推荐答案

这是你的活动是你有数组列表中右键：

This is your activity were you have array list Right:

public List<Contact> getAllContacts() {
List<Contact> ContactpList = new ArrayList<Contact>();

现在当u调用另一个活动然后发送数组对象是这样的：

now when u call another activity then send the array object like this:

Intent intent = new Intent(youractivity.this,youractivity.class);
intent.putExtra("ContactpList ", ContactpList );
startActivity(intent);

现在得到这个数组中，你都呼吁并且是ü希望得到阵列的活动：

now get this array in the activity which you have called and were u want to get the array:

ArrayList<String> resultArray = getIntent().getStringArrayListExtra("ContactpList ");

希望这是你的工作。

Hope it is work for you.
