我如何获得联系人ID和联系人组?我使用了以下代码,它给了我姓名和电话任何所有其他信息,但不是id或组
public void ExportContacts() {
vCard = new ArrayList<String>();
cursor = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
int ss = cursor.getCount();
if(cursor!=null&&cursor.getCount()>0)
{
cursor.moveToFirst();
for(int i =0;i<cursor.getCount();i++)
{
get(cursor);
Log.d("TAG", "Contact "+(i+1)+"VcF String is"+vCard.get(i));
cursor.moveToNext();
}
}
else
{
Log.d("TAG", "No Contacts in Your Phone");
}
}
public void get(Cursor cursor)
{
//cursor.moveToFirst();
String lookupKey = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
AssetFileDescriptor fd;
try {
String _id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
fd = mContext.getContentResolver().openAssetFileDescriptor(uri, "_ID");
FileInputStream fis = fd.createInputStream();
byte[] buf = new byte[(int) fd.getDeclaredLength()];
fis.read(buf);
String vcardstring= new String(buf);
vCard.add(vcardstring);
String storage_path = Environment.getExternalStorageDirectory().toString() + File.separator + vfile;
FileOutputStream mFileOutputStream = new FileOutputStream(storage_path, true);
mFileOutputStream.write(vcardstring.toString().getBytes());
} catch (Exception e1)
{
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
我想将ID和组名放在我在文件中写入的vCard中。任何人都可以帮忙吗?
