Answer 1

Well what you do is add lvTrainTime to the scr ScrollView than use it as a content view for the dialog. Maybe what you want to do is setContentView(scr);? If you do it this way scr will play the role of a container of the view. So basically you need to set the container as a content view.

EDIT - clarifications:

What I meant was that in your loadAutocomplete1 method you create a ScrollView scr = new ScrollView(this);. Later in the same method, after the loop, you add a view to that scroll view - scr.addView(lvTrainTime); and then set the content view of the dialog to be the mentioned view - dialog.setContentView(lvTrainTime);. You cant do that because scr and dialog are different controls and one view (lvTrainTime) can't have two parents. So, instead of setting the content view to be that view - lvTrainTime - I meant that you should set it's parent(container) as a content view. By the time I answered I thought it was scr that should be set as content view but I just saw that you actually put the scr in a tableLayout - tablelayout.addView(scr, new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, 50));. So your current situation is that lvTrainTime is inside scr and scr is inside tableLayout. So try dialog.setContentView(tableLayout); instead. In addition I am not sure what happens when you set the content view of the dialog twice so maybe you should try without dialog.setContentView(R.layout.traintimings_dialog); too.
