Individual backround color for spinner items

I would like to color each item´s backround of the spinner individual.
The items are set with this code:

Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
            R.array.duesentypen, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

The hex values are stored in an array. Whereas the index count refers to the item count. E.g.:

String[] hex = {"#886da8", "#ffc3cf","#ef9b00", "#2bb430", "#f7dc01", "#bc65a2", "#487ebf","#e00124","#b36634","#949494", "#ffffff","#000000","#4bbbd0", "#8b6d9f", "#8ccff4"};
//color for the first spinner item: hex[0]
//color for the second spinner item: hex[1]

How could I do that in the best way?

Try to change color according to Position.

final List<String> plantsList = new ArrayList<>(Arrays.asList(plants));

        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
            R.array.duesentypen, android.R.layout.simple_spinner_item){
            @Override
            public View getDropDownView(int position, View convertView,
                                        ViewGroup parent) {
                View view = super.getDropDownView(position, convertView, parent);
                TextView tv = (TextView) view;
               
        switch(position) {
             case 0:
                tv.setTextColor(Color.parseColor("#FF7C7967"));
             case 1:
                tv.setTextColor(Color.parseColor("#FF7C7967"));
                   }
                
                return view;
            }
        };

        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter);

You need to create a custom Spinner adapter and override getView() to set the color and text of each item.

Here I am wrapping colors around the array of colors using the modulus operator (%) in order to avoid IndexOutOfBoundsExecption if the items are greater than the available colors.

The custom adapter

public class ColorAdapter extends BaseAdapter {
private ArrayList<Integer> mColors;
private String[] mItems;
ColorAdapter2(String[] items) {
mItems = items;
String[] hex = {"#886da8", "#ffc3cf", "#ef9b00", "#2bb430", "#f7dc01", "#bc65a2", "#487ebf", "#e00124", "#b36634", "#949494", "#ffffff", "#000000", "#4bbbd0", "#8b6d9f", "#8ccff4"};
mColors = new ArrayList<>();
for (String color : hex) {
mColors.add(Color.parseColor(color));
}
}
@Override
public int getCount() {
return mItems.length;
}
@Override
public Object getItem(int args) {
return mColors.get(args);
}
@Override
public long getItemId(int args) {
return args;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
convertView = inflater.inflate(android.R.layout.simple_spinner_dropdown_item, null);
holder = new ViewHolder();
holder.textView = convertView.findViewById(android.R.id.text1);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.textView.setBackgroundColor(mColors.get(position % mColors.size()));
holder.textView.setText( mItems[position]);
return convertView;
}
/* Return spinner text of the item at particular position*/
public String getItemAtPosition(int position) {
if (position > -1 && position < mItems.length)
return mItems[position];
else
return null;
}
static class ViewHolder {
TextView textView;
}
}

Usage

Spinner spinner = findViewById(R.id.spinner);
spinner.setAdapter(new ColorAdapter(getResources().getStringArray(R.array.myItems)));

strings.xml

<resources>
<string name="app_name">Color Activity</string>
<string-array name="myItems">
<item>item1</item>
<item>item2</item>
<item>item3</item>
<item>item4</item>
<item>item5</item>
</string-array>
</resources>

Result

Now as we created a custom adapter, then you have to customize any related data and you can't rely on the API of the default Spinner adapter; so I've added a getItemAtPosition() method above at the custom adapter that takes a position, and returns the text of this item.

Usage

String item = ((ColorAdapter)spinner.getAdapter()).getItemAtPosition(position));

And you can get it whenever an item is selected:

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Log.d(TAG, "onItemSelected: " + 
((ColorAdapter)spinner.getAdapter()).getItemAtPosition(position));
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
