Question

我正在开发一个应用程序，其中需要查找联系人组的性质，这意味着它是谷歌组，电话组还是SIM组。怎么找到它。请建议我怎么做。提前谢谢。

Answer 1

以下代码打印联系人姓名和类型。我没有优化它，它会打印多个记录，但我想你会知道该怎么做。

package com.example.android.contactmanager;
import android.app.Activity;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.RawContacts;
import android.util.Log;

public final class ContactManager extends Activity{

/**
 * Called when the activity is first created. Responsible for initializing the UI.
 */
@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    printContactList();
}

/**
 * Print contact data in logcat.
 * SIM : Account_Type = com.anddroid.contacts.sim
 * Phone : Depends on the manufacturer e.g For HTC : Account_Type = com.htc.android.pcsc
 * Google : Account_Type = com.google
 */
private void printContactList() {
    Cursor cursor = getContacts();
    cursor.moveToFirst();
    while (cursor.isAfterLast() == false) {
        Log.d("Display_Name", cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME)));
        Log.d("Account_Type", cursor.getString(cursor.getColumnIndex(RawContacts.ACCOUNT_TYPE)));
        cursor.moveToNext();

    }
}

/**
 * Obtains the contact list for the currently selected account.
 *
 * @return A cursor for for accessing the contact list.
 */
private Cursor getContacts()
{
    // Run query
    Uri uri = ContactsContract.Data.CONTENT_URI;
    String[] projection = new String[] {
            ContactsContract.Contacts._ID,
            ContactsContract.Contacts.DISPLAY_NAME,
            RawContacts.ACCOUNT_TYPE
    };
    String[] selectionArgs = null;
    String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

    return managedQuery(uri, projection, null, selectionArgs, sortOrder);
}
}

我有同样的问题，你提到我解决了这个问题

ArrayList<GroupNameDetails> stateList = new ArrayList<GroupNameDetails>();
      final String[] GROUP_PROJECTION = new String[] 
                {
                    ContactsContract.Groups._ID, ContactsContract.Groups.TITLE,   ContactsContract.Groups.ACCOUNT_TYPE//this line will do the trick
                };
            Cursor cursor = getContentResolver().query(ContactsContract.Groups.CONTENT_URI, GROUP_PROJECTION, null,
                    null, ContactsContract.Groups.TITLE);
            while (cursor.moveToNext()) {
                String accountname=cursor.getString(cursor.getColumnIndex(ContactsContract.Groups.ACCOUNT_TYPE));
                Toast.makeText(getBaseContext(), accountname, Toast.LENGTH_LONG).show();// and it will display group type
                String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Groups._ID));
                Log.v("Test", id);
                //ContactsContract.Groups.ACCOUNT_NAME

                String gTitle = (cursor.getString(cursor.getColumnIndex(ContactsContract.Groups.TITLE)));
                if(favGroupName.contains(gTitle)==false)
                {
                favGroupId.add(id);
                favGroupName.add(gTitle);

                GroupNameDetails _states = new GroupNameDetails(Long.parseLong(id),gTitle, false);
                stateList.add(_states);
                }
                Log.v("Test", gTitle);
                if (gTitle.contains("Favorite_")) {
                    gTitle = "Favorites";

                }

            }

查找联系人组的帐户性质？
