Question

I have an ArrayList I am sending item onItemClick On another activity from this:-

list.setOnItemClickListener(new OnItemClickListener() {

        public void onItemClick(AdapterView<?> arg0, View arg1,
                int position, long arg3) {
            Intent i = new Intent(MessageEmail.this, MessageByMessage.class);
            i.putExtra("msg_title", unreadMsgList.get(position).address);
            i.putExtra("full_msg",
                    unreadMsgList.get(position).unreadMessage);
            i.putExtra("pos", position);
            startActivity(i);
            finish();

        }
    });

& get On another activity & set on text from this:-

title=getIntent().getExtras().getString("msg_title");
    message=getIntent().getExtras().getString("full_msg");
    position=getIntent().getExtras().getInt("pos");
    title_txt.setText(title);
    msg_txt.setText(message);

Now Problem is that I have a delete button in this activity. I want to delete item on Button click & will switch on my first activity Where List should be refresh.
Thanks in advance!

Use StartActivityForResult(yourIntent,YOUR_REQUEST_CODE); and on the onActivityResult

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode)
    {
        case YOUR_REQUEST_CODE:
            if(resultCode == RESULT_OK)
                yourArrayList.remove(theItemClicked);
                yourListview.notifySetDataChanged();
            break;

        default:
            break;
    }

}

in the otherActivity simply set some Result in an INTENT and finish() that Activity on Delete Button’s OnClick Event.
