.this,ConstantNewValue.FRAGMENT_RESPONSE_CODE_SIGN);                        

holder.fragmentManager.beginTransaction().add(signInFragment,"signInFragment").commitAllowingStateLoss();
