    String [] keluar = { data.k_nama, data.m_chiperteks, data.kel_waktu };
    int[] k = { R.id.tNama, R.id.tChiper, R.id.tWaktu };
    cursor = data.DataPesanKeluar();
    SimpleCursorAdapter keluarAdapter = new SimpleCursorAdapter( this, R.layout.baris_keluar, cursor, keluar, k ); //this line my error

                nama = cursor.getString(cursor.getColumnIndex(data.k_nama));
                chiperteks = cursor.getString(cursor.getColumnIndex(data.m_chiperteks));

            isiPesanKeluar.putExtra("idkeluar", idkeluar);
            isiPesanKeluar.putExtra("nama", nama);

            + kel_id + " AS _id,"
            + e_chiperteks + ","
            + k_nama + ","
            + kel_waktu +
            " FROM " + tbPesan + " INNER JOIN " + tbPesanKeluar +
            " ON "  + tbPesan + "." + p_idpesan + "=" + tbPesanKeluar + "." + kel_idpesan +

    return c;
}

Instead of

Cursor listCursor = (Cursor) arg0.getItemAtPosition(arg2);
        if(listCursor.moveToFirst())

Use

@Override
    public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3) {
            if(cursor.moveToPosition(arg2)) {
            idkeluar = cursor.getString(cursor.getColumnIndex("_id"));
            nama = cursor.getString(cursor.getColumnIndex(data.k_nama));
            chiperteks = cursor.getString(cursor.getColumnIndex(data.m_chiperteks));
            waktu = cursor.getString(cursor.getColumnIndex(data.kel_waktu));
        }

Did you change all your listCursor to cursor? – Hoan Nguyen May 06 '13 at 07:58
post DataPesanKeluar() method – Hoan Nguyen May 06 '13 at 08:08
i tried but my listview didn't respon when i click the list :( – androidDev May 06 '13 at 08:17
So now there is no more error but the list does not respond on click? – Hoan Nguyen May 06 '13 at 08:19
Post your baris_keluar layout. – Hoan Nguyen May 06 '13 at 08:24
In your listview layout add android:choiceMode="singleChoice" to your ListView – Hoan Nguyen May 06 '13 at 08:34
I think you should post another question like "ListView onItemClickListener does not fired" and post the complete code for onItemClickListener and I will continue to try to help but you would get other people having this problem before that may help you better than I. – Hoan Nguyen May 06 '13 at 08:48
Did you call startActivity(isiPesanKeluar) after the line isiPesanKeluar.putExtra("waktu", waktu);? – Hoan Nguyen May 06 '13 at 08:57
thanks for ur answer, it's really useful. and i'm sorry if i unaccurate my code clearly :) – androidDev May 06 '13 at 09:24
If your list still did not respond on click, put a log in onItemClick like Log.d("ActivityName", "onItemclick") and see if onItemClick being called. And post the question as I suggested. If nobody answer, leave a message here with the link to your post and I will take a look tomorrow as I get really late here and I am going to sleep. – Hoan Nguyen May 06 '13 at 09:29
You should unaccept my answer in your post at http://stackoverflow.com/questions/16382416/caused-by-java-lang-illegalargumentexception-column-id-does-not-exist as Yoann answer correctly a few second before my answer. An upvote is enough for me, I did upvote the Yoann answer after I wrote the answer and saw Yoann answer. – Hoan Nguyen May 06 '13 at 09:36
my list is working now, thanks to you :D if i had error again i'll contact you :D – androidDev May 06 '13 at 10:35
can u help me in my post? http://stackoverflow.com/questions/16474958/my-sms-receiver-cant-accept-new-sms – androidDev May 10 '13 at 04:33

To retrieve the item at position, using the a CursorAdapter, you can simple call Adapter.getItemAtPosition(position) casting the return object to Cursor. Afterwards you do not need to move it again. The returned value is what you have clicked:

@Override
public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3) {
     Cursor tmpCursor = arg0.getItemAtPosition(arg2);
     // use the cursor to retrieve the content of the columns
}

    eventlist.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View v, int arg2, long arg3) {
            TextView eventname = (TextView) v.findViewById(android.R.id.text1);
            Toast.makeText(v.getContext(),"eventname is" + eventname.getText().toString(),Toast.LENGTH_LONG).show();
        }
    });
