我想在活动之间发送带有hashmap的arraylist但是给我带有hashmap的null arraylist.

发件人活动

ArrayList<HashMap<String,String>> childgame = new ArrayList<HashMap<String,String>>(); 
Intent ordernow= new Intent(CategoryActivity.this,OrderDetailActivity.class);
ordernow.putExtra("orderlist",childgame);                                     
startActivity(ordernow);

接收者活动

Intent intent = getIntent();
Bundle bundle =intent.getExtras();
bundle.getSerializable("orderlist");
