如何将Address对象数组传递给其他Acitvity

Question

我正在尝试通过Intent对象将Address对象数组传递给另一个Activity.

当Address类实现Parcelable接口时,我尝试执行以下操作.我从Geocoder对象获得了一个List Address对象,我将其转换为Address对象数组.然后我将此数组放入Intent并调用该活动.

final Address[] addresses = addresseList.toArray(new Address[addresseList.size()]);

final Intent intent = new Intent(this, SelectAddress.class);
intent.putExtra(SelectAddress.INTENT_EXTRA_ADDRESSES, startAddresses);

startActivityForResult(intent, REQUEST_CODE_ACTIVITY_SELECT_ADDRESSES);

在其他活动中,我尝试使用以下代码从Intent中检索Address [].但是最后一行的调用以ClassCastException结束Landroid.os.Parcelable.

Bundle bundle = getIntent().getExtras();            
Address[] addresses = (Address[]) bundle.getParcelableArray(INTENT_EXTRA_ADDRESSES);

我究竟做错了什么？我如何检索地址[].

Answer 1

问题是铸造.尝试:

Bundle bundle = getIntent().getExtras();
Parcelable[] parcels = bundle.getParcelableArray(INTENT_EXTRA_ADDRESSES);

Address[] addresses = new Address[parcels.length];
for (Parcelable par : parcels){
     addresses.add((Address) par);              
}

Answer 2

or on java1.6:
    Parcelable[] x = bundle.getParcelableArray(KEY);
    addresses = Arrays.copyOf(x, x.length, Address[].class);
