setBackgroundResource() to spinner in Android 5 not works

Question

strange things happen. I am trying to set background to spinner. spinner.setBackgroundResource(R.drawable.spinner_error); This code works perfect in lower Android versions than 5, but in lollipop, this code do nothing. I tried to change color spinner.setBackgroundColor(Color.RED); but it only makes spinner invisible. So, how to change spinner color/resource ?

EDIT: Adapter code:

public class FuelStoragesAdapter extends ArrayAdapter<ModelFuelStorage> {

    private Context context;
    private List<ModelFuelStorage> fuelStorages;
    private boolean addAdditionalItems = false;

    public FuelStoragesAdapter(Context context, List<ModelFuelStorage> fuelStorages, boolean addAdditionalItems) {
         super(context, android.R.layout.simple_spinner_item, fuelStorages);
        this.context = context;
        this.fuelStorages = fuelStorages;
        this.addAdditionalItems = addAdditionalItems;
        setDropDownViewResource(R.layout.spinner_dropdown_layout);
        if (addAdditionalItems)
            addAdditionalItems();
    }

    public void addStorage(ModelFuelStorage fuelStorage) {
        insert(fuelStorage, getCount() - 1);
        notifyDataSetChanged();
    }

    public void addAdditionalItems() {
         fuelStorages.add(new ModelFuelStorage(0, context.getString(R.string.add_new_storage), 0));
         fuelStorages.add(new ModelFuelStorage(-1, context.getString(R.string.choose_storage), 0));
    }


    @Override
    public int getCount() {

        if (addAdditionalItems)
            return super.getCount() - 1; // you dont display last item. It is used as hint.
        else
            return super.getCount();
    }

    public int getPosition(int storageId){
        for(ModelFuelStorage storage : fuelStorages)
            if(storage.getId() == storageId)
                return  fuelStorages.indexOf(storage);
        return 0;
    }

}

The solution for this is to add this code when creating the spinner dynamically:

spinner.setPopupBackgroundResource(R.drawable.spinner);

and to create spinner.xml under Drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#ffffff" />
</shape>

This solution require API level of 16 and above.

Give try to this code:

spinner.setBackgroundColor(Color.parseColor("#FFFF00"));

"#FFFF00" instead of this use any other color code.This is working for me in Android v5.

In Android Lollipop Version you have to implement code for kitkat version and lollipop version separately , please do this code for change background of spinner. its example of image background changes of images.

        if (Build.VERSION.SDK_INT => Build.VERSION_CODES.KitKat) 
                        {
                            //for Lollipop Vession

//set color in this block which you want 
spinner.setBackgroundDrawable(Color.RED);
                        }
                        else
                        {
    // for Kikat Version

spinner.setBackgroundResource(xyz);
//set color in this block which you want 
                        }

i hope it helps you, if it is useful code for then please mark me .. Thanx.. :)

Have you set any adapter to your spinner? if not use something like this: Place in your activity's onCreate() method:

//Get your spinner
spinner = (Spinner)findViewById(R.id.spinner);

// Defined Array values to show in ListView
String[] values = new String[] { "item1",
            "item2",
            "item3"};

//Construct the ArrayAdapter
ArrayAdapter<String> spinneradapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_dropdown_item, android.R.id.text1, values);

 //Set the adapter to the corresponding spinner
spinner.setAdapter(spinneradapter);

 //Change background color to "RED"
 spinner.setBackgroundColor(Color.parseColor("#FFFF0000"));

Tested, Works with android 5.0.1

Hope this will help you out
