Android 内容解析器 Returns 在手机中激活的所有帐户否

Question

在尝试使用以下代码从 android 检索联系人列表时，它 returns 多个帐户，如 google/gmail、whatsapp 和 soma（激活的帐户数量取决于数量内容解析器 returns 用于那么多联系人副本！）。请帮我删除它。

 cursor1=getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI ,null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME +" ASC");              
 startManagingCursor(cursor1);
String[] from = {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone._ID,}; 
  int[] to = {android.R.id.text1, android.R.id.text2}; 
listadapter = new SimpleCursorAdapter(getBaseContext(), android.R.layout.simple_list_item_2, cursor1, from, to);        
 setListAdapter(listadapter);

Simpy 尝试下面的代码，它有更多的验证并检查它是否有 phone 号码。但是你的andorid设备的联系人要安排好。

   private void displayContacts() {

      ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
                null, null, null, null);
        if (cur.getCount() > 0) {
            while (cur.moveToNext()) {
                  String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
                  String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                  if (Integer.parseInt(cur.getString(
                        cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                     Cursor pCur = cr.query(
                               ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                               null,
                               ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
                               new String[]{id}, null);
                     while (pCur.moveToNext()) {
                         String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                         Toast.makeText(NativeContentProvider.this, "Name: " + name + ", Phone No: " + phoneNo, Toast.LENGTH_SHORT).show();
                     }
                    pCur.close();
                }
            }
        }
    }

您还可以在此处对帐户进行一些过滤，例如使用下面的代码过滤掉 what's app 帐户，该代码从 phone 联系人中获取 what's app 联系人：

Cursor c = getContentResolver().query(
        RawContacts.CONTENT_URI,
        new String[] { RawContacts.CONTACT_ID, RawContacts.DISPLAY_NAME_PRIMARY },
        RawContacts.ACCOUNT_TYPE + "= ?",
        new String[] { "com.whatsapp" },
        null);

ArrayList<String> myWhatsappContacts = new ArrayList<String>();
int contactNameColumn = c.getColumnIndex(RawContacts.DISPLAY_NAME_PRIMARY);
while (c.moveToNext())
{
    // You can also read RawContacts.CONTACT_ID to read the
    // ContactsContract.Contacts table or any of the other related ones.
    myWhatsappContacts.add(c.getString(contactNameColumn));
}
