Question

我想在listView上获得conctacts，我想要reutilitzate一个SocialAuth代码。在这段代码中，我可以在LogCat上获取ContactList，但不能在listView中获取，我不知道如何做到这一点。此listView位于其他XML上。

我很瞪眼，但我不知道如何调整代码

public void Events(String provider) {

    setContentView(R.layout.contact_list);

    List < Contact > contactsList = adapter.getContactList();




    if (contactsList != null && contactsList.size() > 0) {
        for (Contact p: contactsList) {

            if (TextUtils.isEmpty(p.getFirstName()) && TextUtils.isEmpty(p.getLastName())) {
                p.setFirstName(p.getDisplayName());
            }

            Log.d("Custom-UI", "Display Name = " + p.getDisplayName());
            String ContactNAme = p.getDisplayName();
            //ContactName = new String[] {p.getDisplayName()};
            //mapTo = new int[] {android.R.id.text1};
            Log.d("Custom-UI", "First Name = " + p.getFirstName());
            String ContactFisrtName = p.getFirstName();
            Log.d("Custom-UI", "Last Name = " + p.getLastName());
            String ContactLastName = p.getLastName();
            Log.d("Custom-UI", "Contact ID = " + p.getId());
            String ContactId = p.getId();
            Log.d("Custom-UI", "Profile URL = " + p.getProfileUrl());
            String ContactProfileUrl = p.getProfileUrl();

        }
        //  Log.d("ContactList",mAdapter.toString());
    }
    Toast.makeText(CustomUI.this, "View Logcat for Contacts Information", Toast.LENGTH_SHORT).show();


}

我认为问题是光标，因为我没有任何人，我有这个功能，我觉得它有点像光标

public List<Contact> getContactList() 
{
    try 
    {
        contactsList = new contactTask().execute().get();
    } 
    catch (InterruptedException e) 
    {
        e.printStackTrace();
    } 
    catch (ExecutionException e) 
    {
        e.printStackTrace();
    }

    return contactsList;
}

所以，如果有人可以帮助我，非常感谢。

您需要为列表视图编写自定义适配器。

这是一个很好的例子

  // Call contact thread
