在我的程序中，我必须在两个活动之间传递一个自定义对象。第二个活动在单击第一个活动中的列表视图项后开始。第一个活动的ontemclick中的代码是：
public void onItemClick(AdapterView<?> arg0, View v,
int position, long arg3) {
Intent userProfileIntent = new Intent(v.getContext(),
UserProfileActivity.class);
Bundle bundle = new Bundle();
bundle.putSerializable("contact", new ContactSerializer(
sortContacts.get(position)));
userProfileIntent.putExtras(bundle);
v.getContext().startActivity(userProfileIntent);
}
第二个活动的代码是：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.userprofile_layout);
ContactSerializer serializer = (ContactSerializer) getIntent()
.getSerializableExtra("contact");
CustomObj contact = serializer.getContact();
可序列化对象的代码是：
public class ContactSerializer implements Serializable {
private CustomObj contact;
public ContactSerializer(CustomObj contact) {
this.contact = contact;
}
public CustomObj getContact() {
return contact;
}
}

当我尝试启动第二个活动（在线v.getContext.startActivity….）时，应用程序崩溃。有什么想法吗？
最佳答案
您的customobj还应该实现可序列化：
原因：java.io.NotSerializableException:com.customobj
如果customobj再次包含其他对象，请确保这些对象也实现可序列化。您不必寻找简单的类型，比如string或double，因为它们实现了可序列化。
关于android - 在两个 Activity android之间传递可序列化的自定义对象时出错，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/17571611/
