Changing the background color of a view in real-time.
- by Tarmon
Hey Everyone,
I am trying to implement a ListView that is composed of rows that contain a View on the left followed by a TextView to the right of that. I want to be able to change the background color of the first View based on it's position in the ListView. Below is what I have at this point but it doesn't seem to due anything.
public class Routes extends ListActivity {
String[] ROUTES;
TextView selection;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ROUTES = getResources().getStringArray(R.array.routes);
setContentView(R.layout.routes);
setListAdapter(new IconicAdapter());
selection=(TextView)findViewById(R.id.selection);
}
public void onListItemClick(ListView parent, View v, int position, long id) {
selection.setText(ROUTES[position]);
}
class IconicAdapter extends ArrayAdapter<String> {
IconicAdapter() {
super(Routes.this, R.layout.row, R.id.label, ROUTES);
}
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = getLayoutInflater();
View row = inflater.inflate(R.layout.row, parent, false);
TextView label = (TextView) row.findViewById(R.id.label);
label.setText(ROUTES[position]);
View icon = (View) row.findViewById(R.id.icon);
switch(position){
case 0:
icon.setBackgroundColor(R.color.Red);
break;
case 1:
icon.setBackgroundColor(R.color.Red);
break;
case 2:
icon.setBackgroundColor(R.color.Green);
break;
case 3:
icon.setBackgroundColor(R.color.Green);
break;
case 4:
icon.setBackgroundColor(R.color.Blue);
break;
case 5:
icon.setBackgroundColor(R.color.Blue);
break;
case 6:
icon.setBackgroundColor(R.color.Gray);
break;
case 7:
icon.setBackgroundColor(R.color.Yellow);
break;
case 8:
icon.setBackgroundColor(R.color.Brown);
break;
case 9:
icon.setBackgroundColor(R.color.Brown);
break;
case 10:
icon.setBackgroundColor(R.color.Brown);
break;
case 11:
icon.setBackgroundColor(R.color.Purple);
break;
case 12:
icon.setBackgroundColor(R.color.Red);
break;
case 13:
icon.setBackgroundColor(R.color.Gold);
break;
case 14:
icon.setBackgroundColor(R.color.Orange);
break;
}
return(row);
}
}
Any input is appreciated and if you have any questions don't hesitate to ask!
Thanks,
Rob
