传递一个 ArrayList<Object>从一个意图到另一个意图 [英] Passing an ArrayList&lt;Object&gt; from one Intent to another

问题描述

我在 ActivityA 中创建了一个 ArrayList，我想将它传递给 ActivityB.

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

活动A:

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
    }
}

我已经尝试了一种方法，但没有成功.传递对象的 ArrayList 是否需要其他东西?

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

您可以通过使用 serializable 或parcelable 传递自定义定义对象的arraylist.

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