根据ID检索联系人信息(Android)

// 定义要查询的联系人ID
String contactId = "123";

// 构建查询条件
String[] projection = {ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.PHOTO_URI};
String selection = ContactsContract.Contacts._ID + " = ?";
String[] selectionArgs = {contactId};

// 执行查询
Cursor cursor = getContentResolver().query(
    ContactsContract.Contacts.CONTENT_URI,
    projection,
    selection,
    selectionArgs,
    null
);

// 处理查询结果
if (cursor != null && cursor.moveToFirst()) {
    String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
    String photoUri = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_URI));

    // 输出联系人信息
    Log.d("Contact Info", "Name: " + displayName);
    Log.d("Contact Info", "Photo URI: " + photoUri);
}

// 关闭游标
if (cursor != null) {
    cursor.close();
}
