CursorAdapter onitemClick of listview

Question

Hi I am developing an android app with CursorAdapter for loading the listview. onItemClick of the listview item, I am trying to start a dialogue activity.

    adapter = new ConversationAdapter(MainActivity.this, cursor);
    list.setAdapter(adapter);


    list.setOnItemClickListener(new OnItemClickListener() 
    {
        public void onItemClick(AdapterView<?> parent, View view, int position, long arg3) 
        {
            Cursor cur = (Cursor) adapter.getItem(position);
            cur.moveToPosition(position);
            id = cur.getString(cur.getColumnIndexOrThrow("_id"));

            Intent intent = new Intent(MainActivity.this, DialogueActivity.class);
            Bundle bundle = new Bundle();
            bundle.putString ("id", id);
            intent.putExtras(bundle);

            startActivity(intent);
        }
    });

I am using only the startActivity without a finish(). The problem is the listview which is to be displayed at back disappears and there is just a black screen. Not sure what I need to do so that listview is displayed in background of DialogueActivity.

onItemClick of the listview item is displayed as below

Try this codes..

getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

before setContentView(R.layout.activity); in DialogueActivity.class
