选择一个电话号码到自己的应用程序中

用下面的方法虽然可以得到一个电话号码,但不是自己选择的电话号码,每次都返回那个号码.求大神帮忙看看要怎么才能读取到自己所选的号码...先谢过了`enter code here @Override

public void onActivityResult(int reqCode, int resultCode, Intent data) {
 super.onActivityResult(reqCode, resultCode, data);
 ContentResolver cr = getContentResolver();
 //取得电话本中开始一项的光标
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
 //向下移动光标
while(cursor.moveToNext())
 {
 //取得联系人名字
int nameFieldColumnIndex = cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME);
 String contact = cursor.getString(nameFieldColumnIndex);
 //取得电话号码
String ContactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
 //Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId, null, null);
 Cursor phone = cr.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);
 if(phone.moveToFirst())
 {
 String PhoneNumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
 string = PhoneNumber ;
 cursor.close();
 mNumber.setText(string);
 break;
 }
 }
