检索给定ID的联系人信息（Android）

我正试图根据其

ID

或

查找

检索特定的联系信息（如电话号码、姓名和电子邮件）

首先，我使用此代码读取所有当前联系人数据：

ContentResolver contentResolver = getContentResolver();
    cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI,null,null,null,
            ContactsContract.Contacts.SORT_KEY_PRIMARY + " ASC");

一旦用户选择了一个特定的联系人，我就通过putExtra方法将其

id

传递给另一个活动，该活动旨在读取和显示该联系人的信息

Intent contactDetails = new Intent(ContactsMainActivity.this, ContactsDialogActivity.class);
contactDetails.putExtra("ID",id);
startActivity(contactDetails);

问题就出现在这里。在

ContactsDialogActivity

中，我想通过搜索

id

来检索该联系人的信息：

cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, 
                ContactsContract.Contacts._ID + " = ?", new String[]{String.valueOf(id)},
                ContactsContract.Contacts.SORT_KEY_PRIMARY + " ASC");

但该查询总是向我抛出一个-1索引（它找不到该ID），返回以下错误：

我做错了什么？

假设您有一个有效的contactID，您可以这样做：
Assuming you have a valid contactID, you can do this:

Cursor result = managedQuery(ContactsContract.Contacts.CONTENT_URI, null, 
         ContactsContract.Contacts._ID +" = ?", 
         new String[]{contactID}, null);      
if (result.moveToFirst()) {

    for(int i=0; i< result.getColumnCount(); i++){
        Log.i("CONTACTSTAG", result.getColumnName(i) + ": "
        + result.getString(i));
    }         
}
You will have to change the ContactsContract.Contacts.CONTENT_URI and the where clause to the table that you are querying. The above code will print out a bunch of general info about a contact.

游标结果=managedQuery（ContactsContract.Contacts.CONTENT\u URI，null，
联系人合同联系人。\u ID+“=？”，
新字符串[]{contactID}，null）；
if（result.moveToFirst（））{
for（int i=0；i

听起来您的查询与所有元素都不匹配<如果未找到任何内容，则通常会返回代码>-1。在尝试访问该索引位置处的数组之前，您应该检查它是否为

-1

。但是我认为我没有正确地进行搜索，因为该ID以前是由第一个查询返回的。
