这个是因为没有设置动画,但是设置了transaction导致,按下面改动代码

改动前:

supportFragmentManager
            .beginTransaction()
            .replace(R.id.content, fragment)
            .addToBackStack(fragment.toString())
            .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
            .commit()

改动后

  supportFragmentManager
            .beginTransaction()
            .replace(R.id.content, fragment)
            .addToBackStack(fragment.toString())
            //.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN) //注释掉
            .commit()
E/FragmentManager: No field with the name mListener is found in Animation class
