我正在尝试更改操作栏中微调器的文本颜色。我想更改操作栏上显示的文本颜色，而不更改下拉项目的颜色

如果将简单数组适配器设置为spinner

ArrayAdapter<String> customeAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, listview_array);
actSpinner.setAdapter(customeAdapter);

然后你可以改变那样的文字颜色

actSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            CheckedTextView textView= (CheckedTextView)arg1;
             textView.setTextColor(Color.GREEN);
            System.err.println("arg2="+ arg2);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
        }
    });

或者您可以使用微调器自定义操作栏

getActionBar().setDisplayShowCustomEnabled(true);
    View view = getLayoutInflater().inflate(R.layout.spineer_view_layout, null);
    Spinner actSpinner = (Spinner) view.findViewById(R.id.spinner_action_bar);
    getActionBar().setCustomView(view);
    MyCustomeAdapter customeAdapter = new MyCustomeAdapter(this, listview_array);
    actSpinner.setAdapter(customeAdapter);
    actSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            LinearLayout linearLayout = (LinearLayout )arg1;
             TextView textView =(TextView) linearLayout.getChildAt(0);
             textView .setTextColor(Color.GREEN);
            System.err.println("arg2="+ arg2);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
        }
    });

spinner_action_bar

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal" >
<Spinner
    android:id="@+id/spinner_action_bar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />
</LinearLayout>

这是Custome Adpater的getView

@Override
public View getView(int position, View convertView, ViewGroup arg2) {
    LayoutInflater layoutInflater = (LayoutInflater) activity
            .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    ViewHolder holder = null;
    if (convertView == null) {
        holder = new ViewHolder();
        convertView = layoutInflater.inflate(
                R.layout.adapter_offer_item_layout, null);
        holder.descritpionTextView = (TextView) convertView.findViewById(R.id.value);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    holder.descritpionTextView.setText(listview_array[position]);

    return convertView;
}
private class ViewHolder {
    TextView descritpionTextView;
}

adapter_offer_item_layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/value"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

</LinearLayout>
