Android-如何从通话记录中获取联系人？

Question

我正在尝试从通话记录中获取联系人。我可以使用以下代码从主要联​​系人获取联系电话：

    public void getContacts(View view) {

    Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
    startActivityForResult(intentContact, 0);

}

public void onActivityResult(int requestCode, int resultCode, Intent intent)
{

    if (requestCode == 0)
    {
        try {
        to.setText(getContactInfo(intent));
        } catch(NullPointerException e) {
                 // Do nothing ;)
        }

    }

}
protected String getContactInfo(Intent intent)
{
    String phoneNumber = to.getText().toString();
    Cursor cursor =  managedQuery(intent.getData(), null, null, null, null);
    while (cursor.moveToNext())
    {
        String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
       String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
      if(phoneNumber.endsWith(">"))
          phoneNumber += ", "+name;
        else
         phoneNumber += name;
        String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

        if ( hasPhone.equalsIgnoreCase("1"))
            hasPhone = "true";
        else
            hasPhone = "false" ;

        if (Boolean.parseBoolean(hasPhone))


        {
            Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
            while (phones.moveToNext())
            {   phoneNumber = phoneNumber + " <" + phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))+">";


               }
            phones.close();
        }


    }
    cursor.close();
    return phoneNumber;
}

它的作用是，当我们单击“联系人”按钮时，它将打开一个包含所有联系人的列表，用户可以选择任何联系人，并且所选联系人将添加到“收件人”字段中。我想做完全相同的事情，但是我不想显示所有联系人，而是只显示最近使用过的那些（呼叫记录）进行选择的联系人。

如果您还可以告诉如何与组一起执行此操作，那也很好。

我使用自己的版本进行了此操作。我使用了一个对话框，并将光标移到了通话记录。这是函数：

public void getCallLog() {

    String[] callLogFields = { android.provider.CallLog.Calls._ID,
            android.provider.CallLog.Calls.NUMBER,
            android.provider.CallLog.Calls.CACHED_NAME /* im not using the name but you can*/};
    String viaOrder = android.provider.CallLog.Calls.DATE + " DESC";
    String WHERE = android.provider.CallLog.Calls.NUMBER + " >0"; /*filter out private/unknown numbers */

    final Cursor callLog_cursor = getActivity().getContentResolver().query(
            android.provider.CallLog.Calls.CONTENT_URI, callLogFields,
            WHERE, null, viaOrder);

    AlertDialog.Builder myversionOfCallLog = new AlertDialog.Builder(
            getActivity());

    android.content.DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialogInterface, int item) {
            callLog_cursor.moveToPosition(item);

            Log.v("number", callLog_cursor.getString(callLog_cursor
                    .getColumnIndex(android.provider.CallLog.Calls.NUMBER)));

            callLog_cursor.close();

        }
    };
    myversionOfCallLog.setCursor(callLog_cursor, listener,
            android.provider.CallLog.Calls.NUMBER);
    myversionOfCallLog.setTitle("Choose from Call Log");
    myversionOfCallLog.create().show();
}
