微调框默认文本颜色为白色？

Question

I would like to change the color of the default value of my spinner.

This value is white for no reason, how can I fix the text color of this default value to black?

Illustration:

ArrayAdapter<String> adapter;
List<String> list;

list=new ArrayList<String>();
list.add("0.01");
list.add("0.10");
list.add("1.00");
list.add("10.0");
list.add("100");
adapter= new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_item,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner_pas.setAdapter(adapter);
spinner_pas.setSelection(2);

Answer 1

Add the below line into the xml - android.R.layout.simple_spinner_item

 android:background="@color/black"
 android:textColor="@color/white"

Answer 2

Create a custom theme for Spinner like this

<style name="CustomSpinnerTheme" 
  parent="Base.Widget.AppCompat.DropDownItem.Spinner">
    <item name="android:textColor">#000000</item>
    <item name="android:background">#ffffff</item>
</style>

and apply it here

 adapter= new ArrayAdapter<String>(getApplicationContext(), 
 android.R.style.CustomSpinnerTheme,list);
