Java 从android联系人列表检索到错误的联系人数据-如何更正？

我在我的应用程序中遇到了一些不寻常的行为-我无法理解为什么，但当用户从我的listview中选择联系人时，后来从手机中检索到的联系人不知何故不是用户选择的联系人

已更新新代码，仍不工作

    public class nominateContactsActivity extends ListActivity {
public String strName;
public String strTelNo;
public static final String PREFS_NAME = "locationPrefs";
public static final ArrayList<NameValuePair> contactsArray = new ArrayList<NameValuePair>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);

setContentView(R.layout.nominatecontactsactivitytest);

this.getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
this.getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

//String[] projection = new String[] { ContactsContract.PhoneLookup.NUMBER};
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '1'";
Cursor cursor = managedQuery(ContactsContract.Contacts.CONTENT_URI,null, selection, null, null);
startManagingCursor(cursor);
String[] columns = new String[] { 
        ContactsContract.Contacts.DISPLAY_NAME
        };

int[] to = new int[] { android.R.id.text1 };

SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_multiple_choice, cursor, columns, to);
this.setListAdapter(adapter);

Button finishButton = (Button) this.findViewById(R.id.finishButton);
finishButton.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {

        SimpleCursorAdapter adapter = (SimpleCursorAdapter) nominateContactsActivity.this.getListAdapter();
        ListView lv = nominateContactsActivity.this.getListView();
        SparseBooleanArray selectedItems = lv.getCheckedItemPositions();
        Cursor contactsCursor = adapter.getCursor();

        /*for (long id : lv.getCheckedItemIds()) {
            String selection = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?";
            String[] args = new String[] { String.valueOf(contactId) };
            Cursor cursor=managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, selection, args, null);
        }*/


        for (long id : lv.getCheckedItemIds()) {

            }
        ;}
            try {

在

onClick

中，您拥有适配器。从中，您可以获得联系人的光标

Cursor contactsCursor = adapter.getCursor();

在循环中，您可以获得联系人id：

contactsCursor.moveToPosition(selectedPosition);
long contactId = contactsCursor.get(contactsCursor.getColumnIndex(BaseColumn._ID));

从那里，您可以按如下方式搜索手机：

String selection = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?";
String[] args = new String[] { String.valueOf(contactId) };
Cursor cursor=managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, selection, args, null);
if (cursor.moveToFirst()) {
    // Get content here
}

从那里，您可以使用已获得的光标

编辑-简化（重新编辑，id实际上是contactId） 您可以简单地在此循环：

for (long contactId : lv.getCheckedItemIds()) {
    String selection = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?";
    String[] args = new String[] { String.valueOf(contactId) };
    Cursor cursor=managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, selection, args, null);
    if (cursor.moveToFirst()) {
        // Get content here
    }
}

您正在显示联系人，但正在枚举电话。您必须找到联系人id，然后使用此id在电话表上进行查询。谢谢，这非常有用-错误现在非常明显。我该如何解决这个问题呢？花了整整一周的时间才把头发撕成这样！非常感谢您的帮助谢谢-我已尝试集成此代码，但没有logcat显示indexoutofbounds错误。我已经编辑了上面的代码。你能发布这个异常的stacktrace吗？另外，我想简化一下。您可以直接从listview:getCheckedItemIds（）获取联系人ID，并循环这些ID查询电话表更新了我的问题。我来换一下contactID部分。再次感谢您的帮助我们遗漏了一个部分：在使用游标之前，在创建游标时必须首先调用cursor.moveToFirst。（我已将其添加到我的答案中）

for (long contactId : lv.getCheckedItemIds()) {
    String selection = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?";
    String[] args = new String[] { String.valueOf(contactId) };
    Cursor cursor=managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, selection, args, null);
    if (cursor.moveToFirst()) {
        // Get content here
    }
}
