当我通过电话查看我的联系人时，我也看到了whatsapp帐户的whatsapp号码。我想要做的是过滤我的联系人列表并显示与whatsapp同步的号码。我成功检索了所有联系人ID ，数字和帐户与它相关但不显示whatsappaccount.Only相关的谷歌帐户正在显示。有没有办法从本地电话本身获得whatsapp联系？我使用了以下代码：
ContentResolver cr1 = getContentResolver();
Cursor cur = cr1.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 = cr1.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);
while (pCur.moveToNext())
{
//phoneContactList.add(name);
Log.i("Contact List", name);
Log.i("Contact List", id);
getContactAccount(id,cr1);
}
pCur.close();
}
}
}
public void getContactAccount（String id，ContentResolver contentResolver）{
Cursor cursor = null;
try {
cursor = contentResolver.query(ContactsContract.RawContacts.CONTENT_URI,
new String[]{ContactsContract.RawContacts.ACCOUNT_NAME, ContactsContract.RawContacts.ACCOUNT_TYPE},
ContactsContract.RawContacts.CONTACT_ID +"=?",
new String[]{String.valueOf(id)},
null);
if (cursor != null && cursor.getCount() >0)
{
cursor.moveToFirst();
System.out.println("Account name is"+cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.ACCOUNT_NAME)));
System.out.println("Account type is"+cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.ACCOUNT_TYPE)));
cursor.close();
}
} catch (Exception e)
{
System.out.println(""+this.getClass().getName()+","+ e.getMessage());
} finally
{
cursor.close();
}
}
The MIME type for whatsapp is: "vnd.android.cursor.item/vnd.com.whatsapp.profile"
使用以下代码：

}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {

// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}

使用以下代码从电话簿获取WhatsApp联系人以及相关的WhatsApp号码：
private void displayWhatsAppContacts() {
final String[] projection = {
ContactsContract.Data.CONTACT_ID,
ContactsContract.Data.DISPLAY_NAME,
ContactsContract.Data.MIMETYPE,
"account_type",
ContactsContract.Data.DATA3,
};
final String selection = ContactsContract.Data.MIMETYPE + " =? and account_type=?";
final String[] selectionArgs = {
"vnd.android.cursor.item/vnd.com.whatsapp.profile",
"com.whatsapp"
};
ContentResolver cr = getContentResolver();
Cursor c = cr.query(
ContactsContract.Data.CONTENT_URI,
projection,
selection,
selectionArgs,
null);
while (c.moveToNext()) {
String id = c.getString(c.getColumnIndex(ContactsContract.Data.CONTACT_ID));
String number = c.getString(c.getColumnIndex(ContactsContract.Data.DATA3));
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Log.v("WhatsApp", "name " +name + " - number - "+number);
}
Log.v("WhatsApp", "Total WhatsApp Contacts: " + c.getCount());
c.close();
}
