android 获取联系人

public void getContact(){//获得所有的联系人   Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);   //循环遍历   if (cur.moveToFirst()) {int idColumn  = cur.getColumnIndex(ContactsContract.Contacts._ID);   int displayNameColumn = cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);do {   //获得联系人的ID号   String contactId = cur.getString(idColumn);//获得联系人姓名   String disPlayName = cur.getString(displayNameColumn);   //查看该联系人有多少个电话号码。如果没有这返回值为0   int phoneCount = cur.getInt(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));   if(phoneCount>0){   //获得联系人的电话号码      Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,   ContactsContract.CommonDataKinds.Phone.CONTACT_ID   + " = " + contactId, null, null);      if(phones.moveToFirst()){   do{   //遍历所有的电话号码   String phoneNumber= phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));     System.out.println(phoneNumber);      }while(phones.moveToNext());   }}   } while (cur.moveToNext());}   }

在联系人的电话号码中有很多种，如果只想获得手机号码

Cursor phones = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,           ContactsContract.CommonDataKinds.Phone.CONTACT_ID            + " = " + contactId+" and "+ ContactsContract.CommonDataKinds.Phone.TYPE+"="+ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE, null, null);
