简单而干脆……

private OnItemSelectedListener OnCatSpinnerCL = new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {

       ((TextView) parent.getChildAt(0)).setTextColor(Color.BLUE);
       ((TextView) parent.getChildAt(0)).setTextSize(5);

    }

    public void onNothingSelected(AdapterView<?> parent) {

    }
};

对于那些想要改变DrowDownIcon颜色的人 你可以这样用

spinner.getBackground().setColorFilter(Color.parseColor("#ffffff"), PorterDuff.Mode.SRC_ATOP);

为了防止滞后，你不仅需要在onItemSelected监听器中设置文本属性，还需要在Activity的onCreate方法中设置文本属性(但这有点棘手)。

具体来说，你需要在设置适配器后把这个放在onCreate中:

spinner.setSelection(0, true);
View v = spinner.getSelectedView();
((TextView)v).setTextColor(backgroundColor);

然后把这个放到onItemSelected中:

((TextView) view).setTextColor(backgroundColor);

下面是一个完整的例子:

@Override  
protected void onCreate(Bundle savedInstanceState)
{  
    Spinner spinner = (Spinner) findViewById(R.id.spinner); 

    //Set the choices on the spinner by setting the adapter.  
    spinner.setAdapter(new SpinnerAdapter(toolbar.getContext(), new String[]{"Overview", "Story", "Specifications", "Poll", "Video"}, accentColor, backgroundColor));

    //Set the text color of the Spinner's selected view (not a drop down list view) 
    spinner.setSelection(0, true);
    View v = spinner.getSelectedView();
    ((TextView)v).setTextColor(backgroundColor);

    //Set the listener for when each option is clicked.  
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
    {  

        @Override  
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
        {  
           //Change the selected item's text color  
           ((TextView) view).setTextColor(backgroundColor);
        }  

        @Override  
        public void onNothingSelected(AdapterView<?> parent)
        {  
        }  
    });  

}  

要了解更多细节，请参见我的问题。

可以通过重写getView方法更改文本颜色，如下所示:

 new ArrayAdapter<String>(getContext(), android.R.layout.simple_spinner_dropdown_item, list()){
                @Override
                public View getView(int position, View convertView, @NonNull ViewGroup parent) {
                    View view = super.getView(position, convertView, parent);
                    //change the color to which ever you want                    
                    ((CheckedTextView) view).setTextColor(Color.RED);
                    //change the size to which ever you want                    
                    ((CheckedTextView) view).setTextSize(5);
                    //for using sp values use setTextSize(TypedValue.COMPLEX_UNIT_SP, 16);
                    return view;
                }
    }

更改微调文本的颜色:

 public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            ((TextView) parent.getChildAt(0)).setTextColor(Color.WHITE);}

首先，我们必须为textview创建简单的xml资源文件，如下所示:

<?xml version="1.0" encoding="utf-8"?>

 <TextView  
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:gravity="left"  
    android:textColor="#FF0000"         
    android:padding="5dip"
    />   

然后保存。在你的适配器列表上设置后。
