Question

I’m having an issue with the Droid X phones where users say that the font color turns out to be white in the spinner, making it invisible unless the users highlight the items. No other phones seem to have this problem. I was going to try to force the font to be black to see if that helps. How can I do that?

Here’s how I’m currently populating the spinner. It seems like the simple_spinner_item is broken on Droid X’s.

String spin_arry[] = new String[str_vec.size()];
str_vec.copyInto(spin_arry);
ArrayAdapter adapter =
    new ArrayAdapter(this,android.R.layout.simple_spinner_item, spin_arry);

Answer 1

I’m going to use Spinner project sample from Android SDK for next code examples.

Code:

First, you need to create you custom adapter which will intercept the creation of views in drop down list:

static class CustomArrayAdapter<T> extends ArrayAdapter<T>
{
    public CustomArrayAdapter(Context ctx, T [] objects)
    {
        super(ctx, android.R.layout.simple_spinner_item, objects);
    }

    //other constructors

    @Override
    public View getDropDownView(int position, View convertView, ViewGroup parent)
    {
        View view = super.getView(position, convertView, parent);

        //we know that simple_spinner_item has android.R.id.text1 TextView:         

        /* if(isDroidX) {*/
            TextView text = (TextView)view.findViewById(android.R.id.text1);
            text.setTextColor(Color.RED);//choose your color :)         
        /*}*/

        return view;

    }
}

Then you create adapter in your code like this:

 String [] spin_arry = getResources().getStringArray(R.array.Planets);        
 this.mAdapter = new CustomArrayAdapter<CharSequence>(this, spin_arry);

Explanation:

Because CustomArrayAdapter knows that we use android’s built-in layout resource, it also knows that text will be placed in TextView with id android.R.id.text1. That’s why it can intercept the creation of views in drop down list and change text color to whatever color is needed.
