When I clicked on Android on Item, the position was clearly marked as 0, but I sent the value to another class in the shared preferences mode, so when I read the value, it appears as -1.

 @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Cursor cursor = (Cursor) parent.getItemAtPosition(position);

            int myId = position;

            final int item_id = cursor.getInt(cursor.getColumnIndex(databaseHelper.USER_TABLE_COLUMN_ID));

            PreferencesUtil.setIntPreferences(ListViewActivity.this,"myId",myId);

 }

        public static void setIntPreferences(Context context, String key, int value) {
    SharedPreferences p = context.getSharedPreferences("pref", context.MODE_PRIVATE);
    SharedPreferences.Editor editor = p.edit();
    editor.putInt(key, value);
    editor.commit();
}

public static int getIntPreferences(Context context, String key) {
    SharedPreferences sp = context.getSharedPreferences("your_prefs", Activity.MODE_PRIVATE);
    int myIntValue = sp.getInt("your_int_key", -1);
    return myIntValue;
}

   int myId = PreferencesUtil.getIntPreferences(detailUserActivity.this,"myId");
   log.i("otherClass","myId = "myId);
