请帮我这个问题谢谢

Answer 1

随着你的清单中READ_CONTACTS许可，您可以得到同步给出的帐户类型的联系人。对于WhatsApp的是"com.whatsapp"。所以：

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));
}

Answer 2

myWhatsappContacts的ArrayList将包含所有的电话号码存在于你的WhatsApp应用。

Cursor cursor = getContentResolver().query(ContactsContract.Data.CONTENT_URI 
                  ,new String[] {ContactsContract.Data._ID
                               ,ContactsContract.Data.DISPLAY_NAME
                               ,ContactsContract.CommonDataKinds.Phone.NUMBER 
                               ,ContactsContract.CommonDataKinds.Phone.TYPE}
                  ,ContactsContract.Data.MIMETYPE + "='" + ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE
                  + "' AND " + ContactsContract.RawContacts.ACCOUNT_TYPE + "= ?"
                  ,new String[] { "com.whatsapp" }
                  , null);

    while (cursor.moveToNext())
    {

        myWhatsappContacts.add(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))); 

    }

是System.out.print（ “名称： ”+ cursor.getString（contactNameColumn）+“ \ n ”+“ 电话号码” + cursor.getString（cursor.getColumnIndex（ContactsContract.CommonDataKinds.Phone.NUMBER）））;
