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.
