How do I change the textColor of all elements in the popup android counter?
I am working on an application that presents a user with two graphics. Each object is associated with a corresponding counter from which the user can select one of several attributes. Touching one counter deactivates the other (this is handled outside of spinner.setEnabled.)
The view contains a single search bar from which the user can control the range of values applied to the last selected attribute.
Color is one of the attributes. When the arrow moves, I can change the background color of the floating elements. I need to set the text color of all items to black for light background colors and white for all dark colors.
if ( pos == object.COLOR_INDEX) {
//change spinner Background and Text color
spinner.setBackgroundColor(Colors.BACKGROUND[objectCurrent.getParams(pos)]);
TextView v ; int ct ;
for(int i=0; i<(ct=spinner.getChildCount()); ++i) {
v= (TextView)spinner.getChildAt(i);
v.setTextColor(Colors.FOREGROUND[objectCurrent.getParams(pos)]);
}
ColorDrawable drawable=(ColorDrawable) spinner.getBackground() ;
spinner.setPopupBackgroundDrawable(drawable);
spinner.setSelection(0); spinner.setSelection(pos);
}
I haven't found a way to do this. Looping via spinner.getChildAt (i) only affects the currently displayed item, not those hidden in the popup.
Any suggestions would be appreciated.
This obviously does the trick:
Resources res=getResources();
final List<String> spinnerItems=new ArrayList<String>(Arrays.asList(res.getStringArray(R.array.spin_settings)));
ArrayAdapter<String> aa=new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,spinnerItems){
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
View v = super.getDropDownView(position, convertView,
parent);
((TextView) v).setTextColor(Colors.FOREGROUND[obj.getParams(param.COLOR_INDEX)]);
((TextView) v).setBackgroundColor(Colors.BACKGROUND[obj.getParams(param.COLOR_INDEX)]);
return v;
}
};
aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerLeft.setAdapter(aa);
spinnerRight.setAdapter(aa);
It seems that the getDropDownView event is raised for every item in the dropdown.
