send.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
      String text =  editText.getText().toString();
       MyFragment5 fragment5 = new MyFragment5();
       Bundle bundle = new Bundle();
       bundle.putString("name", text);
       fragment5.setArguments(bundle);
       FragmentManager fragmentManager = getFragmentManager();
       FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
       fragmentTransaction.add(R.id.layout1, fragment5, "fragment5555");
       fragmentTransaction.commit();
       Toast.makeText(Main4Activity.this,"向Fragment发送数据"+text,Toast.LENGTH_SHORT).show();
   }
