Question

I have a spinner in my apps.
There are four items:-

item1

item2

item3

item4

I want to change background color of item1 and item4 only.

How can i set the background for these two items only.

Answer 1

Changing the element color

You will need to write your own custom Adapter to do this job. getView() will be the method you are most interested in. There are lots of examples of how to write your own custom Adapter.

Here is an example from Vogella that is really good.

Basically do exactly what he did, change the getView() to check what item it currently is and then set the back ground color for that particular element View. He checked to see what item it was and then set an image for his ImageView. You would do the same, except change the background of your TextView.

If you can not figure this out, let me know. I will post a very simple custom Adapter example with what you are looking for.

Changing the Spinner color

Use mySpinner.setBackgroundColor(int color).

And do a check to see what value is selected in the spinner and change the color depending on what value is currently there.

PsuedoCode

if(mySpinner's current value == (item1||item4)) {

    mySpinner.setBackgroundColor(red);

}
