我们可以像这样改变旋转器的textview设置主题的样式:

styles.xml:

<style name="mySpinnerItemStyle" parent="@android:style/Widget.Holo.DropDownItem.Spinner">
    <item name="android:textSize">@dimen/_11ssp</item>
    <item name="android:textColor">@color/blue</item>
    <item name=...</item>
</style>

then

<Spinner
                    android:theme="@style/mySpinnerItemStyle"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>

如果你想改变纺纱机的textview属性编程式:

编程:

val textView = (view.getChildAt(0) as TextView)
textView.setTextColor(resources.getColor(R.color.dark_mode))

重用/更改android.R.layout资源最简单的方法就是使用定义。在Android Studio中，在Android . r.b ayout.simple_spinner_item.xml上按Ctrl + B。

它将把您带到资源文件。只需要复制资源文件，并在Package.R.layout文件夹中添加一个新的布局，并更改textview的textColor，然后像这样在适配器中调用它:

ArrayAdapter<String> adapter = new ArrayAdapter<String(Context,R.layout.spinner_item, spinnerlist);

如果所有的旋转框对它们的TextView项可能有相同的文本颜色，另一种方法是为旋转框下拉项使用自定义样式:

在res /价值/ styles.xml:

<resources>
    <style name="AppBaseTheme" parent="android:Theme.Light">
    </style>

    <style name="AppTheme" parent="AppBaseTheme">
        <item name="android:spinnerDropDownItemStyle">@style/mySpinnerItemStyle</item>
    </style>

    <style name="mySpinnerItemStyle" parent="@android:style/Widget.Holo.DropDownItem.Spinner">
        <item name="android:textColor">@color/my_spinner_text_color</item>
    </style>
</resources>

并在res/values/colors.xml中定义自定义颜色:

<color name="my_spinner_text_color">#808080</color>

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。

    String typeroutes[] = {"Select","Direct","Non Stop"};
    Spinner typeroute;

    typeroute = view.findViewById(R.id.typeroute);

    final ArrayAdapter<String> arrayAdapter5 = new ArrayAdapter<String>(
                getActivity(), android.R.layout.simple_spinner_item, typeroutes) {
            @Override
            public boolean isEnabled(int position) {
                if (position == 0) {
                    // Disable the first item from Spinner
                    // First item will be use for hint
                    return false;
                } else {
                    return true;
                }
            }

            public View getView(int position, View convertView, ViewGroup parent) {
                View v = super.getView(position, convertView, parent);
                ((TextView) v).setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
                ((TextView) v).setTextColor(Color.parseColor("#ffffff"));
                return v;
            }         ---->in this line very important so add this

            @Override
            public View getDropDownView(int position, View convertView,
                                        ViewGroup parent) {
                View view = super.getDropDownView(position, convertView, parent);
                TextView tv = (TextView) view;
                if (position == 0) {
                    // Set the hint text color gray
                    tv.setTextColor(Color.GRAY);
                } else {
                    tv.setTextColor(Color.BLACK);
                }
                return view;
            }
        };

        arrayAdapter5.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        typeroute.setAdapter(arrayAdapter5);

这就是所有的享受你的编码…

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);}
