传递ArrayList< Object>.从一个意图到另一个 [英] Passing an ArrayList<Object> from one Intent to another

问题描述

我已经在ActivityA中创建了一个ArrayList，我想将其传递给ActivityB.

I have created an ArrayList in ActivityA and i want to pass it to ActivityB.

ActivityA:

ActivityA:

ArrayList<CardDetails> cardDetailsToPass = new ArrayList<>();

        if (v.getId() == balance.getId()){
            for(CardDetails cardDetails : cardDetailsArrayList){
                int clientID = cardDetails.getClientID();
                int cardID = cardDetails.getCardID();
                int cardNo = cardDetails.getCardNo();
                int balance = cardDetails.getCardBalance();
                int availableBalance = cardDetails.getCardAvailableBalance();
                int limit = cardDetails.getCardLimit();
                int expDate = cardDetails.getExpDate();
                String status = cardDetails.getStatus();

                cardDetailsToPass.add(new CardDetails(clientID,cardID,cardNo,balance,availableBalance,limit,expDate,status));

                Log.d("Adapter","clientID               "+cardDetails.getClientID());
                Log.d("Adapter","cardID                 "+cardDetails.getCardID());
                Log.d("Adapter","cardNo                 "+cardDetails.getCardNo());
                Log.d("Adapter","cardBalance            "+cardDetails.getCardBalance());
                Log.d("Adapter","cardAvailableBalance   "+cardDetails.getCardAvailableBalance());
                Log.d("Adapter","cardLimit              "+cardDetails.getCardLimit());
                Log.d("Adapter","cardExpDate            "+cardDetails.getExpDate());
                Log.d("Adapter","cardStatus             "+cardDetails.getStatus());

            }

            Intent intent = new Intent(context, CardStatementActivity.class);
            intent.putExtra("cardDetailsToPass",cardDetailsToPass);
            context.startActivity(intent);

活动B:

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_card_statement);



    Bundle extras = getIntent().getExtras();
    if(extras != null){
       //get the ArrayList here
    }
}

我尝试了一种方法，但是没有成功.传递对象的ArrayList是否还需要其他内容吗?

I've tried one method of doing this but with no success. Does passing an ArrayList of Objects require something else ?

推荐答案

您可以使用可序列化或可打包的方式传递自定义定义对象的数组列表.

You can pass the arraylist of your custom define object either by using serializable or parcelable.
