how do i get value from listview

Question

I have a ListView with my sqlite data and i would like to click and display the value in another Activity.

Can anyone teach me how to do this?

Below is my code:

Cursor cursor = mydb.queueAll();
    startManagingCursor(cursor);

    String[] from = new String[] { myDbAdapter.ELDERLY_DATE_TIME };
    int[] to = new int[] { R.id.textView1 };

    SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this,
            R.layout.displayactivity, cursor, from, to);
    listContent.setAdapter(cursorAdapter);
    mydb.close();

    listContent.setOnItemClickListener(new OnItemClickListener() {

        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            // TODO Auto-generated method stub

        }

    });

Thanks in advance :)

Where do you want to display the information? In another Activity, a popup window, a Toast, etc? **Also** exactly what information do you want to display? — Sam, Aug 02 '12 at 17:58
actually i just want to get the value so that i can past the value to another activity through intent — daek, Aug 02 '12 at 18:00
Why do you have another `Activity` for showing the value chosen? — prolink007, Aug 02 '12 at 18:14

You do not have to "pass" the value to another Activity. Inside your other Activity you just query for the correct value that was selected in your ListView.

actually i going to use the value to get other information from sqlite database and display it on the activity – daek Aug 02 '12 at 18:16
You need to pass some identification to the other `Activity` that identifies which item in the `ListView` was selected, with `Intents`. And then the other `Activity` would query the `sqlite` table for the value. But if you could explain why you need to pass this to another `Intent`, there might be a better way to do this in general. – prolink007 Aug 02 '12 at 18:18

Here are a couple references that talk about passing data to another `Activity` with `Intents`: http://stackoverflow.com/questions/2091465/how-do-i-pass-data-between-activities-in-android http://stackoverflow.com/questions/2736389/how-to-pass-object-from-one-activity-to-another-in-android – prolink007 Aug 02 '12 at 18:24
i know how to pass value through intent. But i not too sure how to get value from my listview. – daek Aug 02 '12 at 18:31
`onClickListener` gives you a `position` of the `View` that was pressed. This is the item selected. Use that `position` to determine what item was pressed in your `Adapter` and then use that to determine the id you need to use in the other `Activity` to get it from the database. – prolink007 Aug 02 '12 at 18:35
